Recent MIPS toolchains complain about the use of an immediate larger
than 32bits when compiling a 32bit kernel, leading to the following
build failure:
{standard input}: Assembler messages:
{standard input}:131: Error: number (0x9000000080000000) larger than 32
bits
{standard input}:154: Error: number (0x9000000080000000) larger than 32
bits
{standard input}:191: Error: number (0x9000000080000000) larger than 32
bits
Fix this by specifying registers are 64bit via the .set gp=64 directive.
Since IP22 is the default MIPS machine, this is causing allnoconfig
build failures.
