Bug Description

glibc-2.17 has a performance regression, which causes one of my workloads to spend a significant amount of cpu time in feraiseexcept. this regression has already been fixed in glibc's git repository (http://repo.or.cz/w/glibc.git/commit/0b57daeb) and it would be great, if this fix could be backported.

---------------
eglibc (2.17-0ubuntu5) raring; urgency=low

  * debian/debhelper.in/libc.postint: Switch from 'awk gsub' to 'tr -d' to
    avoid warnings when the awk alternative points to gawk (LP: #1156923)
  * debian/patches/any/submitted-setfsid-wur.diff: Drop __wur from setfsuid
    and setfsgid functions to avoid -Werror=unused-result (Closes: #701422)
  * debian/patches/i386/cvs-simd-exception.diff: Pull patch from upstream
    to fix a performance regression in i386 SIMD exceptions (LP: #1157244)
  * debian/patches/svn-updates.diff: Update to r22884 of eglibc-2_17 branch
  * debian/testsuite-checking/compare.sh: Disable hard testsuite failures
    for release to avoid stable updates exploding as buildd kernels change
