#     Pull powerpc fixes from Michael Ellerman:
#      "Some some more powerpc fixes for 5.12:
#     
#        - Fix an oops triggered by ptrace when CONFIG_PPC_FPU_REGS=n
#     
#        - Fix an oops on sigreturn when the VDSO is unmapped on 32-bit
#     
#        - Fix vdso_wrapper.o not being rebuilt everytime vdso.so is rebuilt
#     
#       Thanks to Christophe Leroy"
