In debugging an application that receives -ENOMEM from ib_reg_mr(), I
found that ib_umem_get() can fail because the pinned_vm count has
wrapped causing it to always be larger than the lock limit even with
RLIMIT_MEMLOCK set to RLIM_INFINITY.
The wrapping of pinned_vm occurs because the process that calls
ib_reg_mr() will have its mm->pinned_vm count incremented. Later a
different process with a different mm_struct than the one that
allocated the ib_umem struct ends up releasing it which results in
decrementing the new processes mm->pinned_vm count past zero and
wrapping.
I'm not entirely sure what circumstances cause a different process to
release the ib_umem than the one that allocated it but the kernel
stack trace of the freeing process from my situation looks like the
following:
Call Trace:
[<ffffffff814d64b1>] dump_stack+0x19/0x1b
[<ffffffffa0b522a5>] ib_umem_release+0x1f5/0x200 [ib_core]

The following patch fixes the issue by storing the pid struct of the
process that calls ib_umem_get() so that ib_umem_release and/or
ib_umem_account() can properly decrement the pinned_vm count of the
correct mm_struct.

When ending a bi-directionional SCSI request, blk_finish_request()
cleans up and frees the request, but scsi_release_bidi_buffers() tries
to indirect through the request to find it's data buffers. This causes

This patch introduces the driver for the RTC in the Allwinner A31 and
A23 SoCs.
Unlike the RTC found in A10/A20 SoCs, which was part of the timer, the
RTC in A31/A23 are a separate hardware block, which also contain a few
controls for the RTC block hardware (a regulator and RTC block GPIO pin
latches), while also having separate interrupts for the alarms.
The hardware is different enough to make a different driver for it.

This patch exposes the ruleset generation ID in three ways:
1) The new command NFT_MSG_GETGEN that exposes the 32-bits ruleset
generation ID. This ID is incremented in every commit and it
should be large enough to avoid wraparound problems.
2) The less significant 16-bits of the generation ID are exposed through
the nfgenmsg->res_id header field. This allows us to quickly catch
if the ruleset has change between two consecutive list dumps from
different object lists (in this specific case I think the risk of
wraparound is unlikely).
3) Userspace subscribers may receive notifications of new rule-set
generation after every commit. This also provides an alternative
way to monitor the generation ID. If the events are lost, the
userspace process hits a overrun error, so it knows that it is
working with a stale ruleset anyway.
Patrick spotted that rule-set transformations in userspace may take
quite some time. In that case, it annotates the 32-bits generation ID
before fetching the rule-set, then:
1) it compares it to what we obtain after the transformation to
make sure it is not working with a stale rule-set and no wraparound
has ocurred.
2) it subscribes to ruleset notifications, so it can watch for new
generation ID.
This is complementary to the NLM_F_DUMP_INTR approach, which allows
us to detect an interference in the middle one single list dumping.
There is no way to explicitly check that an interference has occurred
between two list dumps from the kernel, since it doesn't know how
many lists the userspace client is actually going to dump.

In order to make the number of interrupts configurable, use the new

It is now quite easy to delay the allocation of the vgic tables
until we actually require it to be up and running (when the first
vcpu is kicking around, or someones tries to access the GIC registers).
This allow us to allocate memory for the exact number of CPUs we
have. As nobody configures the number of interrupts just yet,
use a fallback to VGIC_NR_IRQS_LEGACY.

Now that we can (almost) dynamically size the number of interrupts,
we're facing an interesting issue:
We have to evaluate at runtime whether or not an access hits a valid
register, based on the sizing of this particular instance of the
distributor. Furthermore, the GIC spec says that accessing a reserved
register is RAZ/WI.
For this, add a new field to our range structure, indicating the number
of bits a single interrupts uses. That allows us to find out whether or
not the access is in range.

So far, all the VGIC data structures are statically defined by the
*maximum* number of vcpus and interrupts it supports. It means that
we always have to oversize it to cater for the worse case.
Start by changing the data structures to be dynamically sizeable,
and allocate them at runtime.
The sizes are still very static though.

As it stands, nothing prevents userspace from injecting an interrupt
before the guest's GIC is actually initialized.
This goes unnoticed so far (as everything is pretty much statically
allocated), but ends up exploding in a spectacular way once we switch
to a more dynamic allocation (the GIC data structure isn't there yet).
The fix is to test for the "ready" flag in the VGIC distributor before
trying to inject the interrupt. Note that in order to avoid breaking
userspace, we have to ignore what is essentially an error.

Writes to GICD_ISPENDR0 and GICD_ICPENDR0 ignore all settings of the

correctly.
Signed-off-by: Christoffer Dall <christoffer.dall@linaro.org>

Writes to GICD_ISPENDRn and GICD_ICPENDRn are currently not handled
correctly for level-triggered interrupts. The spec states that for
level-triggered interrupts, writes to the GICD_ISPENDRn activate the
output of a flip-flop which is in turn or'ed with the actual input
interrupt signal. Correspondingly, writes to GICD_ICPENDRn simply
deactivates the output of that flip-flop, but does not (of course) affect
the external input signal. Reads from GICC_IAR will also deactivate the
flip-flop output.
This requires us to track the state of the level-input separately from
the state in the flip-flop. We therefore introduce two new variables on
the distributor struct to track these two states. Astute readers may
notice that this is introducing more state than required (because an OR
of the two states gives you the pending state), but the remaining vgic
code uses the pending bitmap for optimized operations to figure out, at
the end of the day, if an interrupt is pending or not on the distributor
side. Refactoring the code to consider the two state variables all the
places where we currently access the precomputed pending value, did not
look pretty.

If we unqueue a level-triggered interrupt completely, and the LR does
not stick around in the active state (and will therefore no longer
generate a maintenance interrupt), then we should clear the queued flag
so that the vgic can actually queue this level-triggered interrupt at a
later time and deal with its pending state then.
Note: This should actually be properly fixed to handle the active state
on the distributor.

We have a special bitmap on the distributor struct to keep track of when
level-triggered interrupts are queued on the list registers. This was
named irq_active, which is confusing, because the active state of an
interrupt as per the GIC spec is a different thing, not specifically
related to edge-triggered/level-triggered configurations but rather
indicates an interrupt which has been ack'ed but not yet eoi'ed.
Rename the bitmap and the corresponding accessor functions to irq_queued
to clarify what this is actually used for.

The irq_state field on the distributor struct is ambiguous in its
meaning; the comment says it's the level of the input put, but that
doesn't make much sense for edge-triggered interrupts. The code
actually uses this state variable to check if the interrupt is in the
pending state on the distributor so clarify the comment and rename the
actual variable and accessor methods.

Currently, devices for SSP ports 1, 2 and 3 are registered as compatible
devices to pxa27x-ssp. While the actual IP core is comparable, there are
some subtle differences which users of the SSP ports address by looking at
the 'type' field.
By registering devices of type 'pxa27x-ssp', this 'type' field is
incorrectly set to PXA27x_SSP which confuses the users.
To fix this, provide specific ssp port plaform devices which use
'pxa3xx-ssp' as driver name, an instantiate them from pxa3xx.c.
