arm, arm64: move free_unused_memmap() to generic mm
ARM and ARM64 free unused parts of the memory map just before the initialization of the page allocator. To allow holes in the memory map both architectures overload pfn_valid() and define HAVE_ARCH_PFN_VALID. Allowing holes in the memory map for FLATMEM may be useful for small machines, such as ARC and m68k and will enable those architectures to cease using DISCONTIGMEM and still support more than one memory bank. Move the functions that free unused memory map to generic mm and enable them in case HAVE_ARCH_PFN_VALID=y.

arm: remove CONFIG_ARCH_HAS_HOLES_MEMORYMODEL
ARM is the only architecture that defines CONFIG_ARCH_HAS_HOLES_MEMORYMODEL which in turn enables memmap_valid_within() function that is intended to verify existence of struct page associated with a pfn when there are holes in the memory map. However, the ARCH_HAS_HOLES_MEMORYMODEL also enables HAVE_ARCH_PFN_VALID and arch-specific pfn_valid() implementation that also deals with the holes in the memory map. The only two users of memmap_valid_within() call this function after a call to pfn_valid() so the memmap_valid_within() check becomes redundant. Remove CONFIG_ARCH_HAS_HOLES_MEMORYMODEL and memmap_valid_within() and rely entirely on ARM's implementation of pfn_valid() that is now enabled unconditionally.

The new preemtible kmap_local() implementation:
- Consolidate all kmap_atomic() internals into a generic implementation
which builds the base for the kmap_local() API and make the
kmap_atomic() interface wrappers which handle the disabling/enabling of
preemption and pagefaults.
- Switch the storage from per-CPU to per task and provide scheduler
support for clearing mapping when scheduling out and restoring them
when scheduling back in.
- Merge the migrate_disable/enable() code, which is also part of the
scheduler pull request. This was required to make the kmap_local()
interface available which does not disable preemption when a mapping
is established. It has to disable migration instead to guarantee that
the virtual address of the mapped slot is the same accross preemption.
- Provide better debug facilities: guard pages and enforced utilization
of the mapping mechanics on 64bit systems when the architecture allows
it.
- Provide the new kmap_local() API which can now be used to cleanup the
kmap_atomic() usage sites all over the place. Most of the usage sites
do not require the implicit disabling of preemption and pagefaults so
the penalty on 64bit and 32bit non-highmem systems is removed and quite
some of the code can be simplified. A wholesale conversion is not
possible because some usage depends on the implicit side effects and
some need to be cleaned up because they work around these side effects.
The migrate disable side effect is only effective on highmem systems
and when enforced debugging is enabled. On 64bit and 32bit non-highmem
systems the overhead is completely avoided.

arm64 updates for 5.11:
- Expose tag address bits in siginfo. The original arm64 ABI did not
expose any of the bits 63:56 of a tagged address in siginfo. In the
presence of user ASAN or MTE, this information may be useful. The
implementation is generic to other architectures supporting tags (like
SPARC ADI, subject to wiring up the arch code). The user will have to
opt in via sigaction(SA_EXPOSE_TAGBITS) so that the extra bits, if
available, become visible in si_addr.
- Default to 32-bit wide ZONE_DMA. Previously, ZONE_DMA was set to the
lowest 1GB to cope with the Raspberry Pi 4 limitations, to the
detriment of other platforms. With these changes, the kernel scans the
Device Tree dma-ranges and the ACPI IORT information before deciding
on a smaller ZONE_DMA.
- Strengthen READ_ONCE() to acquire when CONFIG_LTO=y. When building
with LTO, there is an increased risk of the compiler converting an
address dependency headed by a READ_ONCE() invocation into a control
dependency and consequently allowing for harmful reordering by the
CPU.
- Add CPPC FFH support using arm64 AMU counters.
- set_fs() removal on arm64. This renders the User Access Override (UAO)
ARMv8 feature unnecessary.
- Perf updates: PMU driver for the ARM DMC-620 memory controller, sysfs
identifier file for SMMUv3, stop event counters support for i.MX8MP,
enable the perf events-based hard lockup detector.
- Reorganise the kernel VA space slightly so that 52-bit VA
configurations can use more virtual address space.
- Improve the robustness of the arm64 memory offline event notifier.
- Pad the Image header to 64K following the EFI header definition
updated recently to increase the section alignment to 64K.
- Support CONFIG_CMDLINE_EXTEND on arm64.
- Do not use tagged PC in the kernel (TCR_EL1.TBID1==1), freeing up 8
bits for PtrAuth.
- Switch to vmapped shadow call stacks.
- Miscellaneous clean-ups.

Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 updates from Catalin Marinas:
- Expose tag address bits in siginfo. The original arm64 ABI did not
expose any of the bits 63:56 of a tagged address in siginfo. In the
presence of user ASAN or MTE, this information may be useful. The
implementation is generic to other architectures supporting tags
(like SPARC ADI, subject to wiring up the arch code). The user will
have to opt in via sigaction(SA_EXPOSE_TAGBITS) so that the extra
bits, if available, become visible in si_addr.
- Default to 32-bit wide ZONE_DMA. Previously, ZONE_DMA was set to the
lowest 1GB to cope with the Raspberry Pi 4 limitations, to the
detriment of other platforms. With these changes, the kernel scans
the Device Tree dma-ranges and the ACPI IORT information before
deciding on a smaller ZONE_DMA.
- Strengthen READ_ONCE() to acquire when CONFIG_LTO=y. When building
with LTO, there is an increased risk of the compiler converting an
address dependency headed by a READ_ONCE() invocation into a control
dependency and consequently allowing for harmful reordering by the
CPU.
- Add CPPC FFH support using arm64 AMU counters.
- set_fs() removal on arm64. This renders the User Access Override
(UAO) ARMv8 feature unnecessary.
- Perf updates: PMU driver for the ARM DMC-620 memory controller, sysfs
identifier file for SMMUv3, stop event counters support for i.MX8MP,
enable the perf events-based hard lockup detector.
- Reorganise the kernel VA space slightly so that 52-bit VA
configurations can use more virtual address space.
- Improve the robustness of the arm64 memory offline event notifier.
- Pad the Image header to 64K following the EFI header definition
updated recently to increase the section alignment to 64K.
- Support CONFIG_CMDLINE_EXTEND on arm64.
- Do not use tagged PC in the kernel (TCR_EL1.TBID1==1), freeing up 8
bits for PtrAuth.
- Switch to vmapped shadow call stacks.
- Miscellaneous clean-ups.

ARM: keystone: remove SECTION_SIZE_BITS/MAX_PHYSMEM_BITS
These definitions are evidently left over from the days when
sparsemem settings were platform specific. This was no longer
the case when the platform got merged.
There was no warning in the past, but now the asm/sparsemem.h
header ends up being included indirectly, causing this warning:
In file included from /git/arm-soc/arch/arm/mach-keystone/keystone.c:24:
arch/arm/mach-keystone/memory.h:10:9: warning: 'SECTION_SIZE_BITS' macro redefined [-Wmacro-redefined]
#define SECTION_SIZE_BITS 34
^
arch/arm/include/asm/sparsemem.h:23:9: note: previous definition is here
#define SECTION_SIZE_BITS 28

Clearly the definitions never had any effect here, so remove them.

