g analogous to bit 2 in ACPI's _STA object return value
(i.e., "show in UI").
A full listing of all fw_cfg items can still be made available
by enabling the 'list_all' module parameter, also introduced by
this patch.

Changes since v1:
- no more "#ifdef CONFIG_ACPI"; instead we proceed if
acpi_acquire_global_lock() returns either OK or NOT_CONFIGURED,
and only throw a warning/error message otherwise.
- didn't get any *negative

Turns out, there *is* a way to acquire a global ACPI lock from within
a "random" kernel driver after all. Luckily I have a healthy dose of
respect for Michael's opinions :) so I kept circling back through
existing kernel sources for an example I can u
register offsets in drivers/firmware/qemu_fw_cfg.c at that
time.

With this, I can confirm everything still works fine on both Mavericks and
F21-beta-live. So:
