b7d7ef87e1 [ARM] 3499/1: Fix VFP FPSCR corruption for double exception case 
Patch from George G. Davis

The ARM VFP FPSCR register is corrupted when a condition flags modifying
VFP instruction is followed by a non-condition flags modifying VFP
instruction and both instructions raise exceptions.  The fix is to
read the current FPSCR in between emulation of these two instructions
and use the current FPSCR value when handling the second exception.

928bd1b470 [ARM] vfp: fix leak of VFP_NAN_FLAG into FPSCR 
The VFP code can leak VFP_NAN_FLAG into the FPSCR. It doesn't correspond
to any real FPSCR bit (and overlaps one of the exception flags).

da41119af7 [PATCH] ARM: Don't force SIGFPE 
We were forcing SIGFPE on to a user program for no good reason.
Use send_sig_info() instead.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
