Subject: arm64: move DBG_MDSCR_* to asm/debug-monitors.h
X-Git-Tag: firefly_0821_release~3680^2~36^2~16^2^2~70
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=efacbc423cf057a9051ca0fd240e68f5596700e7;p=firefly-linux-kernel-4.4.55.git

arm64: move DBG_MDSCR_* to asm/debug-monitors.h

In order to be able to use the DBG_MDSCR_* macros from the KVM code,
move the relevant definitions to the obvious include file.

Also move the debug_el enum to a portion of the file that is guarded
by #ifndef __ASSEMBLY__ in order to use that file from assembly code.