We can fix this by removing the ZSMALLOC_PGTABLE_MAPPING feature (which
contains the offending calling code) from zsmalloc.
Even though this option showed some amount improvement(e.g., 30%) in
some arm32 platforms, it has been headache to maintain since it have
abused APIs[1](e.g., unmap_kernel_range in atomic context).
Since we are approaching to deprecate 32bit machines and already made
the config option available for only builtin build since v5.8, lastly it
has been not default option in zsmalloc, it's time to drop the option
for better maintenance.

usb: ohci-omap: Fix descriptor conversion
There were a bunch of issues with the patch converting the
OMAP1 OSK board to use descriptors for controlling the USB
host:
- The chip label was incorrect
- The GPIO offset was off-by-one
- The code should use sleeping accessors
This patch tries to fix all issues at the same time.

crypto: arm/aes-ce - work around Cortex-A57/A72 silion errata
ARM Cortex-A57 and Cortex-A72 cores running in 32-bit mode are affected by silicon errata #1742098 and #1655431, respectively, where the second instruction of a AES instruction pair may execute twice if an interrupt is taken right after the first instruction consumes an input register of which a single 32-bit lane has been updated the last time it was modified. This is not such a rare occurrence as it may seem: in counter mode, only the least significant 32-bit word is incremented in the absence of a carry, which makes our counter mode implementation susceptible to these errata. So let's shuffle the counter assignments around a bit so that the most recent updates when the AES instruction pair executes are 128-bit wide.

kbuild: Hoist '--orphan-handling' into Kconfig
Currently, '--orphan-handling=warn' is spread out across four different architectures in their respective Makefiles, which makes it a little unruly to deal with in case it needs to be disabled for a specific linker version (in this case, ld.lld 10.0.1). To make it easier to control this, hoist this warning into Kconfig and the main Makefile so that disabling it is simpler, as the warning will only be enabled in a couple places (main Makefile and a couple of compressed boot folders that blow away LDFLAGS_vmlinx) and making it conditional is easier due to Kconfig syntax. One small additional benefit of this is saving a call to ld-option on incremental builds because we will have already evaluated it for CONFIG_LD_ORPHAN_WARN. To keep the list of supported architectures the same, introduce CONFIG_ARCH_WANT_LD_ORPHAN_WARN, which an architecture can select to gain this automatically after all of the sections are specified and size asserted. A special thanks to Kees Cook for the help text on this config.

signal: clear non-uapi flag bits when passing/returning sa_flags
Previously we were not clearing non-uapi flag bits in sigaction.sa_flags when storing the userspace-provided sa_flags or when returning them via oldact. Start doing so. This allows userspace to detect missing support for flag bits and allows the kernel to use non-uapi bits internally, as we are already doing in arch/x86 for two flag bits. Now that this change is in place, we no longer need the code in arch/x86 that was hiding these bits from userspace, so remove it. This is technically a userspace-visible behavior change for sigaction, as the unknown bits returned via oldact.sa_flags are no longer set. However, we are free to define the behavior for unknown bits exactly because their behavior is currently undefined, so for now we can define the meaning of each of them to be "clear the bit in oldact.sa_flags unless the bit becomes known in the future". Furthermore, this behavior is consistent with OpenBSD [1], illumos [2] and XNU [3] (FreeBSD [4] and NetBSD [5] fail the syscall if unknown bits are set). So there is some precedent for this behavior in other kernels, and in particular in XNU, which is probably the most popular kernel among those that I looked at, which means that this change is less likely to be a compatibility issue.

arch: move SA_* definitions to generic headers
Most architectures with the exception of alpha, mips, parisc and sparc use the same values for these flags. Move their definitions into asm-generic/signal-defs.h and allow the architectures with non-standard values to override them. Also, document the non-standard flag values in order to make it easier to add new generic flags in the future. A consequence of this change is that on powerpc and x86, the constants' values aside from SA_RESETHAND change signedness from unsigned to signed. This is not expected to impact realistic use of these constants. In particular the typical use of the constants where they are or'ed together and assigned to sa_flags (or another int variable) would not be affected.

