memory: fix limiting of translation at a page boundary
Commit
360e607 (address_space_translate: do not cross page boundaries,
2014-01-30) broke MMIO accesses in cases where the section is shorter
than the full register width. This can happen for example with the
Bochs DISPI registers, which are 16 bits wide but have only a 1-byte
long MemoryRegion (if you write to the "second byte" of the register
your access is discarded; it doesn't write only to half of the register).
Restrict the action of commit
360e607 to direct RAM accesses. This
is enough for Xen, since MMIO will not go through the mapcache.

arm_gic: Fix GIC pending behavior
The existing implementation of the pending behavior in gic_set_irq,
gic_complete_irq, and the distributor pending set/clear registers does
not follow the semantics of the GICv2.0 specs, but may implement the
11MPCore support. Therefore, maintain the existing semantics for
11MPCore and v7M NVIC and change the behavior to be in accordance with
the GICv2.0 specs for "generic implementations" (s->revision == 1 ||
s->revision == 2).
Generic implementations distinguish between setting a level-triggered
interrupt pending through writes to the GICD_ISPENDR and when hardware
raises the interrupt line. Writing to the GICD_ICPENDR will not cause
the interrupt to become non-pending if the line is still active, and
conversely, if the line is deactivated but the interrupt is marked as
pending through a write to GICD_ISPENDR, the interrupt remains pending.
Handle this situation in the GIC_TEST_PENDING (which now becomes a
static inline named gic_test_pending) and let the 'pending' field
correspond only to the latched state of the D-flip flop in the GICv2.0
specs Figure 4-10.
The following changes are added:
gic_test_pending:
Make this a static inline and split out the 11MPCore from the generic
behavior. For the generic behavior, consider interrupts pending if:
((s->irq_state[irq].pending & (cm) != 0) ||
(!GIC_TEST_EDGE_TRIGGER(irq) && GIC_TEST_LEVEL(irq, cm))
gic_set_irq:
Split out the 11MPCore from the generic behavior. For the generic
behavior, always GIC_SET_LEVEL() on positive level, but only
GIC_SET_PENDING for edge-triggered interrupts and always simply
GIC_CLEAR_LEVEL() on negative level.
gic_complete_irq:
Only resample the line for line-triggered interrupts on an 11MPCore.
Generic implementations will sample the line directly in
gic_test_pending().

qtest: unlink UNIX domain sockets after connecting
UNIX domain sockets are leaked when tests call abort(3) (indirectly via

Unlink the files immediately after the connection has been established

qtest: unlink QEMU pid file after startup
After starting the QEMU process and initializing the QMP connection, we
can read the pid file and unlink it.
Just stash away the pid instead of the pid filename. This way we can
avoid pid file leaks since running tests may abort(3) without cleanup.

Update seabios submodule to 1.7.4
Not that many changes as we already have a git snapshot pretty close
to final 1.7.4 in the tree. Most notably change is the vgabios change
which fixes the windows guest regression.
Full git shortlog:
Gerd Hoffmann (2):
run qemu_cfg_e820 only for CONFIG_QEMU=y
change boot order load log level
Kevin O'Connor (10):
Minor - move sgdt/lgdt macros from stacks.c to x86.h.
Separate out sec32init sections even when not doing code relocation.
floppy: Fix incorrect LBA to CHS translation.
floppy: Fix accesses to DOR register.
vgabios: Avoid memory references via %esp register in vgabios.
Small improvements to irqentry_extrastack assembler.
floppy: Encode command and flags into single value in floppy pio code.
On disk format request, verify cylinders and pass to driver.
floppy: Implement cylinder seeking when accessing a different cylinder.
coreboot: Make sure to print the SeaBIOS version in cbmem debug output.

roms: remove explicit MAKEFLAGS from recursive make invocations
When using $(MAKE) within a makefile, we shouldn't be explicitly
including $(MAKEFLAGS) on the command-line. It causes problems
when that makefile is recursively invoked. When the roms/Makefile
is invoked as in make -C roms bios a spurious 'w' appears on the
sub-make invocation, due to the erroneous $(MAKEFLAGS) inclusion.

linux-user: Fix trampoline code for CRIS
__put_user can write bytes, words (2 bytes) or longwords (4 bytes).
Here obviously words should have been written, but bytes were written,
so values like 0x9c5f were truncated to 0x5f.
Fix this by changing retcode from uint8_t to to uint16_t in
target_signal_frame and also in the unused rt_signal_frame.
This problem was reported by static code analysis (smatch).

Without this we occasionally trigger an assert at
hw/pci/pci.c:pcibus_reset that asserts the irq_count is zero on reset.
This has become a problem with the new drm driver for linux, since doing

irq and the reset assertion that the irq is clear.
