2011-09-09qemu_vmalloc: align properly for transparent hugepages and KVMAvi Kivity
To make good use of transparent hugepages, KVM requires that guest-physical and host-virtual addresses share the low 21 bits (as opposed to just the low 12 bits normally required).

2011-09-09curses: fix garbling when chtype != longDevin J. Pohly
Qemu currently assumes that chtype is typedef'd to unsigned long, but this is not necessarily the case (ncurses, for instance, can configure this at build-time). This patch uses the predefined chtype if qemu is configured for curses support and falls back to unsigned long otherwise. Fixes bug 568614. Signed-off-by: Devin J.

2011-09-09tcg/ppc64: Fix zero extension code generation bug for ppc64 hostThomas Huth
The ppc64 code generation backend uses an rldicr (Rotate Left Double Immediate and Clear Right) instruction to implement zero extension of a 32 bit quantity to a 64 bit quantity (INDEX_op_ext32u_i64). However this is wrong - this instruction clears specified low bits of the value, instead of high bits as we require for a zero extension. It should instead use an rldicl (Rotate Left Double Immediate and Clear Left) instruction. Presumably amongst other things, this causes the SLOF firmware image used with -M pseries to not boot on a ppc64 host. It appears this bug was exposed by commit 0bf1dbdcc935dfc220a93cd990e947e90706aec6 (tcg/ppc64: fix 16/32 mixup) which enabled the use of the op_ext32u_i64 operation on the ppc64 backend.

2011-09-09xen-mapcache: Fix rlimit set size.Anthony PERARD
Previously, the address space soft limit was set mcache_max_size. So, before the mcache_max_size was reached by the mapcache, QEMU was killed for overuse of the virtual address space. This patch fix that by setting the soft limit the maximum than can have QEMU. So the soft and hard limit are always set to RLIM_INFINITY if QEMU is privileged. In case QEMU is not run as root and the limit is too low, the maximum mapcache size will be set the rlim_max - 80MB because observed that QEMU use 75MB more than the maximum mapcache size after several empirical tests.

2011-09-09configure: Avoid duplicate flags when calling compile_progStefan Weil
This patch removes redundant shell code and cleans it a little bit. Shell macro compile_prog takes two arguments: local_cflags and local ldflags. $QEMU_CFLAGS is added automatically to the cflags, so there is no need to pass it as an argument. It is also unnecessary to pass -Werror twice. $flag is a compiler warning option, so it should be in local_cflags instead of local_ldflags.
