[GIT PULL] ACPI fixes for v4.7-rc7

[Rafael J. Wysocki]

Hi Linus,

Please pull from

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 acpi-4.7-rc7

to receive ACPI fixes for v4.7-rc7 with top-most commit
b6d90158c935d4a22e56f41647b479ab5ea449d4

 Merge branches 'acpica-fixes', 'acpi-pci-fixes' and 'acpi-debug-fixes'

on top of commit a99cde438de0c4c0cecc1d1af1a55a75b10bfdef

 Linux 4.7-rc6

All of these fix recent regressions in ACPICA, in the ACPI PCI IRQ
management code and in the ACPI AML debugger.

Specifics:

 - Fix a lock ordering issue in ACPICA introduced by a recent commit
   that attempted to fix a deadlock in the dynamic table loading code
   which in turn appeared after changes related to the handling of
   module-level AML also made in this cycle (Lv Zheng).

 - Fix a recent regression in the ACPI IRQ management code that may
   cause PCI drivers to be unable to register an IRQ if that IRQ
   happens to be shared with a device on the ISA bus, like the
   parallel port, by reverting one commit entirely and restoring the
   previous behavior in two other places (Sinan Kaya).

 - Fix a recent regression in the ACPI AML debugger introduced by
   the commit that removed incorrect usage of IS_ERR_VALUE() from
   multiple places (Lv Zheng).

Thanks!

FYI, it seems these changes lead to a new regression. Quoting

I wrote a comment on that, to see if the git issue that kept things
from bisecting into the merge can be worked around. That's a very
surprising error (but it's also not an exact quote of the error, so
who knows..)

Can you attach the boot log to the bugzilla?

Unfortunately, this code turned out to be the most fragile code. I fixed 
one issue and it looks like it broke yours.
