The introduced function string_escape_mem() is a kind of opposite to
string_unescape. We have several users of such functionality each of
them created custom implementation. The series contains clean up of
test suite, adding new call, and switching few users to use it via %*pE
specifier.
Test suite covers all of existing and most of potential use cases.
This patch (of 11):
The documentation of API belongs to c-file. This patch moves it
accordingly.
There is no functional change.

The previous patch made strnicmp into a wrapper for strncasecmp.
This patch makes all in-tree users of strnicmp call strncasecmp
directly, while still making sure that the strnicmp symbol can be used
by out-of-tree modules. It should be considered a temporary hack until
all in-tree callers have been converted.

We have a large university system in the UK that is experiencing very long
delays modprobing the driver for a specific I/O device. The delay is from
8-10 minutes per device and there are 31 devices in the system. This 4 to
5 hour delay in starting up those I/O devices is very much a burden on the
customer.
There are two causes for requiring a restart/reload of the drivers. First
is periodic preventive maintenance (PM) and the second is if any of the
devices experience a fatal error. Both of these trigger this excessively
long delay in bringing the system back up to full capability.
The problem was tracked down to a very slow IOREMAP operation and the
excessively long ioresource lookup to insure that the user is not
attempting to ioremap RAM. These patches provide a speed up to that
function.
The modprobe time appears to be affected quite a bit by previous activity
on the ioresource list, which I suspect is due to cache preloading. While
the overall improvement is impacted by other overhead of starting the
devices, this drastically improves the modprobe time.
Also our system is considerably smaller so the percentages gained will not
be the same. Best case improvement with the modprobe on our 20 device
smallish system was from 'real 5m51.913s' to 'real 0m18.275s'.
This patch (of 2):
Since the ioremap operation is verifying that the specified address range
is NOT RAM, it will search the entire ioresource list if the condition is
true. To make matters worse, it does this one 4k page at a time. For a
128M BAR region this is 32 passes to determine the entire region does not
contain any RAM addresses.
This patch provides another resource lookup function, region_is_ram, that
searches for the entire region specified, verifying that it is completely
contained within the resource region. If it is found, then it is checked
to be RAM or not, within a single pass.
The return result reflects if it was found or not (-1), and whether it is
RAM (1) or not (0). This allows the caller to fallback to the previous
page by page search if it was not found.

In locate_mem_hole functions, a memory hole is located and added as
kexec_segment. But from the name of locate_mem_hole, it should only take
responsibility of searching a available memory hole to contain data of a
specified size.
So in this patch add a new field 'mem' into kexec_buf, then take that
kexec segment adding code out of locate_mem_hole_top_down and
locate_mem_hole_bottom_up. This make clear of the functionality of
locate_mem_hole just like it declars to do. And by this
locate_mem_hole_callback chould be used later if anyone want to locate a
memory hole for other use.
Meanwhile Vivek suggested opening code function __kexec_add_segment(),
that way we have to retreive ksegment pointer once and it is easy to read.
So just do it in this patch and remove __kexec_add_segment() since no one
use it anymore.

Kill _NSIG_WORDS_is_unsupported_size(), use BUILD_BUG() instead. This
simplifies the code, avoids the nested-externs warnings, and this way we
do not defer the problem to linker.
Also, fix the indentation in _SIG_SET_BINOP() and _SIG_SET_OP().
Note: this patch assumes that the code like "if (0) BUILD_BUG();" is
valid. If not (say __compiletime_error() is not defined and thus
__compiletime_error_fallback() uses a negative array) we should fix
BUILD_BUG() and/or BUILD_BUG_ON_MSG(). This code should be fine by
definition, this is the documented purpose of BUILD_BUG().

