Applied, thanks.

Please update the changelog at https://wiki.qemu.org/ChangeLog/9.0
for any user-visible changes.

 From this list, do we pick something for stable?
It looks like

  tcg/optimize: Do not attempt to constant fold neg_vec
  linux-user: Fix waitid return of siginfo_t and rusage
  target/hppa: Fix IIAOQ, IIASQ for pa2.0

should be picked.

 From sh4 mac* et al, this can be picked too:

  target/sh4: mac.w: memory accesses are 16-bit words

but I dunno about the others:

  target/sh4: Merge mach and macl into a union
  target/sh4: Fix mac.l with saturation enabled
  target/sh4: Fix mac.w with saturation enabled
  target/sh4: add missing CHECK_NOT_DELAY_SLOT
  target/m68k: Map FPU exceptions to FPSR register

A long(ish) DisasContextBase series leading to

   accel/tcg: Improve can_do_io management

probably should not go to stable.

Adding changes authors and reviewers to the Cc list
for comments.

Thanks,

Yes.

This is for hppa64, so not further back than 8.2, or not at all -- hppa64 is really still 
in development.

Probably not, or at least not further back than 8.2.

We had a few other fixes for hppa64 for 8.2.
I was unsure about this since hppa64 appeared in 8.2
for the first time and sure thing it contains a ton
of bugs.

This one is a bit more difficult as it also needs
7d50b69660 "target/hppa: Use gva_offset_mask() everywhere", -
I wont force it in, despite it being a small change.

I picked all this for 8.2 but not for 7.2.  For 7.2,
there's quite some context missing in there.  Only
"add missing CHECK_NOT_DELAY_SLOT" is okay. Dunno
how relevant all these 6 changes for 7.2 are.

Thank you for the info!
