arm64: avoid TLB conflict with CONFIG_RANDOMIZE_BASE
When CONFIG_RANDOMIZE_BASE is selected, we modify the page tables to remap the
kernel at a newly-chosen VA range. We do this with the MMU disabled, but do not
invalidate TLBs prior to re-enabling the MMU with the new tables. Thus the old
mappings entries may still live in TLBs, and we risk violating
Break-Before-Make requirements, leading to TLB conflicts and/or other issues.
We invalidate TLBs when we uninsall the idmap in early setup code, but prior to
this we are subject to issues relating to the Break-Before-Make violation.
Avoid these issues by invalidating the TLBs before the new mappings can be
used by the hardware.

arm64: Fix shift warning in arch/arm64/mm/dump.c
When building with 48-bit VAs and 16K page configuration, it's possible to get the following warning when building the arm64 page table dumping code: arch/arm64/mm/dump.c: In function ‘walk_pud’: arch/arm64/mm/dump.c:274:102: warning: right shift count >= width of type [-Wshift-count-overflow] This is because pud_offset(pgd, 0) performs a shift to the right by 36 while the value 0 has the type 'int' by default, therefore 32-bit. This patch modifies all the p*_offset() uses in arch/arm64/mm/dump.c to use 0UL for the address argument.

arm64: kernel: avoid literal load of virtual address with MMU off
Literal loads of virtual addresses are subject to runtime relocation when
CONFIG_RELOCATABLE=y, and given that the relocation routines run with the
MMU and caches enabled, literal loads of relocated values performed with
the MMU off are not guaranteed to return the latest value unless the
memory covering the literal is cleaned to the PoC explicitly.
So defer the literal load until after the MMU has been enabled, just like
we do for primary_switch() and secondary_switch() in head.S.

arm64: Fix NUMA build error when !CONFIG_ACPI
Since asm/acpi.h is only included by linux/acpi.h when CONFIG_ACPI is
enabled, disabling the latter leads to the following build error on
arm64:
arch/arm64/mm/numa.c: In function ‘arm64_numa_init’:
arch/arm64/mm/numa.c:395:24: error: ‘arm64_acpi_numa_init’ undeclared (first use in this function)
if (!acpi_disabled && !numa_init(arm64_acpi_numa_init))
This patch include the asm/acpi.h explicitly in arch/arm64/mm/numa.c for
the arm64_acpi_numa_init() definition.

When CONFIG_LOCALVERSION_AUTO is disabled, the version string is just a tag name (or with a '+' appended if HEAD is not a tagged commit). During the development (and especially when git-bisecting), longer version string would be helpful to identify the commit we are running. This is a default y option, so drop the unset to enable it.

arm64: hibernate: handle allocation failures
In create_safe_exec_page(), we create a copy of the hibernate exit text,
along with some page tables to map this via TTBR0. We then install the
new tables in TTBR0.
In swsusp_arch_resume() we call create_safe_exec_page() before trying a
number of operations which may fail (e.g. copying the linear map page
tables). If these fail, we bail out of swsusp_arch_resume() and return
an error code, but leave TTBR0 as-is. Subsequently, the core hibernate
code will call free_basic_memory_bitmaps(), which will free all of the
memory allocations we made, including the page tables installed in
TTBR0.
Thus, we may have TTBR0 pointing at dangling freed memory for some
period of time. If the hibernate attempt was triggered by a user
requesting a hibernate test via the reboot syscall, we may return to
userspace with the clobbered TTBR0 value.
Avoid these issues by reorganising swsusp_arch_resume() such that we
have no failure paths after create_safe_exec_page(). We also add a check
that the zero page allocation succeeded, matching what we have for other
allocations.

arm64: hibernate: avoid potential TLB conflict
In create_safe_exec_page we install a set of global mappings in TTBR0,
then subsequently invalidate TLBs. While TTBR0 points at the zero page,
and the TLBs should be free of stale global entries, we may have stale
ASID-tagged entries (e.g. from the EFI runtime services mappings) for
the same VAs. Per the ARM ARM these ASID-tagged entries may conflict
with newly-allocated global entries, and we must follow a
Break-Before-Make approach to avoid issues resulting from this.
This patch reworks create_safe_exec_page to invalidate TLBs while the
zero page is still in place, ensuring that there are no potential
conflicts when the new TTBR0 value is installed. As a single CPU is
online while this code executes, we do not need to perform broadcast TLB
maintenance, and can call local_flush_tlb_all(), which also subsumes
some barriers. The remaining assembly is converted to use write_sysreg()
and isb().
Other than this, we safely manipulate TTBRs in the hibernate dance. The
code we install as part of the new TTBR0 mapping (the hibernated
kernel's swsusp_arch_suspend_exit) installs a zero page into TTBR1,
invalidates TLBs, then installs its preferred value. Upon being restored
to the middle of swsusp_arch_suspend, the new image will call
__cpu_suspend_exit, which will call cpu_uninstall_idmap, installing the
zero page in TTBR0 and invalidating all TLB entries.

