According to http://e2e.ti.com/support/arm/sitara_arm/f/791/t/210729 the
USB reset pulse has an undocumented duration of 200ns and during this
period the module must not be acessed.
We wait for 100us to take into account for some imprecision of the early
DELAY() loop.
This fixes the eventual 'External Non-Linefetch Abort (S)' that happens at
boot while resetting the musb subsystem.
While here, enable the USB subsystem clock before the first access.

Introduce a seperate phase to list all unavailable pools when listing
pools to upgrade. This avoids confusing output when displaying older
and disabled feature pools. These existing phases now silently skip
unavailable pools.
Introduce cb_unavail to upgrade_cbdata_t which enables the final
output for zpool list to correctly detail if all pools or only all
available pools where up-to-date on version / features.
Correct the type of upgrade_cbdata_t.cb_first from int -> boolean_t.
Change the pool iteration when upgrading named pools to include
unavailable pools and update upgrade_one so it doesn't try to upgrade
unavailable pools but warns about them. This allows the correct error
to be displayed as well as upgrades with available and unavailable
pools intermixed to partially complete.
Also correct some missing trailing \n's from output in upgrade_one.

The function savestr allows NULL return values during Plan A patching so in
case of out of memory conditions, Plan B can step in. In many cases, NULL
value is not properly handled, so use xstrdup here (it's outside Plan A/B
patching, which means that even Plan B relies on successful operations).

This enables the use of GPIO pins as interrupt sources for kernel devices
directly attached to gpiobus (userland notification will be added soon).
The use of gpio interrupts for other kernel devices will be possible when
intrng is complete.
All GPIO pins can be set to trigger on:
- active-low;
- active-high;
- rising edge;
- falling edge.
Tested on: Beaglebone-black
code, passing a 0/1 flag that indicates which type of abort it was. This
sets the stage for unifying the handling of page faults in a single routine.

If it seems like this is getting out of hand, I quite agree. I wonder if
it's safe, here in the 21st century, to lose the distinction between C and
ASM symbols?
around so that related things are more grouped together, rewrite comments.
No functional changes, this is all so that the functional changes in the
next commit will stand out.
'extra' entry points which are nested within or provide a synonym name
for another function. It's most likely not safe to be messing with the
IP and LR registers at anything other than the primary entry point to a
function. Anywhere beyond initial function entry, those registers may
be in use as scratch or variable registers.
semicolons between the code and comments instead of after the comments,

No functional changes.
Prior to this fix "zpool upgrade" and "zpool upgrade -a" would fail due to
an assert when operating on unavailable pools.
We now print a warning to stderr but allow the processing of other pools
to procesed.

was reported via email. This was caused by a LOR between the
sleep lock used to serialize the local locking (nfsrv_locklf())
and locking the vnode. I believe this patch fixes the problem
by delaying relocking of the vnode until the sleep lock is
unlocked (nfsrv_unlocklf()). To avoid nfsvno_advlock() having the side
effect of unlocking the vnode, unlocking the vnode was moved to before
the functions that call nfsvno_advlock().
It shouldn't affect the execution of the default case where
vfs.nfsd.enable_locallocks=0.

locks/unlocks the vnode and does a VOP_GETATTR()
for the SEEK_END case. This is safe to do, since
lf_advlock{async}() only uses the size argument
for the SEEK_END case.
The NFSv4 server needs this when
vfs.nfsd.enable_locallocks!=0 since locking the
vnode results in a LOR that can cause a deadlock
for the nfsd threads.

- Eliminate unused irqframe
- Eliminate unused saframe
- Instead of splitting r4-sp storage between the stack and switchframe,
just put all the registers in switchframe and eliminate the un_32 struct.

The ARM image builds build the in-tree gcc in order to build u-boot
and gperf is needed to build gcc, but is no longer installed on archs
that use clang.
Invoking the make targets as separate steps is done to work around
a build failure which is not yet fully understood.

IPv6. Initialize it only once in def_policy_init(). Remove its
initialization from key_init() and make it static.
Remove several fields from struct secpolicy:
* lock - it isn't so useful having mutex in the structure, but the only
thing we do with it is initialization and destroying.
* state - it has only two values - DEAD and ALIVE. Instead of take a lock
and change the state to DEAD, then take lock again in GC function and
delete policy from the chain - keep in the chain only ALIVE policies.
* scangen - it was used in GC function to protect from sending several
SADB_SPDEXPIRE messages for one SPD entry. Now we don't keep DEAD entries
in the chain and there is no need to have scangen variable.
Use TAILQ to implement SPD entries chain. Use rmlock to protect access
to SPD entries chain. Protect all SP lookup with RLOCK, and use WLOCK
when we are inserting (or removing) SP entry in the chain.
Instead of using pattern "LOCK(); refcnt++; UNLOCK();", use refcount(9)
API to implement refcounting in SPD. Merge code from key_delsp() and
_key_delsp() into _key_freesp(). And use KEY_FREESP() macro in all cases
when we want to release reference or just delete SP entry.
