event notifier: Fix setup for win32
The event notifier state is only reset by test_and_clear. But we created
the windows event object with auto-reset, which subtly swallowed events.

build: compile translate.o with -fno-gcse option on GCC 4.6.x and 4.7.[012]
These versions of GCC require insane (>2GB) amounts of memory to compile
translate.o. As a countermeasure, disable the culprit optimization pass.
This should fix the buildbot failure for default_x86_64_fedora16. Anyway
this is a good thing to do because people will try to compile 1.3 with
less than 2GB of memory and complain.

virtio-scsi: Fix subtle (guest) endian bug
The virtio-scsi config space is, by specification, in guest endian (which
is ill-defined, but there you go). In virtio_scsi_get_config() we set up
all the fields in there, using stl_raw(). Which is a problem for the
max_channel and max_target fields, which are 16-bit, not 32-bit. For
little-endian targets we get away with it by accident, since the first
two bytes will still be correct, and the extra two bytes written (with
zeroes) will be overwritten correctly by the next store.
But for big-endian guests, this means the max_target field ends up as zero,
which means the guest will only recognize a single disk on the virtio-scsi
bus. This patch fixes the problem.

virtio-scsi: Fix some endian bugs with virtio-scsi
The virtio-scsi specification does not specify the correct endianness for
fields in the request structure. It's therefore best to assume that it is
"guest native" endian since that's the (stupid and poorly defined) norm in
virtio.
However, the qemu device for virtio-scsi has no byteswaps at all, and so
will break if the guest has different endianness from the host. This patch
fixes it by adding tswap() calls for the sense_len and resid fields in
the request structure. In theory status_qualifier needs swaps as well,
but that field is never actually touched. The tag field is a uint64_t, but
since its value is completely arbitrary, it might as well be uint8_t[8]
and so it does not need swapping.

iscsi: fix deadlock during login
If the connection is interrupted before the first login is successfully
completed qemu-kvm is waiting forever in qemu_aio_wait().
This is fixed by performing an sync login to the target. If the
connection breaks after the first successful login errors are
handled internally by libiscsi.

nbd-server-add: Fix the default for 'writable'
The documentation to this monitor command tells, that 'writable'
argument is optional and defaults to false. However, the code sets
true as the default. But since some applications may already been
using this, it's safer to fix the code and not documentation which
would break those applications.

rtc: Only call rtc_set_cmos when Register B SET flag is disabled.
This bug occurs when the SET flag of Register B is enabled. When an RTC
data register (i.e. any of the ten time/calender CMOS bytes) is set, the
data is (as expected) correctly stored in the cmos_data array. However,
since the SET flag is enabled, the function rtc_set_time is not invoked.
As a result, the field base_rtc in RTCState remains uninitialized. This
causes a problem on subsequent writes which can end up overwriting data.
To see this, consider writing data to Register A after having written
data to any of the RTC data registers; the following figure illustrates
the call stack for the Register A write operation:
+- cmos_io_port_write
+-- check_update_timer
+---- get_next_alarm
+------ rtc_update_time
In rtc_update_time, get_guest_rtc calculates the wrong time and
overwrites the previously written RTC data register values.

version required to build QEMU (we only require 2.16 to run tests,
since that is the first version including GTester). Do not use it

The cancellation test is failing on the buildbots. While the failure
merits a little more investigation to understand what is going on,
the logs show that the failure is not impacting the coverage
provided by the test. Hence, loosen a bit the assertions in a
way that should let the test proceed and hopefully pass.

The global variable 'ram_size' is hidden by the local variable
declaration in s390_init(). Since we want to update the global
ram size in certain cases we must not use a local ram_size
variable.
- This fixes booting with unusual ram sizes like -m 67001

vl.c: Fix broken -usb option
Commit 094b287f0b accidentally broke the "-usb" command line
option, so it would have no effect if the user had not specified
any machine options at that point. (the return value from
'qemu_opts_find(qemu_find_opts("machine"), 0);' is NULL if there
are no user specified options, so it is only to be used for
looking up an option, not when trying to set one.) Similarly,
would '-usbdevice' no longer cause USB to default to enabled.
Fix this regression by using the same style of code for forcing
the usb=on machine option that we use for other aliases such as
'-enable-kvm'.

kvm: fix incorrect length in a loop over kvm dirty pages map
QEMU allocates a map enough for 4k pages. However the system page size
can be 64K (for example on POWER) and the host kernel uses only a small
part of it as one big stores a dirty flag for 16 pages 4K each,
the hpratio variable stores this ratio and
the kvm_get_dirty_pages_log_range function handles it correctly.
However kvm_get_dirty_pages_log_range still goes beyond the data
provided by the host kernel which is not correct. It does not cause
errors at the moment as the whole bitmap is zeroed before doing KVM ioctl.
The patch reduces number of iterations over the map.

PPC: Fix missing TRACE exception
This patch fixes bug 1031698 :
https://bugs.launchpad.net/qemu/+bug/1031698
If we look at the (truncated) translation of the conditional branch
instruction in the test submitted in the bug post, the call to the
exception helper is missing in the "bne-false" chunk of translated
code :
IN:
bne- 0x1800278
OUT:
0xb544236d: jne 0xb5442396
0xb5442373: mov %ebp,(%esp)
0xb5442376: mov $0x44,%ebx
0xb544237b: mov %ebx,0x4(%esp)
0xb544237f: mov $0x1800278,%ebx
0xb5442384: mov %ebx,0x25c(%ebp)
0xb544238a: call 0x827475a
^^^^^^^^^^^^^^^^^^
0xb5442396: mov %ebp,(%esp)
0xb5442399: mov $0x44,%ebx
0xb544239e: mov %ebx,0x4(%esp)
0xb54423a2: mov $0x1800270,%ebx
0xb54423a7: mov %ebx,0x25c(%ebp)
Indeed, gen_exception(ctx, excp) called by gen_goto_tb (called by
gen_bcond) changes ctx->exception's value to excp's :
gen_bcond()
{
gen_goto_tb(ctx, 0, ctx->nip + li - 4);
/* ctx->exception value is POWERPC_EXCP_BRANCH */
gen_goto_tb(ctx, 1, ctx->nip);
/* ctx->exception now value is POWERPC_EXCP_TRACE */
}
Making the following gen_goto_tb()'s test false during the second call :
if ((ctx->singlestep_enabled &
(CPU_BRANCH_STEP | CPU_SINGLE_STEP)) &&
ctx->exception == POWERPC_EXCP_BRANCH /* false...*/) {
target_ulong tmp = ctx->nip;
ctx->nip = dest;
/* ... and this is the missing call */
gen_exception(ctx, POWERPC_EXCP_TRACE);
ctx->nip = tmp;
}
So the patch simply adds the missing matching case, fixing our problem.

hw/ide/macio: Fix segfault caused by NULL DMAContext*
Pass qemu_sglist_init the global dma_context_memory rather than a NULL
pointer; this fixes a segfault in dma_memory_map() when the guest
starts using DMA.

target-i386: Enable SSSE3 TCG support
SSSE3 support has been added to TCG more than 4 years ago in commit
4242b1bd8acc19aaaacffdaad4ac23213d72a72b. It has been disabled by
mistake in commit 551a2dec8fa55006a68393b9d6fb63577d2b3f1c.

target-i386/cpu: Add missing flags to Haswell CPU model
When adding the Haswell CPU model, I intended to make it a superset of the
features present on the SandyBridge model, but I have removed the SEP and
RDTSCP features from the feature list by mistake. This patch adds the
missing SEP and RDTSCP features (that are present on SandyBridge) to
Haswell.
