Patchc08e20d
"arm: Add v7_invalidate_l1 to cache-v7.S" added a generic version of this function and removed all platform specific versions, while4898de3
"ARM: PRIMA2: add new SiRFmarco SMP SoC infrastructures" added another one, leading to a link error. I verified that the two are identical, so we can just remove the one in mach-prima2. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
