When unloading the driver that drives an EISA board, a message similar to the
following one is displayed:

Trying to free nonexistent resource <0000000000013000-000000000001301f>

Then an user is unable to reload the driver because the resource it requested in
the previous load hasn't been freed. This happens most probably due to a typo in
vortex_eisa_remove() which calls release_region() with 'dev->base_addr'  instead
of 'edev->base_addr'...

This patch fixes race between inet_frag_lru_move() and inet_frag_lru_add()
which was introduced in commit 3ef0eb0d
("net: frag, move LRU list maintenance outside of rwlock")

One cpu already added new fragment queue into hash but not into LRU.
Other cpu found it in hash and tries to move it to the end of LRU.
This leads to NULL pointer dereference inside of list_move_tail().

Another possible race condition is between inet_frag_lru_move() and
inet_frag_lru_del(): move can happens after deletion.

This patch initializes LRU list head before adding fragment into hash and
inet_frag_lru_move() doesn't touches it if it's empty.

I saw this kernel oops two times in a couple of days.

Some ancient pHyp versions used to create a 8 bytes local-mac-address
property in the device-tree instead of a 6 bytes one for veth.

The Linux driver code to deal with that is an insane hack which also
happens to break with some choices of MAC addresses in qemu by testing
for a bit in the address rather than just looking at the size of the
property.

Sanitize this by doing the latter instead.

Merge ipc fixes and cleanups from my IPC branch.

The ipc locking has always been pretty ugly, and the scalability fixes
to some degree made it even less readable.  We had two cases of double
unlocks in error paths due to this (one rcu read unlock, one semaphore
unlock), and this fixes the bugs I found while trying to clean things up
a bit so that we are less likely to have more.

* ipc-cleanups:
  ipc: simplify rcu_read_lock() in semctl_nolock()
  ipc: simplify semtimedop/semctl_main() common error path handling
  ipc: move sem_obtain_lock() rcu locking into the only caller
  ipc: fix double sem unlock in semctl error path
  ipc: move the rcu_read_lock() from sem_lock_and_putref() into callers
  ipc: sem_putref() does not need the semaphore lock any more
  ipc: move rcu_read_unlock() out of sem_unlock() and into callers

With various straight RCU lock/unlock movements, one common exit path
pattern had become

	rcu_read_unlock();
	goto out_wakeup;

and in fact there were no cases where we wanted to exit to out_wakeup
_without_ releasing the RCU read lock.

So replace that pattern with "goto out_rcu_wakeup", and remove the old
out_wakeup.

sem_obtain_lock() was another of those functions that returned with the
RCU lock held for reading in the success case.  Move the RCU locking to
the caller (semtimedop()), making it more obvious.  We already did RCU
locking elsewhere in that function.

Side note: why does semtimedop() re-do the semphore lookup after the
sleep, rather than just getting a reference to the semaphore it already
looked up originally?

This is another ipc semaphore locking cleanup, trying to make the
locking more straightforward.  We move the rcu read locking into the
callers of sem_lock_and_putref(), which in general means that we now
mostly do the rcu_read_lock() and rcu_read_unlock() in the same
function.

Mostly.  We still have the ipc_addid/newary/freeary mess, and things
like ipcctl_pre_down_nolock().

   - Fix a bit width test failure that resulted in old eMMC cards being

   - Expose fwrev/hwrev for MMCv4 parts.
   - Improve card removal logic in the case where the card's removed