dma-mapping: use unsigned long for dma_attrs
The dma-mapping core and the implementations do not change the DMA attributes passed by pointer. Thus the pointer can point to const data. However the attributes do not have to be a bitfield. Instead unsigned long will do fine: 1. This is just simpler. Both in terms of reading the code and setting attributes. Instead of initializing local attributes on the stack and passing pointer to it to dma_set_attr(), just set the bits. 2. It brings safeness and checking for const correctness because the attributes are passed by value. Semantic patches for this change (at least most of them): virtual patch virtual context @r@ identifier f, attrs; @@ f(..., - struct dma_attrs *attrs + unsigned long attrs , ...) { ... } @@ identifier r.f; @@ f(..., - NULL + 0 ) and // Options: --all-includes virtual patch virtual context @r@ identifier f, attrs; type t; @@ t f(..., struct dma_attrs *attrs); @@ identifier r.f; @@ f(..., - NULL + 0 ) Link: http://lkml.kernel.org/r/1468399300-5399-2-git-send-email-k.kozlowski@samsung.com Signed-off-by: Krzysztof Kozlowski <k.kozlowski@samsung.com> Acked-by: Vineet Gupta <vgupta@synopsys.com> Acked-by: Robin Murphy <robin.murphy@arm.com> Acked-by: Hans-Christian Noren Egtvedt <egtvedt@samfundet.no> Acked-by: Mark Salter <msalter@redhat.com> [c6x] Acked-by: Jesper Nilsson <jesper.nilsson@axis.com> [cris] Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> [drm] Reviewed-by: Bart Van Assche <bart.vanassche@sandisk.com> Acked-by: Joerg Roedel <jroedel@suse.de> [iommu] Acked-by: Fabien Dessenne <fabien.dessenne@st.com> [bdisp] Reviewed-by: Marek Szyprowski <m.szyprowski@samsung.com> [vb2-core] Acked-by: David Vrabel <david.vrabel@citrix.com> [xen] Acked-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com> [xen swiotlb] Acked-by: Joerg Roedel <jroedel@suse.de> [iommu] Acked-by: Richard Kuo <rkuo@codeaurora.org> [hexagon] Acked-by: Geert Uytterhoeven <geert@linux-m68k.org> [m68k] Acked-by: Gerald Schaefer <gerald.schaefer@de.ibm.com> [s390] Acked-by: Bjorn Andersson <bjorn.andersson@linaro.org> Acked-by: Hans-Christian Noren Egtvedt <egtvedt@samfundet.no> [avr32] Acked-by: Vineet Gupta <vgupta@synopsys.com> [arc] Acked-by: Robin Murphy <robin.murphy@arm.com> [arm64 and dma-iommu] Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |

arm64: Fix copy-on-write referencing in HugeTLB
set_pte_at(.) will set or unset the PTE_RDONLY hardware bit before
writing the entry to the table.
This can cause problems with the copy-on-write logic in hugetlb_cow:
*) hugetlb_cow(.) called to handle a write fault on read only pte,
*) Before the copy-on-write updates the new page table a call is
made to pte_same(huge_ptep_get(ptep), pte)), to check for a race,
*) Because set_pte_at(.) changed the pte, *ptep != pte, and the
hugetlb_cow(.) code erroneously assumes that it lost the race,
*) The new page is subsequently freed without being used.
On arm64 this problem only becomes apparent when we apply:

VGIC implementation. - s390: support for trapping software breakpoints, nested virtualization (vSIE), the STHYI opcode, initial extensions for CPU model support. - MIPS: support for MIPS64 hosts (32-bit guests only) and lots of cleanups, preliminary to this and the upcoming support for hardware virtualization extensions. - x86: support for execute-only mappings in nested EPT; reduced vmexit latency for TSC deadline timer (by about 30%) on Intel hosts; support for more than 255 vCPUs. - PPC: bugfixes. The ugly bit is the conflicts. A couple of them are simple conflicts due to 4.7 fixes, but most of them are with other trees. There was definitely too much reliance on Acked-by here. Some conflicts are for KVM patches where _I_ gave my Acked-by, but the worst are for this pull request's patches that touch files outside arch/*/kvm. KVM submaintainers should probably learn to synchronize better with arch maintainers, with the latter providing topic branches whenever possible instead of Acked-by. This is what we do with arch/x86. And I should learn to refuse pull requests when linux-next sends scary signals, even if that means that submaintainers have to rebase their branches. Anyhow, here's the list: - arch/x86/kvm/vmx.c: handle_pcommit and EXIT_REASON_PCOMMIT was removed by the nvdimm tree. This tree adds handle_preemption_timer and EXIT_REASON_PREEMPTION_TIMER at the same place. In general all mentions of pcommit have to go. There is also a conflict between a stable fix and this patch, where the stable fix removed the vmx_create_pml_buffer function and its call. - virt/kvm/kvm_main.c: kvm_cpu_notifier was removed by the hotplug tree. This tree adds kvm_io_bus_get_dev at the same place. - virt/kvm/arm/vgic.c: a few final bugfixes went into 4.7 before the file was completely removed for 4.8. - include/linux/irqchip/arm-gic-v3.h: this one is entirely our fault; this is a change that should have gone in through the irqchip tree and pulled by kvm-arm. I think I would have rejected this kvm-arm pull request. The KVM version is the right one, except that it lacks GITS_BASER_PAGES_SHIFT. - arch/powerpc: what a mess. For the idle_book3s.S conflict, the KVM tree is the right one; everything else is trivial. In this case I am not quite sure what went wrong. The commit that is causing the mess ( |

