#     powerpc/vdso: allow r30 in vDSO code generation of getrandom
#     
#     For gettimeofday, -ffixed-r30 was passed to work around a bug in Go
#     code, where the vDSO trampoline forgot to save and restore this register
#     across function calls. But Go requires a different trampoline for every
#     call, and there's no reason that new Go code needs to be broken and add
#     more bugs. So remove -ffixed-r30 for getrandom.
#     
#     Fixes: 8072b39c3a75 ("powerpc/vdso: Wire up getrandom() vDSO implementation on VDSO64")
