      MIPS: Get rid of branches to .subsections. · 7837314d
      Ralf Baechle authored
      It was a nice optimization - on paper at least.  In practice it results in
      branches that may exceed the maximum legal range for a branch.  We can
      fight that problem with -ffunction-sections but -ffunction-sections again
      is incompatible with -pg used by the function tracer.
      
      By rewriting the loop around all simple LL/SC blocks to C we reduce the
      amount of inline assembler and at the same time allow GCC to often fill
      the branch delay slots with something sensible or whatever else clever
      optimization it may have up in its sleeve.
      
      With this optimization gone we also no longer need -ffunction-sections,
      so drop it.
      
      This optimization was originally introduced in 2.6.21, commit
      5999eca25c1fd4b9b9aca7833b04d10fe4bc877d (linux-mips.org) rsp.
      f65e4fa8 (kernel.org).
      
      Original fix for the issues which caused me to pull this optimization by
      Paul Gortmaker <paul.gortmaker@windriver.com>.
