Add support for a legacy mapping where irq = (hwirq - first_hwirq + first_irq)
so that a controller driver can allocate a fixed range of irq_descs and use
a simple calculation to translate back and forth between linux and hw irq
numbers. This is needed to use an irq_domain with many of the ARM interrupt
controller drivers that manage their own irq_desc allocations. Ultimately
the goal is to migrate those drivers to use the linear revmap, but doing it
this way allows each driver to be converted separately which makes the
migration path easier.
This patch generalizes the IRQ_DOMAIN_MAP_LEGACY method to use
(first_irq-first_hwirq) as the offset between hwirq and linux irq number,
and adds checks to make sure that the hwirq number does not exceed range
assigned to the controller.

Each revmap type has different arguments for setting up the revmap.
This patch splits up the generator functions so that each revmap type
can do its own setup and the user doesn't need to keep track of how
each revmap type handles the arguments.
This patch also adds a host_data argument to the generators. There are
cases where the host_data pointer will be needed before the function returns.
ie. the legacy map calls the .map callback for each irq before returning.
v2: - Add void *host_data argument to irq_domain_add_*() functions
- fixed failure to compile
- Moved IRQ_DOMAIN_MAP_* defines into irqdomain.c

This patch drops the powerpc-specific irq_map table and replaces it with
directly using the irq_alloc_desc()/irq_free_desc() interfaces for allocating
and freeing irq_desc structures.
This patch is a preparation step for generalizing the powerpc-specific virq
infrastructure to become irq_domains.
As part of this change, the irq_big_lock is changed to a mutex from a raw
spinlock. There is no longer any need to use a spin lock since the irq_desc
allocation code is now responsible for the critical section of finding
an unused range of irq numbers.
The radix lookup table is also changed to store the irq_data pointer instead
of the irq_map entry since the irq_map is removed. This should end up being
functionally equivalent since only allocated irq_descs are ever added to the
radix tree.
v5: - Really don't ever allocate virq 0. The previous version could still
do it if hint == 0
- Respect irq_virq_count setting for NOMAP. Some NOMAP domains cannot
use virq values above irq_virq_count.
- Use numa_node_id() when allocating irq_descs. Ideally the API should
obtain that value from the caller, but that touches a lot of call sites
so will be deferred to a follow-on patch.
- Fix irq_find_mapping() to include irq numbers lower than
NUM_ISA_INTERRUPTS. With the switch to irq_alloc_desc*(), the lowest
possible allocated irq is now returned by arch_probe_nr_irqs().
v4: - Fix incorrect access to irq_data structure in debugfs code
- Don't ever allocate virq 0

This patch drops the powerpc-specific irq_host structures and uses the common
irq_domain strucutres defined in linux/irqdomain.h. It also fixes all
the users to use the new structure names.
Renaming irq_host to irq_domain has been discussed for a long time, and this
patch is a step in the process of generalizing the powerpc virq code to be
usable by all architecture.
An astute reader will notice that this patch actually removes the irq_host
structure instead of renaming it. This is because the irq_domain structure
already exists in include/linux/irqdomain.h and has the needed data members.

Part of the series to unify the irq remapping mechanisms in the

are identical.
Where they differ, I've chose to use the powerpc names since there is

This set of changes are fixing various section mismatch warnings which

Some code - especially the crypto layer - wants to use the x86
FP/MMX/AVX register set in what may be interrupt (typically softirq)
context.
That *can* be ok, but the tests for when it was ok were somewhat
suspect. We cannot touch the thread-specific status bits either, so
we'd better check that we're not going to try to save FP state or
anything like that.
Now, it may be that the TS bit is always cleared *before* we set the
USEDFPU bit (and only set when we had already cleared the USEDFP
before), so the TS bit test may actually have been sufficient, but it
certainly was not obviously so.
So this explicitly verifies that we will not touch the TS_USEDFPU bit,
and adds a few related sanity-checks. Because it seems that somehow
AES-NI is corrupting user FP state. The cause is not clear, and this
patch doesn't fix it, but while debugging it I really wanted the code to
be more obviously correct and robust.

Merged back the fix for Acer Aspire 6935 with ALC889 codec.
The fix commit was based on 3.2 kernel so that it can be applied to
stable kernel cleanly.
Since 3.2 kernel, the driver starts trying to assign the multi-io DACs
before the speaker, thus it assigns DAC2/3 for multi-io and DAC4 for
the speaker for a standard laptop setup like a HP, a speaker, a mic-in
and a line-in. However, on Acer Aspire 6935, it seems that the
speaker pin 0x14 must be connected with either DAC1 or 2; otherwise it
results in silence by some reason, although the codec itself allows
the routing to DAC3/4.
As a workaround, the connection list of each pin is reduced to be
mapped to either only DAC1/2 or DAC3/4, so that the compatible
assignment as in kernel 3.1 is achieved.

VT1705 codec has two ADCs where the secondary ADC has no MUX but only
a fixed connection to the mic pin. This confused the driver and it
tries always overriding the input-source selection by assumption of
the existing MUX for the secondary ADC, resulted in resetting the
input-source at each time PM (including power-saving) occurs.
The fix is simply to check the existence of MUX for secondary ADCs in
the initialization code.

