description:
constify vcpu_set_affinity()'s second parameter
None of the callers actually make use of the function's returning of
the old affinity through its second parameter, and eliminating this
capability allows some callers to no longer use a local variable here,
reducing their stack footprint significantly when building with large
NR_CPUS.

x86/emulator: add feature checks for newer instructions
Certain instructions were introduced only after the i686 or original
x86-64 architecture, so we should not try to emulate them if the guest
is not seeing the respective feature enabled (or, worse, if the
underlying hardware doesn't support them). This affects fisttp,
movnti, and cmpxchg16b.

x86/mm/p2m: fix pod locking
The path p2m-lookup -> p2m-pt->get_entry -> 1GB PoD superpage ->
pod_demand_populate ends in the pod code performing a p2m_set_entry with
no locks held (in order to split the 1GB superpage into 512 2MB ones)
Further, it calls p2m_unlock after that, which will break the spinlock.
This patch attempts to fix that.

x86: small fixes to pcpu platform op handling
XENPF_get_cpuinfo should init the flags output field rather than only
modify it.
XENPF_cpu_online must check for the input CPU number to be in range.
XENPF_cpu_offline must also do that, and should also reject attempts to
offline CPU 0 (this fails in cpu_down() too, but preventing this here
appears more correct given that the code here calls
continue_hypercall_on_cpu(0, ...), which would be flawed if cpu_down()
would ever allow bringing down CPU 0 (and a distinct error code is
easier to deal with when debugging issues).

mem_event: move mem_event_domain out of struct domain
An upcoming change may increase the size of mem_event_domain. The result
is a build failure because struct domain gets larger than a page.
Allocate the room for the three mem_event_domain members at runtime.
v2:
- remove mem_ prefix from members of new struct

xenpaging: Fix c/s 23507:0a29c8c3ddf7 ("update machine_to_phys_mapping[] during page deallocation")
This patch clobbers page owner in free_heap_pages() before we are
finished using it. This means that a subsequent test to determine
whether it is safe to avoid safety TLB flushes incorrectly always
determines that it is safe to do so.
The fix is simple: we can defer the original patch's work until after
we are done with the page-owner field.
Thanks to Christian Limpach for spotting this one.

x86/emulator: properly handle lzcnt and tzcnt
These instructions are prefix selected flavors of bsf and bsr
respectively, and hence the presences of the F3 prefix must be handled
in the emulation code in order to avoid running into problems on newer

X86: Disable PCID/INVPCID for dom0
PCID (Process-context identifier) is a facility by which a logical
processor may cache information for multiple linear-address spaces.
INVPCID is an new instruction to invalidate TLB. Refer latest Intel SDM
http://www.intel.com/content/www/us/en/processors/architectures-software-developer-manuals.html
We disable PCID/INVPCID for dom0 and pv. Exposing them into dom0 and pv
may result in performance regression, and it would trigger GP or UD
depending on whether platform suppport INVPCID or not.
This patch disables PCID/INVPCID for dom0.

x86/mm: Don't lose track of the log dirty bitmap
hap_log_dirty_init unconditionally sets the top of the log dirty
bitmap to INVALID_MFN. If there had been a bitmap allocated, it is
then leaked, and the host crashes on an ASSERT when the domain is
cleaned up.

description:
After preparing a page for page-in, allow immediate fill-in of the page contents
p2m_mem_paging_prep ensures that an mfn is backing the paged-out gfn, and
transitions to the next state in the paging state machine for that page.
Foreign mappings of the gfn will now succeed. This is the key idea, as
it allows the pager to now map the gfn and fill in its contents.
Unfortunately, it also allows any other foreign mapper to map the gfn and read
its contents. This is particularly dangerous when the populate is launched
by a foreign mapper in the first place, which will be actively retrying the
map operation and might race with the pager. Qemu-dm being a prime example.
Fix the race by allowing a buffer to be optionally passed in the prep
operation, and having the hypervisor memcpy from that buffer into the newly
prepped page before promoting the gfn type.

tools/x86_64: Fix cpuid() inline asm to not clobber stack's red zone
Pushing stuff onto the stack on x86-64 when we do not specify
-mno-red-zone is unsafe. Since the complicated asm is due to register
pressure on i386, we simply implement an all-new simpler alternative
for x86-64.

tools/firmware: remove "_PS0/3" Method
Do not expose the ACPI power management "_PS0/3" Method to guest
firmware. According to section 3.4 of the APCI specification 4.0, PCI
device control the device power through its own specification but not
through APCI.
Qemu pushes "_PS0/3" to guest will cause a mess between ACPI PM and
PCI PM as a result of incorrect ACPI table shipped with the guest
BIOS, it may cause a failure of PCI device PM state transition(from
PCI_UNKNOWN to PCI_D0).

x86, amd: Disable GartTlbWlkErr when BIOS forgets it
This patch disables GartTlbWlk errors on AMD Fam10h CPUs if the BIOS
forgets to do is (or is just too old). Letting these errors enabled
can cause a sync-flood on the CPU causing a reboot.
The AMD BKDG recommends disabling GART TLB Wlk Error completely.

