RISC-V updates for late v7.2-rc

Browse source

- Fix a fault caused when the RISC-V Zbb-enabled strlen() is executed
   on a string that ends right before a page boundary, when the next
   page is unmapped
 
 - Fix a race with the misaligned vector performance testing code that
   can prevent the outcome of the test from being stored into the vDSO
   cache
 
 - Fix a kernel warning generated by the ftrace code when
   ftrace_modify_call_code() runs against a ftrace-traced function
   where a kprobe has already been attached.  This shows up in the bpf
   kselftests
