Subject: sh: Fix up uncached offset for legacy 29-bit mode.
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=40d1f0048289b1baed859baee06878417fae540e;p=linux-beck.git

sh: Fix up uncached offset for legacy 29-bit mode.

The uncached_start was being set up properly for 32-bit but managed to
break 29-bit in the process, fix it up.
