arch/avr32/kernel/cpu.c needs THIS_MODULE, so it must include
linux/module.h.Signed-off-by: Haavard Skinnemoen

Two libgcc headers were left around even though all the actual code
borrowed from libgcc is gone. Delete them.Signed-off-by: Haavard Skinnemoen
-
Move stuff in spi.c into ATSTK1002 board code and update SPI
platform device definitions according to the new GPIO API.Signed-off-by: Haavard Skinnemoen
-
The PIOE device was left out before because it muxes SDRAM pins (and
is therefore a bit dangerous to mess with) and because no existing
drivers had any use for it.It is needed for CompactFlash, however, and now that we have a way
to protect the SDRAM pins, it can be safely added.Signed-off-by: Haavard Skinnemoen
-
at32_reserve_pin() can be used for reserving portmux pins without
altering their configuration. Useful for e.g. SDRAM pins where we
really don't want to change the bootloader-provided configuration.Signed-off-by: Haavard Skinnemoen
-
Leave the PIO lines as the bootloader left them. This allows us to
use PIOE without disturbing the SDRAM muxing.Signed-off-by: Haavard Skinnemoen

Fix bug in dma_map_single(..., DMA_FROM_DEVICE) caused by incorrect
invalidation of shared cachelines at the beginning and/or end of
the specified buffer. Those shared cachelines need to be flushed,
since they may hold valid data (which must not be discarded).Signed-off-by: David Brownell

Bugfixes for external irq handler set_irq_type():
- If set_irq_type() can't set the type, don't change anything!
- It's not OK to change the flow handler as part of set_irq_type(),
among other issues that violates spinlock rules. Instead, we can
call the relevant handler when we demux the external interrupts.- The external irq demux has no need to grab the spinlock. And in
fact grabbing it that way was wrong, since that code might be
pre-empted by an irq at a different priority level, and that code
might then have tried to grab that spinlock...Signed-off-by: David Brownell

Fixes to USART setup on the stk-1000 ... don't configure USART 2, since
its TXD/RXD are used for INT-A and INT-B buttons; and configure USART 0

The following macro :
include/asm-powerpc/vga.h:#define VGA_MAP_MEM(x,s) (x + vgacon_remap_base)
is used by drivers/video/console/vgacon.c which can be compiled as a module
(drivers/video/vga16fb.ko).Therefore, vgacon_remap_base should be exported.

The previous patch changing pSeries to use H_BULK_REMOVE broke the
JS20 blade, where the firmware doesn't support H_BULK_REMOVE. This
adds a firmware check so that on machines that don't have H_BULK_REMOVE,
we just use the H_REMOVE call as before.Signed-off-by: Paul Mackerras

The arch hooks arch_setup_msi_irq and arch_teardown_msi_irq are now
responsible for allocating and freeing the linux irq in addition to
setting up the the linux irq to work with the interrupt.arch_setup_msi_irq now takes a pci_device and a msi_desc and returns
an irq.With this change in place this code should be useable by all platforms
except those that won't let the OS touch the hardware like ppc RTAS.Signed-off-by: Eric W. Biederman

We need to be able to get from an irq number to a struct msi_desc.
The msi_desc array in msi.c had several short comings the big one was
that it could not be used outside of msi.c. Using irq_data in struct
irq_desc almost worked except on some architectures irq_data needs to
be used for something else.So this patch adds a msi_desc pointer to irq_desc, adds the appropriate
wrappers and changes all of the msi code to use them.The dynamic_irq_init/cleanup code was tweaked to ensure the new
field is left in a well defined state.Signed-off-by: Eric W. Biederman

When we do full FP emulation its possible that we need to post a SIGFPE based
on the results of the emulation. The previous code ignored this case completely.Additionally, the Soft_emulate_8xx case had two issues. One, we should never
generate a SIGFPE since the code only does data movement. Second, we were
interpreting the return codes incorrectly, it returns 0 on success, 1 on
illop and -EFAULT on a data access error.Signed-off-by: Kumar Gala

Anytime we are emulating an instruction we are going to be doing some form of
get_user() to get the instruction image to decode. Since get_user() might
sleep we need to ensure we have interrupts enabled or we might see something
like:Debug: sleeping function called from invalid context at arch/powerpc/kernel/traps.c:697
