      docs, x86: add nox2apic back to kernel-parameters.txt · 8b5b94e4
      由 Weidong Han 提交于 
      "nox2apic" was removed from kernel-parameters.txt by mistake, when
entries were sorted in alpha order (commit 0cb55ad2). But this early
parameter is still there, add it back to kernel-parameters.txt.

      x86: mm/numa_32.c calculate_numa_remap_pages should use __init · a81b6314
      由 Jaswinder Singh Rajput 提交于 
      calculate_numa_remap_pages() is called only by __init initmem_init()
further calculate_numa_remap_pages is calling:
	__init find_e820_area() and __init reserve_early()

So calculate_numa_remap_pages() should be __init calculate_numa_remap_pages().

 WARNING: arch/x86/built-in.o(.text+0x82ea3): Section mismatch in reference from the function calculate_numa_remap_pages() to the function .init.text:find_e820_area()
 The function calculate_numa_remap_pages() references
 the function __init find_e820_area().
 This is often because calculate_numa_remap_pages lacks a __init
 annotation or the annotation of find_e820_area is wrong.

 WARNING: arch/x86/built-in.o(.text+0x82f5f): Section mismatch in reference from the function calculate_numa_remap_pages() to the function .init.text:reserve_early()
 The function calculate_numa_remap_pages() references
 the function __init reserve_early().
 This is often because calculate_numa_remap_pages lacks a __init
 annotation or the annotation of reserve_early is wrong.

      x86, kbuild: make "make install" not depend on vmlinux · 1648e4f8
      由 H. Peter Anvin 提交于 
      It is common to use "make install" in restricted environments which
differ from the one which was actually used to build the kernel.  In
such environments it is highly undesirable to trigger a rebuild of any
part of the system.  Worse, the rebuild may be spurious, triggered by
differences in the environment.

      x86/uv: fix init of cpu-less nodes · 27229ca6
      由 Jack Steiner 提交于 
      Fix an endcase in the UV initialization code for the "UV large system mode"
of apicids.  If node zero contains no cpus, cpus on another node will be the
boot cpu.  The percpu data that contains the extra apicid bits was not
being initialized early enough.

      x86/uv: fix init of memory-less nodes · dc098551
      由 Jack Steiner 提交于 
      Add support for nodes that have cpus but no memory.
The current code was failing to add these nodes
to the nodes_present_map.

v2: Fixes case caught by David Rientjes - missed support
    for the x2apic SRAT table.

      x86: disable X86_PTRACE_BTS for now · d45b41ae
      由 Ingo Molnar 提交于 
      Oleg Nesterov found a couple of races in the ptrace-bts code
and fixes are queued up for it but they did not get ready in time
for the merge window. We'll merge them in v2.6.31 - until then
mark the feature as CONFIG_BROKEN. There's no user-space yet
making use of this so it's not a big issue.
