Subject: x86, setup: move 32-bit code to .text32
X-Git-Tag: 2.1b_release~12498^2~28^3~1
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=be721696cac9d66566d59b205ee573ecb2f7c35b;p=platform%2Fkernel%2Fkernel-mfld-blackbay.git

x86, setup: move 32-bit code to .text32

Impact: cleanup

The setup code is mostly 16-bit code, but there is a small stub of
32-bit code at the end.  Move the 32-bit code to a separate segment,
.text32, to avoid scrambling the disassembly.
