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.

This is odd and maybe confusing. With this patch, writing 'a' to
devices.allow will add 'a *:* rwm' to the whitelist.
Also a few fixes and updates to the document.

To stop "sync_action" from occasionally showing the wrong value,

that we set MD_RECOVERY_RUNNING before clearing MD_RECOVERY_NEEDED.

The current naming of rfkill_state causes a lot of confusion: not only the
"kill" in rfkill suggests negative logic, but also the fact that rfkill cannot
turn anything on (it can just force something off or stop forcing something
off) is often forgotten.
Rename RFKILL_STATE_OFF to RFKILL_STATE_SOFT_BLOCKED (transmitter is blocked
and will not operate; state can be changed by a toggle_radio request), and
RFKILL_STATE_ON to RFKILL_STATE_UNBLOCKED (transmitter is not blocked, and may
operate).
Also, add a new third state, RFKILL_STATE_HARD_BLOCKED (transmitter is blocked
and will not operate; state cannot be changed through a toggle_radio request),
which is used by drivers to indicate a wireless transmiter was blocked by a
hardware rfkill line that accepts no overrides.
Keep the old names as #defines, but document them as deprecated. This way,
drivers can be converted to the new names *and* verified to actually use rfkill
correctly one by one.

Rework the documentation so as to make sure driver writers understand
exactly where the boundaries are for input drivers related to rfkill
switches, buttons and keys, and rfkill class drivers.
Also fix a small error in the documentation: setting the state of a normal
instance of the rfkill class does not affect the state of any other devices
(unless they are tied by firmware/hardware somehow).
