On x86_64 machines with more than 2 GB of RAM there are large memory gaps
(with no corresponding kernel virtual addresses) and reserved memory
regions between areas of usable physical RAM. Moreover, if CONFIG_FLATMEM
is set, they appear within the normal zone. swsusp should not try to save
them, so the corresponding page structs have to be marked as 'nosave'.Signed-off-by: Rafael J. Wysocki

I think it was only needed for the printks and we can do them later.
I put in a single early_printk so that we know the kernel is alive
(early_printk doesn't need any locks)This makes some things easier for initialization of unwind for
lockdep, which is needed by later patches.cc: mingo@elte.hu

Instead of hackish manual parsing
Requires earlier i386 patchkit, but also fixes i386 early_printk again.
I removed some obsolete really early parameters which didn't do anything useful.
Also made a few parameters that needed it early (mostly oops printing setup)Also removed one panic check that wasn't visible without
early console anyways (the early console is now initialized after that
panic)This cleans up a lot of code.

While an earlier patch already did a small step into that direction,
this patch moves initialization of all memory end variables to as
early as possible, so that dependent code doesn't need to check
whether these variables have already been set.Also, remove a misleading (perhaps just outdated) comment, and make
static a variable only used in a single file.Signed-off-by: Jan Beulich

Noticed by Jan Beulich.
When the kernel was moved from 1MB to 2MB in 2.6.17 the kernel reservation
code wasn't adjusted and it still reserved starting with 1MB. This means 1MB always
were lost.This patch fixes this by reserving only starting with _text.

screen_info.h doesn't have anything to do with the tty layer and shouldn't be
included by tty.h. This patches removes the include and modifies all users to
directly include screen_info.h. struct screen_info is mainly used to
communicate with the console drivers in drivers/video/console. Note that this
patch touches every arch and I have no way of testing it. If there is a
mistake the worst thing that will happen is a compile error.[akpm@osdl.org: fix arm build]

Intel now has support for Architectural Performance Monitoring Counters
( Refer to IA-32 Intel Architecture Software Developer's Manual
http://www.intel.com/design/pentium4/manuals/253669.htm ). This
feature is present starting from Intel Core Duo and Intel Core Solo processors.What this means is, the performance monitoring counters and some performance
monitoring events are now defined in an architectural way (using cpuid).
And there will be no need to check for family/model etc for these architectural
events.Below is the patch to use this performance counters in nmi watchdog driver.

This patch creates a new interface for IOMMUs by adding a centralized
location for IOMMU allocation (for translation tables/apertures) and
IOMMU initialization. In creating these, code was moved around for
abstraction, uniformity, and consiceness.Take note of the move of the iommu_setup bootarg parsing code to
__setup. This is enabled by moving back the location of the aperture
allocation/detection to mem init (which while ugly, was already the
location of the swiotlb_init).While a slight departure from the previous patch, I belive this provides
the true intention of the previous versions of the patch which changed
this code. It also makes the addition of the upcoming calgary code much
cleaner than previous patches.[AK: Removed one broken change. iommu_setup still has to be called

Changes are largely identical to the i386 version:
* alternative #define are moved to the new alternative.h file.
* one new elf section with pointers to the lock prefixes which can be
nop'ed out for non-smp.
* two new elf sections simliar to the "classic" alternatives to
replace SMP code with simpler UP code.
* fixup headers to use alternative.h instead of defining their own
LOCK / LOCK_PREFIX macros.The patch reuses the i386 version of the alternatives code to avoid code
duplication. The code in alternatives.c was shuffled around a bit to
reduce the number of #ifdefs needed. It also got some tweaks needed for
x86_64 (vsyscall page handling) and new features (noreplacement option
which was x86_64 only up to now). Debug printk's are changed from
compile-time to runtime.Loosely based on a early version from Bastian Blank

This patch will fix a boot memory reservation bug that trashes memory on
the ES7000 when loading the kdump crash kernel.The code in arch/x86_64/kernel/setup.c to reserve boot memory for the crash
kernel uses the non-numa aware "reserve_bootmem" function instead of the
NUMA aware "reserve_bootmem_generic". I checked to make sure that no other
function was using "reserve_bootmem" and found none, except the ones that
had NUMA ifdef'ed out.I have tested this patch only on an ES7000 with NUMA on and off (numa=off)
in a single (non-NUMA) and multi-cell (NUMA) configurations.Signed-off-by: Amul Shah
