Subject: x86: put movsl_mask into uaccess.h.
X-Git-Tag: v2.6.27-rc1~1106^2~46^2~1
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8bc7de0c5dc0a5d3bcdc04bac6de0c799f91c5e4;p=linux-2.6

x86: put movsl_mask into uaccess.h.

x86_64 does not need it, but it won't have X86_INTEL_USERCOPY
defined either.
