Stefan Weil 80cba1b71e hw/9pfs: Fix potential memory leak and avoid reuse of freed memory 
The leak was reported by cppcheck.

Function proxy_init also calls g_free for ctx->fs_root.
Avoid reuse of this memory by setting ctx->fs_root to NULL.

Paolo Bonzini 0d09e41a51 hw: move headers to include/ 
Many of these should be cleaned up with proper qdev-/QOM-ification.
Right now there are many catch-all headers in include/hw/ARCH depending
on cpu.h, and this makes it necessary to compile these files per-target.
However, fixing this does not belong in these patches.

Paolo Bonzini b4a42f8138 hw: move qdev-monitor.o to toplevel directory 
qdev-monitor.c is the only "core qdev" file that is not used in
user-mode emulation, and it does not define anything that is used
by hardware models.  Remove it from the hw/ directory and
remove hw/qdev-monitor.h from hw/qdev.h too; this requires
some files to have some new explicitly includes.

Peter Maydell 2afee49fc4 virtio-9p-proxy: Fix typo causing compile failure on 32 bit hosts 
Fix a compile failure on 32 bit hosts (integer constant is too large
for 'unsigned long' type) by correcting a typo where the mask used
for filling in the second f_fsid word had too many 'F's in it.
Also drop the 'L' suffix that allowed this typo to go undetected on
64 bit hosts.
