Subject: drm/amdkfd: Sign-extend TMA address in trap handler
X-Git-Tag: v6.6.17~3937^2~9^2~152
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=05c899eacc0412bae0581add19c4062db8bdffda;p=platform%2Fkernel%2Flinux-rpi.git

drm/amdkfd: Sign-extend TMA address in trap handler

SMEM instructions can reach addresses above 47 bits but require
bit 47 to be sign-extended through bits [63:48].

This allows the TMA to be relocated in a following patch.
