Philipp Kohlbecher e1286f2c68 x86: documentation fix regarding boot protocol
Impact: clarify documentation

Documentation/x86/boot.txt describes payload_offset as the offset
from the end of the real-mode code. In fact, it is more accurately
described as the offset from the beginning of the protected-mode
code, as (a) this is how it is actually calculated and (b) the padding
after the real-mode code is not included in the offset.

Jiri Slaby a4c52791fa x86, 64-bit: update address space documentation
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.

Cyrill Gorcunov 5b9a0e14eb x86: nmi - nmi_watchdog boot param docs cleanup
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.

Luiz Fernando N. Capitulino 1befdefcf4 x86: remove 8254 timer texts from Documentation
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.

Paul Jackson 200001eb14 x86 boot: only pick up additional EFI memmap if add_efi_memmap flag
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.

H. Peter Anvin 23deb06821 x86: move x86-specific documentation into Documentation/x86
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.