crypto: sha - split sha.h into sha1.h and sha2.h
Currently <crypto/sha.h> contains declarations for both SHA-1 and SHA-2, and <crypto/sha3.h> contains declarations for SHA-3. This organization is inconsistent, but more importantly SHA-1 is no longer considered to be cryptographically secure. So to the extent possible, SHA-1 shouldn't be grouped together with any of the other SHA versions, and usage of it should be phased out. Therefore, split <crypto/sha.h> into two headers <crypto/sha1.h> and <crypto/sha2.h>, and make everyone explicitly specify whether they want the declarations for SHA-1, SHA-2, or both. This avoids making the SHA-1 declarations visible to files that don't want anything to do with SHA-1. It also prepares for potentially moving sha1.h into a new insecure/ or dangerous/ directory.

net: wan: Delete the DLCI / SDLA drivers
The DLCI driver (dlci.c) implements the Frame Relay protocol. However,
we already have another newer and better implementation of Frame Relay
provided by the HDLC_FR driver (hdlc_fr.c).
The DLCI driver's implementation of Frame Relay is used by only one
hardware driver in the kernel - the SDLA driver (sdla.c).
The SDLA driver provides Frame Relay support for the Sangoma S50x devices.
However, the vendor provides their own driver (along with their own
multi-WAN-protocol implementations including Frame Relay), called WANPIPE.
I believe most users of the hardware would use the vendor-provided WANPIPE
driver instead.
(The WANPIPE driver was even once in the kernel, but was deleted in

ARM: SoC fixes for v5.10, part 2
Around one third of the fixes this time are for dts files that list their ethernet controller as using 'phy-mode="rgmii"' but are changed to 'phy-mode="rgmii-id"' now, because the PHY drivers (realtek, ksz9031, dp83867, ...) now configure the internal delay based on that when they used to stay on the hardware default. The long story is archived at https://lore.kernel.org/netdev/CAMj1kXEEF_Un-4NTaD5iUN0NoZYaJQn-rPediX0S6oRiuVuW-A@mail.gmail.com/ I was trying to hold off on the bugfixes until there was a solution that would avoid breaking all boards, but that does not seem to be happening any time soon, so I am now sending the correct version of the dts files to ensure that at least these machines can use their network devices again. The other changes this time are: - Updating the MAINTAINER lists for Allwinner and Samsung SoCs - Multiple i.MX8MN machines get updates for their CPU operating points to match the data sheet - A revert for a dts patch that caused a regression in USB support on Odroid U3 - Two fixes for the AMD Tee driver, addressing a memory leak and missing locking - Mark the network subsystem on qoriq-fman3 as cache coherent for correctness as better performance. - Minor dts fixes elsewhere, addressing dtc warnings and similar problems Signed-off-by: Arnd Bergmann <arnd@arndb.de> -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEo6/YBQwIrVS28WGKmmx57+YAGNkFAl+yqIMACgkQmmx57+YA GNniQxAAnv8RAPMt8Jv4tyA0RshkD5+6JtgD6KfYccbI5Df+1O3YKJm90SA4Tpwg 03GHpAsgIs9SYNP7gSs9HPYCOJwC4rmgmfbnbB4Ezpr+oe+w6C8FI7160BBgb4f8 3/0LC6YyF48SPJ40lF/GOnTLbD5hxGw08oHCh/oL+b+bwn21JZoXAtkloCz8o6Ax u98G5MAaJhoTFaE3jq+8F1t6PNJ518HTulzod7uLAjn4iQtAmE96J7q9ncwcGu6a HNNcAGuz7X5QfEwWuAJai8eWvtMyGLvB5x1LXjjCNKgIqG+cD1tqpQ3FMedi36fg N+fxMxTJKuvBaQ83h/yyNk4/W3h6ddTbuEH0s320xSP5eiZ4r+/2Ry3WPHxHR3Rq YYDFbN6I19pQmgedJhgEmUEJXMcyId4SqN85l+uB58lOzu4zGf4WwVd+CBnEoIu3 wMGHbwruP1t+4hvZjiga53iOzWTR2EzTYkKxfDrV3mPZY6gmov5Xjb0JZNl164WF 0IJEa61HKf/ueJ5UNwWXpObNyD9rD2Ucugvok/KC1s06NFKjebGK4JhwChxMN0Sk baynLGSDe8utENrYgW+KmgZTQHTEICimT5ogW7H+W3trXqxvTKpwCsv5zZM0e238 vULK/YGZLQZaZrxsCG2WylL6SlJQfptMy8wzOoKmbgTOkcsBasA= =Qgm/ -----END PGP SIGNATURE----- Merge tag 'arm-soc-fixes-v5.10-2' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc Pull ARM SoC fixes from Arnd Bergmann: "Around one third of the fixes this time are for dts files that list their ethernet controller as using 'phy-mode="rgmii"' but are changed to 'phy-mode="rgmii-id"' now, because the PHY drivers (realtek, ksz9031, dp83867, ...) now configure the internal delay based on that when they used to stay on the hardware default.

