[Resending because of the messed-up subject, sorry.]

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 acpi-5.7-rc1

with top-most commit 1da28f032305383a664e5711ba07b7957901a72e

 Merge branches 'acpi-ec', 'acpi-fan' and 'acpi-pci'

on top of commit 2c523b344dfa65a3738e7039832044aa133c75fb

 Linux 5.6-rc5

to receive ACPI updates for 5.7-rc1.

These update the ACPICA code in the kernel to the 20200214 upstream
release, clean up the initialization of the EC driver, clean up the
quirk tables in the AC and battery drivers, fix the global lock
handling on x86, add a new "tiny" driver for ACPI button devices
exposed by VMs to guest kernels, modify the ACPI PCI host bridge and
fan drivers use scnprintf(), add add a kernel parameter to disable
ACPI BGRT on x86 and do some assorted cleanups.

Specifics:

 - Update the ACPICA code in the kernel to the 20200214 upstream
   release including:

   * Fix to re-enable the sleep button after wakeup (Anchal Agarwal).
   * Fixes for mistakes in comments and typos (Bob Moore).
   * ASL-ASL+ converter updates (Erik Kaneda).
   * Type casting cleanups (Sven Barth).

 - Clean up the intialization of the EC driver and eliminate some
   dead code from it (Rafael Wysocki).

 - Clean up the quirk tables in the AC and battery drivers (Hans de
   Goede).

 - Fix the global lock handling on x86 to ignore unspecified bit
   positions in the global lock field (Jan Engelhardt).

 - Add a new "tiny" driver for ACPI button devices exposed by VMs to
   guest kernels to send signals directly to init (Josh Triplett).

 - Add a kernel parameter to disable ACPI BGRT on x86 (Alex Hung).

 - Make the ACPI PCI host bridge and fan drivers use scnprintf() to
   avoid potential buffer overflows (Takashi Iwai).

 - Clean up assorted pieces of code:

   * Reorder "asmlinkage" to make g++ happy (Alexey Dobriyan).
   * Drop unneeded variable initialization (Colin Ian King).
   * Add missing __acquires/__releases annotations (Jules Irenge).
   * Replace list_for_each_safe() with list_for_each_entry_safe()
     (chenqiwu).

Thanks!
