big-endian this causes sysctlbyname() to fill in the upper bits of the

This will cause the "if transaction failed" code paths added in

during page table walks correctly (generating a translation

Convert the mmu_probe() function to using address_space_ldl()
rather than ldl_phys(), so we can explicitly detect memory
transaction failures.
This makes no practical difference at the moment, because
ldl_phys() will return 0 on a transaction failure, and we
treat transaction failures and 0 PDEs identically. However
the spec says that MMU probe operations are supposed to
update the fault status registers, and if we ever implement
that we'll want to distinguish the difference. For the
moment, just add a TODO comment about the bug.

With the unassigned_access hook in place, if these hit an unassigned
area of memory then the hook will cause us to wrongly generate
an exception with a fault address matching the address of the
page table entry.
Change to using address_space_ldl() so we can detect and correctly
handle bus errors and give them their correct behaviour of
causing a translation error with a suitable fault status register.
Note that this won't actually take effect until we switch the

Currently the SPARC target uses the old-style do_unassigned_access
hook. We want to switch it over to do_transaction_failed, but to do
this we must first remove all the direct calls in ldst_helper.c to
cpu_unassigned_access(). Factor out the body of the hook function's
code into a new sparc_raise_mmu_fault() and call it from the hook and
from the various places that used to call cpu_unassigned_access().
In passing, this fixes a bug where the code that raised the
MMU exception was directly calling GETPC() from a function that
was several levels deep in the callstack from the original
helper function: the new sparc_raise_mmu_fault() instead takes
the return address as an argument.
Other than the use of retaddr rather than GETPC() and a comment
format fixup, the body of the new function has no changes from
that of the old hook function.

This fixes subtle corruption introduced by luks threaded encryption
in commit 8ac0f15f33
Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1745922
The corruption happens when we do a write that
* writes to two or more unallocated clusters at once
* doesn't fully cover the first sector
* doesn't fully cover the last sector
* uses luks encryption
In this case, when allocating the new clusters we COW both areas
prior to the write and after the write, and we encrypt them.
The above mentioned commit accidentally made it so we encrypt the
second COW area using the physical cluster offset of the first area.
The problem is that offset_in_cluster in do_perform_cow_encrypt
can be larger that the cluster size, thus cluster_offset
will no longer point to the start of the cluster at which encrypted
area starts.
Next patch in this series will refactor the code to avoid all these
assumptions.
In the bugreport that was triggered by rebasing a luks image to new,
zero filled base, which lot of such writes, and causes some files
with zero areas to contain garbage there instead.
But as described above it can happen elsewhere as well

Background: As of cURL 7.59.0, it verifies that several functions are
not called from within a callback. Among these functions is
curl_multi_add_handle().
curl_read_cb() is a callback from cURL and not a coroutine. Waking up
acb->co will lead to entering it then and there, which means the current
request will settle and the caller (if it runs in the same coroutine)
may then issue the next request. In such a case, we will enter
curl_setup_preadv() effectively from within curl_read_cb().
Calling curl_multi_add_handle() will then fail and the new request will
not be processed.
Fix this by not letting curl_read_cb() wake up acb->co. Instead, leave
the whole business of settling the AIOCB objects to
curl_multi_check_completion() (which is called from our timer callback
and our FD handler, so not from any cURL callbacks).

QLIST_FOREACH_SAFE() list, which was actually wrong: SAFE foreaches are
only safe when the current element is removed in each iteration. If it
possible for the list to be concurrently modified, we cannot guarantee
that only the current element will be removed. Therefore, we must not
use QLIST_FOREACH_SAFE() here.

curl_multi_do(), too, just like it is done in curl_multi_read().

A follow-up patch will make curl_multi_do() and curl_multi_read() take a
CURLSocket instead of the CURLState. They still need the latter,
though, so add a pointer to it to the former.

qemu-io now prefixes its error and warnings with "qemu-io:".
36b9986b08 fixed a lot of iotests output but forget about
026.out.nocache. Fix it too.

The check script is already printing out which iotest is currently
running, so printing out the name of the check-block.sh shell script
looks superfluous here.

When running "make check -j8" or something similar, the iotests are
running in parallel with the other tests. So when they are printing
out "Passed all xx tests" or a similar status message at the end,
it might not be quite clear that this message belongs to the iotests,
since the output might be mixed with the other tests. Thus change the
word "tests" here to "iotests" instead to avoid confusion.

Replace confusing usage:
~BDRV_SECTOR_MASK
With more clear:
(BDRV_SECTOR_SIZE - 1)
Remove BDRV_SECTOR_MASK and the unused BDRV_BLOCK_OFFSET_MASK which was

Replace instances of:
(n & (BDRV_SECTOR_SIZE - 1)) == 0
And:
(n & ~BDRV_SECTOR_MASK) == 0
With:
QEMU_IS_ALIGNED(n, BDRV_SECTOR_SIZE)
Which reveals the intent of the code better, and makes it easier to
locate the code checking alignment.

devend_memop can rely on the fact that the result is always either
0 or MO_BSWAP, corresponding respectively to host endianness and
the opposite. Native (target) endianness in turn can be either
the host endianness, in which case MO_BSWAP is only returned for
host-opposite endianness, or the opposite, in which case 0 is only
returned for host endianness.
With this in mind, devend_memop can be compiled as a setcond+shift
for every target. Do this and, while at it, move it to
include/exec/memory.h since !NEED_CPU_H files do not (and should not)
need it.
