[ Upstream commit d8bf77a1dc ]
With the PG_arch_1 we keep track if the page's data cache is clean,
architecture rely on this property to treat new pages as dirty with
respect to the data cache and perform the flushing before mapping the pages
into userspace.
This patch adds a new architecture hook, arch_clear_hugepage_flags,so that
architectures which rely on the page flags being in a particular state for
fresh allocations can adjust the flags accordingly when a page is freed
into the pool.

However, next_victim_seg[gc_type] still has the last segment number

[ Upstream commit 57d67c6e82 ]
Instead of doing manual queue management, let's use the crypto/engine
for that.
In the same time, rework the requests handling to be easier to
understand (and fix all bugs related to them).

[ Upstream commit d6b23ccef8 ]
The key should not be set in hardware too much in advance, this will
fail it 2 TFM with different keys generate alternative requests.
The key should be stored and used just before doing cipher operations.

[ Upstream commit 68ef8af09a ]
The hardware does not handle 0 size length request, let's add a
fallback.
Furthermore fallback will be used for all unaligned case the hardware
cannot handle.

[ Upstream commit 87e356c496 ]
Storing the mode globally does not work if 2 requests are handled in the
same time.
We should store it in a request context.

[ Upstream commit c50ef1411c ]
The clock enable/disable at tfm init/exit is fragile,
if 2 tfm are init in the same time and one is removed just after,
it will leave the hardware uncloked even if a user remains.
Instead simply enable clocks at probe time.
We will do PM later.

[ Upstream commit 28fc4e9077 ]
Because the set/clear SBI_IS_RESIZEFS flag not between any locks,
In the following case:
thread1 thread2
->ioctl(resizefs)
->set RESIZEFS flag ->ioctl(resizefs)
... ->set RESIZEFS flag
->clear RESIZEFS flag
->resizefs stream
# No RESIZEFS flag in the stream
Also before freeze_super, the resizefs not started, we should not set
the SBI_IS_RESIZEFS flag.
So move the set/clear SBI_IS_RESIZEFS flag between the cp_mutex and
gc_lock.

According to the implementations of cred_label() and set_cred_label(),
we should use pointer to struct aa_label for lbs_cred instead of struct
aa_task_ctx, this patch fixes it.
