x86/mm: fix mod_l1_entry() return value when encountering r/o MMIO page
While putting together the workaround announced in
http://lists.xen.org/archives/html/xen-devel/2012-06/msg00709.html, I
found that mod_l1_entry(), upon encountering a set bit in
mmio_ro_ranges, would return 1 instead of 0 (the removal of the write
permission is supposed to be entirely transparent to the caller, even
more so to the calling guest).

svm: implement CR access part of DecodeAssist
Newer SVM implementations (Bulldozer) now give the used general
purpose register on a MOV-CR intercept explictly. This avoids
fetching and decoding the instruction from guest's memory and speeds
up some Windows guest, which exercise CR8 quite often.

svm: implement instruction fetch part of DecodeAssist (on #PF/#NPF)
Newer SVM implementations (Bulldozer) copy up to 15 bytes from the
instruction stream into the VMCB when a #PF or #NPF exception is
intercepted. This patch makes use of this information if available.
This saves us from a) traversing the guest's page tables, b) mapping
the guest's memory and c) copy the instructions from there into the
hypervisor's address space.
This speeds up #NPF intercepts quite a lot and avoids cache and TLB
trashing.

HVM/SVM: enable tsc scaling ratio for SVM
Future AMD CPUs support TSC scaling. It allows guests to have a
different TSC frequency from host system using this formula: guest_tsc
= host_tsc * tsc_ratio + vmcb_offset. The tsc_ratio is a 64bit MSR
contains a fixed-point number in 8.32 format (8 bits for integer part
and 32bits for fractional part). For instance 0x00000003_80000000
means tsc_ratio=3.5.
This patch enables TSC scaling ratio for SVM. With it, guest VMs don't
need take #VMEXIT to calculate a translated TSC value when it is
running under TSC emulation mode. This can substancially reduce the
rdtsc overhead.

x86/amd: Eliminate cache flushing when entering C3 on select AMD processors
AMD Fam15h processors have a shared cache. It does not need
to be be flushed when entering C3 and doing so causes reduces
performance. Modify acpi_processor_power_init_bm_check to
prevent these processors from flushing when entering C3.

x86: consolidate cpu_core_id and phys_proc_id into cpuinfo_x86 struct
This patch moves cpu_core_id and phys_proc_id into cpuinfo_x86
structure. This is similar to upstream Linux kernel's approach.

x86: AMD core-pair topology detection code
This patch is to support core-pair topology introduced by AMD CPUs,
which introduces a new concept of [core, compute unit]. There is a new
feature bit for topology extension in CPUID:0x80000001. Also a new
CPUID 0x8000001E is introduced for CPU topology enumeration. This
patch collects the sibling information from the new CPUID and will be
stored in the sibling map in Xen hypervisor.

tools/pygrub: fix solaris kernel sniff
Solaris 11 build 163+ removes '/platform/i86xpv/kernel/unix' and only the
64-bit PV kernel file '/platform/i86xpv/kernel/amd64/unix' exists.
This patch fixes the detection.

x86: Remove timeouts from INIT-SIPI-SIPI sequence when using x2apic.
Some of the timeouts are pointless since they're waiting for the ICR
to ack the IPI delivery and that doesn't happen on x2apic.
The others should be benign (and are suggested in the SDM) but
removing them makes AP bringup much more reliable on some test boxes.

x86: update Intel CPUID masking code to latest spec
..., which adds masking of the xsave feature leaf.
Also fix the printing (to actually make it do what it was supposed to
do from the beginning) of what specific masking couldn't be done in
case the user requested something the hardware doesn't support.

xen: Infrastructure to allow irqs to share vector maps
Laying the groundwork for per-device vector maps. This generic
code allows any irq to point to a vector map; all irqs sharing the
same vector map will avoid sharing vectors.

x86: Fix up irq vector map logic
We need to make sure that cfg->used_vector is only cleared once;
otherwise there may be a race condition that allows the same vector to
be assigned twice, defeating the whole purpose of the map.
This makes two changes:
* __clear_irq_vector() only clears the vector if the irq is not being
moved
* smp_iqr_move_cleanup_interrupt() only clears used_vector if this
is the last place it's being used (move_cleanup_count==0 after
decrement).
Also make use of asserts more consistent, to catch this kind of logic
bug in the future.

xen: Option to allow per-device vector maps for MSI IRQs
Add a vector-map to pci_dev, and add an option to point MSI-related
IRQs to the vector-map of the device.
This prevents irqs from the same device from being assigned
the same vector on different pcpus. This is required for systems
using an AMD IOMMU, since the intremap tables on AMD only look at
vector, and not destination ID.

