Subject: objtool: Remove workaround for unreachable warnings from old GCC
X-Git-Tag: v4.19~248^2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=113fc08357ad4e8b84caa75402430875d9ac4c1a;p=platform%2Fkernel%2Flinux-rpi3.git

objtool: Remove workaround for unreachable warnings from old GCC

Commit cafa0010cd51 ("Raise the minimum required gcc version to 4.6")
bumped the minimum GCC version to 4.6 for all architectures.

This effectively reverts commit da541b20021c ("objtool: Skip unreachable
warnings for GCC 4.4 and older"), which was a workaround for GCC 4.4 or
older.
