If KVM_CREATE failed on s390x, we print a hint to enable the switch_amode
kernel parameter. This only applies to old kernels, and only if the
error was -EINVAL. Moreover, with new kernels, the most likely reason
for -EINVAL is that pgstes were not enabled.
Let's update the error message to give a better hint on where things
may need fixing.

Access register mode is one of the modes that control dynamic address
translation. In this mode the address space is specified by values of
the access registers. The effective address-space-control element is
obtained from the result of the access register translation. See
the "Access-Register Introduction" section of the chapter 5 "Program
Execution" in "Principles of Operations" for more details.
When the CPU is in AR mode, the s390_cpu_virt_mem_rw() function must
know which access register number to use for address translation.
This patch does several things:
- add new parameter 'uint8_t ar' to that function
- decode ar number from intercepted instructions
- pass the ar number to s390_cpu_virt_mem_rw(), which in turn passes it
to the KVM_S390_MEM_OP ioctl.

chars), extended machine name encoding (equals 2 for UTF-8) and UUID.
STSI322 qemu handler also finds a highest virtualization level in
level-3 virtualization stack that doesn't support Extended Names
(Ext Name delimiter) and propagates zero Ext Name to all levels below,
because this level is not capable of managing Extended Names of lower

This fixes ioctl behavior on powerpc e6500 platforms with 64bit kernel and 32bit
userspace. The current type cast has no effect there and the value passed to the
kernel is still 0. Probably an issue related to the compiler, since I'm assuming
the same configuration works on a similar setup on x86.
Also ensure consistency with previous type cast in TRACE message.

I discovered a problem when trying to build QEMU statically with gcc.
libm is an element of LIBS while libpixman-1 is an element in
libs_softmmu. Libpixman references functions in libm, so the original
ordering makes linking fail.
This fix is to reorder $libs_softmmu and $LIBS to make -lm appear after
-lpixman-1. However I'm not quite sure if this is the right fix, hence
the RFC tag.
Normally QEMU is built with c++ compiler which happens to link in libm
(at least this is the case with g++), so building QEMU statically
normally just works and nobody notices this issue.

This adds "--enable-tcmalloc" and "--disable-tcmalloc" to allow linking
to libtcmalloc from gperftools.
tcmalloc is a malloc implementation that works well with threads and is
fast, so it is good for performance.
It is disabled by default, because the MALLOC_PERTURB_ flag we use in
tests doesn't work with tcmalloc. However we can enable tcmalloc
specific heap checker and profilers later.
An IOPS gain can be observed with virtio-blk-dataplane, other parts of
QEMU will directly benefit from it as well:
