Previously, pending interrupts in tscadc were causing HW_PEN interrupt,
needed for wake from DS0, to get disabled immediately by IRQ handler
after being enabled. Flush all pending interrupts in suspend handler
before enabling HW_PENi interrupt so that this no longer happens and
board is able to wake from DS0 on a touch event.Signed-off-by: Dave Gerlach

CPSW driver TX and RX interrupt handling is not optimal. The driver handles
both irq's together and relies on RX NAPI to proces the TX packet. Lets
seperate the interrupt handling and convert the TX completion to NAPI as
well.With these changes the network perfromance shoots up by almost 40 %
for UDP. For TCP we also we get pretty good boost.Signed-off-by: Santosh Shilimkar

Update omapdss/dpi driver to set the state of the pins to:
- "default on enable
- "sleep" on disableThe disable and enable functions are called from a PM hook within
omapdss so the sleep and default states will be used with suspend
and resume, respectively.By optionally putting the pins into sleep state in the suspend callback
we can accomplish two things.
- minimize current leakage from pins and thus save power,
- prevent the IP from driving pins output in an uncontrolled manner,
which may happen if the power domain drops the domain regulator.Signed-off-by: Dave Gerlach

commit ee291e63293146db64668e8d65eb35c97e8324f4 upstream.
When creating network portals rapidly, such as when restoring a
configuration, LIO's code to reuse existing portals can return a false
negative if the thread hasn't run yet and set np_thread_state to
ISCSI_NP_THREAD_ACTIVE. This causes an error in the network stack
when attempting to bind to the same address/port.This patch sets NP_THREAD_ACTIVE before the np is placed on g_np_list,
so even if the thread hasn't run yet, iscsit_get_np will return the
existing np.Also, convert np_lock -> np_mutex + hold across adding new net portal
to g_np_list to prevent a race where two threads may attempt to create
the same network portal, resulting in one of them failing.(nab: Add missing mutex_unlocks in iscsit_add_np failure paths)

commit 4a4caa29f1abcb14377e05d57c0793d338fb945d upstream.
This patch addresses an traditional iscsi-target fabric ack starvation
issue where iscsit_allocate_cmd() -> percpu_ida_alloc_state() ends up
hitting slow path percpu-ida code, because iscsit_ack_from_expstatsn()
is expected to free ack'ed tags after tag allocation.This is done to take into account the tags waiting to be acknowledged
and released in iscsit_ack_from_expstatsn(), but who's number are not
directly limited by the CmdSN Window queue_depth being enforced by
the target.So that said, this patch bumps up the pre-allocated number of
per session tags to:(max(queue_depth, ISCSIT_MIN_TAGS) * 2) + ISCSIT_EXTRA_TAGS
for good measure to avoid the percpu_ida_alloc_state() slow path.

commit dcaf9aed995c2b2a49fb86bbbcfa2f92c797ab5d upstream.
Bfa driver crash is observed while pushing the firmware on to chinook
quad port card due to uninitialized bfi_image_ct2 access which gets
initialized only for CT2 ASIC based cards after request_firmware().
For quard port chinook (CT2 ASIC based), bfi_image_ct2 is not getting
initialized as there is no check for chinook PCI device ID before
request_firmware and instead bfi_image_cb is initialized as it is the
default case for card type check.This patch includes changes to read the right firmware for quad port chinook.

[ Upstream commit cefe0078eea52af17411eb1248946a94afb84ca5 ]
This patch removes grant transfer releasing code from netfront, and uses
gnttab_end_foreign_access to end grant access since
gnttab_end_foreign_access_ref may fail when the grant entry is
currently used for reading or writing.* clean up grant transfer code kept from old netfront(2.6.18) which grants
pages for access/map and transfer. But grant transfer is deprecated in current
netfront, so remove corresponding release code for transfer.* fix resource leak, release grant access (through gnttab_end_foreign_access)
and skb for tx/rx path, use get_page to ensure page is released when grant
access is completed successfully.Xen-blkfront/xen-tpmfront/xen-pcifront also have similar issue, but patches
for them will be created separately.V6: Correct subject line and commit message.
V5: Remove unecessary change in xennet_end_access.
V4: Revert put_page in gnttab_end_foreign_access, and keep netfront change in
single patch.V3: Changes as suggestion from David Vrabel, ensure pages are not freed untill
grant acess is ended.V2: Improve patch comments.

commit ef71ec00002d92a08eb27e9d036e3d48835b6597 upstream.
The code that handles overlapping extents that we've just read back in from disk
was depending on the behaviour of the code that handles overlapping extents as
we're inserting into a btree node in the case of an insert that forced an
existing extent to be split: on insert, if we had to split we'd also insert a
new extent to represent the top part of the old extent - and then that new
extent would get written out.The code that read the extents back in thus not bother with splitting extents -
if it saw an extent that ovelapped in the middle of an older extent, it would
trim the old extent to only represent the bottom part, assuming that the
original insert would've inserted a new extent to represent the top part.I still haven't figured out _how_ it can happen, but I'm now pretty convinced
(and testing has confirmed) that there's some kind of an obscure corner case
(probably involving extent merging, and multiple overwrites in different sets)
that breaks this. The fix is to change the mergesort fixup code to split extents
itself when required.Signed-off-by: Kent Overstreet
