2fb0c09f4f vnc: Fix compilation with --enable-vnc-png
Commit f26e428da5 fixed compilation
with --enable-vnc-png, but broke it with --enable-vnc-png.

The breakage is caused by pngconfig.h which checks whether
setjmp.h was already included and fails because qemu-common.h
includes setjmp.h.

The check is disabled by defining PNG_SKIP_SETJMP_CHECK.

f44c99607a TCG/Sparc64: use stack for TCG temps
Use stack instead of temp_buf array in CPUState for TCG temps.

On Sparc64, stack pointer is not aligned but there is a fixed bias of 2047,
so don't try to enforce alignment.

345649c054 TCG: remove broken stack allocation for call arguments
The code for stack allocation for call arguments is way too simplistic
to actually work on targets with non-trivial stack allocation policies,
e.g. ppc64. We've also already allocated TCG_STATIC_CALL_ARGS_SIZE worth
of stack for calls which should be well more than any helper needs.

Remove broken dynamic stack allocation code and replace it with an assert.
Should dynamic stack allocation ever be needed again, target specific
functions should be added.

Thanks to Richard Henderson for the analysis.

cea5f9a28f cpu-exec.c: avoid AREG0 use
Make functions take a parameter for CPUState instead of relying
on global env. Pass CPUState pointer to TCG prologue, which moves

Thanks to Peter Maydell and Laurent Desnogues for the ARM prologue

e694d4e289 x86: use caller supplied CPUState for interrupt related stuff
Several x86 specific functions are called from cpu-exec.c with the
assumption that global env register is valid. This will be changed
later, so make the functions use caller supplied CPUState parameter.

It would be cleaner to move the functions to helper.c, but there are
quite a lot of dependencies between do_interrupt() and other functions.

Add helpers for svm_check_intercept() and cpu_cc_compute_all() instead
of calling the helper (which uses global env, AREG0) directly.

f9245e100f configure: Don't create symlinks to nonexistent targets
When we create the symlinks to source tree files, don't create them
if the file is not actually present in the source tree; this will
happen if the file is in a git submodule that wasn't checked out.

This also avoids the odd effect where an in-source-tree configure
will end up creating the missing file as a symlink to itself.

Diagnose the case where the user asked for a NIC via "-net nic"

user asked for two NICs but the board only supports one). Note
that this diagnostic doesn't apply to NICs created through -device,
