Peter Zijlstras rework of atomics and fallbacks. This solves two problems:
1) Compilers uninline small atomic_* static inline functions which can expose them to instrumentation. 2) The instrumentation of atomic primitives was done at the architecture level while composites or fallbacks were provided at the generic level. As a result there are no uninstrumented variants of the fallbacks. Both issues were in the way of fully isolating fragile entry code pathes and especially the text poke int3 handler which is prone to an endless recursion problem when anything in that code path is about to be instrumented. This was always a problem, but got elevated due to the new batch mode updates of tracing. The solution is to mark the functions __always_inline and to flip the fallback and instrumentation so the non-instrumented variants are at the architecture level and the instrumentation is done in generic code. The latter introduces another fallback variant which will go away once all architectures have been moved over to arch_atomic_*. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAl7imyETHHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYoT0wEACcI3mDiK/9hNlfnobIJTup1E8erUdY /EZX8yFc/FgpSSKAMROu3kswZ+rSWmBEyzTJLEtBAaYU6haAuGx77AugoDHfVkYi +CEJvVEpeK7fzsgu9aTb/5B6EDUo/P1fzTFjVTK1I9M9KrGLxbkGRZWYUeX3KRZd RskRJMbp9L4oiNJNAuIP6QKoJ7PK/sL16e8oVZSQR6WW9ZH4uDZbyfl5z0xLjI7u PIsFCoDu7/ig2wpOhtAYRVsL8C6EQ8mSeEUMKeM7A7UFAkVadYB8PTmEJ/QcixW+ 5R0+cnQE/3I/n0KRwfz/7p2gzILJk/cY6XJWVoAsQb990MD2ahjZJPYI4jdknjz6 8bL/QjBq+pZwbHWOhy+IdUntIYGkyjfLKoPLdSoh+uK1kl8Jsg+AlB2lN469BV1D r0NltiCLggvtqXEDLV4YZqxie6H38gvOzPDbH8I6M34+WkOI2sM0D1P/Naqw/Wgl M1Ygx4wYG8X4zDESAYMy9tSXh5lGDIjiF6sjGTOPYWwUIeRlINfWeJkiXKnYNwv/ qTiC8ciCxhlQcDifdyfQjT3mHNcP7YpVKp317TCtU4+WxMSrW1h2SL6m6j74dNI/ P7/J6GKONeLRbt0ZQbQGjqHxSuu6kqUEu69aVs5W9+WjNEoJW1EW4vrJ3TeF5jLh 0Srl4VsyDwzuXw== =Jkzv -----END PGP SIGNATURE----- Merge tag 'locking-urgent-2020-06-11' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull atomics rework from Thomas Gleixner: "Peter Zijlstras rework of atomics and fallbacks.

locking/atomics: Flip fallbacks and instrumentation
Currently instrumentation of atomic primitives is done at the architecture level, while composites or fallbacks are provided at the generic level. The result is that there are no uninstrumented variants of the fallbacks. Since there is now need of such variants to isolate text poke from any form of instrumentation invert this ordering. Doing this means moving the instrumentation into the generic code as well as having (for now) two variants of the fallbacks. Notes: - the various *cond_read* primitives are not proper fallbacks and got moved into linux/atomic.c. No arch_ variants are generated because the base primitives smp_cond_load*() are instrumented. - once all architectures are moved over to arch_atomic_ one of the fallback variants can be removed and some 2300 lines reclaimed. - atomic_{read,set}*() are no longer double-instrumented Reported-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Peter Zijlstra (Intel) <peterz@infradead.org> Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Acked-by: Mark Rutland <mark.rutland@arm.com> Link: https://lkml.kernel.org/r/20200505134058.769149955@linutronix.de |

