e1531b4218 [PATCH] ia64: re-implement dma_get_cache_alignment to avoid EXPORT_SYMBOL
The current ia64 implementation of dma_get_cache_alignment does not work
for modules because it relies on a symbol which is not exported.  Direct
access to a global is a little ugly anyway, so this patch re-implements
dma_get_cache_alignment in a manner similar to what is currently used for
x86_64.

ce6e71ad48 [IA64] fix siblings field value in /proc/cpuinfo
Fix the "siblings" field value in /proc/cpuinfo so that it now shows the
number of siblings as seen by OS, instead of what is available from
hardware perspective.

d719948e62 [IA64] end of kernel 'data' is at _end, not _edata
/proc/iomem describes a block of memory as "Kernel data",
but the end address is derived from "_edata".  The kernel
actually has many other sections beyond _edata.  Get the
real end address from _end.

44c451208d [IA64] ia64: add ar.k0 usage note
Update comment about how ar.k0 is used.  Make the initialization the
same as in start_secondary() (no functional change, just make it look
more similar).

be379124c0 [IA64] include EFI memory information in /proc/iomem
User mode kexec tools expect to find information about physical
memory in /proc/iomem (as they do on x86) to validate the addresses
that the new kernel will use.

d8c97d5f3a [IA64] simplified efi memory map parsing
New version leaves the original memory map unmodified.
Also saves any granule trimmings for use by the uncached
memory allocator.

Inspired by Khalid Aziz (various traces of his patch still
remain).  Fixes to uncached_build_memmap() and sn2 testing
by Martin Hicks.

66b7f8a304 [IA64-SGI] pcdp: add PCDP pci interface support
Resend 2 with changes per Bjorn Helgaas comments.  Changes from original:

+ Change globals to vga_console_iobase/vga_console_membase and make them
  unconditional.
+ Address style-related comments.

Patch to extend the PCDP vga setup code to support PCI io/mem translations
for the legacy vga ioport and ram spaces on architectures (e.g. altix) which
need them.

Summary of the changes:

drivers/firmware/pcdp.c
drivers/firmware/pcdp.h
-----------------------
+ add declaration for the spec-defined PCI interface struct (pcdp_if_pci)
  as well as support macros.

+ extend setup_vga_console() to know about pcdp_if_pci and add a couple of
  globals to hold the io and mem translation offsets if present.

arch/ia64/kernel/setup.c
------------------------
+ tweek early_console_setup() to allow multiple early console setup routines
  to be called.

include/asm-ia64/vga.h
----------------------
+ make VGA_MAP_MEM vga_console_membase aware

e927ecb05e [IA64] multi-core/multi-thread identification
Version 3 - rediffed to apply on top of Ashok's hotplug cpu
patch.  /proc/cpuinfo output in step with x86.

This is an updated MC/MT identification patch based on the 
previous discussions on list. 

Add the Multi-core and Multi-threading detection for IPF.
  - Add new core and threading related fields in /proc/cpuinfo.
		Physical id
		Core id
		Thread id
		Siblings
  - setup the cpu_core_map and cpu_sibling_map appropriately
  - Handles Hot plug CPU

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!
