X-Git-Tag: v2.6.21-rc1~64^2~6 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=102fa15c3f14565f2edb9f08f08ea3f2bf123dc9;p=pandora-kernel.git [MIPS] Use MIPS R2 instructions for bitops. Add R2 optimized variants of clear_bit, set_bit and test_and_clear_bit. With gcc 4.1.1 this saves 1592 bytes on a defconfig (minus IPv6) kernel. Turns out that R2 bitop instructions are no gain for the other bitop functions. Signed-off-by: Ralf Baechle --- Reading git-diff-tree failed
