Subject: (CTR/3DS) some performance tweaks:
X-Git-Tag: r24l~868
X-Git-Url: https://notaz.gp2x.de/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0b7f536b486f3f411651573009c3da6063b560ea;p=pcsx_rearmed.git

(CTR/3DS) some performance tweaks:
- use linearAlloc for vout_buf.
- use svcFlushProcessDataCache to flush only the required range,
invalidating icache doesn't seem to be required.
