Subject: x86: entry_32.S - use flags from processor-flags.h
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=ab68ed98f665436601feec853c8f400d28c39e92;p=openwrt%2Fstaging%2Fblogic.git

x86: entry_32.S - use flags from processor-flags.h

By including processor-flags.h we are allowed to use predefined
macroses instead of keeping own ones
