Together with the runtime custom method mechanism,
we can debug AML code problems without rebuilding the kernel.

This patch adds debugging/testing support to ERST. A misc device is
implemented to export raw ERST read/write/clear etc operations to user

linuxfirmwarekit ISO (linuxfirmwarekit.org) to verify the kernel
support and the firmware implementation.

 rwsem: wake queued readers when writer blocks on active read lock

made this change:

-           (rwsem_atomic_update(0, sem) & RWSEM_ACTIVE_MASK))
-               /* Someone grabbed the sem already */
+           rwsem_atomic_update(0, sem) < RWSEM_WAITING_BIAS)
+               /* Someone grabbed the sem for write already */

RWSEM_ACTIVE_MASK is 0xffffffffL, so the old code only looked
at the low order 32-bits. The new code needs to see all 64 bits.