xen: Add global irq_vector_map option, set if using AMD global intremap tables
As mentioned in previous changesets, AMD IOMMU interrupt
remapping tables only look at the vector, not the destination
id of an interrupt. This means that all IRQs going through
the same interrupt remapping table need to *not* share vectors.
The irq "vector map" functionality was originally introduced
after a patch which disabled global AMD IOMMUs entirely. That
patch has since been reverted, meaning that AMD intremap tables
can either be per-device or global.
This patch therefore introduces a global irq vector map option,
and enables it if we're using an AMD IOMMU with a global
interrupt remapping table.
This patch removes the "irq-perdev-vector-map" boolean
command-line optino and replaces it with "irq_vector_map",
which can have one of three values: none, global, or per-device.
Setting the irq_vector_map to any value will override the
default that the AMD code sets.

x86: work around certain Intel BIOSes causing (transient) hangs during boot
They apparently leave the USB legacy emulation bits set in ICH10's
SMI Control and Enable register, but fail to handle the resulting SMIs
gracefully. The hangs can apparently extend indefinitely, but are
commonly observed to last between a few seconds and a minute.
This assumes that only ICH10-based systems on Intel main boards with
Intel BIOS may be affected. Until Intel comes up with a more precise
identification of affected BIOSes, all Intel ones on Intel boards
will get this workaround applied.

Fix PV CPUID virtualization of XSave
The patch will fix XSave CPUID virtualization for PV guests. The XSave
area size returned by CPUID leaf D is changed dynamically depending on
the XCR0. Tools/libxc only assigns a static value. The fix will adjust
xsave area size during runtime.
Note: This fix is already in HVM cpuid virtualization. And Dom0 is not
affected, either.

introduce xzalloc() & Co
Rather than having to match a call to one of the xmalloc() flavors with
a subsequent memset(), introduce a zeroing variant of each of those
flavors.

x86/AMD: Do not enable ARAT feature on AMD processors below family 0x12
Determining whether an AMD processor is affected by erratum 400 may
have some corner cases and handling these cases is somewhat complicated.
In the interest of simplicity we won't claim ARAT support on processor
families below 0x12.

Hypercall continuation cancelation in compat mode for XENMEM_get/set_pod_target
If copy_to_guest failed in the compat code after a continuation as been
done in the native code we need to cancel it so we won't reexecute the

x86/IO-APIC: refine EOI-ing of migrating level interrupts
Rather than going through all IO-APICs and calling io_apic_eoi_vector()
for the vector in question, just use eoi_IO_APIC_irq().
This in turn allows to eliminate quite a bit of other code.

x86/IRQ: prevent vector sharing within IO-APICs
Following the prevention of vector sharing for MSIs, this change
enforces the same within IO-APICs: Pin based interrupts use the IO-APIC
as their identifying device under the AMD IOMMU (and just like for
MSIs, only the identifying device is used to remap interrupts here,
with no regard to an interrupt's destination).
Additionally, LAPIC initiated EOIs (for level triggered interrupts) too
use only the vector for identifying which interrupts to end. While this
generally causes no significant problem (at worst an interrupt would be
re-raised without a new interrupt event actually having occurred), it
still seems better to avoid the situation.
For this second aspect, a distinction is being made between the
traditional and the directed-EOI cases: In the former, vectors should
not be shared throughout all IO-APICs in the system, while in the
latter case only individual IO-APICs need to be contrained (or, if the
firmware indicates so, sub- groups of them having the same GSI appear
at multiple pins).

x86/xsave: provide guests with finit-like environment
Without the use of xsave, guests get their initial floating point
environment set up with finit. At least NetWare actually depends on
this (in particular on all exceptions being masked), so to be
consistent set the same environment also when using xsave. This is
also in line with all SSE exceptions getting masked initially.
To avoid further fragile casts in xstate_alloc_save_area() the patch
also changes xsave_struct's fpu_see member to have actually usable
fields.
The patch was tested in its technically identical, but modified-file-
wise different 4.1.2 version.

x86/vioapic: clear remote IRR when switching RTE to edge triggered mode
Xen itself (as much as Linux) relies on this behavior, so it should
also emulate it properly. Not doing so reportedly gets in the way of
kexec inside a HVM guest.

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).

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.

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.

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.

X86: Add a delay between INIT & SIPIs for tboot AP bring-up in X2APIC case
Without this delay, Xen could not bring APs up while working with
TXT/tboot, because tboot needs some time in APs to handle INIT before
becoming ready for receiving SIPIs (this delay was removed as part of
c/s 23724 by Tim Deegan).
