The STE_CTXPTR() and STE_S2TTB() macros both extract two halves
of an address from fields in the STE and combine them into a
single value to return. The current code for this uses a GCC
statement expression. There are two problems with this:
(1) The type chosen for the variable in the statement expr
is 'unsigned long', which might not be 64 bits
(2) the name chosen for the variable causes -Wshadow warnings
because it's the same as a variable in use at the callsite:
In file included from ../../hw/arm/smmuv3.c:34:
../../hw/arm/smmuv3.c: In function ‘smmu_get_cd’:
../../hw/arm/smmuv3-internal.h:538:23: warning: declaration of ‘addr’ shadows a previous local [-Wshadow=compatible-local]
538 | unsigned long addr; \
| ^~~~
../../hw/arm/smmuv3.c:339:23: note: in expansion of macro ‘STE_CTXPTR’

| ^~~~~~~~~~
../../hw/arm/smmuv3.c:339:16: note: shadowed declaration is here
339 | dma_addr_t addr = STE_CTXPTR(ste);
| ^~~~
Sidestep both of these problems by just using a single
expression rather than a statement expr.
For CMD_ADDR, we got the type of the variable right but still
run into -Wshadow problems:
In file included from ../../hw/arm/smmuv3.c:34:
../../hw/arm/smmuv3.c: In function ‘smmuv3_range_inval’:
../../hw/arm/smmuv3-internal.h:334:22: warning: declaration of ‘addr’ shadows a previous local [-Wshadow=compatible-local]

| ^~~~~~~~
../../hw/arm/smmuv3.c:1104:21: note: shadowed declaration is here
1104 | dma_addr_t end, addr = CMD_ADDR(cmd);
| ^~~~
so convert it too.
CD_TTB has neither problem, but it is the only other macro in
the file that uses this pattern, so we convert it also for
consistency's sake.
We use extract64() rather than extract32() to avoid having
to explicitly cast the result to uint64_t.

We are doing things like
nb_sectors /= (s->qdev.blocksize / BDRV_SECTOR_SIZE);
in the code here (e.g. in scsi_disk_emulate_mode_sense()), so if
the blocksize is smaller than BDRV_SECTOR_SIZE (=512), this crashes
with a division by 0 exception. Thus disallow block sizes of 256
bytes to avoid this situation.

The for-loop does not make much sense here - it is always left after
the first iteration, so we can also check for nb_nics == 1 instead
which is way easier to understand.
Also, the checks for nd->model are superfluous since the code in
mips_jazz_init_net() calls qemu_check_nic_model() that already
takes care of this (i.e. initializing nd->model if it has not been
set yet, and checking whether it is the "help" option or the
supported NIC model).

The mips_jazz_init() function is already quite big, so moving
away some code here can help to make it more understandable.
Additionally, by moving this code into a separate function, the
next patch (that will refactor the for-loop around the NIC init
code) will be much shorter and easier to understand.

- The comment is incorrectly indented / formatted.
- The comment states a 8MB limit, even though the code enforces a 16MB
limit.
Both of these warts come from commit 0657c657eb ("hw/i386/pc: add max
combined fw size as machine configuration option", 2020-12-09); clean them
up.
Arguably, it's also better to be consistent with the binary units (such as
"MiB") that QEMU uses nowadays.

Block-TLB support and linux-user fixes for hppa target
All 32-bit hppa CPUs allow a fixed number of TLB entries to have a
different page size than the default 4k.
Those are called "Block-TLBs" and are created at startup by the
operating system and managed by the firmware of hppa machines
through the firmware PDC_BLOCK_TLB call.
This patchset adds the necessary glue to SeaBIOS-hppa and
qemu to allow up to 16 BTLB entries in the emulation.
Two patches from Mikulas Patocka fix signal delivery issues
in linux-user on hppa.

The synchronous bdrv_aio_cancel() function needs the acb's AioContext so
it can call aio_poll() to wait for cancellation.
It turns out that all users run under the BQL in the main AioContext, so
this callback is not needed.
Remove the callback, mark bdrv_aio_cancel() GLOBAL_STATE_CODE just like
its blk_aio_cancel() caller, and poll the main loop AioContext.
The purpose of this cleanup is to identify bdrv_aio_cancel() as an API
that does not work with the multi-queue block layer.
