The previous implementation incorrectly used same macro to detect overflow for addition and subtraction. This patch makes distinction between these two, and creates separate macros. The affected routines are changed accordingly. This change also includes additions to the existing tests for SUBQ_S_PH and SUBQ_S_W that would trigger the fixed issue, and it removes dead code from the test file. The last test case in subq_s_w.c is a bug found/reported/ isolated by Klaus Peichl from Dolby.

During a commit of 'all' using the HMP non-live commit, the operation is aborted and returns error on the first error enountered. When non-COW drives are in use (e.g. ejected floppy, cdrom, or drives without a backing parent), that means a commit all will return an error of either -ENOMEDIUM or -ENOTSUP. This is not desirable, so for the 'all' commit case, only attempt the commit if both bs->drv and bs->backing_hd are present. More succinctly: 'commit all' now means a commit on all COW drives. This means an individual commit to a specific non-COW drive will still return the appropriate error (-ENOMEDIUM if eject / not present, -ENOTSUP if no backing file).

During the review of the dataplane code, the EventPoll API morphed itself (not concidentially) into something very very similar to an AioContext. Thus, it is trivial to convert virtio-blk-dataplane to use AioContext, and a first baby step towards letting dataplane talk directly to the QEMU block layer. The only interesting note is the value-copy of EventNotifiers. At least in my opinion this is part of the EventNotifier API and is even portable to Windows. Of course, in this case you should not close the notifier's underlying file descriptors or handle with event_notifier_cleanup.

Fix some of the nasty TCG race conditions and crashes by implementing cpu_exit() as setting a flag which is checked at the start of each TB. This avoids crashes if a thread or signal handler calls cpu_exit() while the execution thread is itself modifying the TB graph (which may happen in system emulation mode as well as in linux-user mode with a multithreaded guest binary). This fixes the crashes seen in LP:668799; however there are another class of crashes described in LP:1098729 which stem from the fact that in linux-user with a multithreaded guest all threads will use and modify the same global TCG date structures (including the generated code buffer) without any kind of locking. This means that multithreaded guest binaries are still in the "unsupported" category.

If tcg_qemu_tb_exec() returns a value whose low bits don't indicate a link to an indexed next TB, this means that the TB execution never started (eg because the instruction counter hit zero). In this case the guest PC has to be reset to the address of the start of the TB. Refactor the cpu-exec code to make all tcg_qemu_tb_exec() calls pass through a wrapper function which does this restoration if necessary. Note that the apparent change in cpu_exec_nocache() from calling cpu_pc_from_tb() with the old TB to calling it with the TB returned by do_tcg_qemu_tb_exec() is safe, because in the nocache case we can guarantee that the TB we try to execute is not linked to any others, so the only possible returned TB is the one we started at. That is, we should arguably previously have included in cpu_exec_nocache() an assert(next_tb & ~TB_EXIT_MASK) == tb), since the API requires restore from next_tb but we were using tb.

Currently, M25P80 uses an object property to differentiate between flash parts. Changed this over to use QOM sub-classes - the actual names of the different parts are used to create a set of dynamic classes which passes the part info as class data. The object no longer needs to search the known_devices table for itself, instead it just gets its info from its own class. Kept the intermediate class definition private to m25p80.c for the moment, as the expectation is parts will only be added as new entries in the table. We can factor out the TYPE_M25P80 abstraction into a header on a demand basis.

In QEMU emulation, there is no functional difference between the ARM mpcore private timers and watchdogs. Removed all the distinction between the two from arm_mptimer.c and converted it to be just the mptimer. a9mpcore and arm11mpcore just instantiate the same mptimer object twice to get both timer and WDT. If in the future we want to make the WDT functionally different then we can use either QOM hierarchy to derive WDT from from mptimer, or we can add a property "is-wdt" or some such.

The code for handling the default "unknown command state" case in pflash_read in pflash_cfi01.c comments "reset state & treat it as a read". However the code doesn't actually do this. Moving the default case to the top of the switch so it can fall through into the read case brings this file into line with pflash_cfi02 and makes the code behave as the comments suggest. The pflash_cfi01 code has always had this bug -- it was presumably introduced when the original author copied the cfi02 code and rearranged the order of the switch statement without noticing that the default case relied on the fall-through.
