888a589f6b mm, x86: remove MEMORY_HOTPLUG_RESERVE related code

 |    x86: 64-bit, make sparsemem vmemmap the only memory model

we don't have MEMORY_HOTPLUG_RESERVE anymore.

Historically, x86-64 had an architecture-specific method for memory hotplug
whereby it scanned the SRAT for physical memory ranges that could be
potentially used for memory hot-add later. By reserving those ranges
without physical memory, the memmap would be allocated and left dormant
until needed. This depended on the DISCONTIG memory model which has been
removed so the code implementing HOTPLUG_RESERVE is now dead.

This patch removes the dead code used by MEMORY_HOTPLUG_RESERVE.

(Changelog authored by Mel.)

v2: updated changelog, and remove hotadd= in doc

[ Impact: remove dead code ]

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.

71cced6eb0 doc/x86: fix doc subdirs
The Documentation/i386 and Documentation/x86_64 directories and their
contents have been moved into Documentation/x86. Fix references to
those files accordingly.

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.

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.
