Both the fence and event alloc are safe to be done without holding the GPU
lock, as they either don't need any locking (fences) or are protected by
their own lock (events).
This solves a bad locking interaction between the submit path and the
recover worker. If userspace manages to exhaust all available events while
the GPU is hung, the submit will wait for events to become available
holding the GPU lock. The recover worker waits for this lock to become
available before trying to recover the GPU which frees up the allocated
events. Essentially both paths are deadlocked until the submit path
times out waiting for available events, failing the submit that could
otherwise be handled just fine if the recover worker had the chance to
bring the GPU back in a working state.

Sander reports following splat after netfilter nat bysrc table got

[<ffffffff8146da1d>] rhashtable_insert_rehash+0x5d/0xe0
[<ffffffff819fcfff>] nf_nat_setup_info+0x2ef/0x400
The failure happens when allocating the spinlock array.
Even with GFP_KERNEL its unlikely for such a large allocation
to succeed.
Thomas Graf pointed me at inet_ehash_locks_alloc(), so in addition
to adding NOWARN for atomic allocations this also makes the bucket-array
sizing more conservative.
In commit 095dc8e0c3686 ("tcp: fix/cleanup inet_ehash_locks_alloc()"),
Eric Dumazet says: "Budget 2 cache lines per cpu worth of 'spinlocks'".
IOW, consider size needed by a single spinlock when determining
number of locks per cpu. So with 64 byte per cacheline and 4 byte per
spinlock this gives 32 locks per cpu.
Resulting size of the lock-array (sizeof(spinlock) == 4):
cpus: 1 2 4 8 16 32 64
old: 1k 1k 4k 8k 16k 16k 16k
new: 128 256 512 1k 2k 4k 8k
8k allocation should have decent chance of success even
with GFP_ATOMIC, and should not fail with GFP_KERNEL.
With 72-byte spinlock (LOCKDEP):
cpus : 1 2
old: 9k 18k
new: ~2k ~4k

The "alternative command" feature was introduced with sama5d2 SoCs.
Its purpose is to let the hardware i2c controller automatically send the
STOP condition on the i2c bus at the end of a data transfer.
Without this feature, the i2c driver has to write the 'STOP' bit into the
Control Register so the hardware i2c controller is triggered to send the
STOP condition on the bus.
Using the "alternative command" feature requires to set the transfer data
length into the 8bit DATAL field of the Alternative Command Register.
Hence only data transfers up to 255 bytes can take advantage of the
"alternative command" feature. For greater data transfer sizes, the driver
should use the previous implementation, when the "alternative command"
support was not implemented yet.

cros_ec_cmd_xfer returns success status if the command transport
completes successfully, but the execution result is incorrectly ignored.
In many cases, the execution result is assumed to be successful, leading
to ignored errors and operating on uninitialized data.
We've recently introduced the cros_ec_cmd_xfer_status() helper to avoid these
problems. Let's use it.
[Regarding the 'Fixes' tag; there is significant refactoring since the driver's
introduction, but the underlying logical error exists throughout I believe]

The idea for type_check in dev_get_nest_level() was to count the number
of nested devices of the same type (currently, only macvlan or vlan
devices).
This prevented the false positive lockdep warning on configurations such
as:
eth0 <--- macvlan0 <--- vlan0 <--- macvlan1
However, this doesn't prevent a warning on a configuration such as:
eth0 <--- macvlan0 <--- vlan0
eth1 <--- vlan1 <--- macvlan1
In this case, all the locks end up with a nesting subclass of 1, so
lockdep thinks that there is still a deadlock:
- in the first case we have (macvlan_netdev_addr_lock_key, 1) and then
take (vlan_netdev_xmit_lock_key, 1)
- in the second case, we have (vlan_netdev_xmit_lock_key, 1) and then
take (macvlan_netdev_addr_lock_key, 1)
By removing the linktype check in dev_get_nest_level() and always
incrementing the nesting depth, lockdep considers this configuration
valid.
