Hi,

for 2.6 kernels, arch/mips/Makefile contains the following lines:

ifdef CONFIG_MIPS64
gcc-abi                 = 64
gas-abi                 = 32
tool-prefix             = $(64bit-tool-prefix)
UTS_MACHINE             := mips64
endif

Is it intentional that gcc-abi and gas-abi are different? This
results in '-Wa,-32' appearing on gcc's command line, causing
the asembler to complain:

Error: -mgp64 used with a 32-bit ABI

If I change gas-abi to 64, this error goes away.
