Subject: xtensa: initialize CPENABLE SR when core has one
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=eab5e7a79d1bb3d607dabf022bfad9f46d1e3ac8;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

xtensa: initialize CPENABLE SR when core has one

XCHAL_CP_NUM is defined in variant/tie.h and it is not included by
head.S, leaving CPENABLE register uninitialised. XCHAL_HAVE_CP is
defined in variant/core.h to 1 when core has CPENABLE SR.
