# PowerPC: Fix gettimeofday ifunc selection
#
# The IFUNC selector for gettimeofday runs before _libc_vdso_platform_setup where
# __vdso_gettimeofday is set. The selector then sets __gettimeofday (the internal
# version used within GLIBC) to use the system call version instead of the vDSO one.
# This patch changes the check if vDSO is available to get its value directly
# instead of rely on __vdso_gettimeofday.
#
# This patch changes it by getting the vDSO value directly.
#
# It fixes BZ#16431.
