      mm, x86: remove MEMORY_HOTPLUG_RESERVE related code · 888a589f
      由 Yinghai Lu 提交于 
      after:

 | commit b263295d
 | Author: Christoph Lameter <clameter@sgi.com>
 | Date:   Wed Jan 30 13:30:47 2008 +0100
 |
 |    x86: 64-bit, make sparsemem vmemmap the only memory model

we don't have MEMORY_HOTPLUG_RESERVE anymore.

Historically, x86-64 had an architecture-specific method for memory hotplug
whereby it scanned the SRAT for physical memory ranges that could be
potentially used for memory hot-add later. By reserving those ranges
without physical memory, the memmap would be allocated and left dormant
until needed. This depended on the DISCONTIG memory model which has been
removed so the code implementing HOTPLUG_RESERVE is now dead.

This patch removes the dead code used by MEMORY_HOTPLUG_RESERVE.

(Changelog authored by Mel.)

v2: updated changelog, and remove hotadd= in doc

      x86: check boundary in setup_node_bootmem() · 4c31e92b
      由 Yinghai Lu 提交于 
      Commit dc098551 ("x86/uv: fix init of memory-less nodes") causes a
two sockets system (where node-1 doesn't have RAM installed) to crash.

That commit makes node_possible include cpu nodes that do not have memory.
So check boundary in setup_node_bootmem().

      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/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: fix wrong section of pat_disable & make it static · 1ee4bd92
      由 Marcin Slusarz 提交于 
      pat_disable cannot be __cpuinit anymore because it's called from pat_init
and the callchain looks like this:
pat_disable [cpuinit] <- pat_init <- generic_set_all <-
 ipi_handler <- set_mtrr <- (other non init/cpuinit functions)

WARNING: arch/x86/mm/built-in.o(.text+0x449e): Section mismatch in reference
from the function pat_init() to the function .cpuinit.text:pat_disable()
The function pat_init() references
the function __cpuinit pat_disable().
This is often because pat_init lacks a __cpuinit
annotation or the annotation of pat_disable is wrong.

Non CONFIG_X86_PAT version of pat_disable is static inline, so this version
can be static too (and there are no callers outside of this file).
