Revision 8356c379cfba8b1b90b0a2423f6afbbe2cdc5d91 authored by Palmer Dabbelt on 21 May 2020, 20:28:26 UTC, committed by Palmer Dabbelt on 21 May 2020, 20:28:26 UTC 
RISC-V: gp_in_global needs register keyword
 
The Intel kernel build robot recently pointed out that I missed the
register keyword on this one when I refactored the code to remove local
register variables (which aren't supported by LLVM).  GCC's manual
indicates that global register variables must have the register keyword,
As far as I can tell lacking the register keyword causes GCC to ignore
the __asm__ and treat this as a regular variable, but I'm not sure how
that didn't show up as some sort of failure.
