Subject: Avoid tlb_set_page in userspace emulation
X-Git-Tag: TizenStudio_2.0_p2.3.2~208^2~8583
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=c527ee8fc8550f49fb94890bc88dcdf011c0b4eb;p=sdk%2Femulator%2Fqemu.git

Avoid tlb_set_page in userspace emulation

tlb_set_page isn't meaningful for userspace emulation, so remove it.
