In order to slowly transition pxa to dmaengine, the legacy code will now
rely on dmaengine to request a channel.
This implies that PXA architecture selects DMADEVICES and MMP_PDMA,
which is not pretty. Yet it enables PXA drivers to be ported one by one,
with part of them using dmaengine, and the
This is the best I could think of to smoothly transition the PXA drivers to
dmaengine, driver by driver. The goal is to :
- be able to port several drivers, but not _all_ of them at the same time
- have both dmaengine and legacy dma code working in the same kernel
- have dma chanels correctly
In order to achieve smooth transition of pxa drivers from old legacy dma
handling to new dmaengine, introduce a function to "hide" dma physical
channels from dmaengine.
This is temporary situation where pxa dma will be handled in 2 places :
- arch/arm/plat-pxa/dma.c
- drivers/dma/mmp_pdma.c
This option crashes the kernel whenever corruption is initially detected. This
is useful when trying to use crash dump analysis to determine where memory was
initially corrupted.
To enable this option use slub_debug=C.

The commit "ARM: pxa: arbitrarily set first interrupt number" changed
the first pxa interrupt to 16.
As a consequence, device-tree builds got broken, because :

- IRQ_BIT(x) calculates the interrupts as : x - PXA_IRQ(0)

Well the idea was to standardize how we check for a kthreads, as opposed
to improving readability or such. Just a suggestion.
Thanks.

Currently, readlink() and follow_link() for the symbolic links in
/proc//fd/* will return -EACCES in the case where looking up the
task finds that it does not exist.
This patch inlines the logic from proc_fd_access_allowed() into these
two functions such that they will return -ESRCH if the lookup

Currently, /proc//map_files/ is restricted to CAP_SYS_ADMIN, and
is only exposed if CONFIG_CHECKPOINT_RESTORE is set. This interface is
very useful for enumerating the files mapped into a process when the
more verbose information in /proc//maps is not needed. It also
allows access to file

Freezing and thawing are separate system calls, task which is supposed

The issue is that the stack for processes is not properly randomized on 64 bit
architectures due to an integer overflow.
The affected function is randomize_stack_top() in file "fs/binfmt_elf.c":
static unsigned long randomize_stack_top(unsigned long stack_top)