It's useful to print the error code when a called function fails so a
diagnosis of why it failed is possible. In this case, it fails because
we try to register some data for the wl12xx driver, but as the driver
is not configured, a stub function is used which simply returns -ENOSYS.
Let's do the simple thing for -rc and print the error code.
Also, the return code from platform_register_device() at each of these
sites was not being checked. Add some checking, and again print the
error code.
This should be fixed properly for the next merge window so we don't
issue error messages merely because a driver is not configured.

Again, as for omap2_hsmmc_init(), these functions are callable at

This makes sdp3430_twl_gpio_setup() callable at runtime, and prevents
it being marked with an __init annotation.
As it calls omap2_hsmmc_init() unconditionally, the only resolution to
this warning is to remove the __init markings from omap2_hsmmc_init()
and its called functions. This addresses the functions in hsmmc.c.

Found by review.
omap4_sdp4430_wifi_mux_init() is called by an __init marked function,
and only calls omap_mux_init_gpio() and omap_mux_init_signal() which
are both also an __init marked functions.
The only reason this doesn't issue a warning is because the compiler
inlines omap4_sdp4430_wifi_mux_init() into omap4_sdp4430_wifi_init().
So, lets add the __init annotation to ensure this remains safe should
the compiler choose not to inline.

On my OMAP4 platform, I'm getting this error message repeated several
times at boot:
omap_vc_i2c_init: I2C config for all channels must match.
omap_vc_i2c_init: I2C config for all channels must match.
This doesn't help identify what the problem is. Fix this message to
be more informative:
omap_vc_i2c_init: I2C config for vdd_iva does not match other channels (0).
omap_vc_i2c_init: I2C config for vdd_mpu does not match other channels (0).
This allows us to identify which voltage domains have a problem, and
what the I2C configuration state (a boolean, i2c_high_speed) setting
being used actually is.
From this we find that omap4_core_pmic has i2c_high_speed false, but
omap4_iva_pmic and omap4_mpu_pmic both have it set true.

While testing on my OMAP3430 platform, this error message was emitted:

Trying to find this message was difficult because it was wrapped across
several lines. It also mis-spells "required", doesn't read very well,
and has spaces lacking. Let's replace it with a more concise:
omap_vc_init_channel: No PMIC info for vdd_core

Says Jens:
"Time to push off some of the pending items. I really wanted to wait
until we had the regression nailed, but alas it's not quite there yet.
But I'm very confident that it's "just" a missing expire on exit, so
fix from Tejun should be fairly trivial. I'm headed out for a week on
the slopes.
- Killing the barrier part of mtip32xx. It doesn't really support
barriers, and it doesn't need them (writes are fully ordered).
- A few fixes from Dan Carpenter, preventing overflows of integer
multiplication.
- A fixup for loop, fixing a previous commit that didn't quite solve
the partial read problem from Dave Young.
- A bio integer overflow fix from Kent Overstreet.
- Improvement/fix of the door "keep locked" part of the cdrom shared
code from Paolo Benzini.
- A few cfq fixes from Shaohua Li.
- A fix for bsg sysfs warning when removing a file it did not create
from Stanislaw Gruszka.
- Two fixes for floppy from Vivek, preventing a crash.
- A few block core fixes from Tejun. One killing the over-optimized
ioc exit path, cleaning that up nicely. Two others fixing an oops
on elevator switch, due to calling into the scheduler merge check
code without holding the queue lock."

removed ioc_lock depth lockdep annoation along with locking
optimization; however, while recursing from put_io_context() is no
longer possible, ioc_release_fn() may still end up putting the last
reference of another ioc through elevator, which wlil grab ioc->lock
triggering spurious (as the ioc is always different one) A-A deadlock
warning.
As this can only happen one time from ioc_release_fn(), using non-zero
subclass from ioc_release_fn() is enough. Use subclass 1.

link types. This required a multi-faceted fix to cure the originally
noted case (Infiniband), because IPoIB was lying about it's actual
hard header length. Thanks to Eric Dumazet, Roland Dreier, and
others.
2) Fix build failure when INET_UDP_DIAG is built in and ipv6 is modular.

3) Off by ones and other bug fixes in netprio_cgroup from Neil Horman.
4) ipv4 TCP reset generation needs to respect any network interface
binding from the socket, otherwise route lookups might give a

Graf.
6) Fix SKB under-allocation bug in sh_eth, from Yoshihiro Shimoda.
7) Revert skge PCI mapping changes that are causing crashes for some
folks, from Stephen Hemminger.
8) IPV4 route lookups fill in the wildcarded fields of the given flow
lookup key passed in, which is fine most of the time as this is
exactly what the caller's want. However there are a few cases that
want to retain the original flow key values afterwards, so handle
those cases properly. Fix from Julian Anastasov.

Commit 653241 (net: RFC3069, private VLAN proxy arp support) changed
the behavior of arp proxy to send arp replies back out on the interface
the request came in even if the private VLAN feature is disabled.
Previously we checked rt->dst.dev != skb->dev for in scenarios, when
proxy arp is enabled on for the netdevice and also when individual proxy
neighbour entries have been added.
This patch adds the check back for the pneigh_lookup() scenario.

So we delay the allocation till the priority is set through cgroup,
and this makes skb_update_priority() faster when it's not set.
