gnttab: make sure grant map operations don't skip their IOMMU part
Two almost simultaneous mapping requests need to make sure that at the
completion of the earlier one IOMMU mappings (established explicitly
here in the PV case) have been put in place. Forever since the splitting
of the grant table lock a violation of this has been possible (using
simplified pin counts, as it doesn't matter whether we talk about read
or write mappings here):
initial state: act->pin = 0
vCPU A: progress the operation past the dropping of the locks after the
act->pin updates (act->pin = 1, old_pin = 0, act_pin = 1)
vCPU B: progress the operation past the dropping of the locks after the
act->pin updates (act->pin = 2, old_pin = 1, act_pin = 2)
vCPU B: (re-)acquire both gt locks, mapkind() returns 0, but both
iommu_legacy_map() invocations get skipped due to non-zero
old_pin
vCPU B: return to caller without IOMMU mapping
vCPU A: (re-)acquire both gt locks, mapkind() returns 0,
iommu_legacy_map() gets invoked
With the locks dropped intermediately, whether to invoke
iommu_legacy_map() must depend on only the return value of mapkind()
and of course the kind of mapping request being processed, just like
is already the case in unmap_common().
Also fix the style of the adjacent comment, and correct a nearby one
still referring to a prior name of what is now mapkind().

x86: avoid HPET use on certain Intel platforms
Linux commit fc5db58539b49351e76f19817ed1102bf7c712d0 says
"Some Coffee Lake platforms have a skewed HPET timer once the SoCs entered
PC10, which in consequence marks TSC as unstable because HPET is used as
watchdog clocksource for TSC."
Follow this for Xen as well. Looking at its patch context made me notice
they have a pre-existing quirk for Bay Trail as well. The comment there,
however, points at a Cherry Trail document. Looking at the datasheets of
both, there appear to be similar issues, so go beyond Linux'es coverage
and exclude both. Also key the disable on the PCI IDs of the actual
affected devices, rather than those of 00:00.0.
Apply the workarounds only when the use of HPET was not explicitly
requested on the command line and when use of (deep) C-states was not
disabled.
Adjust a few types in touched or nearby code at the same time.

sched: fix resuming from S3 with smt=0
When resuming from S3 and smt=0 or maxcpus= are specified we must not
do anything in cpu_schedule_callback(). This is not true today for
taking down a cpu during resume.
If anything goes wrong during resume all the scheduler related error
handling is in cpupool.c, so we can just bail out early from
cpu_schedule_callback() when suspending or resuming.
This fixes commit 0763cd2687897b55e7 ("xen/sched: don't disable
scheduler on cpus during suspend").

x86: clear per cpu stub page information in cpu_smpboot_free()
cpu_smpboot_free() removes the stubs for the cpu going offline, but it
isn't clearing the related percpu variables. This will result in
crashes when a stub page is released due to all related cpus gone
offline and one of those cpus going online later.
Fix that by clearing stubs.addr and stubs.mfn in order to allocate a
new stub page when needed, irrespective of whether the CPU gets parked
or removed.

IRQ: u16 is too narrow for an event channel number
FIFO event channels allow ports up to 2^17, so we need to use a wider
field in struct pirq. Move "masked" such that it may share the 8-byte
slot with struct arch_pirq on 64-bit arches, rather than leaving a
7-byte hole in all cases.
Take the opportunity and also add a comment regarding "arch" placement
within the structure.

From: Olaf Hering <o...@aepfle.de>
Subject: libxl: lock qemu machine for hvm
References: bsc#1159755
libxl must not use 'xenfv' as qemu machine type because it maps just to
'pc', which means 'the latest variant of pc-i440fx'. Each new qemu
version will make slightly incompatible changes to this machine type,
which makes it impossible to migrate a domU from one qemu to another.
This happend to work until qemu-3, but broke with qemu-4:
With qemu.git commit 7fccf2a06890e3bc3b30e29827ad3fb93fe88fea a new
member smbus_no_migration_support was added, and enabled in two places.
With qemu.git commit 4ab2f2a8aabfea95cc53c64e13b3f67960b27fdf the
vmstate_acpi got new elements, which are conditionally filled. As a
result, an incoming migration expected smbus related data unless smbus
migration was disabled for a given MachineClass.
Since qemu commit 7fccf2a06890e3bc3b30e29827ad3fb93fe88fea forgot to
handle xenfv, live migration to receiving hosts using qemu-4.0 and later
is broken.
Start all new domUs with 'pc-i440fx-3.1' instead of 'xenfv'.
