Subject: [PATCH 00/20 v4] staging: gasket: sundry fixes and fixups

From: Todd Poynor <toddpoynor@...gle.com>

Various fixes mainly from the chromium review of the gasket and apex
drivers.  More to come.

Todd Poynor (20):
  staging: gasket: allow compile for ARM64 in Kconfig
  staging: gasket: gasket_enable_dev remove unnecessary variable
  staging: gasket: remove code for no physical device
  staging: gasket: fix class create bug handling
  staging: gasket: remove unnecessary code in coherent allocator
  staging: gasket: don't treat no device reset callback as an error
  staging: gasket: gasket_mmap return error instead of valid BAR index
  staging: gasket: apex_clock_gating simplify logic, reduce indentation
  staging: gasket: gasket page table functions use bool return type
  staging: gasket: remove else clause after return in if clause
  staging: gasket: fix comment syntax in apex.h
  staging: gasket: remove unnecessary parens in page table code
  staging: gasket: gasket_mmap use PAGE_MASK
  staging: gasket: remove extra parens in gasket_write_mappable_regions
  staging: gasket: fix multi-line comment syntax in gasket_core.h
  staging: gasket: always allow root open for write
  staging: gasket: top ioctl handler add __user annotations
  staging: gasket: apex ioctl add __user annotations
  staging: gasket: common ioctl dispatcher add __user annotations
  staging: gasket: common ioctls add __user annotations

Patches changed from v3 in v4:
  staging: gasket: remove X86 Kconfig restriction
     Rename: staging: gasket: allow compile for ARM64 in Kconfig
     Restore existing "depends on" for X86_64, add ARM64.  Only compile for
     64-bit architectures known to work with this driver.
  staging: gasket: always allow root open for write
     Fold in patch to convert apex_ioctl_check_permissions to return bool
     Convert gasket_ioctl_check_permissions to use bool types.
  staging: gasket: apex_ioctl_check_permissions use bool return type
     Folded into above patch.
  staging: gasket: annotate ioctl arg with __user
     Split up into new patches:
        staging: gasket: top ioctl handler add __user annotations
	staging: gasket: apex ioctl add __user annotations
	staging: gasket: common ioctl dispatcher add __user annotations
	staging: gasket: common ioctls add __user annotations
     Convert various uses of void * to actual type.
     Minor formatting and naming changes.
     Drop Reviewed-By: Dmitry Torokhov due to changes since review.
