If DMA's owning thread cancels the IO while the bounce buffer's owning thread
is notifying the "cpu client list", a use-after-free happens:
continue_after_map_failure dma_aio_cancel
------------------------------------------------------------------
aio_bh_new
qemu_bh_delete
qemu_bh_schedule (use after free)
Also, the old code doesn't run the bh in the right AioContext.
Fix both problems by passing a QEMUBH to cpu_register_map_client.

Rather than retaining io_mem_read/write as simple wrappers around
the memory_region_dispatch_read/write functions, make the latter
public and change all the callers to use them, since we need to
touch all the callsites anyway to add MemTxAttrs and MemTxResult
support. Delete io_mem_read and io_mem_write entirely.
(All the callers currently pass MEMTXATTRS_UNSPECIFIED
and convert the return value back to bool or ignore it.)

Define an API so that devices can register MemoryRegionOps whose read
and write callback functions are passed an arbitrary pointer to some
transaction attributes and can return a success-or-failure status code.
This will allow us to model devices which:
* behave differently for ARM Secure/NonSecure memory accesses
* behave differently for privileged/unprivileged accesses
* may return a transaction failure (causing a guest exception)
for erroneous accesses
This patch defines the new API and plumbs the attributes parameter through
to the memory.c public level functions io_mem_read() and io_mem_write(),
where it is currently dummied out.
The success/failure response indication is also propagated out to
io_mem_read() and io_mem_write(), which retain the old-style
boolean true-for-error return.

This is improved type checking for the translators -- it's no longer
possible to accidentally swap arguments to the branch functions.
Note that the code generating backends still manipulate labels as int.
With notable exceptions, the scope of the change is just a few lines
for each target, so it's not worth building extra machinery to do this
change in per-target increments.

which is not correct.

Allow "unlocked" reads of the ram_list by using an RCU-enabled QLIST.
The ramlist mutex is kept. call_rcu callbacks are run with the iothread
lock taken, but that may change in the future. Writers still take the
ramlist mutex, but they no longer need to assume that the iothread lock
is taken.
Readers of the list, instead, no longer require either the iothread
or ramlist mutex, but they need to use rcu_read_lock() and
rcu_read_unlock().
One place in arch_init.c was downgrading from write side to read side
like this:
qemu_mutex_lock_iothread()
qemu_mutex_lock_ramlist()
...
qemu_mutex_unlock_iothread()
...
qemu_mutex_unlock_ramlist()
and the equivalent idiom is:
qemu_mutex_lock_ramlist()
rcu_read_lock()
...
qemu_mutex_unlock_ramlist()
...
rcu_read_unlock()

address_space_destroy_dispatch is called from an RCU callback and hence
outside the iothread mutex (BQL). However, after address_space_destroy
no new accesses can hit the destroyed AddressSpace so it is not necessary
to observe changes to the memory map. Move the memory_listener_unregister
call earlier, to make it thread-safe again.

Use inline functions rather than macros for cpu_ld/st accessors
for the *-user configurations, as we already do for softmmu.
This has a two advantages:
* we can actually typecheck our arguments
* we don't need to leak the _raw macros everywhere
Since the _kernel functions were only used by target-i386/seg_helper.c,
put the definitions for them in that file too. (It already has the
similar template include code to define them for the softmmu case,
so it makes sense to have it deal with defining them for user-only.)

This used_length size can change across reboots.
Follow up patches will change used_length for such blocks at migration,
making it easier to extend devices using such RAM (notably ACPI,
but in the future thinkably other ROMs) without breaking migration
compatibility or wasting ROM (guest) memory.
Device is notified on resize, so it can adjust if necessary.
Note: nothing prevents making all RAM resizeable in this way.
However, reviewers felt that only enabling this selectively will
