We'll need to check a part of qiov soon, so implement it now.

Optimization with align down to 4 * sizeof(long) is dropped due to:
1. It is strange: it aligns length of the buffer, but where is a
   guarantee that buffer pointer is aligned itself?
2. buffer_is_zero() is a better place for optimizations and it has
   them.

  target/alpha: fix tlb_fill trap_arg2 value for instruction fetch
Signed-off-by: NPeter Maydell <peter.maydell@linaro.org>

Commit e41c9452 ("target/alpha: Convert to CPUClass::tlb_fill")
slightly changed the way the trap_arg2 value is computed in case of TLB
fill. The type of the variable used in the ternary operator has been
changed from an int to an enum. This causes the -1 value to not be
sign-extended to 64-bit in case of an instruction fetch. The trap_arg2
ends up with 0xffffffff instead of 0xffffffffffffffff. Fix that by
changing the -1 into -1LL.

This fixes the execution of user space processes in qemu-system-alpha.

The tests/test-bdrv-drain /bdrv-drain/iothread/drain test case does the
following:

1. The preadv coroutine calls aio_bh_schedule_oneshot() and then yields.
2. The one-shot BH executes in another AioContext.  All it does is call
   aio_co_wakeup(preadv_co).
3. The preadv coroutine is re-entered and returns.

There is a race condition in aio_co_wake() where the preadv coroutine
returns and the test case destroys the preadv IOThread.  aio_co_wake()
can still be running in the other AioContext and it performs an access
to the freed IOThread AioContext.

Here is the race in aio_co_schedule():

  QSLIST_INSERT_HEAD_ATOMIC(&ctx->scheduled_coroutines,
                            co, co_scheduled_next);
  <-- race: co may execute before we invoke qemu_bh_schedule()!
  qemu_bh_schedule(ctx->co_schedule_bh);

So if co causes ctx to be freed then we're in trouble.  Fix this problem
by holding a reference to ctx.

Add a --engine option to select either docker, podman or auto.

Among other advantages, podman allows to run rootless & daemonless
containers, fortunately sharing compatible CLI with docker.

With current podman, we have to use a uidmap trick in order to be able
to rw-share the ccache directory with the container user.

With a user 1000, the default mapping is:                                                                                                                                                                         1000 (host) -> 0 (container).
So write access to /var/tmp/ccache ends will end with permission
denied error.

With "--uidmap 1000:0:1 --uidmap 0:1:1000", the mapping is:
1000 (host) -> 0 (container, 1st namespace) -> 1000 (container, 2nd namespace).
(the rest is mumbo jumbo to avoid holes in the range of UIDs)

A future podman version may have an option such as --userns-keep-uid.

Any access sets the reference bit. In case we have a read-fault, we
should not allow writes to the TLB entry if the change bit was not

This is a preparation for proper storage-key reference/change bit handling

bit (old KVM versions without the ioctl to carry out the translation).

Whenever we modify a storage key, we should flush the TLBs of all CPUs,
so the MMU fault handling code can properly consider the changed storage
key (to e.g., properly set the reference and change bit on the next
accesses).

These functions are barely used in modern Linux guests, so the performance
implications are neglectable for now.

This is a preparation for better reference and change bit handling for
TCG, which will require more MMU changes.

Instructions are always fetched from primary address space, except when
in home address mode. Perform the selection directly in cpu_mmu_index().

get_mem_index() is only used to perform data access, instructions are
fetched via cpu_lduw_code(), which translates to cpu_mmu_index(env, true).

We don't care about restricting the access permissions of the TLB
entries anymore, as we no longer enter PRIMARY entries into the

we now fetch 2 bytes first, check whether we have a 32 bit insn, and only then

this gets rid of the copied fields of TriCore's DisasContext and now
uses the shared DisasContextBase, which is necessary for the conversion
to translate_loop.