This adds the missing validation code to avoid the use of nat/masq from
non-nat chains. The validation assumes two possible configuration
scenarios:
1) Use of nat from base chain that is not of nat type. Reject this
configuration from the nft_*_init() path of the expression.
2) Use of nat from non-base chain. In this case, we have to wait until
the non-base chain is referenced by at least one base chain via
jump/goto. This is resolved from the nft_*_validate() path which is
called from nf_tables_check_loops().
The user gets an -EOPNOTSUPP in both cases.

The old code has problems with the Dell MST monitors due to some
assumptions I made that weren't true.
I initially thought the Virtual Channel Payload IDs had to be in
the DPCD table in ascending order, however it appears that assumption
is bogus.
The old code also assumed it was possible to insert a member
into the table and it would move other members up, like it does
when you remove table entries, however reality has shown this
isn't true.
So the new code allocates VCPIs separate from entries in the payload
tracking table, and when we remove an entry from the DPCD table,
I shuffle the tracking payload entries around in the struct.
This appears to make VT switch more robust (still not perfect)
with an MST enabled Dell monitor.

of the trampoline logic.
The trampoline logic of 3.17 required a descriptor for every function
that is registered to be traced and uses a trampoline. Currently,
only the function graph tracer uses a trampoline, but if you were
to trace all 32,000 (give or take a few thousand) functions with the
function graph tracer, it would create 32,000 descriptors to let us
know that there's a trampoline associated with it. This takes up a bit
of memory when there's a better way to do it.
The redesign now reuses the ftrace_ops' (what registers the function graph
tracer) hash tables. The hash tables tell ftrace what the tracer
wants to trace or doesn't want to trace. There's two of them: one
that tells us what to trace, the other tells us what not to trace.
If the first one is empty, it means all functions should be traced,
otherwise only the ones that are listed should be. The second hash table
tells us what not to trace, and if it is empty, all functions may be
traced, and if there's any listed, then those should not be traced
even if they exist in the first hash table.
It took a bit of massaging, but now these hashes can be used to
keep track of what has a trampoline and what does not, and allows
the ftrace accounting to work. Now we can trace all functions when using
the function graph trampoline, and avoid needing to create any special
descriptors to hold all the functions that are being traced.

know that there's a trampoline associated with it. This takes up a
bit of memory when there's a better way to do it.
The redesign now reuses the ftrace_ops' (what registers the function
graph tracer) hash tables. The hash tables tell ftrace what the
tracer wants to trace or doesn't want to trace. There's two of them:
one that tells us what to trace, the other tells us what not to trace.
If the first one is empty, it means all functions should be traced,
otherwise only the ones that are listed should be. The second hash
table tells us what not to trace, and if it is empty, all functions
may be traced, and if there's any listed, then those should not be
traced even if they exist in the first hash table.
It took a bit of massaging, but now these hashes can be used to keep
track of what has a trampoline and what does not, and allows the
ftrace accounting to work. Now we can trace all functions when using
the function graph trampoline, and avoid needing to create any special
descriptors to hold all the functions that are being traced"

Pull networking fixes from David Miller:
"This set fixes a bunch of fallout from the changes that went in during
this merge window, particularly:
- Fix fsl_pq_mdio (Claudiu Manoil) and fm10k (Pranith Kumar) build
failures.
- Several networking drivers do atomic_set() on page counts where
that's not exactly legal. From Eric Dumazet.
- Make __skb_flow_get_ports() work cleanly with unaligned data, from
Alexander Duyck.

limits the previous code used to enforce, reintroduce in a way that
at the same time doesn't compromise bulk dequeue opportunities.
From Jesper Dangaard Brouer.
- macvlan receive path unnecessarily hops through a softirq by using
netif_rx() instead of netif_receive_skb(). From Jason Baron"

This branch contains bug fixes and new features for the devicetree code.
Most of the changes are either new testcases for the selftest code or
documentation changes. The most notable change is the addition of a
phandle resolver for use when grafting in a second device tree blob into
the core tree. The resolver isn't currently used by anything other than
the selftest module, but it will be used to support device tree
overlays; probably in the v3.19 timeframe.
Also note that I've moved my normal tree from git.secretlab.ca to
git.kernel.org.

