After discussing on the mailing list it turns out that
accessing the flash memory from the kernel can disrupt CPU
sleep states and CPU hotplugging, so let's disable this
DT node by default. Setups that want to access the flash
can modify this entry to enable the flash again.
Quoting Sudeep Holla: "the firmware assumes the flash is
always in read mode while Linux leaves NOR flash in
"read id" mode after initialization."

Commit 073db4a51ee4 ("mtd: fix: avoid race condition when accessing
mtd->usecount") fixed a race condition but due to poor ordering of the
mutex acquisition, introduced a potential deadlock.
The deadlock can occur, for example, when rmmod'ing the m25p80 module, which
will delete one or more MTDs, along with any corresponding mtdblock
devices. This could potentially race with an acquisition of the block
device as follows.
-> blktrans_open()
-> mutex_lock(&dev->lock);
-> mutex_lock(&mtd_table_mutex);
-> del_mtd_device()
-> mutex_lock(&mtd_table_mutex);
-> blktrans_notify_remove() -> del_mtd_blktrans_dev()
-> mutex_lock(&dev->lock);
This is a classic (potential) ABBA deadlock, which can be fixed by
making the A->B ordering consistent everywhere. There was no real
purpose to the ordering in the original patch, AFAIR, so this shouldn't
be a problem. This ordering was actually already present in
del_mtd_blktrans_dev(), for one, where the function tried to ensure that
its caller already held mtd_table_mutex before it acquired &dev->lock:
if (mutex_trylock(&mtd_table_mutex)) {
mutex_unlock(&mtd_table_mutex);
BUG();
}
So, reverse the ordering of acquisition of &dev->lock and &mtd_table_mutex so
we always acquire mtd_table_mutex first.

This reverts commit 7eb418851f3278de67126ea0c427641ab4792c57.
This commit is poorly justified, I can find not discusison in email,
and it clearly causes a problem.
If a device which is being recovered fails and is subsequently
re-added to an array, there could easily have been changes to the
array *before* the point where the recovery was up to. So the
recovery must start again from the beginning.
If a spare is being recovered and fails, then when it is re-added we
really should do a bitmap-based recovery up to the recovery-offset,
and then a full recovery from there. Before this reversion, we only
did the "full recovery from there" which is not corect. After this
reversion with will do a full recovery from the start, which is safer
but not ideal.
It will be left to a future patch to arrange the two different styles
of recovery.

After commit 566c09c53455 ("raid5: relieve lock contention in get_active_stripe()")
__find_stripe() is called under conf->hash_locks + hash.
But handle_stripe_clean_event() calls remove_hash() under
conf->device_lock.
Under some cirscumstances the hash chain can be circuited,
and we get an infinite loop with disabled interrupts and locked hash
lock in __find_stripe(). This leads to hard lockup on multiple CPUs
and following system crash.
I was able to reproduce this behavior on raid6 over 6 ssd disks.
The devices_handle_discard_safely option should be set to enable trim

provider (the clock provider with new compatible). However support for
these devices was not added to existing drivers (rtc-s5m, clk-s2mps11).
New drivers were not submitted neither.
This means that the name of children devices is completely unused. The

Just like other NAND controllers, the NAND READID command only works
in 8bit mode for all versions of BRCMNAND controller.
This patch forces 8bit mode for each NAND CS in brcmnand_init_cs()
before doing nand_scan_ident() to ensure that BRCMNAND controller
is in 8bit mode when NAND READID command is issued.