Pull READ/WRITE_ONCE rework from Will Deacon: "This the READ_ONCE rework I've been working on for a while, which bumps the minimum GCC version and improves code-gen on arm64 when stack protector is enabled" [ Side note: I'm _really_ tempted to raise the minimum gcc version to 4.9, so that we can just say that we require _Generic() support. That would allow us to more cleanly handle a lot of the cases where we depend on very complex macros with 'sizeof' or __builtin_choose_expr() with __builtin_types_compatible_p() etc. This branch has a workaround for sparse not handling _Generic(), either, but that was already fixed in the sparse development branch, so it's really just gcc-4.9 that we'd require. - Linus ] * 'rwonce/rework' of git://git.kernel.org/pub/scm/linux/kernel/git/will/linux: compiler_types.h: Use unoptimized __unqual_scalar_typeof for sparse compiler_types.h: Optimize __unqual_scalar_typeof compilation time compiler.h: Enforce that READ_ONCE_NOCHECK() access size is sizeof(long) compiler-types.h: Include naked type in __pick_integer_type() match READ_ONCE: Fix comment describing 2x32-bit atomicity gcov: Remove old GCC 3.4 support arm64: barrier: Use '__unqual_scalar_typeof' for acquire/release macros locking/barriers: Use '__unqual_scalar_typeof' for load-acquire macros READ_ONCE: Drop pointer qualifiers when reading from scalar types READ_ONCE: Enforce atomicity for {READ,WRITE}_ONCE() memory accesses READ_ONCE: Simplify implementations of {READ,WRITE}_ONCE() arm64: csum: Disable KASAN for do_csum() fault_inject: Don't rely on "return value" from WRITE_ONCE() net: tls: Avoid assigning 'const' pointer to non-const pointer netfilter: Avoid assigning 'const' pointer to non-const pointer compiler/gcc: Raise minimum GCC version for kernel builds to 4.8 |

This time around we have 4 lines of diff in the core framework, removing a
function that isn't used anymore. Otherwise the main new thing for the common clk framework is that it is selectable in the Kconfig language now. Hopefully this will let clk drivers and clk consumers be testable on more than the architectures that support the clk framework. The goal is to introduce some Kunit tests for the framework. Outside of the core framework we have the usual set of various driver updates and non-critical fixes. The dirstat shows that the new Baikal-T1 driver is the largest addition this time around in terms of lines of code. After that the x86 (Intel), Qualcomm, and Mediatek drivers introduce many lines to support new or upcoming SoCs. After that the dirstat shows the usual suspects working on their SoC support by fixing minor bugs, correcting data and converting some of their DT bindings to YAML.

KVM: arm64: Synchronize sysreg state on injecting an AArch32 exception
On a VHE system, the EL1 state is left in the CPU most of the time, and only syncronized back to memory when vcpu_put() is called (most of the time on preemption). Which means that when injecting an exception, we'd better have a way to either: (1) write directly to the EL1 sysregs (2) synchronize the state back to memory, and do the changes there For an AArch64, we already do (1), so we are safe. Unfortunately, doing the same thing for AArch32 would be pretty invasive. Instead, we can easily implement (2) by calling the put/load architectural backends, and keep preemption disabled. We can then reload the state back into EL1. Cc: stable@vger.kernel.org Reported-by: James Morse <james.morse@arm.com> Signed-off-by: Marc Zyngier <maz@kernel.org> |

KVM: arm64: Make vcpu_cp1x() work on Big Endian hosts
AArch32 CP1x registers are overlayed on their AArch64 counterparts in the vcpu struct. This leads to an interesting problem as they are stored in their CPU-local format, and thus a CP1x register doesn't "hit" the lower 32bit portion of the AArch64 register on a BE host. To workaround this unfortunate situation, introduce a bias trick in the vcpu_cp1x() accessors which picks the correct half of the 64bit register.

arm64: vdso32: add CONFIG_THUMB2_COMPAT_VDSO
Allow the compat vdso (32b) to be compiled as either THUMB2 (default) or ARM. For THUMB2, the register r7 is reserved for the frame pointer, but code in arch/arm64/include/asm/vdso/compat_gettimeofday.h uses r7. Explicitly set -fomit-frame-pointer, since unwinding through interworked THUMB2 and ARM is unreliable anyways. See also how CONFIG_UNWINDER_FRAME_POINTER cannot be selected for CONFIG_THUMB2_KERNEL for ARCH=arm. This also helps toolchains that differ in their implicit value if the choice of -f{no-}omit-frame-pointer is left unspecified, to not error on the use of r7. 2019 Q4 ARM AAPCS seeks to standardize the use of r11 as the reserved frame pointer register, but no production compiler that can compile the Linux kernel currently implements this. We're actively discussing such a transition with ARM toolchain developers currently.

mm: consolidate pte_index() and pte_offset_*() definitions
All architectures define pte_index() as (address >> PAGE_SHIFT) & (PTRS_PER_PTE - 1) and all architectures define pte_offset_kernel() as an entry in the array of PTEs indexed by the pte_index(). For the most architectures the pte_offset_kernel() implementation relies on the availability of pmd_page_vaddr() that converts a PMD entry value to the virtual address of the page containing PTEs array. Let's move x86 definitions of the PTE accessors to the generic place in <linux/pgtable.h> and then simply drop the respective definitions from the other architectures. The architectures that didn't provide pmd_page_vaddr() are updated to have that defined. The generic implementation of pte_offset_kernel() can be overridden by an architecture and alpha makes use of this because it has special ordering requirements for its version of pte_offset_kernel().

