Russell King [Mon, 14 Jan 2008 22:30:10 +0000]
[NET] smc91x: Make smc91x use IRQ resource trigger flags

smc91x is shared between many different platforms.  Each platform needs
to specify the interrupt type, and in some cases the irq type depends
on more than just the build configuration - it depends on runtime
checks.

Rather than throwing this code into the SMC_IRQ_FLAGS definition, provide
a way for these flags to be passed via the IRQ resource itself.

Note that IRQF_TRIGGER_* constants are intentionally defined to correspond
with the IORESOURCE_IRQ_* interrupt type flags, in much the same way that
the low bits of PCI iomem resources correspond with the BAR flag bits.

Also provide a way to configure smc91x to read the IRQ flags from the
resource.  Once all platforms have been converted over (signified
by all definitions of SMC_IRQ_FLAGS being -1) SMC_IRQ_FLAGS should
be removed.

Russell King [Wed, 23 Jan 2008 12:34:16 +0000]
[ARM] pxa: fix PXA27x resume

When PXA27x wakes up, tick_resume_oneshot() tries to set a timer
interrupt to occur immediately.  Since PXA27x requires at least
MIN_OSCR_DELTA, this causes us to flag an error.

tick_program_event() then increments the next event time by
min_delta_ns.  However, by the time we get back to programming
the next event, the OSCR has incremented such that we fail again.
We repeatedly retry, but the OSCR is too fast for us - we never
catch up, so we never break out of the loop - resulting in us
never apparantly resuming.

Fix this by doubling min_delta_ns.

Russell King [Wed, 23 Jan 2008 12:33:31 +0000]
[ARM] pxa: Avoid fiddling with CKEN register on suspend

The PXA manuals indicate that when in standby or sleep modes, clocks to
peripherals are shut off by the processor itself.  Eg:

PXA270 standby: "In standby mode, all clocks are disabled except those
 for the power manager and the RTC."

PXA270 sleep: "In sleep mode, all clocks are disabled to the processor
 and to all peripherals except the RTC."

PXA255 sleep: "In Sleep Mode, all processor and peripheral clocks are
 disabled, except the RTC."

Therefore, it should be safe to leave the clock enable register alone
prior to entering low power modes for these SoCs.

[ARM] pxa: Add PXA3 standby code hooked into the IRQ wake scheme

Wakeup sources on PXA3 are enabled at two levels.  First, the MFP
configuration has to be set to enable which edges a specific pin
will trigger a wakeup.  The pin also has to be routed to a functional
unit.  Lastly, the functional unit must be enabled as a wakeup source
in the appropriate AD*ER registers (AD2D0ER for standby resume.)

This doesn't fit well with the IRQ wake scheme - we currently do a
best effort conversion from IRQ numbers to functional unit wake enable
bits.  For instance, there's several USB client related enable bits but
there's no corresponding IRQs to determine which you'd want.  Conversely,
there's a single enable bit covering several functional units.

eric miao [Thu, 3 Jan 2008 03:25:56 +0000]
[ARM] pxa: make MFP configuration processor independent

There are two reasons for making the MFP configuration to be processor
independent, i.e. removing the relationship of configuration bits with
actual MFPR register settings:

   1. power management sometimes requires the MFP to be configured
      differently when in run mode or in low power mode

   2. for future integration of pxa{25x,27x} GPIO configurations

The modifications include:

1. introducing of processor independent MFP configuration bits, as
   defined in [include/asm-arm/arch-pxa/mfp.h]:

bit  0.. 9 - MFP Pin Number (1024 Pins Maximum)
bit 10..12 - Alternate Function Selection
bit 13..15 - Drive Strength
bit 16..18 - Low Power Mode State
bit 19..20 - Low Power Mode Edge Detection
bit 21..22 - Run Mode Pull State
and so on,

2. moving the processor dependent code from mfp.h into mfp-pxa3xx.h

3. cleaning up of the MFPR bit definitions

4. mapping of processor independent MFP configuration into processor
   specific MFPR register settings is now totally encapsulated within
   pxa3xx_mfp_config()

5. using of "unsigned long" instead of invented type of "mfp_cfg_t"
   according to Documentation/CodingStyle Chapter 5, usage of this
   in platform code will be slowly removed in later patches

[ARM] 4711/1: pxa: mmc: move DMA specific code to platform layer

This patch is to move pxamci DMA specific code to corresponding
platform layer because using DRCMRRXMMC/DRCMRTXMMC in pxamci.c makes
the driver code dedicated to platform which is not extensible.

[ARM] 4709/1: pxa: mmc: add 26MHz support for pxa3[0|1]0 mmc controller

pxa3[0|1]0 mmc controller can support 26MHz clock mode, they support
SD spec 1.1 and MMC spec 4.0 which specify high speed mode. So host

pxa3[0|1]0.

This patch is to add 26MHz support for them. pxa host clock will be
set to 26MHz mode when the card supported max clock rate is higher
than or equal to 26MHz.

Tao Ma [Thu, 10 Jan 2008 07:20:55 +0000]
ocfs2/dlm: Clear joining_node on hearbeat node down

Currently the process of dlm join contains 2 steps: query join and assert join.
After query join, the joined node will set its joining_node. So if the joining
node happens to panic before the 2nd step, the joined node will fail to clear
its joining_node flag because that node isn't in the domain map. It at least
cause 2 problems.
1. All the new join request will fail. So no new node can mount the volume.
2. The joined node can't umount the volume since during the umount process it
   has to wait for the joining_node to be unknown. So the umount will be hanged.

[PATCH 1/2] ocfs2: add flock lock type

This adds a new dlmglue lock type which is intended to back flock()
requests.

Since these locks are driven from userspace, usage rules are much more
liberal than the typical Ocfs2 internal cluster lock. As a result, we can't
make use of most dlmglue features - lock caching and lock level
optimizations in particular. Additionally, userspace is free to deadlock
itself, so we have to deal with that in the same way as the rest of the
kernel - by allowing a signal to abort a lock request.

In order to keep ocfs2_cluster_lock() complexity down, ocfs2_file_lock()
does it's own dlm coordination. We still use the same helper functions
though, so duplicated code is kept to a minimum.

Local alloc is a performance optimization in ocfs2 in which a node

[PATCH 2/2] ocfs2: Implement group add for online resize

This patch adds the ability for a userspace program to request that a
properly formatted cluster group be added to the main allocation bitmap for
an Ocfs2 file system. The request is made via an ioctl, OCFS2_IOC_GROUP_ADD.
On a high level, this is similar to ext3, but we use a different ioctl as
the structure which has to be passed through is different.

During an online resize, tunefs.ocfs2 will format any new cluster groups
which must be added to complete the resize, and call OCFS2_IOC_GROUP_ADD on
each one. Kernel verifies that the core cluster group information is valid
and then does the work of linking it into the global allocation bitmap.

ocfs2: Initalize bitmap_cpg of ocfs2_super to be the maximum.

This value is initialized from global_bitmap->id2.i_chain.cl_cpg. If there
is only 1 group, it will be equal to the total clusters in the volume. So
as for online resize, it should change for all the nodes in the cluster.
It isn't easy and there is no corresponding lock for it.

bitmap_cpg is only used in 2 areas:
1. Check whether the suballoc is too large for us to allocate from the global
   bitmap, so it is little used. And now the suballoc size is 2048, it rarely
   meet this situation and the check is almost useless.
2. Calculate which group a cluster belongs to. We use it during truncate to
   figure out which cluster group an extent belongs too. But we should be OK
   if we increase it though as the cluster group calculated shouldn't change
   and we only ever have a small bitmap_cpg on file systems with a single
