ppc patch queue 2016-09-23

This pull request supersedes ppc-for-2.8-20160922.  There was a clang
build error in that, and I've also added one extra patch in the new pull.

Included in this set of ppc and spapr patches are:
    * TCG implementations for more POWER9 instructions
    * Some preliminary XICS fixes in preparataion for the pnv machine type
    * A significant ADB (Macintosh kbd/mouse) cleanup
    * Some conversions to use trace instead of debug macros
    * Fixes to correctly handle global TLB flush synchronization in
      TCG.  This is already a bug, but it will have much more impact
      when we get MTTCG
    * Add more qtest testcases for Power
    * Some MAINTAINERS updates
    * Assorted bugfixes
    * Add the basics of NUMA associativity to the spapr PCI host bridge

This touches some test files and monitor.c which are technically
outside the ppc code, but coming through this tree because the changes
are primarily of interest to ppc.

Without this patch, a number of Mips syscalls will be logged in the following
way (in this example, this is an invocation of accept4()):

  86906 Unknown syscall 4334

This patch provides standard Qemu's strace output for such cases, like this:

  95861 accept4(3,1996486000,1996486016,128,0,0) = 5

Such output may be further improved by providing strace-related functions
that handle only particular syscalls, but this is beyond the scope of
this patch.

EDQUOT is defined for Mips platform in Linux kernel in such a way
that it has different value than on most other platforms. However,
correspondent TARGET_EDQUOT for Mips is missing in Qemu code. Moreover,
TARGET_EDQUOT is missing from the table for conversion of error codes
from host to target. This patch fixes these problems.

Without this patch, syscalls add_key(), keyctl(), link(), mkdir(), mknod(),
open(), rename(), request_key(), setxattr(), symlink(), and write() will not
be able to return the right error code in some scenarios on Mips platform.
(Some of these syscalls are not yet supported in Qemu, but once they are
supported, they will need correct EDQUOT handling.)

The function that is changed in this patch is supposed to indicate that
there was certain argument rearrangement related to 64-bit arguments on
32-bit platforms. The background on such rearrangements can be found,
for example, in the man page for syscall(2).

However, for 64-bit Mips architectures there is no such rearrangement,
and this patch reflects it.

Structure flock is defined for Mips in a way different from any

arch/mips/include/uapi/asm/fcntl.h, line 63 (for Mips)
include/uapi/asm-generic/fcntl.h, line 195 (for all other platforms)

This patch fix this problem, by amending structure target_flock,
for Mips only.

Besides, this patch fixes LTP tests fcntl11, fcntl17, fcntl19, fcntl20,

A number of different places across the code base use CONFIG_UUID. Some
of them are soft dependency, some are not built if libuuid is not
available, some come with dummy fallback, some throws runtime error.

It is hard to maintain, and hard to reason for users.

Since UUID is a simple standard with only a small number of operations,
it is cleaner to have a central support in libqemuutil. This patch adds
qemu_uuid_* functions that all uuid users in the code base can
rely on. Except for qemu_uuid_generate which is new code, all other
functions are just copy from existing fallbacks from other files.

Note that qemu_uuid_parse is moved without updating the function
signature to use QemuUUID, to keep this patch simple.

Now that we allow CPU hot unplug on a few platforms, we can end up in a
situation where we don't have a CPU with index 0.  Or at least we could,
if we didn't have code to explicitly prohibit unplug of CPU 0.

Longer term we want to allow CPU 0 unplug, this patch is an early step in
allowing this, by removing an assumption in the monitor code that CPU 0
always exists.

Only the POWER[789] CPUs should have the ARCH_206 bit set. This is what the
linux kernel does. I guess this was also the intention of commit 0e019746.
We have to make sure all *206 bits are set.

Before this patch, the flags check in the GET_FEATURES2 macro returned true
if _any_ bit was set. This worked well as long as there was only one bit
set in the 'flag' parameter. But as explained before, we have to make sure
all bits in the 'flag' parameter are set.
