arm64: Ensure fpsimd support is ready before userspace is active
We register the pm/hotplug callbacks for FPSIMD as late_initcall, which happens after the userspace is active (from initramfs via populate_rootfs, a rootfs_initcall). Make sure we are ready even before the userspace could potentially use it, by promoting to a core_initcall.

arm64: Ensure the instruction emulation is ready for userspace
We trap and emulate some instructions (e.g, mrs, deprecated instructions) for the userspace. However the handlers for these are registered as late_initcalls and the userspace could be up and running from the initramfs by that time (with populate_rootfs, which is a rootfs_initcall()). This could cause problems for the early applications ending up in failure like : [ 11.152061] modprobe[93]: undefined instruction: pc=0000ffff8ca48ff4 This patch promotes the specific calls to core_initcalls, which are guaranteed to be completed before we hit userspace.

arm64: Use larger stacks when KASAN is selected
AddressSanitizer instrumentation can significantly bloat the stack, and with GCC 7 this can result in stack overflows at boot time in some configurations. We can avoid this by doubling our stack size when KASAN is in use, as is already done on x86 (and has been since KASAN was introduced). Regardless of other patches to decrease KASAN's stack utilization, kernels built with KASAN will always require more stack space than those built without, and we should take this into account.

arm64: fault: Route pte translation faults via do_translation_fault
We currently route pte translation faults via do_page_fault, which elides the address check against TASK_SIZE before invoking the mm fault handling code. However, this can cause issues with the path walking code in conjunction with our word-at-a-time implementation because load_unaligned_zeropad can end up faulting in kernel space if it reads across a page boundary and runs into a page fault (e.g. by attempting to read from a guard region). In the case of such a fault, load_unaligned_zeropad has registered a fixup to shift the valid data and pad with zeroes, however the abort is reported as a level 3 translation fault and we dispatch it straight to do_page_fault, despite it being a kernel address. This results in calling a sleeping function from atomic context: BUG: sleeping function called from invalid context at arch/arm64/mm/fault.c:313 in_atomic(): 0, irqs_disabled(): 0, pid: 10290 Internal error: Oops - BUG: 0 [#1] PREEMPT SMP [...] [<ffffff8e016cd0cc>] ___might_sleep+0x134/0x144 [<ffffff8e016cd158>] __might_sleep+0x7c/0x8c [<ffffff8e016977f0>] do_page_fault+0x140/0x330 [<ffffff8e01681328>] do_mem_abort+0x54/0xb0 Exception stack(0xfffffffb20247a70 to 0xfffffffb20247ba0) [...] [<ffffff8e016844fc>] el1_da+0x18/0x78 [<ffffff8e017f399c>] path_parentat+0x44/0x88 [<ffffff8e017f4c9c>] filename_parentat+0x5c/0xd8 [<ffffff8e017f5044>] filename_create+0x4c/0x128 [<ffffff8e017f59e4>] SyS_mkdirat+0x50/0xc8 [<ffffff8e01684e30>] el0_svc_naked+0x24/0x28 Code: 36380080 d5384100 f9400800 9402566d (d4210000) ---[ end trace 2d01889f2bca9b9f ]--- Fix this by dispatching all translation faults to do_translation_faults, which avoids invoking the page fault logic for faults on kernel addresses.

arm64: mm: Use READ_ONCE when dereferencing pointer to pte table
On kernels built with support for transparent huge pages, different CPUs
can access the PMD concurrently due to e.g. fast GUP or page_vma_mapped_walk
and they must take care to use READ_ONCE to avoid value tearing or caching
of stale values by the compiler. Unfortunately, these functions call into
our pgtable macros, which don't use READ_ONCE, and compiler caching has
been observed to cause the following crash during ext4 writeback:
PC is at check_pte+0x20/0x170
LR is at page_vma_mapped_walk+0x2e0/0x540
[...]
Process doio (pid: 2463, stack limit = 0xffff00000f2e8000)
Call trace:

[<ffff0000082332b4>] SyS_msync+0x194/0x1e8
This is because page_vma_mapped_walk loads the PMD twice before calling
pte_offset_map: the first time without READ_ONCE (where it gets all zeroes
due to a concurrent pmdp_invalidate) and the second time with READ_ONCE
(where it sees a valid table pointer due to a concurrent pmd_populate).
However, the compiler inlines everything and caches the first value in
a register, which is subsequently used in pte_offset_phys which returns
a junk pointer that is later dereferenced when attempting to access the
relevant pte.
This patch fixes the issue by using READ_ONCE in pte_offset_phys to ensure
that a stale value is not used. Whilst this is a point fix for a known
failure (and simple to backport), a full fix moving all of our page table
accessors over to {READ,WRITE}_ONCE and consistently using READ_ONCE in
page_vma_mapped_walk is in the works for a future kernel release.

arm64: Make sure SPsel is always set
When the kernel is entered at EL2 on an ARMv8.0 system, we construct the EL1 pstate and make sure this uses the the EL1 stack pointer (we perform an exception return to EL1h). But if the kernel is either entered at EL1 or stays at EL2 (because we're on a VHE-capable system), we fail to set SPsel, and use whatever stack selection the higher exception level has choosen for us. Let's not take any chance, and make sure that SPsel is set to one before we decide the mode we're going to run in.

arm64: stacktrace: avoid listing stacktrace functions in stacktrace
The stacktraces always begin as follows:
[<c00117b4>] save_stack_trace_tsk+0x0/0x98
[<c0011870>] save_stack_trace+0x24/0x28
...
This is because the stack trace code includes the stack frames for
itself. This is incorrect behaviour, and also leads to "skip" doing the
wrong thing (which is the number of stack frames to avoid recording.)
Perversely, it does the right thing when passed a non-current thread.
Fix this by ensuring that we have a known constant number of frames
above the main stack trace function, and always skip these.
This was fixed for arch arm by commit

Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull namespace updates from Eric Biederman:
"Life has been busy and I have not gotten half as much done this round
as I would have liked. I delayed it so that a minor conflict
resolution with the mips tree could spend a little time in linux-next
before I sent this pull request.
This includes two long delayed user namespace changes from Kirill
Tkhai. It also includes a very useful change from Serge Hallyn that
allows the security capability attribute to be used inside of user
namespaces. The practical effect of this is people can now untar
tarballs and install rpms in user namespaces. It had been suggested to
generalize this and encode some of the namespace information
information in the xattr name. Upon close inspection that makes the
things that should be hard easy and the things that should be easy
more expensive.
Then there is my bugfix/cleanup for signal injection that removes the
magic encoding of the siginfo union member from the kernel internal
si_code. The mips folks reported the case where I had used FPE_FIXME
me is impossible so I have remove FPE_FIXME from mips, while at the
same time including a return statement in that case to keep gcc from
complaining about unitialized variables.
I almost finished the work to get make copy_siginfo_to_user a trivial
copy to user. The code is available at:
git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace.git neuter-copy_siginfo_to_user-v3
But I did not have time/energy to get the code posted and reviewed
before the merge window opened.
I was able to see that the security excuse for just copying fields
that we know are initialized doesn't work in practice there are buggy
initializations that don't initialize the proper fields in siginfo. So
we still sometimes copy unitialized data to userspace"

ARM/arm64: SoC platform updates for v4.14
This branch contains platform updates for 32- and 64-bit ARM,
including defconfig updates to enable new options, drivers and
platforms. There are also a few fixes and cleanups for some existing vendors.
Some of the things worth highlighting here are:
- Enabling new crypt drivers on arm64 defconfig
- QCOM IPQ8074 clocks and pinctrl drivers on arm64 defconfig
- Debug support enabled for Renesas r8a7743
- Various config updates for Renesas platforms (sound, USB, other drivers)
- Platform support (including SMP) for TI dra762
- OMAP cleanups: Move to use generic 8250 debug_ll, removal of stale DMA code

treewide: make "nr_cpu_ids" unsigned
First, number of CPUs can't be negative number. Second, different signnnedness leads to suboptimal code in the following cases: 1) kmalloc(nr_cpu_ids * sizeof(X)); "int" has to be sign extended to size_t. 2) while (loff_t *pos < nr_cpu_ids) MOVSXD is 1 byte longed than the same MOV. Other cases exist as well. Basically compiler is told that nr_cpu_ids can't be negative which can't be deduced if it is "int".

Merge branch 'kvm-ppc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/paulus/powerpc
This fix was intended for 4.13, but didn't get in because both maintainers were on vacation. Paul Mackerras: "It adds mutual exclusion between list_add_rcu and list_del_rcu calls on the kvm->arch.spapr_tce_tables list. Without this, userspace could potentially trigger corruption of the list and cause a host crash or worse." |

Merge branch 'efi-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull EFI updates from Ingo Molnar:
"The main changes in this cycle were:
- Transparently fall back to other poweroff method(s) if EFI poweroff
fails (and returns)
- Use separate PE/COFF section headers for the RX and RW parts of the
ARM stub loader so that the firmware can use strict mapping
permissions
- Add support for requesting the firmware to wipe RAM at warm reboot
- Increase the size of the random seed obtained from UEFI so CRNG
fast init can complete earlier
- Update the EFI framebuffer address if it points to a BAR that gets
moved by the PCI resource allocation code
- Enable "reset attack mitigation" of TPM environments: this is
enabled if the kernel is configured with
CONFIG_RESET_ATTACK_MITIGATION=y.
- Clang related fixes
- Misc cleanups, constification, refactoring, etc"

arm64 updates for 4.14:
- VMAP_STACK support, allowing the kernel stacks to be allocated in
the vmalloc space with a guard page for trapping stack overflows. One
of the patches introduces THREAD_ALIGN and changes the generic
alloc_thread_stack_node() to use this instead of THREAD_SIZE (no
functional change for other architectures)
- Contiguous PTE hugetlb support re-enabled (after being reverted a
couple of times). We now have the semantics agreed in the generic mm
layer together with API improvements so that the architecture code can
detect between contiguous and non-contiguous huge PTEs
- Initial support for persistent memory on ARM: DC CVAP instruction
exposed to user space (HWCAP) and the in-kernel pmem API implemented
- raid6 improvements for arm64: faster algorithm for the delta syndrome
and implementation of the recovery routines using Neon
- FP/SIMD refactoring and removal of support for Neon in interrupt
context. This is in preparation for full SVE support
- PTE accessors converted from inline asm to cmpxchg so that we can
use LSE atomics if available (ARMv8.1)
- Perf support for Cortex-A35 and A73
- Non-urgent fixes and cleanups

KVM: arm/arm64: Fix guest external abort matching
The ARM-ARM has two bits in the ESR/HSR relevant to external aborts.
A range of {I,D}FSC values (of which bit 5 is always set) and bit 9 'EA'
which provides:
> an IMPLEMENTATION DEFINED classification of External Aborts.
This bit is in addition to the {I,D}FSC range, and has an implementation
defined meaning. KVM should always ignore this bit when handling external
aborts from a guest.
Remove the ESR_ELx_EA definition and rewrite its helper
kvm_vcpu_dabt_isextabt() to check the {I,D}FSC range. This merges
kvm_vcpu_dabt_isextabt() and the recently added is_abort_sea() helper.