arch: pgtable: define MAX_POSSIBLE_PHYSMEM_BITS where needed
Stefan Agner reported a bug when using zsram on 32-bit Arm machines with RAM above the 4GB address boundary: Unable to handle kernel NULL pointer dereference at virtual address 00000000 pgd = a27bd01c [00000000] *pgd=236a0003, *pmd=1ffa64003 Internal error: Oops: 207 [#1] SMP ARM Modules linked in: mdio_bcm_unimac(+) brcmfmac cfg80211 brcmutil raspberrypi_hwmon hci_uart crc32_arm_ce bcm2711_thermal phy_generic genet CPU: 0 PID: 123 Comm: mkfs.ext4 Not tainted 5.9.6 #1 Hardware name: BCM2711 PC is at zs_map_object+0x94/0x338 LR is at zram_bvec_rw.constprop.0+0x330/0xa64 pc : [<c0602b38>] lr : [<c0bda6a0>] psr: 60000013 sp : e376bbe0 ip : 00000000 fp : c1e2921c r10: 00000002 r9 : c1dda730 r8 : 00000000 r7 : e8ff7a00 r6 : 00000000 r5 : 02f9ffa0 r4 : e3710000 r3 : 000fdffe r2 : c1e0ce80 r1 : ebf979a0 r0 : 00000000 Flags: nZCv IRQs on FIQs on Mode SVC_32 ISA ARM Segment user Control: 30c5383d Table: 235c2a80 DAC: fffffffd Process mkfs.ext4 (pid: 123, stack limit = 0x495a22e6) Stack: (0xe376bbe0 to 0xe376c000) As it turns out, zsram needs to know the maximum memory size, which is defined in MAX_PHYSMEM_BITS when CONFIG_SPARSEMEM is set, or in MAX_POSSIBLE_PHYSMEM_BITS on the x86 architecture. The same problem will be hit on all 32-bit architectures that have a physical address space larger than 4GB and happen to not enable sparsemem and include asm/sparsemem.h from asm/pgtable.h. After the initial discussion, I suggested just always defining MAX_POSSIBLE_PHYSMEM_BITS whenever CONFIG_PHYS_ADDR_T_64BIT is set, or provoking a build error otherwise. This addresses all configurations that can currently have this runtime bug, but leaves all other configurations unchanged. I looked up the possible number of bits in source code and datasheets, here is what I found: - on ARC, CONFIG_ARC_HAS_PAE40 controls whether 32 or 40 bits are used - on ARM, CONFIG_LPAE enables 40 bit addressing, without it we never support more than 32 bits, even though supersections in theory allow up to 40 bits as well. - on MIPS, some MIPS32r1 or later chips support 36 bits, and MIPS32r5 XPA supports up to 60 bits in theory, but 40 bits are more than anyone will ever ship - On PowerPC, there are three different implementations of 36 bit addressing, but 32-bit is used without CONFIG_PTE_64BIT - On RISC-V, the normal page table format can support 34 bit addressing. There is no highmem support on RISC-V, so anything above 2GB is unused, but it might be useful to eventually support CONFIG_ZRAM for high pages. Fixes: |
