       "A couple of fixlets for x86:
      
         - Fix the ESPFIX double fault handling for 5-level pagetables
      
         - Fix the commandline parsing for 'apic=' on 32bit systems and update
           documentation
      
         - Make zombie stack traces reliable
      
         - Fix kexec with stack canary
      
         - Fix the delivery mode for APICs which was missed when the x86
           vector management was converted to single target delivery. Caused a
           regression due to the broken hardware which ignores affinity
           settings in lowest prio delivery mode.
      
         - Unbreak modules when AMD memory encryption is enabled
      
         - Remove an unused parameter of prepare_switch_to"

      Pull irq fixes from Thomas Gleixner:
       "A rather large update after the kaisered maintainer finally found time
        to handle regression reports.
      
         - The larger part addresses a regression caused by the x86 vector
           management rework.
      
           The reservation based model does not work reliably for MSI
           interrupts, if they cannot be masked (yes, yet another hw
           engineering trainwreck). The reason is that the reservation mode
           assigns a dummy vector when the interrupt is allocated and switches
           to a real vector when the interrupt is requested.
      
           If the MSI entry cannot be masked then the initialization might
           raise an interrupt before the interrupt is requested, which ends up
           as spurious interrupt and causes device malfunction and worse. The
           fix is to exclude MSI interrupts which do not support masking from
           reservation mode and assign a real vector right away.
      
         - Extend the extra lockdep class setup for nested interrupts with a
           class for the recently added irq_desc::request_mutex so lockdep can
           differeniate and does not emit false positive warnings.
      
         - A ratelimit guard for the bad irq printout so in case a bad irq
           comes back immediately the system does not drown in dmesg spam"

      x86/ldt: Plug memory leak in error path · a62d6985
      Thomas Gleixner authored
      The error path in write_ldt() tries to free 'old_ldt' instead of the newly
      allocated 'new_ldt', resulting in a memory leak. It also misses to clean up a
      half populated LDT pagetable, which is not a leak as it gets cleaned up
      when the process exits.
      
      Free both the potentially half populated LDT pagetable and the newly
      allocated LDT struct. This can be done unconditionally because once an LDT
      is mapped subsequent maps will succeed, because the PTE page is already
      populated and the two LDTs fit into that single page.

      x86/mm: Remove preempt_disable/enable() from __native_flush_tlb() · decab088
      Thomas Gleixner authored
      The preempt_disable/enable() pair in __native_flush_tlb() was added in
      commit:
      
        5cf0791d ("x86/mm: Disable preemption during CR3 read+write")
      
      ... to protect the UP variant of flush_tlb_mm_range().
      
      That preempt_disable/enable() pair should have been added to the UP variant
      of flush_tlb_mm_range() instead.
      
      The UP variant was removed with commit:
      
        ce4a4e56 ("x86/mm: Remove the UP asm/tlbflush.h code, always use the (formerly) SMP code")
      
      ... but the preempt_disable/enable() pair stayed around.
      
      The latest change to __native_flush_tlb() in commit:
      
        6fd166aa ("x86/mm: Use/Fix PCID to optimize user/kernel switches")
      
      ... added an access to a per CPU variable outside the preempt disabled
      regions, which makes no sense at all. __native_flush_tlb() must always
      be called with at least preemption disabled.
      
      Remove the preempt_disable/enable() pair and add a WARN_ON_ONCE() to catch
      bad callers independent of the smp_processor_id() debugging.

      x86/smpboot: Remove stale TLB flush invocations · 322f8b8b
      Thomas Gleixner authored
      smpboot_setup_warm_reset_vector() and smpboot_restore_warm_reset_vector()
      invoke local_flush_tlb() for no obvious reason.
      
      Digging in history revealed that the original code in the 2.1 era added
      those because the code manipulated a swapper_pg_dir pagetable entry. The
      pagetable manipulation was removed long ago in the 2.3 timeframe, but the
      TLB flush invocations stayed around forever.
      
      Remove them along with the pointless pr_debug()s which come from the same 2.1
      change.