arm64: KVM: Set cpsr before spsr on fault injection
We need to set cpsr before determining the spsr bank, as the bank depends on the target exception level of the injection, not the current mode of the vcpu. Normally this is one in the same (EL1), but not when we manage to trap an EL0 fault. It still doesn't really matter for the 64-bit EL0 case though, as vcpu_spsr() unconditionally uses the EL1 bank for that. However the 32-bit EL0 case gets fun, as that path will lead to the BUG() in vcpu_spsr32(). This patch fixes the assignment order and also modifies some white space in order to better group pairs of lines that have strict order.

arm64: mm: avoid fdt_check_header() before the FDT is fully mapped
As reported by Zijun, the fdt_check_header() call in __fixmap_remap_fdt() is not safe since it is not guaranteed that the FDT header is mapped completely. Due to the minimum alignment of 8 bytes, the only fields we can assume to be mapped are 'magic' and 'totalsize'. Since the OF layer is in charge of validating the FDT image, and we are only interested in making reasonably sure that the size field contains a meaningful value, replace the fdt_check_header() call with an explicit comparison of the magic field's value against the expected value.

arm64: Define AT_VECTOR_SIZE_ARCH for ARCH_DLINFO
AT_VECTOR_SIZE_ARCH should be defined with the maximum number of
NEW_AUX_ENT entries that ARCH_DLINFO can contain, but it wasn't defined
for arm64 at all even though ARCH_DLINFO will contain one NEW_AUX_ENT
for the VDSO address.
This shouldn't be a problem as AT_VECTOR_SIZE_BASE includes space for
AT_BASE_PLATFORM which arm64 doesn't use, but lets define it now and add
the comment above ARCH_DLINFO as found in several other architectures to
remind future modifiers of ARCH_DLINFO to keep AT_VECTOR_SIZE_ARCH up to
date.

arm64: relocatable: suppress R_AARCH64_ABS64 relocations in vmlinux
The linker routines that we rely on to produce a relocatable PIE binary treat it as a shared ELF object in some ways, i.e., it emits symbol based R_AARCH64_ABS64 relocations into the final binary since doing so would be appropriate when linking a shared library that is subject to symbol preemption. (This means that an executable can override certain symbols that are exported by a shared library it is linked with, and that the shared library *must* update all its internal references as well, and point them to the version provided by the executable.) Symbol preemption does not occur for OS hosted PIE executables, let alone for vmlinux, and so we would prefer to get rid of these symbol based relocations. This would allow us to simplify the relocation routines, and to strip the .dynsym, .dynstr and .hash sections from the binary. (Note that these are tiny, and are placed in the .init segment, but they clutter up the vmlinux binary.) Note that these R_AARCH64_ABS64 relocations are only emitted for absolute references to symbols defined in the linker script, all other relocatable quantities are covered by anonymous R_AARCH64_RELATIVE relocations that simply list the offsets to all 64-bit values in the binary that need to be fixed up based on the offset between the link time and run time addresses. Fortunately, GNU ld has a -Bsymbolic option, which is intended for shared libraries to allow them to ignore symbol preemption, and unconditionally bind all internal symbol references to its own definitions. So set it for our PIE binary as well, and get rid of the asoociated sections and the relocation code that processes them.

arm64: vmlinux.lds: make __rela_offset and __dynsym_offset ABSOLUTE
Due to the untyped KIMAGE_VADDR constant, the linker may not notice
that the __rela_offset and __dynsym_offset expressions are absolute
values (i.e., are not subject to relocation). This does not matter for
KASLR, but it does confuse kallsyms in relative mode, since it uses
the lowest non-absolute symbol address as the anchor point, and expects
all other symbol addresses to be within 4 GB of it.
Fix this by qualifying these expressions as ABSOLUTE() explicitly.

arm64:acpi: fix the acpi alignment exception when 'mem=' specified
When booting an ACPI enabled kernel with 'mem=x', there is the possibility that ACPI data regions from the firmware will lie above the memory limit. Ordinarily these will be removed by memblock_enforce_memory_limit(.). Unfortunately, this means that these regions will then be mapped by acpi_os_ioremap(.) as device memory (instead of normal) thus unaligned accessess will then provoke alignment faults. In this patch we adopt memblock_mem_limit_remove_map instead, and this preserves these ACPI data regions (marked NOMAP) thus ensuring that these regions are not mapped as device memory. For example, below is an alignment exception observed on ARM platform when booting the kernel with 'acpi=on mem=8G': ...
