Function phys_page_set() and phys_page_set_level() 's argument *nb*
stands for number of pages to set instead of hardware address.
This would be more proper to use uint64_t instead of hwaddr for its
type.
Backports commit 56b15076805a29673c1a90ea9c3ebef25bfcc912 from qemu
Switch the MIPS target from the old unassigned_access hook to the new
do_transaction_failed hook.
Unlike the old hook, do_transaction_failed is only ever called from
the TCG memory access paths, so there is no need for the "ignore this
if we're using KVM" hack that we were previously using to work around
the way unassigned_access was called for all kinds of memory accesses
to unassigned physical addresses.
The MIPS target does not ever do direct memory reads by physical
address (via either ldl_phys etc or address_space_ldl etc), so the
only memory accesses this affects are the 'normal' guest loads and
stores, which will be handled by the new hook; their behaviour is
unchanged.
Backports commit 4f02a06d50ef0081089ed8cb3ec7c7986e3c95f8 from qemu
Document the use of g_autofree and g_autoptr in glib for automatic
freeing of memory.

The split of information between the two docs is rather arbitary and
unclear. It is simpler for contributors if all the information is in
one file.
Backports commit 637f39568fc0bd9848fd9d225d52ab0c4c443ed3 from qemu
There are only two remaining uses of gen_bx_im. In each case, we
know the destination mode -- not changing in the case of gen_jmp
or changing in the case of trans_BLX_i. Use this to simplify the
surrounding code.
For trans_BLX_i, use gen_jmp for the actual branch. For gen_jmp,
use gen_set_pc_im to set up the single-step.

Now that all callers pass a constant value, split the switch
statement into the individual trans_* functions.
Backports commit 279de61a21a1622cb875ead82d6e78c989ba2966 from qemu
Add a check for ARMv6 in trans_CPS. We had this correct in
the T16 path, but had previously forgotten the check on the
A32 and T32 paths.

Fold away all of the cases that now just goto illegal_op,
because all of their internal bits are now in decodetree.

Backports commit f843e77144c9334e244a422848177f2fbef5eb05 from qemu
We have been using store_reg and not store_reg_for_load when writing
back a loaded value into the base register. At first glance this is
incorrect when base == pc, however that case is UNPREDICTABLE.

This has been a TODO item for quite a while. The minimum bit
count for A32 and T16 is 1, and for T32 is 2.

Prior to v7, for the A32 encoding, this operation wrote an UNKNOWN
value back to the base register. Starting in v7 this is UNPREDICTABLE.
Backports commit 3949f4675d13c587078f8f423845a3a537a22595 from qemu
This includes a minor bug fix to LDM (user), which requires
bit 21 to be 0, which means no writeback.
