17a4ed8a5e bitops: drop volatile qualifier
Qualifier 'volatile' is not useful for applications, it's too strict
for single threaded code but does not give the real atomicity guarantees
needed for multithreaded code.

Drop them and now useless casts.

69deef089d configure: Don't run Xen compile checks in subshells
The Xen compile checks are currently run inside subshells. This
is unnecessary and has the effect that if do_cc() exits with
an error message then this only causes the subshell to exit,
not the whole of configure, which is confusing. Remove the

ee785fed5d Fixes related to processing of qemu's -numa option
The -numa option to qemu is used to create [fake] numa nodes
and expose them to the guest OS instance.

There are a couple of issues with the -numa option:

a) Max VCPU's that can be specified for a guest while using
   the qemu's -numa option is 64. Due to a typecasting issue
   when the number of VCPUs is > 32 the VCPUs don't show up
   under the specified [fake] numa nodes.

b) KVM currently has support for 160VCPUs per guest. The
   qemu's -numa option has only support for upto 64VCPUs
   per guest.
This patch addresses these two issues.

Below are examples of (a) and (b)

a) >32 VCPUs are specified with the -numa option:

0f66998ff6 vnc: disable VNC password authentication (security type 2) when in FIPS mode
FIPS 140-2 requires disabling certain ciphers, including DES, which is used
by VNC to obscure passwords when they are sent over the network.  The
solution for FIPS users is to disable the use of VNC password auth when the
host system is operating in FIPS compliance mode and the user has specified
'-enable-fips' on the QEMU command line.

This patch causes QEMU to emit a message to stderr when the host system is
running in FIPS mode and a VNC password was specified on the commend line.
If the system is not running in FIPS mode, or is running in FIPS mode but
VNC password authentication was not requested, QEMU operates normally.

Remove an out of date comment: this comment used to be attached to

It is in any case obsolete since (a) the function arguments it refers
to have been replaced with a single MemoryRegionSection* argument and
(b) the inability to handle regions whose offset_within_address_space
and offset_within_region aren't equally aligned was fixed as part of
the rewrite of this code.

69b67646bc exec.c: Use subpages for large unaligned mappings
Registering a multi-page memory region that is non-page-aligned results
in a subpage from the start to the page boundary, some number of full
pages, and possibly another subpage from the last page boundary to the
end. The full pages will have a value for offset_within_region that is
not a multiple of TARGET_PAGE_SIZE. Accesses through softmmu are unable
to handle this and will segfault.

Handling full pages through subpages is not optimal, but only
non-page-aligned mappings take the penalty.

subpage_register() expects "end" to be the last byte in the mapping.
Registering a non-page-aligned memory region that extends up to or
beyond a page boundary causes subpage_register() to silently fail
through the (end >= PAGE_SIZE) check.

This bug does not cause noticeable problems for mappings that do not
extend to a page boundary, though they do register an extra byte.

76b523db00 megasas: static SAS addresses
This patch introduces a new property 'sas_address' which
allows the user to specify the SAS address for the HBA.
The default address is following the NAA locally assigned
identifier format with the locally assigned address
0x525400 as used eg for the MAC addresses.
The lower bytes are set to the pci address which
will ensure uniqueness for the local machine.

The port addresses are now calculated based on the magic
number 0x1221 (which is found in real hardware, too) plus
the device number.

c8057f951d Support 'help' as a synonym for '?' in command line options
For command line options which permit '?' meaning 'please list the
permitted values', add support for 'help' as a synonym, by abstracting
the check out into a helper function.

This change means that in some cases where we were being lazy in
our string parsing, "?junk" will now be rejected as an invalid option
rather than being (undocumentedly) treated the same way as "?".

Update the documentation to use 'help' rather than '?', since '?'
is a shell metacharacter and thus prone to fail confusingly if there
is a single character filename in the current working directory and
the '?' has not been escaped. It's therefore better to steer users
towards 'help', though '?' is retained for backwards compatibility.

We do not, however, update the output of the system emulator's -help
(or any documentation autogenerated from the qemu-options.hx which
is the source of the -help text) because libvirt parses our -help
output and will break. At a later date when QEMU provides a better
interface so libvirt can avoid having to do this, we can update the
-help text too.

bcba2a72ed cpu: Move CPU_COMMON_THREAD into CPUState
CPU_COMMON_THREAD was only used for Windows, adding an hThread field
to CPU_COMMON.

Move the field into QOM CPUState and change its type to HANDLE,
which it is assigned from. This requires Windows headers, pulled in
through qemu-thread.h.

02d2bd5d57 Replace 'struct siginfo' with 'siginfo_t'.
glibc 2.16 will remove the undocumented definition of 'struct siginfo'
from <bits/siginfo.h>.

This change is already present in glibc 2.15.90, so qemu compilation
of certain targets (eg. cris-user) breaks.

This struct was always typedef'd to be the same as 'siginfo_t' which
is what POSIX documents, so use that instead.

65dee38052 target-i386: move cpu_reset and reset callback to cpu.c
Moving reset callback into cpu object from board level and
resetting cpu at the end of x86_cpu_realize() will allow properly
create cpu object during run-time (hotplug) without calling reset externaly.

When reset over QOM hierarchy is implemented, reset callback
should be removed.

v2:
  - leave cpu_reset in pc_new_cpu() for now, it's to be cleaned up when APIC
    init is moved in cpu.c

dd673288a8 target-i386: move cpu halted decision into x86_cpu_reset
MP initialization protocol differs between cpu families, and for P6 and
onward models it is up to CPU to decide if it will be BSP using this
protocol, so try to model this. However there is no point in implementing
MP initialization protocol in qemu. Thus first CPU is always marked as BSP.

This patch:
 - moves decision to designate BSP from board into cpu, making cpu
self-sufficient in this regard. Later it will allow to cleanup hw/pc.c
and remove cpu_reset and wrappers from there.
 - stores flag that CPU is BSP in IA32_APIC_BASE to model behavior
described in Inted SDM vol 3a part 1 chapter 8.4.1
 - uses MSR_IA32_APICBASE_BSP flag in apic_base for checking if cpu is BSP

patch is based on Jan Kiszka's proposal:

f6ccf1f453 configure: Fix xen probe with Xen 4.2 and later
The xs.h header is now deprecated and produces a warning. This prevents the
configure script from enabling Xen with xen-unstable whom will become 4.2. As
this header is not anymore common to every version of Xen, we just remove it
from the early probe for Xen.
