Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/cmarinas/linux-aarch64
Pull arm64 fixes from Catalin Marinas:
"Fixes for duplicate definition of early_console, kernel/time/Kconfig
include, __flush_dcache_all() set/way computing, debug (locking, bit
testing). The of_platform_populate() was moved to an arch_init_call()
to allow subsys_init_call() drivers to probe the DT."
* tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/cmarinas/linux-aarch64:
arm64: debug: fix mdscr.ss check when enabling debug exceptions
arm64: Do not source kernel/time/Kconfig explicitly
arm64: mm: Fix operands of clz in __flush_dcache_all
arm64: Invoke the of_platform_populate() at arch_initcall() level
arm64: debug: clear mdscr_el1 instead of taking the OS lock
arm64: Fix duplicate definition of early_console
