      Pull x86 fixes from Thomas Gleixner:
       "Another set of x86 related updates:
      
         - Fix the long broken x32 version of the IPC user space headers which
           was noticed by Arnd Bergman in course of his ongoing y2038 work.
           GLIBC seems to have non broken private copies of these headers so
           this went unnoticed.
      
         - Two microcode fixlets which address some more fallout from the
           recent modifications in that area:
      
            - Unconditionally save the microcode patch, which was only saved
              when CPU_HOTPLUG was enabled causing failures in the late
              loading mechanism
      
            - Make the later loader synchronization finally work under all
              circumstances. It was exiting early and causing timeout failures
              due to a missing synchronization point.
      
         - Do not use mwait_play_dead() on AMD systems to prevent excessive
           power consumption as the CPU cannot go into deep power states from
           there.
      
         - Address an annoying sparse warning due to lost type qualifiers of
           the vmemmap and vmalloc base address constants.
      
         - Prevent reserving crash kernel region on Xen PV as this leads to
           the wrong perception that crash kernels actually work there which
           is not the case. Xen PV has its own crash mechanism handled by the
           hypervisor.
      
         - Add missing TLB cpuid values to the table to make the printout on
           certain machines correct.
      
         - Enumerate the new CLDEMOTE instruction
      
         - Fix an incorrect SPDX identifier
      
         - Remove stale macros"

           caused a bunch of interesting regressions:

      <linux/stringhash.h>: fix end_name_hash() for 64bit long · 19b9ad67
      Amir Goldstein authored
      The comment claims that this helper will try not to loose bits, but for
      64bit long it looses the high bits before hashing 64bit long into 32bit
      int.  Use the helper hash_long() to do the right thing for 64bit long.
      For 32bit long, there is no change.
      
      All the callers of end_name_hash() either assign the result to
      qstr->hash, which is u32 or return the result as an int value (e.g.
      full_name_hash()).  Change the helper return type to int to conform to
      its users.
      
      [ It took me a while to apply this, because my initial reaction to it
        was - incorrectly - that it could make for slower code.
      
        After having looked more at it, I take back all my complaints about
        the patch, Amir was right and I was mis-reading things or just being
        stupid.
      
        I also don't worry too much about the possible performance impact of
        this on 64-bit, since most architectures that actually care about
        performance end up not using this very much (the dcache code is the
        most performance-critical, but the word-at-a-time case uses its own
        hashing anyway).
      
        So this ends up being mostly used for filesystems that do their own
        degraded hashing (usually because they want a case-insensitive
        comparison function).
      
        A _tiny_ worry remains, in that not everybody uses DCACHE_WORD_ACCESS,
        and then this potentially makes things more expensive on 64-bit
        architectures with slow or lacking multipliers even for the normal
        case.
      
        That said, realistically the only such architecture I can think of is
        PA-RISC. Nobody really cares about performance on that, it's more of a
        "look ma, I've got warts^W an odd machine" platform.
      
        So the patch is fine, and all my initial worries were just misplaced
        from not looking at this properly.   - Linus ]

        Our memory hot-unplug path wasn't flushing the cache before removing

        metal.
      
        Three fixes for the NPU code that supports devices connected via
        NVLink (ie. GPUs). The main one tweaks the TLB flush algorithm to
        avoid soft lockups for large flushes.
      
        A fix for our memory error handling where we would loop infinitely,

      kvm: apic: Flush TLB after APIC mode/address change if VPIDs are in use · a468f2db
      Junaid Shahid authored
      Currently, KVM flushes the TLB after a change to the APIC access page
      address or the APIC mode when EPT mode is enabled. However, even in
      shadow paging mode, a TLB flush is needed if VPIDs are being used, as
      specified in the Intel SDM Section 29.4.5.
      
      So replace vmx_flush_tlb_ept_only() with vmx_flush_tlb(), which will
      flush if either EPT or VPIDs are in use.

      x86/entry/64/compat: Preserve r8-r11 in int $0x80 · 8bb2610b
      Andy Lutomirski authored
      32-bit user code that uses int $80 doesn't care about r8-r11.  There is,
      however, some 64-bit user code that intentionally uses int $0x80 to invoke
      32-bit system calls.  From what I've seen, basically all such code assumes
      that r8-r15 are all preserved, but the kernel clobbers r8-r11.  Since I
      doubt that there's any code that depends on int $0x80 zeroing r8-r11,
      change the kernel to preserve them.
      
      I suspect that very little user code is broken by the old clobber, since
      r8-r11 are only rarely allocated by gcc, and they're clobbered by function
      calls, so they only way we'd see a problem is if the same function that
      invokes int $0x80 also spills something important to one of these
      registers.
      
