("[PATCH for-5.2 0/3] linux-user: fix various sparc64 guest bugs")
This series fixes a few more issues with our sparc linux-user
sparc64_get_context() and sparc64_set_context() implementation:
* we weren't handling FPU regs correctly, and also the way
we coded the handling triggered Coverity warnings
* some stray pointless error checks
* we shouldn't restore %g7 in set_context
* we weren't saving and restoring tstate correctly
My main aim here was to deal with the Coverity errors, but
the rest are things I noticed while I was working on the
code or which had fixme comments, and I figured I'd fix
them while the code was fresh in my mind.
thanks
