      x86: export pv_lock_ops non-GPL · 25258ef7
      由 Jeremy Fitzhardinge 提交于 
      None of the spinlock API is exported GPL, so there's no reason for
pv_lock_ops to be.

      x86: work around MTRR mask setting, v2 · 9754a5b8
      由 Ingo Molnar 提交于 
      improve the debug printout:

- make it actually display something
- print it only once

would be nice to have a WARN_ONCE() facility, to feed such things to
kerneloops.org.

      x86: fix section mismatch warning - uv_cpu_init · c4bd1fda
      由 Marcin Slusarz 提交于 
      WARNING: vmlinux.o(.cpuinit.text+0x3cc4): Section mismatch in reference from the function uv_cpu_init() to the function .init.text:uv_system_init()
The function __cpuinit uv_cpu_init() references
a function __init uv_system_init().
If uv_system_init is only used by uv_cpu_init then
annotate uv_system_init with a matching annotation.

uv_system_init was ment to be called only once, so do it from codepath
(native_smp_prepare_cpus) which is called once, right before activation
of other cpus (smp_init).

Note: old code relied on uv_node_to_blade being initialized to 0,
but it'a not initialized from anywhere.

      x86: fix VMI for early params · 3a6ddd5f
      由 Alok Kataria 提交于 
      while fixing a different bug i moved the call to vmi_init before
early params could be parsed.

This broke the vmi specific commandline parameters.
Fix that, by moving vmi initialization after kernel has got a chance to
parse early parameters.

      x86: work around MTRR mask setting · 38cc1c3d
      由 Yinghai Lu 提交于 
      Joshua Hoblitt reported that only 3 GB of his 16 GB of RAM is
usable. Booting with mtrr_show showed us the BIOS-initialized
MTRR settings - which are all wrong.

So the root cause is that the BIOS has not set the mask correctly:

      x86: fix i486 suspend to disk CR4 oops · e532c06f
      由 David Fries 提交于 
      arch/x86/power/cpu_32.c __save_processor_state calls read_cr4()
only a i486 CPU doesn't have the CR4 register.  Trying to read it
produces an invalid opcode oops during suspend to disk.

Use the safe rc4 reading op instead. If the value to be written is
zero the write is skipped.

arch/x86/power/hibernate_asm_32.S
done: swapped the use of %eax and %ecx to use jecxz for
the zero test and jump over store to %cr4.
restore_image: s/%ecx/%eax/ to be consistent with done:

In addition to __save_processor_state, acpi_save_state_mem,
efi_call_phys_prelog, and efi_call_phys_epilog had checks added
(acpi restore was in assembly and already had a check for
non-zero).  There were other reads and writes of CR4, but MCE and
virtualization shouldn't be executed on a i486 anyway.
