Extend the maximum addressable memory on x86-64 from 2^44 to
2^46 bytes. This requires some shuffling around of the vmalloc
and virtual memmap memory areas, to keep them away from the
direct mapping of up to 64TB of physical memory.
This patch also introduces a guard hole between the vmalloc
area and the virtual memory map space. There's really no
good reason why we wouldn't have a guard hole there.

cgroup documentation was moved to Documentation/cgroups/. There are some
places that still refer to Documentation/controllers/,
Documentation/cgroups.txt and Documentation/cpusets.txt. Fix those.

Impact: documentation update
Commit a6523748bd
(paravirt/x86, 64-bit: move __PAGE_OFFSET to leave a space for hypervisor)
changed address space without changing the documentation.
Change it according to the code change -- direct mapping start:
ffff810000000000 => ffff880000000000 which gives 57 TiB, something
between 45 and 46 bits.

Impact: documentation update
1) nmi_watchdog boot parameter is common to 32/64 bit modes. So
move it from Documentation/x86/x86_64/boot-options.txt to
Documentation/kernel-parameters.txt and integrate with.
2) Also fix [panic] keyword placement -- it ought to be at first
position otherwise it will not be recognized.
3) Document lapic and ioapic keywords.

The Documentation/i386 and Documentation/x86_64 directories and their
contents have been moved into Documentation/x86. Fix references to
those files accordingly.

Commit ecd29476ae removed the
"disable_8254_timer" and "enable_8254_timer" kernel parameters from
the kernel but did not remove the references to them from two
files in the Documentation directory: kernel-parameters.txt and
x86/x86_64/boot-options.txt.
This change completes the removal.

Applies on top of the previous patch:
x86 boot: add code to add BIOS provided EFI memory entries to kernel
Instead of always adding EFI memory map entries (if present) to the
memory map after initially finding either E820 BIOS memory map entries
and/or kernel command line memmap entries, -instead- only add such
additional EFI memory map entries if the kernel boot option:
add_efi_memmap
is specified.
Requiring this 'add_efi_memmap' option is backward compatible with
kernels that didn't load such additional EFI memory map entries in
the first place, and it doesn't override a configuration that tries
to replace all E820 or EFI BIOS memory map entries with ones given
entirely on the kernel command line.

The current organization of the x86 documentation makes it appear as
if the "i386" documentation doesn't apply to x86-64, which is does.
Thus, move that documentation into Documentation/x86, and move the
x86-64-specific stuff into Documentation/x86/x86_64 with the eventual
goal to move stuff that isn't actually 64-bit specific back into
Documentation/x86.
