global_lock is defined as an unsigned long and accessing only its lower 32 bits from sysfs is incorrect, as we need to consider other 32 bits for big endian 64 bit systems. Fix that by making global_lock an u32 instead. Cc: <stable@xxxxxxxxxxxxxxx> # v4.1+ Signed-off-by: Viresh Kumar <viresh.kumar@xxxxxxxxxx> --- Its marked just for # v4.1+, because arm64 has the first 64 big-endian platform with ACPI. And ACPI support for that is mainlined recently only (Arnd Bergmann).
Just to clarify, we don't support big-endian with ACPI on ARM64. We mandate use of EFI for ACPI on ARM64 and EFI spec mandates only little endian.