mm: don't include asm/pgtable.h if linux/mm.h is already included
Patch series "mm: consolidate definitions of page table accessors", v2. The low level page table accessors (pXY_index(), pXY_offset()) are duplicated across all architectures and sometimes more than once. For instance, we have 31 definition of pgd_offset() for 25 supported architectures. Most of these definitions are actually identical and typically it boils down to, e.g. static inline unsigned long pmd_index(unsigned long address) { return (address >> PMD_SHIFT) & (PTRS_PER_PMD - 1); } static inline pmd_t *pmd_offset(pud_t *pud, unsigned long address) { return (pmd_t *)pud_page_vaddr(*pud) + pmd_index(address); } These definitions can be shared among 90% of the arches provided XYZ_SHIFT, PTRS_PER_XYZ and xyz_page_vaddr() are defined. For architectures that really need a custom version there is always possibility to override the generic version with the usual ifdefs magic. These patches introduce include/linux/pgtable.h that replaces include/asm-generic/pgtable.h and add the definitions of the page table accessors to the new header. This patch (of 12): The linux/mm.h header includes <asm/pgtable.h> to allow inlining of the functions involving page table manipulations, e.g. pte_alloc() and pmd_alloc(). So, there is no point to explicitly include <asm/pgtable.h> in the files that include <linux/mm.h>. The include statements in such cases are remove with a simple loop: for f in $(git grep -l "include <linux/mm.h>") ; do sed -i -e '/include <asm\/pgtable.h>/ d' $f done Signed-off-by: Mike Rapoport <rppt@linux.ibm.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Cc: Arnd Bergmann <arnd@arndb.de> Cc: Borislav Petkov <bp@alien8.de> Cc: Brian Cain <bcain@codeaurora.org> Cc: Catalin Marinas <catalin.marinas@arm.com> Cc: Chris Zankel <chris@zankel.net> Cc: "David S.

arm64: add show_stack_loglvl()
Currently, the log-level of show_stack() depends on a platform realization. It creates situations where the headers are printed with lower log level or higher than the stacktrace (depending on a platform or user). Furthermore, it forces the logic decision from user to an architecture side. In result, some users as sysrq/kdb/etc are doing tricks with temporary rising console_loglevel while printing their messages. And in result it not only may print unwanted messages from other CPUs, but also omit printing at all in the unlucky case where the printk() was deferred. Introducing log-level parameter and KERN_UNSUPPRESSED [1] seems an easier approach than introducing more printk buffers. Also, it will consolidate printings with headers.

arm64: add loglvl to dump_backtrace()
Currently, the log-level of show_stack() depends on a platform realization. It creates situations where the headers are printed with lower log level or higher than the stacktrace (depending on a platform or user). Furthermore, it forces the logic decision from user to an architecture side. In result, some users as sysrq/kdb/etc are doing tricks with temporary rising console_loglevel while printing their messages. And in result it not only may print unwanted messages from other CPUs, but also omit printing at all in the unlucky case where the printk() was deferred. Introducing log-level parameter and KERN_UNSUPPRESSED [1] seems an easier approach than introducing more printk buffers. Also, it will consolidate printings with headers. Add log level argument to dump_backtrace() as a preparation for introducing show_stack_loglvl().

KVM: arm64: Remove host_cpu_context member from vcpu structure
For very long, we have kept this pointer back to the per-cpu host state, despite having working per-cpu accessors at EL2 for some time now. Recent investigations have shown that this pointer is easy to abuse in preemptible context, which is a sure sign that it would better be gone. Not to mention that a per-cpu pointer is faster to access at all times.

Sparse complains that __hyp_this_cpu_ptr() returns something that is flagged noderef and not in the correct address space (both being the result of the __percpu annotation). Pretend that __hyp_this_cpu_ptr() knows what it is doing by forcefully casting the pointer with __kernel __force. Signed-off-by: Marc Zyngier <maz@kernel.org> |

KVM: arm64: Handle PtrAuth traps early
The current way we deal with PtrAuth is a bit heavy handed: - We forcefully save the host's keys on each vcpu_load() - Handling the PtrAuth trap forces us to go all the way back to the exit handling code to just set the HCR bits Overall, this is pretty cumbersome. A better approach would be to handle it the same way we deal with the FPSIMD registers: - On vcpu_load() disable PtrAuth for the guest - On first use, save the host's keys, enable PtrAuth in the guest Crucially, this can happen as a fixup, which is done very early on exit. We can then reenter the guest immediately without leaving the hypervisor role. Another thing is that it simplify the rest of the host handling: exiting all the way to the host means that the only possible outcome for this trap is to inject an UNDEF.

