ea6dedd7fb ARM: OMAP: GPIO IRQ lazy IRQ disable fix
- The current OMAP GPIO IRQ framework doesn't use the do_edge_IRQ,
  do_level_IRQ handlers, but instead calls do_simple_IRQ. This
  doesn't handle disabled interrupts properly, so drivers will
  still get interrupts after calling disable_irq. The patch solves
  this by respecting the irq_desc.disable_depth and irq_desc.running
  counters.  When one of these is non-zero the handler is not called,
  the interrupt is masked and marked as pending. The pending interrupt
  will be serviced when the running handler returns. This is according
  to the same semantics as the standard do_edge_IRQ and do_level_IRQ
  handlers have, so one day we should use them instead of do_simple_IRQ.

- Process only interrupts that are not masked. The ISR may contain
  pending interrupts that are masked these shouldn't be processed.

- Move the bank IRQ unmasking out of the IRQ dispatch loop. If there
  are further iterations we shouldn't unmask it if there are level
  triggered interrupts pending.

Remove VM_LOCKED before remap_pfn range from device drivers and get rid of
VM_SHM.

remap_pfn_range() already sets VM_IO.  There is no need to set VM_SHM since
it does nothing.  VM_LOCKED is of no use since the remap_pfn_range does not
place pages on the LRU.  The pages are therefore never subject to swap
anyways.  Remove all the vm_flags settings before calling remap_pfn_range.

After removing all the vm_flag settings no use of VM_SHM is left.  Drop it.

f606a6ff22 [ARM] 3626/1: ARM EABI: fix syscall restarting
Patch from Nicolas Pitre

The RESTARTBLOCK case currently store some code on the stack to invoke
sys_restart_syscall.  However this is ABI dependent and there is a
mismatch with the way __NR_restart_syscall gets defined when the kernel
is compiled for EABI.

There is also a long standing bug in the thumb case since with OABI the
__NR_restart_syscall value includes __NR_SYSCALL_BASE which should not
be the case for Thumb syscalls.

1a6be26d5b [ARM] Enable VFP to be built when non-VFP capable CPUs are selected
Since we pass flags to the compiler to control code generation based
on the least capable selected CPU, if we want to include VFP support,
we must tweak the assembler flags to allow the VFP instructions.
Moreover, we must not use the mrrc/mcrr versions since these will not
be recognised by the assembler.

We do not convert all instructions to the VFP-equivalent (yet) since
binutils appears to barf on "fmrx rn, fpinst" and doesn't provide any
other way (other than using the mrc equivalent) to encode this
instruction - which is rather a problem when you have a VFP
implementation which requires these instructions.

d6551e884c [ARM] Add thread_notify infrastructure
Some machine classes need to allow VFP support to be built into the
kernel, but still allow the kernel to run even though VFP isn't
present.  Unfortunately, the kernel hard-codes VFP instructions
into the thread switch, which prevents this being run-time selectable.

Solve this by introducing a notifier which things such as VFP can
hook into to be informed of events which affect the VFP subsystem
(eg, creation and destruction of threads, switches between threads.)

Patch from Andrew Victor

This patch adds the core Power Management support for the AT91RM9200
processor.  It will support suspend-to-RAM and standby modes.

The suspend-to-RAM functionality is not 100% complete.  The code that
needs to be execute from the internal SRAM to restore the system is
outstanding.  For now we just fall through to Standby mode.

The AT91-specific at91_suspend_entering_slow_clock() function will
eventually be replaced by clk_must_disable() once that functionality is
added to mainline clock API.

067bbada4c [ARM] 3589/1: AT91RM9200 DK/EK board update
Patch from Andrew Victor

This patch updates the support for the Atmel DK and EK boards.

The changes include:
1. Use the new at91_uart_config structure and device registration
functions for the UARTs.
2. Registration of I2C and SPI platform devices.
3. The USB Device pullup line is connected to reset, so multidrive needs
to be enabled on the line.  [Patch from David Brownell].

Patch from Andrew Victor

This patch updates the platform device support for the AT91RM9200.

The changes include:

1. USB Host device renamed to "at91_ohci" since the driver is also
usable on the AT91SAM9261 processor.
2. Enabling multidrive on the USB Device's pullup pin should not be done
for all boards.  Moved into board-specific files.  [Patch from David
Brownell]
3. Move enabling of PCMCIA/Compact Flash pins out of the driver.
4. Added SPI device and resources.
5. Added Watchdog device and resources.  [Patch from David Brownell]
6. Added UART device and resources.
7. The simple devices (watchdog, rtc, i2c) are now automatically
registered and don't have to be registered separately in each
board-specific file. [Patch from David Brownell]

| We can kill them.  I checked with Phil B. about them last week, and he
| didn't remember any reason they still needed to be there.  And nothing

Patch from Paul Brook

The old-abi sys_syscall syscall is broken when called from Thumb mode. It
assumes the syscall number is an Arm syscall number (ie. starts from
__NR_OABI_SYSCALL_BASE).  In thumb mode syscall numbers start from zero.

The patch below fixes this by clearing the nigh bits of the syscall number
instead of inverting them. Technically this means we accept some invalid
syscall numbers, but I can't see how that could be a problem. The two sets of
numbers far apart that unimplemented syscalls should still be rejected.

Now that kconfig can load multiple configurations, it becomes simple to
integrate the split config step, by simply comparing the new .config file with
the old auto.conf (and then saving the new auto.conf).  A nice side effect is
that this saves a bit of disk space and cache, as no data needs to be read

e2f04e1894 [ARM] 3546/1: PATCH: subtle lost interrupts bug on i.MX
Patch from Matt Reimer

There is a subtle bug in the GPIO interrupt status register
handling in arch/arm/mach-imx/irq.c:imx_gpio_ack_irq(). The
documentation states that a 1 should be written to the relevant bit to
acknowledge a GPIO interrupt, but that is not what the code does.

The problem is that the |= writes back 1s for all the *other*
interrupts represented in the register, so interrupts could get lost.
For example, if interrupts are pending for GPIO B10 and B12, ISR_B
would have the value 0x00001400. Then when the interrupt code handles
GPIO B10, it eventually calls imx_gpio_ack_irq(IRQ_GPIOB(10)), which
effectively does this:

ISR_B |= 1 << 10;

with the result that (0x00001400 | 0x00000400) is written, clearing
the interrupt status bits for *both* GPIO B10 and B12.

The fix is to write 1s only for the interrupts we want to clear.

The same problem seems to be occurring in the DMA code; this patch
does not address those issues.

0c27c5d5b9 [ARM] 3547/1: PXA-OHCI: Allow platforms to specify a power budget
Patch from Richard Purdie

Add a power budget variable to the PXA OHCI platform data and add a
default value for the spitz platform(s) which prevents known failures
with certain USB devices.

d782f33df7 [ARM] Fix Neponset IRQ handling
While testing the genirq code on ARM, a condition was found whereby
the Neponset IRQ handler was being re-entered, causing the system
to deadlock.

Under the ARM IRQ code, this would not have been a visible problem
because the "simple" IRQ handling had no re-entrancy protection.

Resolve this by acknowledging the parent interrupt after we mask it
when we are going to handle one of our "special" level-based sources
(from ethernet or USAR chip.)

a7d14f875f [ARM] 3543/1: [Fwd: PXA270 bootparams address not set]
Patch from Steve Yang

MACHINE_START struct doesn't have any bootargs location for the
mainstone. Result is no kernel command args get passed; no serial driver
is selected for console and results in a silent boot failure.
