"This series is a second round of target fixes for v3.7-rc4 that have
come into target-devel over the last days, and are important enough to
be applied ASAP.
All are being CC'ed to stable. The most important two are:
- target: Re-add explict zeroing of INQUIRY bounce buffer memory to
fix a regression for handling zero-length payloads, a bug that went
during v3.7-rc1, and hit >= v3.6.3 stable. (nab + paolo)
- iscsi-target: Fix a long-standing missed R2T wakeup race in TX
thread processing when using a single queue slot. (Roland)
Thanks to Roland & PureStorage team for helping to track down this
long standing race with iscsi-target single queue slot operation.
Also, the tcm_fc(FCoE) regression bug that was observed recently with
-rc2 code has also been resolved with the cancel_delayed_work() return
bugfix (commit c0158ca64da5: "workqueue: cancel_delayed_work() should
return %false if work item is idle") now in -rc3. Thanks again to Yi

iscsi-target: Fix missed wakeup race in TX thread
The sleeping code in iscsi_target_tx_thread() is susceptible to the classic
missed wakeup race:
- TX thread finishes handle_immediate_queue() and handle_response_queue(),
thinks both queues are empty.
- Another thread adds a queue entry and does wake_up_process(), which does
nothing because the TX thread is still awake.
- TX thread does schedule_timeout() and sleeps forever.
In practice this can kill an iSCSI connection if for example an initiator
does single-threaded writes and the target misses the wakeup window when
queueing an R2T; in this case the connection will be stuck until the
initiator loses patience and does some task management operation (or kills
the connection entirely).
Fix this by converting to wait_event_interruptible(), which does not
suffer from this sort of race.

KVM: x86: fix vcpu->mmio_fragments overflow
After commit b3356bf0dbb349 (KVM: emulator: optimize "rep ins" handling),
the pieces of io data can be collected and write them to the guest memory
or MMIO together
Unfortunately, kvm splits the mmio access into 8 bytes and store them to
vcpu->mmio_fragments. If the guest uses "rep ins" to move large data, it
will cause vcpu->mmio_fragments overflow
Actually, we can use one mmio_fragment to store a large mmio access then
split it when we pass the mmio-exit-info to userspace. After that, we only
need two entries to store mmio info for the cross-mmio pages access
xen/mmu: Use Xen specific TLB flush instead of the generic one.
As Mukesh explained it, the MMUEXT_TLB_FLUSH_ALL allows the
hypervisor to do a TLB flush on all active vCPUs. If instead
we were using the generic one (which ends up being xen_flush_tlb)
we end up making the MMUEXT_TLB_FLUSH_LOCAL hypercall. But
before we make that hypercall the kernel will IPI all of the
vCPUs (even those that were asleep from the hypervisor
perspective). The end result is that we needlessly wake them
up and do a TLB flush when we can just let the hypervisor
do it correctly.
This patch gives around 50% speed improvement when migrating
idle guest's from one host to another.

Due to the SMP nature of some of the chips, which have per CPU
registers, the driver does not use the generic irq_gc_mask_set_bit() &
irq_gc_mask_clr_bit() functions, which only support a single register.
The driver has its own implementation of these functions, which can
pick the correct register depending on the CPU being used. The
functions do however use the gc->mask_cache value.
The call to irq_setup_generic_chip() was passing
IRQ_GC_INIT_MASK_CACHE, which caused the gc->mask_cache to be
initialized to the contents of some random register. This resulted in
unexpected interrupts been delivered from random GPIO lines.

loop: Make explicit loop device destruction lazy
xfstests has always had random failures of tests due to loop devices
failing to be torn down and hence leaving filesytems that cannot be
unmounted. This causes test runs to immediately stop.
Over the past 6 or 7 years we've added hacks like explicit unmount
-d commands for loop mounts, losetup -d after unmount -d fails, etc,
but still the problems persist. Recently, the frequency of loop
related failures increased again to the point that xfstests 259 will
reliably fail with a stray loop device that was not torn down.
That is despite the fact the test is above as simple as it gets -
loop 5 or 6 times running mkfs.xfs with different paramters:
And losteup -d $lofile is failing with EBUSY on 1-3 of these loops
every time the test is run.
Turns out that blkid is running simultaneously with losetup -d, and
so it sees an elevated reference count and returns EBUSY. But why
is blkid running? It's obvious, isn't it? udev has decided to try
and find out what is on the block device as a result of a creation
notification. And it is racing with mkfs, so might still be scanning
the device when mkfs finishes and we try to tear it down.
So, make losetup -d force autoremove behaviour. That is, when the
last reference goes away, tear down the device. xfstests wants it
*gone*, not causing random teardown failures when we know that all
the operations the tests have specifically run on the device have
completed and are no longer referencing the loop device.

Nix ran into this when using the journal_async_commit mount

gpio/omap: fix off-mode bug: clear debounce settings on free/reset
This change was originally titled "gpio/omap: fix off-mode bug: clear debounce
clock enable mask on free/reset". The title has been updated slightly to
reflect (what should be) the final fix.
When a GPIO is freed or shutdown, we need to ensure that any debounce settings
are cleared and if the GPIO is the only GPIO in the bank that is currently
using debounce, then disable the debounce clock as well to save power.
Currently, the debounce settings are not cleared on a GPIO free or shutdown and
so during a context restore on subsequent off-mode transition, the previous
debounce values are restored from the shadow copies (bank->context.debounce*)
leading to mismatch state between driver state and hardware state.
which was leaving the GPIO debounce settings in a confused state. If that GPIO
bank is subsequently used with off-mode enabled, bogus state would be restored,
leaving GPIO debounce enabled which then prevented the CORE powerdomain from
transitioning.
To fix this, introduce a new function called _clear_gpio_debounce() to clear
any debounce settings when the GPIO is freed or shutdown. If this GPIO is the
last debounce-enabled GPIO in the bank, the debounce will also be cut.
Please note that we cannot use _gpio_dbck_disable() to disable the debounce
clock because this has been specifically created for the gpio suspend path
and is intended to shutdown the debounce clock while debounce is enabled.
Special thanks to Kevin Hilman for root causing the bug. This fix is a
collaborative effort with inputs from Kevin Hilman, Grazvydas Ignotas and
Santosh Shilimkar.
Testing:
- This has been unit tested on an OMAP3430 Beagle board, by requesting a gpio,
enabling debounce and then freeing the gpio and checking the register
contents, the saved register context and the debounce clock state.
- Kevin Hilman tested on 37xx/EVM board which configures GPIO debounce for the
ads7846 touchscreen in its board file using the above sequence, and so was
failing off-mode tests in dynamic idle. Verified that off-mode tests are
passing with this patch.
