I tried to reproduce the issue with stock FSF GCC 5.2.0 and binutils 2.24,
2.25 and 2.26 and the commit ID and .config from this thread, no luck.

The old case btw, affects ip22 with a random_config:

  CC      arch/mips/mm/sc-ip22.o
{standard input}: Assembler messages:
{standard input}:137: Error: number (0x9000000080000000) larger than 32 bits
{standard input}:162: Error: number (0x9000000080000000) larger than 32 bits
scripts/Makefile.build:258: recipe for target 'arch/mips/mm/sc-ip22.o' failed
make[2]: *** [arch/mips/mm/sc-ip22.o] Error 1
scripts/Makefile.build:403: recipe for target 'arch/mips/mm' failed
make[1]: *** [arch/mips/mm] Error 2
Makefile:947: recipe for target 'arch/mips' failed
make: *** [arch/mips] Error 2

and I was able to reproduce it with binutils 2.26 and commit
c517d838eb7d07bbe9507871fab3931deccff539 ("Linux 4.0-rc1").  The code
in question looks like:

static inline void indy_sc_wipe(unsigned long first, unsigned long last)
{
        unsigned long tmp;

        __asm__ __volatile__(
        ".set\tpush\t\t\t# indy_sc_wipe\n\t"
        ".set\tnoreorder\n\t"
        ".set\tmips3\n\t"
        ".set\tnoat\n\t"
        "mfc0\t%2, $12\n\t"
        "li\t$1, 0x80\t\t\t# Go 64 bit\n\t"
        "mtc0\t$1, $12\n\t"

        "dli\t$1, 0x9000000080000000\n\t"
[...]

The same commit, same toolchain with ip22_defconfig builds just fine.
Seems the difference is CONFIG_CPU_R4X00 vs. CONFIG_CPU_R5000.  Not
sure why that would make a difference.
