Commit 1901b4967c changed the nvme device from using a bar exclusive
for MSI-x to sharing it on bar0.
Unfortunately, the msix_uninit_exclusive_bar() call remains in
nvme_exit() which causes havoc when the device is removed with, say,
device_del. Fix this.
Additionally, a subregion is added but it is not removed on exit which
causes a reference to linger and the drive to never be unlocked.

When adding this file and its new content in commit 3f7a927847
("target/mips: LSA/DLSA R6 decodetree helpers") I did 2 mistakes:
1: Listed authors who haven't been involved in its development,
2: Used an incorrect GNU GPLv2 license text (using 'and' instead
of 'or').
Instead of correcting the GNU GPLv2 license text, replace the license
by the 'GNU LGPL v2.1 or later' one, to be coherent with the other
translation files in the target/mips/ folder.

Result @blocked is true when and only when result @blocked-reasons is
present. It's always non-empty when present. @blocked is redundant.
It was introduced in commit 3af8554bd0 "migration: Add blocker
information", and has not been released. This gives us a chance to
fix the interface with minimal fuss.
Unfortunately, we're already too close to the release to risk dropping
it. Deprecate it instead.

While processing SCSI i/o requests in mptsas_process_scsi_io_request(),
the Megaraid emulator appends new MPTSASRequest object 'req' to
the 's->pending' queue. In case of an error, this same object gets
dequeued in mptsas_free_request() only if SCSIRequest object
'req->sreq' is initialised. This may lead to a use-after-free issue.
Since s->pending is actually not used, simply remove it from
MPTSASState.

By definition a single instruction is capable of being an IO
instruction. This avoids a problem of triggering a cpu_io_recompile on
a non-recorded translation which then fails because it expects
tcg_tb_lookup() to succeed unconditionally. The normal use case
requires a TB to be able to resolve machine state.
The other users of tcg_tb_lookup() are able to tolerate a missing TB
if the machine state has been resolved by other means - which in the
single-shot case is always true because machine state is synced at the
start of a block.

This is a left over erroneous check from the days front-ends handled
io start/end themselves. Regardless just because IO could be performed
on the last instruction doesn't obligate the front end to do so.
This fixes an abort faced by the aspeed execute-in-place support which
will necessarily trigger this state (even before the one-shot
CF_LAST_IO fix). The test still seems to hang once it attempts to boot
the Linux kernel but I suspect this is an unrelated issue with icount
and the timer handling code.
The original intention of the cpu_abort (added in commit 2e70f6efa8
when the icount stuff was first added) seems to have been to act as
an assert() to catch an unhandled corner case where the generated code
would be something like:
conditional branch to condlabel if its cc failed
implementation of the insn (a conditional branch or trap)
code emitted by gen_io_end()
condlabel:
gen_goto_tb or equivalent thing to go to next insn
At runtime the cc-failed case would skip over the code emitted by
gen_io_end(), leaving the can_do_io flag incorrectly set.
In commit ba3e792669 we switched to an implementation which
always clears can_do_io at the start of the following TB instead
of trying to clear it at the end of a TB that did IO. So the corner
case that this cpu_abort() was trying to flag is no longer possible,
because the gen_io_end() call has been deleted. We can therefore
safely remove the no-longer-valid assertion.
