The conversion to dma_map_sg left a few loose ends. This change
ties up those loose ends.
1. Settings the DMA mask is mandatory on 64 bit even though it
is optional on 32 bit. Set the mask so that DMA space is always
in the lower 32 bit range of data on both platforms.

Hi Mark,
This patchset fixes broken lpass-platform driver in v4.9-rc1, and also

There is also a cleanup patch in this series just to tidy up the code

This patch cleans up usage of wrdma_ch and rdma_ch variables into a

I still think we should kill struct kthread in its current form, but this
needs cleanups outside of kthread.c.
So make it kmalloc'ed for now to avoid the problems with stack corruption,
for example the crashed kthread will likely OOPS again because its .exited
was destroyed by rewind_stack_do_exit
This reverts commit 23196f2e5f5d810578a772785807dcdc2b9fdce9.
After the previous change struct kthread can't go away, no need to pin
the stack.

Currently, we assume that a system has multiple last level caches only if

A Mutex lock in cros_ec_cmd_xfer which may be held by frozen

This series adds an FPGA manager for Altera cyclone FPGAs
that can program them using an spi port and a couple of gpios, using
Alteras passive serial protocol.
Changes from v1:
- Changed the name from cyclone-spi-fpga-mgr to cyclone-ps-spi-fpga-mgr
This name change was requested by Alan Tull, to

Add a program feature so we can upload and run programs for lightbar

Some devices might want to turn off the lightbar if e.g. the
system turns the screen off due to idleness. This prevents the
kernel from going through its normal suspend/resume pathways.

cyclone-ps-spi loads FPGA firmware over spi, using the "passive serial"
interface on Altera Cyclone FPGAS.
This is one of the simpler ways to set up an FPGA at runtime.
The signal interface is close to unidirectional spi with lsb first.

When an ext4 fs is bogged down by a lot of metadata IOs (in the
reported case, it was deletion of millions of files, but any massive
amount of journal writes would do), after the journal is filled up,
tasks which try to access the filesystem and aren't currently
performing the journal writes end up
We sometimes end up propagating IO blocking through mutexes; however,
because there currently is no way of annotating mutex sleeps as
iowait, there are cases where iowait and /proc/stat:procs_blocked
report misleading numbers obscuring the actual state of the system.

ioremaped addresses are not linearly mapped so the physical
address can not be figured out via __pa. More generally, there
is no guarantee that backing value of an ioremapped address
is a physical address at all. The value here is only used
for debugging so just drop the call to __pa on the ioremap
Hello,
When there's heavy metadata operation traffic on ext4, the journal
gets filled soon and majority of filesystem users end up blocking on
journal->j_checkpoint_mutex with a stacktrace similar to the
following.
[] __jbd2_log_wait_for_space+0xb8/0x1d0
[] add_transaction_credits+0x286/0x2a0
Now that IO schedule accounting is done inside __schedule(),
io_schedule() can be split into three steps - prep, schedule, and
finish - where the schedule part doesn't need any special annotation.
This allows marking a sleep as iowait by simply wrapping an existing
blocking function with io_schedul
For an interface to support blocking for IOs, it must call
io_schedule() instead of schedule(). This makes it tedious to add IO
blocking to existing interfaces as the switching between schedule()
and io_schedule() is often buried deep.
As we already have a way to mark the task as IO scheduling, t