      The current behavior seems to date back to the historical commit
      "[PATCH] x86-64 merge for 2.6.4".  Before that, all regs were
      preserved.  I can't find any explanation of why this change was made.
      
      Update the test_syscall_vdso_32 testcase as well to verify the new
      behavior, and it strengthens the test to make sure that the kernel doesn't
      accidentally permute r8..r15.

      x86/ipc: Fix x32 version of shmid64_ds and msqid64_ds · 1a512c08
      Arnd Bergmann authored
      A bugfix broke the x32 shmid64_ds and msqid64_ds data structure layout
      (as seen from user space)  a few years ago: Originally, __BITS_PER_LONG
      was defined as 64 on x32, so we did not have padding after the 64-bit
      __kernel_time_t fields, After __BITS_PER_LONG got changed to 32,
      applications would observe extra padding.
      
      In other parts of the uapi headers we seem to have a mix of those
      expecting either 32 or 64 on x32 applications, so we can't easily revert
      the path that broke these two structures.
      
      Instead, this patch decouples x32 from the other architectures and moves
      it back into arch specific headers, partially reverting the even older
      commit 73a2d096 ("x86: remove all now-duplicate header files").
      
      It's not clear whether this ever made any difference, since at least
      glibc carries its own (correct) copy of both of these header files,
      so possibly no application has ever observed the definitions here.
      
      Based on a suggestion from H.J. Lu, I tried out the tool from
      https://github.com/hjl-tools/linux-header to find other such
      bugs, which pointed out the same bug in statfs(), which also has
      a separate (correct) copy in glibc.

      x86/setup: Do not reserve a crash kernel region if booted on Xen PV · 3db3eb28
      Petr Tesarik authored
      Xen PV domains cannot shut down and start a crash kernel. Instead,
      the crashing kernel makes a SCHEDOP_shutdown hypercall with the
      reason code SHUTDOWN_crash, cf. xen_crash_shutdown() machine op in
      arch/x86/xen/enlighten_pv.c.
      
      A crash kernel reservation is merely a waste of RAM in this case. It
      may also confuse users of kexec_load(2) and/or kexec_file_load(2).
      When flags include KEXEC_ON_CRASH or KEXEC_FILE_ON_CRASH,
      respectively, these syscalls return success, which is technically
      correct, but the crash kexec image will never be actually used.

      i2c: dev: prevent ZERO_SIZE_PTR deref in i2cdev_ioctl_rdwr() · 23a27722
      Alexander Popov authored
      i2cdev_ioctl_rdwr() allocates i2c_msg.buf using memdup_user(), which
      returns ZERO_SIZE_PTR if i2c_msg.len is zero.
      
      Currently i2cdev_ioctl_rdwr() always dereferences the buf pointer in case
      of I2C_M_RD | I2C_M_RECV_LEN transfer. That causes a kernel oops in
      case of zero len.
      
      Let's check the len against zero before dereferencing buf pointer.

      arm64: avoid instrumenting atomic_ll_sc.o · 3789c122
      Mark Rutland authored
      Our out-of-line atomics are built with a special calling convention,
      preventing pointless stack spilling, and allowing us to patch call sites
      with ARMv8.1 atomic instructions.
      
      Instrumentation inserted by the compiler may result in calls to
      functions not following this special calling convention, resulting in
      registers being unexpectedly clobbered, and various problems resulting
      from this.
      
      For example, if a kernel is built with KCOV and ARM64_LSE_ATOMICS, the
      compiler inserts calls to __sanitizer_cov_trace_pc in the prologues of
      the atomic functions. This has been observed to result in spurious
      cmpxchg failures, leading to a hang early on in the boot process.
      
      This patch avoids such issues by preventing instrumentation of our
      out-of-line atomics.

      powerpc: Fix deadlock with multiple calls to smp_send_stop · 6029755e
      Nicholas Piggin authored
      smp_send_stop can lock up the IPI path for any subsequent calls,
      because the receiving CPUs spin in their handler function. This
      started becoming a problem with the addition of an smp_send_stop
      call in the reboot path, because panics can reboot after doing
      their own smp_send_stop.
      
      The NMI IPI variant was fixed with ac61c115 ("powerpc: Fix
      smp_send_stop NMI IPI handling"), which leaves the smp_call_function
      variant.
      
      This is fixed by having smp_send_stop only ever do the
      smp_call_function once. This is a bit less robust than the NMI IPI
      fix, because any other call to smp_call_function after smp_send_stop
      could deadlock, but that has always been the case, and it was not
      been a problem before.