- ALSA core
- One major change is the support of nonatomic PCM operations.
This allows the trigger and other callbacks to call schedule(),
which would be useful for mailbox type communications. Already
some drivers (Digigram ones) have been converted to use together
with threaded irqs as an example.
- Improvement / fixes of DSD PCM format support
- HD-audio
- Large volume of rewrites are found in Realtek codec driver for
converting Dell and HP quirks to generic forms.
- Inverted dmic code cleanup from David.
- Realtek COEF access has been optimized.
- Now HD-audio jack infrastructure allows multiple callbacks, which
fixes / simplifies the jack-dependent power controls on STAC/IDT
and VIA codecs.
- Many additional device-specific fixups as usual
- A few deadcode cleanups, CA0132 code cleanup, etc.
- ASoC
- More componentization work from Lars-Peter, this time mainly
cleaning up the suspend and bias level transition callbacks.
- Real system support for the Intel drivers and a bunch of fixes
and enhancements for the associated CODEC drivers, this is going
to need a lot quirks over time due to the lack of any firmware
description of the boards.
- Jack detect support for simple card from Dylan Reid.
- A bunch of small fixes and enhancements for the Freescale
drivers.
- New drivers for Analog Devices SSM4567, Cirrus Logic CS35L32,
Everest Semiconductor ES8328 and Freescale cards using the ASRC
in newer i.MX processors.
- A few simple-card fixes, mostly cleanups but also a fix for

- Misc
- Virtuoso / Oxygen updates by Clemens

- Conversion of kernel messages to standard dev_*() in ctxfi

Pull percpu updates from Tejun Heo:
"A lot of activities on percpu front. Notable changes are...
- percpu allocator now can take @gfp. If @gfp doesn't contain
GFP_KERNEL, it tries to allocate from what's already available to
the allocator and a work item tries to keep the reserve around
certain level so that these atomic allocations usually succeed.
This will replace the ad-hoc percpu memory pool used by
blk-throttle and also be used by the planned blkcg support for
writeback IOs.
Please note that I noticed a bug in how @gfp is interpreted while
preparing this pull request and applied the fix 6ae833c7fe0c
("percpu: fix how @gfp is interpreted by the percpu allocator")
just now.
- percpu_ref now uses longs for percpu and global counters instead of
ints. It leads to more sparse packing of the percpu counters on
64bit machines but the overhead should be negligible and this
allows using percpu_ref for refcnting pages and in-memory objects
directly.
- The switching between percpu and single counter modes of a
percpu_ref is made independent of putting the base ref and a
percpu_ref can now optionally be initialized in single or killed
mode. This allows avoiding percpu shutdown latency for cases where
the refcounted objects may be synchronously created and destroyed
in rapid succession with only a fraction of them reaching fully
operational status (SCSI probing does this when combined with
blk-mq support). It's also planned to be used to implement forced
single mode to detect underflow more timely for debugging.
There's a separate branch percpu/for-3.18-consistent-ops which cleans
up the duplicate percpu accessors. That branch causes a number of
conflicts with s390 and other trees. I'll send a separate pull
request w/ resolutions once other branches are merged"

"AHCI is getting per-port irq handling and locks for better
scalability. The gain is not huge but measureable with multiple high

threaded IRQ handling seems negligible for AHCI and it likely will
revert to non-threaded handling soon.
Another noteworthy change is George Spelvin's "libata: Un-break ATA
blacklist". During 3.17 devel cycle, the libata blacklist glob
matching got generalized and rewritten; unfortunately, the patch
forgot to swap arguments to match the new match function and ended up
breaking blacklist matching completely. It got noticed only a couple
days ago so it couldn't make for-3.17-fixes either. :(
Other than the above two, nothing too interesting - the usual cleanup
churns and device-specific changes"
