[ Upstream commit 1aaa557b2db95c9506ed0981bc34505c32d6b62b ]
'make randconfig' can produce a .config file with
"CONFIG_MEMORY_RESERVE=" (no value) since it has no default.
When a subsequent 'make all' is done, kconfig restarts the config
and prompts for a value for MEMORY_RESERVE. This breaks
scripting/automation where there is no interactive user input.
Add a default value for MEMORY_RESERVE. (Any integer value will
work here for kconfig.)
Fixes a kconfig warning:
.config:214:warning: symbol value '' invalid for MEMORY_RESERVE
* Restart config...

Today the sh code allocates memory the first time a process uses
the fpu. If that memory allocation fails, kill the affected task
with force_sig(SIGKILL) rather than do_group_exit(SIGKILL).
Calling do_group_exit from an exception handler can potentially lead
to dead locks as do_group_exit is not designed to be called from
interrupt context. Instead use force_sig(SIGKILL) to kill the
userspace process. Sending signals in general and force_sig in
particular has been tested from interrupt context so there should be
no problems.

[ Upstream commit e7e1e880b114ca640a2f280b0d5d38aed98f98c6 ]
Before the `callback_result` callback was introduced drivers coded their
invocation to the callback in a similar way to:
if (cb->callback) {
spin_unlock(&dma->lock);
cb->callback(cb->callback_param);
spin_lock(&dma->lock);
}
With the introduction of `callback_result` two helpers where introduced to
transparently handle both types of callbacks. And drivers where updated to
look like this:
if (dmaengine_desc_callback_valid(cb)) {
spin_unlock(&dma->lock);
dmaengine_desc_callback_invoke(cb, ...);
spin_lock(&dma->lock);
}
dmaengine_desc_callback_invoke() correctly handles both `callback_result`
and `callback`. But we forgot to update the dmaengine_desc_callback_valid()
function to check for `callback_result`. As a result DMA descriptors that
use the `callback_result` rather than `callback` don't have their callback
invoked by drivers that follow the pattern above.
Fix this by checking for both `callback` and `callback_result` in
dmaengine_desc_callback_valid().

set/reset for each bit. Clearing by PCL_RCV_INTX_ALL_MASK should be
removed.
INTX status fields in PCL_RCV_INTX register only indicates each INTX
interrupt status, so the handler can't clear by writing 1 to the field.

I have a ST1633 touch controller which fails to probe due to a timeout
waiting for the controller to become ready. Increasing the minimum
delay to 100ms ensures that the probe sequence completes successfully.
The ST1633 datasheet says nothing about the maximum delay here and the
ST1232 I2C protocol document says "wait until" with no notion of a
timeout.
Since this only runs once during probe, being generous with the timout
seems reasonable and most likely the device will become ready
eventually.
(It may be worth noting that I saw this issue with a PREEMPT_RT patched

using CRSSVE flag for handling CRS responses.
PCI_EXP_RTCTL_CRSSVE flag is stored only in emulated config space buffer

events on its own
- do not call drm_kms_helper_hotplug_event() unless mode_config.funcs

_nfs4_pnfs_v3/v4_ds_connect do
some work
smp_wmb
ds->ds_clp = clp;
And nfs4_ff_layout_prepare_ds currently does
smp_rmb
if(ds->ds_clp)
...
This patch places the smp_rmb after the if. This ensures that following
reads only happen once nfs4_ff_layout_prepare_ds has checked that data
has been properly initialized.

If the directory changed while we were revalidating the dentry, then
don't update the dentry verifier. There is no value in setting the
verifier to an older value, and we could end up overwriting a more up to
date verifier from a parallel revalidation.

[ Upstream commit eea413308f2e6deb00f061f18081a53f3ecc8cc6 ]
Both NFSv3 and NFSv2 generate their change attribute from the ctime
value that was supplied by the server. However the problem is that there
are plenty of servers out there with ctime resolutions of 1ms or worse.
In a modern performance system, this is insufficient when trying to
decide which is the most recent set of attributes when, for instance, a
READ or GETATTR call races with a WRITE or SETATTR.
For this reason, let's revert to labelling the NFSv2/v3 change
attributes as NFS4_CHANGE_TYPE_IS_UNDEFINED. This will ensure we protect
against such races.

ebu_nand_probe() read the value of u32 variable "cs" from the device
firmware description and used it as the index for array ebu_host->cs
that can contain MAX_CS (2) elements at most. That could result in
a buffer overflow and various bad consequences later.
Fix the potential buffer overflow by restricting values of "cs" with
MAX_CS in probe.
