Donenfeld # Date: Wed Sep 25 19:50:22 2024 +0200 # # 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") # Signed-off-by: Jason A.
