[Qemu-devel] [PATCH v5 00/21] AArch64 preparation patchset

[Peter Maydell]

This patchset is v5 of the "preparation patchset" that started
off with Alex, was passed to John Rigby and now to me.

Things I've done to it:
 * various bits of cleanup for style and other minor things
 * a little shuffling and splitting of patches
 * made the 32 bit CPUs work in aarch64-softmmu
 * given aarch64 its own cpu_loop() in linux-user/main.c 
 * made sure NWFPE doesn't sneak into aarch64-linux-user
 * let aarch64 have a nearly clean slate for tb_flags

Individual patches have a summary of my changes in the commit.

I've left the 'global cpu_env variable' patch alone since
there wasn't any consensus about what the best approach was;
it's a pretty minor (and textually localized) thing anyway so
easy to fix in future if it becomes an actual problem.

With these patches:
 * new target aarch64-linux-user, which will run but
   SIGILL on all instructions
 * new target aarch64-softmmu, which will run all the 32 bit
   CPUs and board models; however there is no 64 bit CPU
   defined so it's a bit pointless except as a demonstration
   that we haven't broken the 32 bit code.

I'm generally happy with the patchset and think it could
be committed (except for the last two default-configs patchs
which actually enable the new targets), apart from the fact
that it's not actually terribly useful yet.

There's one patch in here which is obviously going to clash
with my "move cpu_set_tls and cpu_clone_regs to linux-user"
patch, but it will be easy enough to fix when that goes in.

Note that in general the 'signed-off-by:' lines from people
other than me should be taken to indicate credit/authorship
rather than "I'm happy with this patchset", given that I've
changed the patches as they passed through my hands.