x86: add platform hypercall to retrieve pCPU-s' family, model, and stepping
With the recent hotplug changes to the Xen part of the microcode
loading, this allows the kernel driver to avoid unnecessary calls into
the hypervisor during pCPU hot-enabling: Knowing that the hypervisor
retains the data for already booted CPUs, only data for CPUs with a
different signature needs to be passed down. Since the microcode
loading code can be pretty verbose, avoiding to invoke it can make the
log much easier to look at in case of problems.

x86/ucode: fix for AMD Fam15 CPUs
Remove hardcoded maximum size a microcode patch can have. This is
dynamic now.
The microcode patch for family15h can be larger than 2048 bytes and
gets silently truncated.

x86/emulator: workaround for AMD erratum 573
The only cases where we might end up emulating fsincos (as any other
x87 operations without memory operands) are
- when a HVM guest is in real mode (not applicable on AMD)
- between two half page table updates in PAE mode (unlikely, and not
doing the emulation here does affect only performance, not
correctness)
- when a guest maliciously (or erroneously) modifies an (MMIO or page
table update) instruction under emulation (unspecified behavior)
Hence, in order to avoid the erratum to cause harm to the entire host,
don't emulate fsincos on the affected AMD CPU families.

As unmap_domain_pirq_emuirq() fails on a never mapped pIRQ, it must not
be called for the non-emu-IRQ case (to prevent the entire unmap

x86/vIRQ: IRR and TMR race condition bug fix
In vlapic_set_irq, we set the IRR register before the TMR. And the IRR
might be serviced before setting TMR, and even worse EOI might occur
before TMR setting, in which case the vioapic_update_EOI won't be
called, and further prevent all the subsequent interrupt injecting.
Reorder setting the TMR and IRR will solve the problem.
Besides, KVM has fixed a similar bug in:

libxc: Only retry mapping pages when ENOENT is returned
If the return value from the ioctl() is not ENOENT, it's possible that err[i]
will not be updated and libxc will just loop forever. Although it's unlikely
that err[i] would not be updated after the ioctl() gets through at least once,
it's better to be defensive.

Guests can not issue this command unconditionally because some buggy
toolstacks (such as EC2) do not ignore unknown commands properly.

tools/libxc: fix error handling in xc_mem_paging_load
xc_mem_paging_load() does not pass errors in errno and the actual
errno from xc_mem_event_control() is overwritten by munlock().
xenpaging_populate_page() needs to check errno, but with the switch to
xc_mem_paging_load() it could not receive ENOMEM anymore.
Update xc_mem_paging_load() to return -1 and preserve errno during
munlock().

If the first ioctl fails with ENOENT it means the command is known. If a
second attempt to map each gfn happens to fail then there is no need to
run the fallback code. Some gfns are paged and the fallback code would
not fix the failure. Instead return the EINVAL to the caller.

xenpaging: make file_op largefile aware
lseek() takes an off_t, the used "int << shiftsize" does not automatically
convert the int into a larger type. This leads to write errors with pagefiles
larger than 2G. Fix this by shifting an off_t instead of an int.

qemu: clean up MSI-X table handling
This patch does cleaning up of QEMU MSI handling. The fixes are:
1. Changes made to MSI-X table mapping handling to eliminate the small
windows in which guest could have access to physical MSI-X table.
2. MSI-X table is mapped as read-only to QEMU, as masking of MSI-X is
already in Xen now.
3. For registers that coexists inside the MSI-X table (this could be
only PBA I think), value read from physical page would be returned.

qemu-dm: fix unregister_iomem()
References: bnc#744014
This function (introduced quite a long time ago in
e7911109f4321e9ba0cc56a253b653600aa46bea - "disable qemu PCI
devices in HVM domains") appears to be completely broken, causing
the regression reported in
http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=1805 (due to
the newly added caller of it in
56d7747a3cf811910c4cf865e1ebcb8b82502005 - "qemu: clean up
MSI-X table handling"). It's unclear how the function can ever have
fulfilled its purpose: the value returned by iomem_index() is *not* an
index into mmio[].
Additionally, fix two problems:
- unregister_iomem() must not clear mmio[].start, otherwise
cpu_register_physical_memory() won't be able to re-use the previous
slot, thus causing a leak
- cpu_unregister_io_memory() must not check mmio[].size, otherwise it
won't properly clean up entries (temporarily) squashed through
unregister_iomem()

tools/libxc: send page-in requests in batches in linux_privcmd_map_foreign_bulk
One of the bottlenecks with foreign page-in request is the poor retry
handling in linux_privcmd_map_foreign_bulk(). It sends one request per
paged gfn at a time and it waits until the gfn is accessible. This
causes long delays in mmap requests from qemu-dm and xc_save.
Instead of sending one request at a time, walk the entire gfn list and
send batches of mmap requests. They will eventually end up in the pagers
request ring (if it has room again), and will fill up this ring so that
in turn the pager can also process page-in in batches.
