ecba19935a hw/timer: Revert "hpet: inverse polarity when pin above ISA_NUM_IRQS"
This reverts commit 0d63b2dd31.

This change was originally intended to correct the HPET behavior
in conjunction with Linux, however the behavior that it actually creates
is not compatible with the ioapic.c implementation; it used to be
compatible with KVM's own IOAPIC but it is not anymore.

089adafdc6 ps2kbd: default to scancode_set 2, as with KBD_CMD_RESET
This line has been added in commit ef74679a81 with
other initializations. However, scancode set 0 doesn't exist (only 1, 2, 3).
This works well as long as operating system is resetting keyboard, or overwriting
the current scancode set with the one it wants.

This fixes IBM 40p firmware, which doesn't bother sending KBD_CMD_RESET or KBD_CMD_SCANCODE.

3ccdbecf80 tci: Fix build regression
Commit d38ea87ac5 cleaned the include
statements which resulted in a wrong order of assert.h and the definition
of NDEBUG in tci.c. Normally NDEBUG modifies the definition of the assert
macro, but here this definition comes too late which results in a failing
build.

To fix this, a new macro tci_assert which depends on CONFIG_DEBUG_TCG
is introduced. Only builds with CONFIG_DEBUG_TCG will use assertions.
Even in this case, it is still possible to disable assertions by
defining NDEBUG via compiler settings.

a3973f551d tests/bios-tables-test: fix assert
Newer iasl does not add the aml file name to the Definition Block.
See acpica tools commit  1ecbb3d5:
  "Emit the AMLFilename as a zero-length string. Allows the compiler to create
   the name later -- making it easier to rename the parent ASL (DSL) file."

That causes an assert in acpi tests:
   tests/bios-tables-test.c:455:normalize_asl: assertion failed: (block_name)

Fix it by striping the start of the definition block line until the first comma.
The block name is always the first parameter and
the grammar does not allow comma in between, so it is safe.

fecb48f744 virtio-balloon: reset the statistic timer to load device
If before loading snapshot we had set the timer of statistics, then after
applying snapshot the expiry time would be irrelevant for the restored
state of the virtual clocks. A simple fix is just to restart the timer
after loading snapshot.

For the user it may look like a long delay of statistics update after switch
to the snapshot.

3d100d0fa9 Migration: Add i82801b11 migration data
The i82801b11 bridge didn't have a vmsd and thus didn't send
any migration data, including that of its parent PCIBridge object.
The symptom being if the guest used any devices behind the bridge
the guest crashed (mostly with various interrupt related issues).

Note: This will cause migration from old qemus that used this device to
explicitly fail during migration as opposed to the guest crashing.

bab47d9a75 Sort the fw_cfg file list
Entries are inserted in filename order instead of being
appended to the end in case sorting is enabled.

This will avoid any future issues of moving the file creation
around, it doesn't matter what order they are created now,
the will always be in filename order.

Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

Added machine type handling for compatibility.  This was
a fairly complex change, this will preserve the order of fw_cfg
for older versions no matter what order the firmware files
actually come in.  A list is kept of the correct legacy order
and the entries will be inserted based upon their order in
the list.  Except that some entries are ordered (in a specific
area of the list) based upon what order they appear on the
command line.  Special handling is added for those entries.

27559c214d qga: Workaround for console redirection from non-interactive qemu-ga service
mingw-glib uses helper process to assist gspawn() api. There are two
versions of helpers, one with main() and another with WinMain() startup
routines.

Whenever gspawn() detects consoleless environment (and qemu-ga is running
in such environment as Win32 service), it chooses helper with main()
instead of WinMain. It is done by name, e.g.
gspawn-win32-helper-console.exe vs gspawn-win32-helper.exe

Running console-aware application like any win32 console apps from main()
crt initalized process results in redirection of stdout to console created
in crt startup instead of parent-provided handle connected to subprocess
pipe. Thus, stdout/stderr redirection do not work correctly.

The patch makes WinMain()'s version of helper be used as the only helper
shipped with qemu-ga package. Using only win32 helper ensures console
is created before any redirection and fixes stdout/stderr redirection
issue.

e0a039e50d filter-buffer: fix segfault when starting qemu with status=off property
After commit 338d3f, we support 'status' property for filter object.
The segfault can be triggered by starting qemu with 'status=off' property
for filter, when the s->incoming_queue is NULL, we reference it directly
in qemu_net_queue_flush() which was called in status_changed() callback
function.

We shouldn't trigger status_changed() before the filter was initialized,
We can check the value of 'nf->netdev' to confirm if the filter is
initialized or not, so let's check its value before calling
status_changed().

91731d5f6d rtl8139: using CP_TX_OWN for ownership transferring during tx
Through CP_TX_OWN and CP_RX_OWN points to the same bit, we'd better use
CP_TX_OWN for tx descriptor handling.

2dc7553d0c tcg/mips: Fix type of tcg_target_reg_alloc_order[]
The MIPS TCG backend is the only one to have
tcg_target_reg_alloc_order[] elements of type TCGReg rather than int.
This resulted in commit 91478cefaa ("tcg: Allocate indirect_base
temporaries in a different order") breaking the build on MIPS since the
type differed from indirect_reg_alloc_order[]:

tcg/tcg.c:1725:44: error: pointer type mismatch in conditional expression [-Werror]
     order = rev ? indirect_reg_alloc_order : tcg_target_reg_alloc_order;
                                            ^

Make it an array of ints to fix the build and match other architectures.

95c3df5a24 crypto: Avoid memory leak on failure
Commit 7836857 introduced a memory leak due to invalid use of
Error vs. visit_type_end().  If visiting the intermediate
members fails, we clear the error and unconditionally use
visit_end_struct() on the same error object; but if that
cleanup succeeds, we then skip the qapi_free call.

Until a later patch adds visit_check_struct(), the only safe
approach is to use two separate error objects.

ca47a926ad include/qemu/atomic: add compile time asserts
To be safely portable no atomic access should be trying to do more than
the natural word width of the host. The most common abuse is trying to
atomically access 64 bit values on a 32 bit host.

This patch adds some QEMU_BUILD_BUG_ON to the __atomic instrinsic paths
to create a build failure if (sizeof(*ptr) > sizeof(void *)).

compiler trying to come up with a suitable atomic operation on 32 bit
hosts. Because the variable is protected by vm_clock_seqlock, we check its
value inside a seqlock critical section.
