Subject: [Qemu-devel] [PATCH] Fix CPU chaining in linux-user emulation
Hi,
This patch fixes chaining of CPU instances. It was simply trashed with the
memcpy() thus causing problems in threaded programs (N > 2): an infinite
loop in next cpu_init().

Subject: [Qemu-devel] [PATCH] Fix guest x86/amd64 helper_fprem/helper_fprem1
The helpers for x86/amd64 fprem and fprem1 in target-i386/helper.c are
significantly borked and, for example, cause konqueror in RedHat8 (x86
guest) to go into an infinite loop when displaying http://news.bbc.co.uk.
helper_fprem has the following borkage:
- various Inf/Nan/zero inputs not handled correctly
- incorrect rounding when converting negative 'dblq' to 'q'
- incorrect order of assignment to C bits (0,3,1 not 0,1,3)
helper_fprem1 has those problems and is also incorrect about the points
at which its rounding needs to differ from that of helper_fprem.
Patch below fixes all these. It brings the fprem and fprem1 behaviour
very much closer to the hardware -- not identical, but close. Some
+0.0 results should really be -0.0 and there may still be other differences.
Anyway konquerer no longer loops with the patch applied.
