target-i386: Enabling IA32_TSC_ADJUST for QEMU KVM guest VMs
CPUID.7.0.EBX[1]=1 indicates IA32_TSC_ADJUST MSR 0x3b is supported
Basic design is to emulate the MSR by allowing reads and writes to the
hypervisor vcpu specific locations to store the value of the emulated MSRs.
In this way the IA32_TSC_ADJUST value will be included in all reads to
the TSC MSR whether through rdmsr or rdtsc.
As this is a new MSR that the guest may access and modify its value needs
to be migrated along with the other MRSs. The changes here are specifically
for recognizing when IA32_TSC_ADJUST is enabled in CPUID and code added
for migrating its value.

migration: Fix madvise breakage if host and guest have different page sizes
madvise(DONTNEED) will throw away the contents of the whole page at the
given address, even if the given length is less than the page size. One
can argue about whether that's the correct behaviour, but that's what it's
done for a long time in Linux at least.
That means that the madvise() in ram_load(), on a setup where
TARGET_PAGE_SIZE is smaller than the host page size, can throw away data
in guest pages adjacent to the one it's actually processing right now,
leading to guest memory corruption on an incoming migration.
This patch therefore, disables the madvise() if the host page size is
larger than TARGET_PAGE_SIZE. This means we don't get the benefits of that
madvise() in this case, but a more complete fix is more difficult to
accomplish. This at least fixes the guest memory corruption.

blkdebug: Implement suspend/resume of AIO requests
This allows more systematic AIO testing. The patch adds three new
operations to blkdebug:
* Setting a "breakpoint" on a blkdebug event. The next request that
triggers this breakpoint is suspended and is tagged with a name.
The breakpoint is removed after a request has triggered it.
* A suspended request (identified by it's tag) can be resumed
* It's possible to check whether a suspended request with a given
tag exists. This can be used for waiting for an event.
Ideally, we would instead tag requests right when they are created and
set breakpoints for individual requests. However, at this point the
block layer doesn't allow this easily, and breakpoints that trigger for
any request already allow a lot of useful testing.

Support default block interfaces per QEMUMachine
There are QEMUMachines that have neither IF_IDE nor IF_SCSI as a
default/standard interface to their block devices / drives. Therefore,
this patch introduces a new field default_block_type per QEMUMachine
struct. The prior use_scsi field becomes thereby obsolete and is
replaced through .default_block_type = IF_SCSI.
This patch also changes the default for s390x to IF_VIRTIO and
removes an early hack that converts IF_IDE drives.
Other parties have already claimed interest (e.g. IF_SD for exynos)
To create a sane default, for machines that dont specify a
default_block_type, this patch makes IF_IDE = 0 and IF_NONE = 1.
I checked all users of IF_NONE (blockdev.c and ww/device-hotplug.c)
as well as IF_IDE and it seems that it is ok to change the defines -
in other words, I found no obvious (to me) assumption in the code
regarding IF_NONE==0. IF_NONE is only set if there is an
explicit if=none. Without if=* the interface becomes IF_DEFAULT.
I would suggest to have some additional care, e.g. by letting
this patch sit some days in the block tree.

block: vpc support for ~2 TB disks
The VHD specification allows for up to a 2 TB disk size. The current
implementation in qemu emulates EIDE and ATA-2 hardware which only allows
for up to 127 GB. This disk size limitation can be overridden by allowing
up to 255 heads instead of the normal 4 bit limitation of 16. Doing so
allows disk images to be created of up to nearly 2 TB. This change does
not violate the VHD format specification nor does it change how smaller
disks (ie, <=127GB) are defined.
[Charles Arnold also writes: "In analyzing a 160 GB VHD fixed disk image
created on Windows 2008 R2, it appears that MS is also ignoring the CHS

obviously doesn't represent an image size of 160 GB." -- Stefan]

defined in two places. First, it's defined from the

virtio-pci, just two lines above the call to that macro.

Default to 'cc' as our compiler, rather than 'gcc'. We used to have
to insist on gcc when we still kept the CPU env in a fixed global

on clang as well as gcc. Using 'cc' should generally result in us
using the most standard and maintained system compiler for the
platform. (For instance on newer MacOS X 'gcc' exists but is an
elderly compiler provided mostly for legacy reasons, and 'cc'
(which is clang) is definitely the better choice.) On Linux there
will generally be no user-visible change since cc will be gcc.
This changeover necessitates a slight reworking of how we set the

arm: a9mpcore: remove un-used ptimer_iomem field
I'm guessing this is a hangover from a previous coreification of the mptimer
