Subject: s390/fault: use _ASCE_ORIGIN instead of PAGE_MASK
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=fe7b274729fc0bab9b4238f875695d36726a6b10;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

s390/fault: use _ASCE_ORIGIN instead of PAGE_MASK

When masking an ASCE to get its origin use the corresponding define
instead of the unrelated PAGE_MASK.
This doesn't fix a bug since both masks are identical.
