2010-02-20sparc: Fix v9 memchr with long buffer lengths.David S. Miller
test-memchr fails on 32-bit sparc with v9 optimized memchr because it uses signed branch comparisons on the buffer pointers.
2010-02-20Fix PLT rewrite when prelinking fails on 32-bit sparc.David S. Miller
When prelinking fails we have to rewrite the PLT, but the code doing so forgets to adjust all rela->r_offset addresses by the location of where the object was actually mapped.
