Subject: MIPS: Fix MSA ld_*/st_* asm macros to use PTR_ADDU
From: James Hogan <[email protected]>
commit ea1688573426adc2587ed52d086b51c7c62eaca3 upstream.
The MSA ld_*/st_* assembler macros for when the toolchain doesn't support MSA use addu to offset the base address. However it is a virtual memory pointer so fix it to use PTR_ADDU which expands to daddu for 64-bit kernels.
