ff4873cb8c coroutine-win32.c: Add noinline attribute to work around gcc bug
A gcc codegen bug in x86_64-w64-mingw32-gcc (GCC) 4.6.3 means that
non-debug builds of QEMU for Windows tend to assert when using
coroutines. Work around this by marking qemu_coroutine_switch
as noinline.

If we allow gcc to inline qemu_coroutine_switch into
coroutine_trampoline, then it hoists the code to get the
address of the TLS variable "current" out of the while() loop.
This is an invalid transformation because the SwitchToFiber()
call may be called when running thread A but return in thread B,
and so we might be in a different thread context each time
round the loop. This can happen quite often.  Typically.
a coroutine is started when a VCPU thread does bdrv_aio_readv:

     VCPU thread

     main VCPU thread coroutine      I/O coroutine
        bdrv_aio_readv ----->
                                     start I/O operation
                                       thread_pool_submit_co
                       <------------ yields
        back to emulation

Then I/O finishes and the thread-pool.c event notifier triggers in
the I/O thread.  event_notifier_ready calls thread_pool_co_cb, and
the I/O coroutine now restarts *in another thread*:

     iothread

     main iothread coroutine         I/O coroutine (formerly in VCPU thread)
        event_notifier_ready
          thread_pool_co_cb ----->   current = I/O coroutine;
                                     call AIO callback

But on Win32, because of the bug, the "current" being set here the
current coroutine of the VCPU thread, not the iothread.

noinline is a good-enough workaround, and quite unlikely to break in
the future.

(Thanks to Paolo Bonzini for assistance in diagnosing the problem
and providing the detailed example/ascii art quoted above.)

303752a906 target-i386: Support "invariant tsc" flag
Expose "Invariant TSC" flag, if KVM is enabled. From Intel documentation:

17.13.1 Invariant TSC The time stamp counter in newer processors may
support an enhancement, referred to as invariant TSC. Processor’s
support for invariant TSC is indicated by CPUID.80000007H:EDX[8].
The invariant TSC will run at a constant rate in all ACPI P-, C-.
and T-states. This is the architectural behavior moving forward. On
processors with invariant TSC support, the OS may use the TSC for wall
clock timer services (instead of ACPI or HPET timers). TSC reads are
much more efficient and do not incur the overhead associated with a ring
transition or access to a platform resource.

68bfd0ad4a target-i386: block migration and savevm if invariant tsc is exposed
Invariant TSC documentation mentions that "invariant TSC will run at a
constant rate in all ACPI P-, C-. and T-states".

This is not the case if migration to a host with different TSC frequency
is allowed, or if savevm is performed. So block migration/savevm.

120eee7d1f target-i386: Set migratable=yes by default on "host" CPU mooel
Having only migratable flags reported by default on the "host" CPU model
is safer for the following reasons:

 * Existing users may expect "-cpu host" to be migration-safe, if they
   take care of always using compatible host CPUs, host kernels, and
   QEMU versions.
 * Users who don't care aboug migration and want to enable all features
   supported by the host kernel can simply change their setup to use
   migratable=no.

Without this change, people using "-cpu host" will stop being able to
migrate, because now "invtsc" is getting enabled by default.

We are not setting migratable=yes by default on all X86CPU subclasses,
because users should be able to get non-migratable features enabled if
they ask for them explicitly.

84f1b92f97 target-i386: Add "migratable" property to "host" CPU model
This flag will allow the user to choose between two modes:
 * All flags that can be enabled on the host, even if unmigratable
   (migratable=no);
 * All flags that can be enabled on the host, are known to QEMU
   and migratable (migratable=yes).

The default is still migratable=false, to keep current behavior, but
this will be changed to migratable=true by another patch.

My plan was to support the "migratable" flag on all CPU classes, but
have the default to "false" on all CPU models except "host". However,
DeviceClass has no mechanism to allow a child class to have a different
property default from the parent class yet, so by now only the "host"
CPU model will support the "migratable" flag.

136a7e9a85 target-i386: kvm: Don't enable MONITOR by default on any CPU model
KVM never supported the MONITOR flag so it doesn't make sense to have it
enabled by default when KVM is enabled.

The rationale here is similar to the cases where it makes sense to have
a feature enabled by default on all CPU models when on KVM mode (e.g.
x2apic). In this case we are having a feature disabled by default for
the same reasons.

In this case we don't need machine-type compat code because it is
currently impossible to run a KVM VM with the MONITOR flag set.

Grub first opens a session to the TFTP server for every initrd file and
retrieves only the file size for all.
Then it wants to download the content using the old sessions which are
already expired.

Increasing the maximum number of session of the internal TFTP

0211b5cf2d target-ppc: Fix compiler warning
gcc reports a warning which is usually wrong:

target-ppc/dfp_helper.c: In function ‘dfp_get_digit’:
target-ppc/dfp_helper.c:417:1: warning:
 control reaches end of non-void function [-Wreturn-type]

The compiler shows the warning if assert is not marked with the noreturn
attribute or if the code is compiled with -DNDEBUG.

Using g_assert_not_reached better documents the intention and does not
have these problems.

e91c793cb5 configure: Enable TPM by default, add --disable-tpm
I don't see why tpm is disabled by default: it doesn't have any
external dependencies, or change default behavior. Leaving it disabled
is just going to cause it to bit rot.

Enable it by default, and add a --disable-tpm option.