KVM: arm64: Save the host's PtrAuth keys in non-preemptible context
When using the PtrAuth feature in a guest, we need to save the host's keys before allowing the guest to program them. For that, we dump them in a per-CPU data structure (the so called host context). But both call sites that do this are in preemptible context, which may end up in disaster should the vcpu thread get preempted before reentering the guest. Instead, save the keys eagerly on each vcpu_load(). This has an increased overhead, but is at least safe.

KVM: arm64: Stop save/restoring ACTLR_EL1
KVM sets HCR_EL2.TACR via HCR_GUEST_FLAGS. This means ACTLR* accesses from the guest are always trapped, and always return the value in the sys_regs array. The guest can't change the value of these registers, so we are save restoring the reset value, which came from the host. Stop save/restoring this register. Keep the storage for this register in sys_regs[] as this is how the value is exposed to user-space, removing it would break migration.

KVM: arm64: Stop writing aarch32's CSSELR into ACTLR
aarch32 has pairs of registers to access the high and low parts of 64bit registers. KVM has a union of 64bit sys_regs[] and 32bit copro[]. The 32bit accessors read the high or low part of the 64bit sys_reg[] value through the union. Both sys_reg_descs[] and cp15_regs[] list access_csselr() as the accessor for CSSELR{,_EL1}. access_csselr() is only aware of the 64bit sys_regs[], and expects r->reg to be 'CSSELR_EL1' in the enum, index 2 of the 64bit array. cp15_regs[] uses the 32bit copro[] alias of sys_regs[]. Here CSSELR is c0_CSSELR which is the same location in sys_reg[]. r->reg is 'c0_CSSELR', index 4 in the 32bit array. access_csselr() uses the 32bit r->reg value to access the 64bit array, so reads and write the wrong value. sys_regs[4], is ACTLR_EL1, which is subsequently save/restored when we enter the guest. ACTLR_EL1 is supposed to be read-only for the guest. This register only affects execution at EL1, and the host's value is restored before we return to host EL1. Convert the 32bit register index back to the 64bit version.

IOMMU Updates for Linux v5.8
Including: - A big part of this is a change in how devices get connected to IOMMUs in the core code. It contains the change from the old add_device()/remove_device() to the new probe_device()/release_device() call-backs. As a result functionality that was previously in the IOMMU drivers has been moved to the IOMMU core code, including IOMMU group allocation for each device. The reason for this change was to get more robust allocation of default domains for the iommu groups. A couple of fixes were necessary after this was merged into the IOMMU tree, but there are no known bugs left. The last fix is applied on-top of the merge commit for the topic branches. - Removal of the driver private domain handling in the Intel VT-d driver. This was fragile code and I am glad it is gone now. - More Intel VT-d updates from Lu Baolu: - Nested Shared Virtual Addressing (SVA) support to the Intel VT-d driver - Replacement of the Intel SVM interfaces to the common IOMMU SVA API - SVA Page Request draining support - ARM-SMMU Updates from Will: - Avoid mapping reserved MMIO space on SMMUv3, so that it can be claimed by the PMU driver - Use xarray to manage ASIDs on SMMUv3 - Reword confusing shutdown message - DT compatible string updates - Allow implementations to override the default domain type - A new IOMMU driver for the Allwinner Sun50i platform - Support for ATS gets disabled for untrusted devices (like Thunderbolt devices). This includes a PCI patch, acked by Bjorn. - Some cleanups to the AMD IOMMU driver to make more use of IOMMU core features. - Unification of some printk formats in the Intel and AMD IOMMU drivers and in the IOVA code. - Updates for DT bindings - A number of smaller fixes and cleanups. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEr9jSbILcajRFYWYyK/BELZcBGuMFAl7eX5gACgkQK/BELZcB GuOMMQ//Si8h3uC4QhTmeNM6OwYpTcImMuCtqOebVDOJYWfbjGb4U2ZvDSUu4r7u KGj66pWBq9kciKaM5HcLnWNg4iNNG+iZHwYSOy2DAOdPorWh40aM/Obozdd4D4eK sXt4uy1JEQem/Bm4eTwmvaJV5/riyK6xn1HVocPejstGSJCh4kal/bYuhj415qEa LLrN0AcitoPaSRl4Pl7/wEtesk+Az0g94jY9qDhtxIQJXWlAwO25s+rIPy4S7QuW WAFGU+Xp+J7WC3hQm6nHKQtURIqPHtqozT9Flws9YETuyeKwn47GRitMiAXZsy7R t+kj1cHyglEhe2hdPnJBSFIjyrO3cCrV7CUVryJHigPCQOaQLjoEegThQCYU3VQu FPRBX+bp4haHeo3BCBy2jQv4JZrPFkTVXeVEtpMRDOoJLb2OKaI34xbOvGy6dMM0 dFtpbAW2IjHuneJaQCbJIC+jaEYii8mr3Zwok4LS8u8Sy+7PPSKmt6Tti3enD8+C pBB/0CxNJvQFhl13s6oI8NHTT9D6cPTbjxc2Gfc3UuKyyWsz+eR54gRhaBi0FypA p6syMosNVjjOaHFd5K5gsbpUFCC3X/drIhqeXRLgQ51mqfkNZMuBBtiyLWTk7iJd CK+1f2aqtBrpUdSNjTzE/XmR+AhjIn2oIcG/7jPCgYXQoSGM2Sg= =a4z4 -----END PGP SIGNATURE----- Merge tag 'iommu-updates-v5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu Pull iommu updates from Joerg Roedel: "A big part of this is a change in how devices get connected to IOMMUs in the core code.

