3b023756b1 char-socket: correctly set has_reconnect when parsing QemuOpts
qemu_chr_parse_socket() fills all ChardevSocket fields, but that
doesn't reflect correctly the arguments given with the options / on
the command line. "reconnect" takes a number as argument, and the
default value is 0, which doesn't help to identify the missing
option. The other arguments have default values that are less
problematic, leave them set by default for now.

b70d6afe4d qga-win: changing --retry-path option behavior
Currently whenever the qemu-ga's service doesn't find the virtio-serial
the run_agent() loops in a QGA_RETRY_INTERVAL (default 5 seconds)
intervals and try to restart the qemu-ga which causes a synchronous loop.
Changed to wait and listen for the serial events by registering for
notifications a proper serial event handler that deals with events:
  DBT_DEVICEARRIVAL        indicates that the device has been inserted and
                           is available
  DBT_DEVICEREMOVECOMPLETE indicates that the devive has been removed
Which allow us to determine when the channel path is available for the
qemu-ga to restart.

ebc88c0ecf qga-win: install service with --retry-path set by default
It's nicer from a management perspective that the agent can survive
hotplug/unplug of the channel device, or be started prior to the
installation of the channel device's driver without and still be able
to resume normal function afterward. On linux there are alternatives
like systemd to support this, but on w32 --retry-path is the only
option so it makes sense to set it by default when installed as a
w32 service.

d951fadad6 qga: add --retry-path option for re-initializing channel on failure
This adds an option to instruct the agent to periodically attempt
re-opening the communication channel after a channel error has
occurred. The main use-case for this is providing an OS-independent
way of allowing the agent to survive situations like hotplug/unplug of
the communication channel, or initial guest set up where the agent may
be installed/started prior to the installation of the channel device's
driver.

There are nicer ways of implementing this functionality via things
like systemd services, but this option is useful for platforms like
*BSD/w32.

Currently a channel error will result in the GSource for that channel
being removed from the GMainLoop, but the main loop continuing to run.
That behavior results in a dead loop when --retry-path isn't set, and
prevents us from knowing when to attempt re-opening the channel when
it is set, so we also force the loop to exit as part of this patch.

0f4d3a4912 qga: hang GAConfig/socket_activation off of GAState global
For w32 services we rely on the global GAState to access resources
associated with the agent within service_main(). Currently this is
sufficient for starting the agent since we open the channel once prior
to calling service_main(), and simply start the GMainLoop to start the
agent from within service_main().

Eventually we want to be able to also [re-]open the communication
channel from within service_main(), which requires access to
config/socket_activation variables, so we hang them off GAState in
preparation for that.

64f2674bbc cputlb: Merge tlb_flush_nocheck into tlb_flush_by_mmuidx_async_work
The difference between the two sets of APIs is now miniscule.

This allows tlb_flush, tlb_flush_all_cpus, and tlb_flush_all_cpus_synced
to be merged with their corresponding by_mmuidx functions as well.  For
accounting, consider mmu_idx_bitmask = ALL_MMUIDX_BITS to be a full flush.

1308e02671 cputlb: Split large page tracking per mmu_idx
The set of large pages in the kernel is probably not the same
as the set of large pages in the application.  Forcing one
range to cover both will flush more often than necessary.

This allows tlb_flush_page_async_work to flush just the one
mmu_idx implicated, which in turn allows us to remove
tlb_check_page_and_flush_by_mmuidx_async_work.

60a2ad7d86 cputlb: Move cpu->pending_tlb_flush to env->tlb_c.pending_flush
Protect it with the tlb_lock instead of using atomics.
The move puts it in or near the same cacheline as the lock;
using the lock means we don't need a second atomic operation
in order to perform the update.  Which makes it cheap to also
update pending_flush in tlb_flush_by_mmuidx_async_work.

f5177798d8 scripts: report on author emails that are mangled by the mailing list
In some cases the Author: email address in patches submitted to the
list gets mangled such that it says

    John Doe via Qemu-devel <qemu-devel@nongnu.org>

This change is a result of workarounds for DMARC policies.

Subsystem maintainers accepting patches need to catch these and fix
them before sending pull requests, so a checkpatch.pl test is highly
desirable.

00b9e2950b block: drop moderated sheepdog mailing list from MAINTAINERS file
The sheepdog mailing list is setup to stop and queue messages from
non-subscribers, pending moderator approval. Unfortunately it seems
that the moderation queue is not actively deadlt with. Even when messages
are approved, the sender is never added to the whitelist, so every
future mail the same sender continues to get stopped for moderation.

MAINTAINERS entries should be responsive and not uneccessarily block
mails from QEMU contributors, so drop the sheepdog mailing list.

3d63da16fb migration: avoid segmentfault when take a snapshot of a VM which being migrated
During an active background migration, snapshot will trigger a
segmentfault. As snapshot clears the "current_migration" struct
and updates "to_dst_file" before it finds out that there is a
migration task, Migration accesses the null pointer in
"current_migration" struct and qemu crashes eventually.

09b9ee643f i386: Add PKU on Skylake-Server CPU model
As the release document ref below link (page 13):
https://software.intel.com/sites/default/files/managed/c5/15/\
architecture-instruction-set-extensions-programming-reference.pdf

PKU is supported in Skylake Server (Only Server) and later, and
on Intel(R) Xeon(R) Processor Scalable Family. So PKU is supposed
to be in Skylake-Server CPU model. And PKU's CPUID has been
exposed to QEMU. But PKU can't be find in Skylake-Server CPU
model in the code. So this patch will fix this issue in
Skylake-Server CPU model.

c7a88b52f6 i386: Add new model of Cascadelake-Server
New CPU models mostly inherit features from ancestor Skylake-Server,
while addin new features: AVX512_VNNI, Intel PT.
SSBD support for speculative execution
side channel mitigations.

Note:

On Cascadelake, some capabilities (RDCL_NO, IBRS_ALL, RSBA,
SKIP_L1DFL_VMENTRY and SSB_NO) are enumerated by MSR.
These features rely on MSR based feature support patch.
Will be added later after that patch's in.
