      Pull RISC-V fixes from Palmer Dabbelt:
       "This contains a handful of fixes I'd like to target for rc3.
      
        Most of them fix issues with the conversion of our vDSO to C. There is
        also one fix to the SiFive PRCI driver that I picked up as it's
        causing boot issues on the hardware.
      
         - A fix to allow kernels with dynamic ftrace to use the vDSO.
      
         - Some build fixes for the C vDSO functions.
      
         - A fix to the PRCI driver's memory allocation, which was the cause
           of some boot panics with FREELIST_RANDOM"

      Pull arm64 fixes from Will Deacon:
       "The big fix here is to our vDSO sigreturn trampoline as, after a
        painfully long stint of debugging, it turned out that fixing some of
        our CFI directives in the merge window lit up a bunch of logic in
        libgcc which has been shown to SEGV in some cases during asynchronous
        pthread cancellation.
      
        It looks like we can fix this by extending the directives to restore
        most of the interrupted register state from the sigcontext, but it's
        risky and hard to test so we opted to remove the CFI directives for
        now and rely on the unwinder fallback path like we used to.
      
         - Fix unwinding through vDSO sigreturn trampoline
      
         - Fix build warnings by raising minimum LD version for PAC
      
         - Whitelist some Kryo Cortex-A55 derivatives for Meltdown and SSB
      
         - Fix perf register PC reporting for compat tasks
      
         - Fix 'make clean' warning for arm64 signal selftests
      
         - Fix ftrace when BTI is compiled in
      
         - Avoid building the compat vDSO using GCC plugins"
