a59629fcc6 rcu: do not create thread in pthread_atfork callback
If QEMU forks after the CPU threads have been created, qemu_mutex_lock_iothread
will not be able to do qemu_cpu_kick_thread.  There is no solution other than
assuming that forks after the CPU threads have been created will end up in an
exec.  Forks before the CPU threads have been created (such as -daemonize)
have to call rcu_after_fork manually.

Notably, the oxygen theme for GTK+ forks and shows a "No such process" error
without this patch.

This patch can be reverted once the iothread loses the "kick the TCG thread"
magic.

User-mode emulation does not use the iothread, so it can also call
rcu_after_fork.

a18bb417e9 qom: Fix object_property_add_alias() with [*]
Commit 8074264 (qom: Add description field in ObjectProperty struct)
introduced property descriptions and copied them for alias properties.

Instead of using the caller-supplied property name, use the returned
property name for setting the description. This avoids an Error when
setting a property description for a property with literal "[*]" that
doesn't exist due to automatic property naming in object_property_add().

fc3d8e1138 AHCI: Protect cmd register
Many bits in the CMD register are supposed to be strictly read-only.
We should not be deleting them on every write.

As a side-effect: pay explicit attention to when a guest marks off
the FIS Receive or Start bits, and disable the status bits ourselves,
instead of letting them implicitly fall off.

a13ab5a35b AHCI: Do not (re)map FB/CLB buffers while not running
The FIS Receive Buffer and Command List Buffer pointers
should not be edited while the FIS receive engine or
Command Receive engines are running.

Currently, we attempt to re-map the buffers every time they
are adjusted, but while the AHCI engines are off, these registers
may contain stale values, so we should not attempt to re-map these
values until the engines are reactivated.

4e60a250d3 hw/net/e1000: fix integer endianness
It's detected by coverity.In is_vlan_packet s->mac_reg[VET] is
unsigned int but is dereferenced as a narrower unsigned short.
This may lead to unexpected results depending on machine
endianness.

fc3959e466 block: Fix unaligned zero write
If the zero write is not aligned, bdrv_co_do_pwritev will segfault
because of accessing to the NULL qiov passed in by bdrv_co_write_zeroes.
Fix this by allocating a local qiov in bdrv_co_do_pwritev if the request
is not aligned. (In this case the padding iovs are necessary anyway, so
it doesn't hurt.)

Also add a check at the end of bdrv_co_do_pwritev to clear the zero flag
if padding is involved.

f18c69cfc5 exec: avoid possible overwriting of mmaped area in qemu_ram_remap
It is not necessary to munmap an area before remapping it with MAP_FIXED;
if the memory region specified by addr and len overlaps pages of any
existing mapping, then the overlapped part of the existing mapping will
be discarded.

On the other hand, if QEMU does munmap the pages, there is a small
probability that another mmap sneaks in and catches the just-freed
portion of the address space.  In effect, munmap followed by
mmap(MAP_FIXED) is a use-after-free error, and Coverity flags it
as such.  Fix it.

fda276c7aa target-ppc: Remove POWER5+ v0.0 that never existed
IBM uses low 16bits to specify the chip version of a POWER CPU.
So there has never been an actual silicon with PVR = 0x003B0000.
The first silicon would have PVR 0x003B0100 but it is very unlikely
to find it in any machine shipped to any customer as it was too raw.

This removes CPU_POWERPC_POWER5P_v00 definition and changes
POWER5+ and POWERgs aliases (which are synonyms) to point to
POWER5+_v2.1 which can still be found in real machines.

4c56440d67 spapr: Add missing checks for NULL pointers and report failures
This fixes potential runtime crashes and two warnings from Coverity.

The new error message does not add  a prefix "qemu:" because that is
already done in function hw_error. It also starts with an uppercase
letter because that seems to be the mostly used form.

8e7ba4ed3a sparc: memory: Replace memory_region_init_ram with memory_region_allocate_system_memory
Commit 0b183fc871:"memory: move mem_path handling to
memory_region_allocate_system_memory" split memory_region_init_ram and
memory_region_init_ram_from_file. Also it moved mem-path handling a step
up from memory_region_init_ram to memory_region_allocate_system_memory.

Therefore for any board that uses memory_region_init_ram directly,
-mem-path is not supported.

Fix this by replacing memory_region_init_ram with
memory_region_allocate_system_memory.