Split the old READ_IMPLIES_EXEC workaround from executable PT_GNU_STACK
now that toolchains long support PT_GNU_STACK marking and there's no need anymore to force modern programs into having all its user mappings executable instead of only the stack and the PROT_EXEC ones. Disable that automatic READ_IMPLIES_EXEC forcing on x86-64 and arm64. Add tables documenting how READ_IMPLIES_EXEC is handled on x86-64, arm and arm64.

ARM: SoC changes for v5.8
One new platform gets added, the Realtek RTD1195, which is an older Cortex-a7 based relative of the RTD12xx chips that are already supported in arch/arm64. The platform may also be extended to support running 32-bit kernels on those 64-bit chips for memory-constrained machines. In the Renesas shmobile platform, we gain support for "RZ/G1H" or R8A7742, an eight-core chip based on Cortex-A15 and Cortex-A7 cores, originally released in 2016 as one of the last high-end 32-bit designs. There is ongoing cleanup for the integrator, tegra, imx, and omap2 platforms, with integrator getting very close to the goal of having zero code in arch/arm/, and omap2 moving more of the chip specifics from old board code into device tree files. The Versatile Express platform is made more modular, with built-in drivers now becoming loadable modules. This is part of a greater effort for the Android OS to have a common kernel binary for all platforms and any platform specific code in loadable modules. The PXA platform drops support for Compulab's pxa2xx boards that had rather unusual flash and PCI drivers but no known users remaining. All device drivers specific to those boards can now get removed as well. Across platforms, there is ongoing cleanup, with Geert and Rob revisiting some a lot of Kconfig options.

mm/debug: add tests validating architecture page table helpers
This adds tests which will validate architecture page table helpers and other accessors in their compliance with expected generic MM semantics. This will help various architectures in validating changes to existing page table helpers or addition of new ones. This test covers basic page table entry transformations including but not limited to old, young, dirty, clean, write, write protect etc at various level along with populating intermediate entries with next page table page and validating them. Test page table pages are allocated from system memory with required size and alignments. The mapped pfns at page table levels are derived from a real pfn representing a valid kernel text symbol. This test gets called via late_initcall(). This test gets built and run when CONFIG_DEBUG_VM_PGTABLE is selected. Any architecture, which is willing to subscribe this test will need to select ARCH_HAS_DEBUG_VM_PGTABLE. For now this is limited to arc, arm64, x86, s390 and powerpc platforms where the test is known to build and run successfully Going forward, other architectures too can subscribe the test after fixing any build or runtime problems with their page table helpers. Folks interested in making sure that a given platform's page table helpers conform to expected generic MM semantics should enable the above config which will just trigger this test during boot. Any non conformity here will be reported as an warning which would need to be fixed. This test will help catch any changes to the agreed upon semantics expected from generic MM and enable platforms to accommodate it thereafter.
