Pull ACPI fixes from Rafael Wysocki:
"These fix an ACPI initialization ordering issue introduced in the 4.17
time frame and causing functional problems to appear on multiple
systems and fix some fallout of the recent change to enable building
kernels with ACPI support and without PCI.
Specifics:
- Restore the ACPI initialization ordering changed implicitly by the
module-level AML handling rework during the 4.17 development cycle
that caused the EC address space handler based on information from
ECDT to be set up before loading AML definition blocks, making it
effectively not accessible by AML on some systems that don't work
as expected any more (Rafael Wysocki).
- Add direct dependencies on PCI to Kconfig in multiple places for
code that depends on both ACPI and PCI, but the PCI dependency was
implicitly satisfied by the ACPI dependency before, to prevent
invalid configurations from being created, for example by
randconfig (Sinan Kaya)"

There's a race between afs_make_call() and afs_wake_up_async_call() in the
case that an error is returned from rxrpc_kernel_send_data() after it has
queued the final packet.
afs_make_call() will try and clean up the mess, but the call state may have
been moved on thereby causing afs_process_async_call() to also try and to
delete the call.
Fix this by:
(1) Getting an extra ref for an asynchronous call for the call itself to
hold. This makes sure the call doesn't evaporate on us accidentally
and will allow the call to be retained by the caller in a future
patch. The ref is released on leaving afs_make_call() or
afs_wait_for_call_to_complete().
(2) In the event of an error from rxrpc_kernel_send_data():
(a) Don't set the call state to AFS_CALL_COMPLETE until *after* the
call has been aborted and ended. This prevents
afs_deliver_to_call() from doing anything with any notifications
it gets.
(b) Explicitly end the call immediately to prevent further callbacks.
(c) Cancel any queued async_work and wait for the work if it's
executing. This allows us to be sure the race won't recur when we
change the state. We put the work queue's ref on the call if we
managed to cancel it.
(d) Put the call's ref that we got in (1). This belongs to us as long
as the call is in state AFS_CALL_CL_REQUESTING.

A cb_interest record is not necessarily attached to the vnode on entry to
afs_validate(), which can cause an oops when we try to bring the vnode's
cb_s_break up to date in the default case (ie. no current callback promise
and the vnode has not been deleted).
Fix this by simply removing the line, as vnode->cb_s_break will be set when
needed by afs_register_server_cb_interest() when we next get a callback
promise from RPC call.
The oops looks something like:

Commit c3ff2a5193 ("powerpc/32: add stack protector support")
caused kernel panic on PowerPC when an external module is used with
CONFIG_STACKPROTECTOR because the 'prepare' target was not executed
for the external module build.
Commit e07db28eea ("kbuild: fix single target build for external
module") turned it into a build error because the 'prepare' target is
now executed but the 'prepare0' target is missing for the external
module build.
External module on arm/arm64 with CONFIG_STACKPROTECTOR_PER_TASK is
also broken in the same way.
Move 'PHONY += prepare0' to the common place. GNU Make is fine with
missing rule for phony targets. I also removed the comment which is
wrong irrespective of this commit.
I minimize the change so it can be easily backported to 4.20.x
To fix v4.20, please backport e07db28eea ("kbuild: fix single target
build for external module"), and then this commit.

Backlight is conceptually a property of links, not streams.
All backlight programming is done on links, but there is a
stream property bl_pwm_level that is used to restore backlight
on dpms on and s3 resume. This is unnecessary, as backlight
is already restored by hardware with no driver intervention.
[How]
Remove bl_pwm_level, and the stream argument to set_backlight

SELinux policy load"
* tag 'selinux-pr-20190115' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux:
selinux: fix GPF on invalid policy
Some systems have had functional issues since commit 5a8361f7ec
(ACPICA: Integrate package handling with module-level code) that,
among other things, changed the initial values of the
acpi_gbl_group_module_level_code and acpi_gbl_parse_table_as_term_list
global flags in ACPICA which implicitly caused acpi_ec_ecdt_probe() to
be called before acpi_load_tables() on the vast majority of platforms.
Namely, before commit 5a8361f7ec, acpi_load_tables() was called from
acpi_early_init() if acpi_gbl_parse_table_as_term_list was FALSE and
acpi_gbl_group_module_level_code was TRUE, which almost always was
the case as FALSE and TRUE were their initial values, respectively.
The acpi_gbl_parse_table_as_term_list value would be changed to TRUE
for a couple of platforms in acpi_quirks_dmi_table[], but it remained
FALSE in the vast majority of cases.
After commit 5a8361f7ec, the initial values of the two flags have
been reversed, so in effect acpi_load_tables() has not been called
from acpi_early_init() any more. That, in turn, affects
acpi_ec_ecdt_probe() which is invoked before acpi_load_tables() now
and it is not possible to evaluate the _REG method for the EC address
space handler installed by it. That effectively causes the EC address
space to be inaccessible to AML on platforms with an ECDT matching the
EC device definition in the DSDT and functional problems ensue in
there.
Because the default behavior before commit 5a8361f7ec was to call
acpi_ec_ecdt_probe() after acpi_load_tables(), it should be safe to
do that again. Moreover, the EC address space handler installed by
acpi_ec_ecdt_probe() is only needed for AML to be able to access the
EC address space and the only AML that can run during acpi_load_tables()
is module-level code which only is allowed to access address spaces
with default handlers (memory, I/O and PCI config space).
For this reason, move the acpi_ec_ecdt_probe() invocation back to
acpi_bus_init(), from where it was taken away by commit d737f333b2
(ACPI: probe ECDT before loading AML tables regardless of module-level
code flag), and put it after the invocation of acpi_load_tables() to
restore the original code ordering from before commit 5a8361f7ec.
