72538d8565 Remove "noreplacement" kernel command line option.
It is no longer valid to not replace instructions, since we depend on
different behaviour depending on CPU capabilities.

If you need to limit the capabilities of the replacements (because the
boot CPU has features that non-boot CPU's do not have, for example), you
need to explicitly disable those capabilities that are not shared across
all CPU's.

For example, if your boot CPU has FXSR, but other CPU's in your system
do not, you need to use the "nofxsr" kernel command line, not disable
instruction replacement per se.

92aa63a5a1 [PATCH] kdump: Retrieve saved max pfn
This patch retrieves the max_pfn being used by previous kernel and stores it
in a safe location (saved_max_pfn) before it is overwritten due to user
defined memory map.  This pfn is used to make sure that user does not try to
read the physical memory beyond saved_max_pfn.

1bc3b91aee [PATCH] crashdump: x86 crashkernel option
This is the x86 implementation of the crashkernel option.  It reserves a
window of memory very early in the bootup process, so we never use it for
anything but the kernel to switch to when the running kernel panics.

In addition to reserving this memory a resource structure is registered so
looking at /proc/iomem it is clear what happened to that memory.

ISSUES:
Is it possible to implement this in a architecture generic way?
What should be done with architectures that always use an iommu and
thus don't report their RAM memory resources in /proc/iomem?

8a9190853c [PATCH] kexec: reserve Bootmem fix for booting nondefault location kernel
This patch fixes a problem with reserving memory during boot up of a kernel
built for non-default location.  Currently boot memory allocator reserves
the memory required by kernel image, boot allocaotor bitmap etc.  It
assumes that kernel is loaded at 1MB (HIGH_MEMORY hard coded to 1024*1024).
 But kernel can be built for non-default locatoin, hence existing
hardcoding will lead to reserving unnecessary memory.  This patch fixes it.

9635b47d91 [PATCH] kexec: x86: local apic fix
From: "Maciej W. Rozycki" <macro@linux-mips.org>

Fix a kexec problem whcih causes local APIC detection failure.

The problem is detect_init_APIC() is called early, before the command line
have been processed.  Therefore "lapic" (and "nolapic") have not been seen,
yet.

129f69465b [PATCH] Remove i386_ksyms.c, almost.
* EXPORT_SYMBOL's moved to other files
* #include <linux/config.h>, <linux/module.h> where needed
* #include's in i386_ksyms.c cleaned up
* After copy-paste, redundant due to Makefiles rules preprocessor directives
  removed:

	#ifdef CONFIG_FOO
	EXPORT_SYMBOL(foo);
	#endif

	obj-$(CONFIG_FOO) += foo.o

* Tiny reformat to fit in 80 columns

adaa765d76 [PATCH] acpi build fix: x86 setup.c
This is a neverending story

linux/acpi.h contains empty declarations for acpi_boot_init() &
acpi_boot_table_init() but they are nested inside #ifdef CONFIG_ACPI.

So we'll have to #ifdef in arch/i386/kernel/setup.c: setup_arch()

1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
