b92e9fac40 [PATCH] x86: fix amd64-agp aperture validation
Under CONFIG_DISCONTIGMEM, assuming that a !pfn_valid() implies all
subsequent pfn-s are also invalid is wrong. Thus replace this by
explicitly checking against the E820 map.

AK: make e820 on x86-64 not initdata

0adad171c2 [PATCH] i386: probe_roms() cleanup
Remove the assumption that if the first page of a legacy ROM is mapped,
it'll all be mapped. This'll also stop people reading this code from
wondering if they're looking at a bug...

3b3d5e1db6 [PATCH] i386: romsignature/checksum cleanup
Use adding __init to romsignature() (it's only called from probe_roms()
which is itself __init) as an excuse to submit a pedantic cleanup.

5c95da9f5a [PATCH] compile error of register_memory()
register_memory() becomes double definition in 2.6.20-rc1.  It is defined
in arch/i386/kernel/setup.c as static definition in 2.6.19.  But it is
moved to arch/i386/kernel/e820.c in 2.6.20-rc1.  And same name function is
defined in driver/base/memory.c too.  So, it becomes cause of compile error
of duplicate definition if memory hotplug option is on.

bf7e6a1963 [PATCH] i386: Preserve EFI run time regions with memmap parameter
When using memmap kernel parameter in EFI boot we should also add to memory map
memory regions of runtime services to enable their mapping later.

AK: merged and cleaned up the patch

bd472c794b [PATCH] paravirt: Be careful about touching BIOS address space
BIOS ROM areas may not be mapped into the guest address space, so be careful
when touching those addresses to make sure they appear to be mapped.
