The actual imx_eth_enable_rx() function is buggy.
It updates s->regs[ENET_RDAR] after calling qemu_flush_queued_packets().
qemu_flush_queued_packets() is going to call imx_XXX_receive() which itself
is going to call imx_eth_enable_rx().
By updating s->regs[ENET_RDAR] after calling qemu_flush_queued_packets()
we end up updating the register with an outdated value which might
lead to disabling the receive function in the i.MX FEC/ENET device.
This patch change the place where the register update is done so that the
register value stays up to date and the receive function can keep
running.

Commit ("3b39d734141a target/arm: Handle page table walk load failures
correctly") modified both versions of the page table walking code (i.e.,
arm_ldl_ptw and arm_ldq_ptw) to record the result of the translation in
a temporary 'data' variable so that it can be inspected before being
returned. However, arm_ldq_ptw() returns an uint64_t, and using a
temporary uint32_t variable truncates the upper bits, corrupting the
result. This causes problems when using more than 4 GB of memory in
a TCG guest. So use a uint64_t instead.

If multiple guest threads in user-mode emulation write to a
page which QEMU has marked read-only because of cached TCG
translations, the threads can race in page_unprotect:
* threads A & B both try to do a write to a page with code in it at
the same time (ie which we've made non-writeable, so SEGV)
* they race into the signal handler with this faulting address
* thread A happens to get to page_unprotect() first and takes the
mmap lock, so thread B sits waiting for it to be done
* A then finds the page, marks it PAGE_WRITE and mprotect()s it writable
* A can then continue OK (returns from signal handler to retry the
memory access)
* ...but when B gets the mmap lock it finds that the page is already
PAGE_WRITE, and so it exits page_unprotect() via the "not due to
protected translation" code path, and wrongly delivers the signal
to the guest rather than just retrying the access
In particular, this meant that trying to run 'javac' in user-mode
emulation would fail with a spurious guest SIGSEGV.
Handle this by making page_unprotect() assume that a call for a page
which is already PAGE_WRITE is due to a race of this sort and return
a "fault handled" indication.
Since this would cause an infinite loop if we ever called
page_unprotect() for some other kind of fault than "write failed due
to bad access permissions", tighten the condition in
handle_cpu_signal() to check the signal number and si_code, and add a
comment so that if somebody does ever find themselves debugging an
infinite loop of faults they have some clue about why.
(The trick for identifying the correct setting for
current_tb_invalidated for thread B (needed to handle the precise-SMC
case) is due to Richard Henderson. Paolo Bonzini suggested just
relying on si_code rather than trying anything more complicated.)

some other kind of fault, so change the functions to pass through

mmap() is required by the linux kernel ABI and POSIX to return a
non-NULL address when the implementation chooses a start address for the
mapping.
The current implementation of mmap_find_vma_reserved() can return NULL
as start address of a mapping which leads to subsequent crashes inside
the guests glibc, e.g. output of qemu-arm-static --strace executing a
test binary stx_test:
1879 mmap2(NULL,8388608,PROT_READ|PROT_WRITE,MAP_PRIVATE|MAP_ANONYMOUS|0x20000,-1,0) = 0x00000000
1879 write(2,0xf6fd39d0,79) stx_test: allocatestack.c:514: allocate_stack: Assertion `mem != NULL' failed.
This patch fixes mmap_find_vma_reserved() by skipping NULL as start
address while searching for a suitable mapping start address.

The handling of length calculations in host_to_target_cmsg()
was rather confused:
* when checking for whether the target cmsg header fit in
the remaining buffer, we were using the host struct size,
not the target size
* we were setting tgt_len to "target payload + header length"
but then using it as if it were the target payload length alone
* in various message type cases we weren't handling the possibility
that host or target buffers were truncated
Fix these problems. The second one in particular is liable
to result in us overrunning the guest provided buffer,
since we will try to convert more data than is actually
present.

When we do a fork() in usermode emulation, we need to be in
a start/end exclusive section, so that we can ensure that no
other thread is in an RCU section. Otherwise you can get this
deadlock:
- fork thread: has mmap_lock, waits for rcu_sync_lock
(because rcu_init_lock() is registered as a pthread_atfork() hook)
- RCU thread: has rcu_sync_lock, waits for rcu_read_(un)lock
- another CPU thread: in RCU critical section, waits for mmap_lock
This can show up if you have a heavily multithreaded guest program
that does a fork().

Our locking order is that the tb lock should be taken
inside the mmap_lock, but fork_start() grabs locks the
other way around. This means that if a heavily multithreaded
guest process (such as Java) calls fork() it can deadlock,
with the thread that called fork() stuck in fork_start()
with the tb lock and waiting for the mmap lock, but some
other thread in tb_find() with the mmap lock and waiting
for the tb lock. The cpu_list_lock() should also always be
taken last, not first.
Fix this by making fork_start() grab the locks in the
right order. The order in which we drop locks doesn't
matter, so we leave fork_end() the way it is.

There is a bit of image-specific information which depends on the qcow2
compat level. Filter it so that 198 works with compat=0.10 (and any
refcount_bits value).
Note that we cannot simply drop the --format-specific switch because we
do need the "encrypt" information.

In order for 191 to work with an explicit refcount_bits or compat=0.10,
we should strip format-specific information from the output--and we can
do so by using _filter_img_info.

067 works very well with compat=0.10 once you remove format-specific

051 has both compat=1.1 and compat=0.10 tests (once it uses
lazy_refcounts, once it tests that setting them does not work).
For the compat=0.10 tests, it already explicitly creates a suitable
image. So let's just ignore the user-specified compat level for the
lazy_refcounts test and explicitly create a compat=1.1 image there, too.

This test does funny things like TEST_IMG="TEST_IMG.base" _make_test_img
that usually only work with the file protocol. More specifically, they
do not work with the most interesting non-file protocols, so we might as
well skip this for anything but file.

_filter_img_info should remove format-specific information, too. We
already have such a filter in _img_info, and it is very useful for
query-block-named-block-nodes (etc.), too.
However, in 198 we need that information (but we still want the rest of
the filter), so make that filtering optional. Note that "the rest of
the filter" includes filtering of the test directory, so we can drop the
_filter_testdir from 198 at the same time.

Persistent dirty bitmaps require a properly functioning
autoclear_features field, or we cannot track when an unsupporting
program might overwrite them. Therefore, we cannot support them for
