pci_dma_sync_single was obsoleted long ago.

All the comments are generic, not architecture specific, simply describes
some of the DMA-API (and the same comments are in other files).
Documentation/DMA-API.txt have more detailed descriptions.

This removes the above obsolete and unnecessary DMA API comments.  Let's
describe the DMA API in only Documentation/DMA-API.txt.

The exact hardware error handling code was added before the workaround
for anomaly 283 which caused the anomaly to be triggered in some cases
(an infinite core stall).  So re-order the code to avoid this.

The on-chip keypad peripheral requires different registers to be setup
depending on the standby type (standby vs hibernation).  However, since
the power management framework doesn't differentiate between these types,
the driver doesn't know which registers to program and subsequently it
avoids doing so.

Always enabling the keyboard wakeup source causes misbehavior when the
pins are not assigned to the keypad.  If they happen to drive a certain
level, they'll trigger a wake up event which is not wanted.  So until
the aforementioned issue can be sorted out, drop support for the
wakeup source completely.

This patch provides infrastructure for MAC Wake-On-Lan and PHYINT use in
phylib.  New Interrupts added:

IRQ_MAC_PHYINT   /* PHY_INT Interrupt */
IRQ_MAC_MMCINT   /* MMC Counter Interrupt */
IRQ_MAC_RXFSINT  /* RX Frame-Status Interrupt */
IRQ_MAC_TXFSINT  /* TX Frame-Status Interrupt */
IRQ_MAC_WAKEDET  /* Wake-Up Interrupt */
IRQ_MAC_RXDMAERR /* RX DMA Direction Error Interrupt */
IRQ_MAC_TXDMAERR /* TX DMA Direction Error Interrupt */
IRQ_MAC_STMDONE  /* Station Mgt. Transfer Done Interrupt */

On BF537/6 the implementation is not straight forward since there are now
two chained chained_handlers.  A cleaner approach would have been to add
latter IRQs to the demux of IRQ_GENERIC_ERROR.

We want to report all system calls (even invalid ones) to the tracing
layers, so check the NR only after we've notified.
Signed-off-by: NMike Frysinger <vapier@gentoo.org>

On Blackfin systems, the hardware single step exception triggers before
the system call exception, so we need to save this info to process it
later on.  Otherwise, single stepping in userspace misses a few insns
right after the system call.

This is based a bit on the SuperH code added in commit 4b505db9.

We don't want to let user space modify the SYSCFG register arbitrarily as
the settings are system wide (SNEN/CNEN) and can cause misbehavior.  The
only other bit here (SSSTEP) has proper controls via PTRACE_SINGLESTEP.

Use the generic ptrace_resume code for PTRACE_SYSCALL, PTRACE_CONT,
PTRACE_KILL and PTRACE_SINGLESTEP.  This implies defining
arch_has_single_step in <asm/ptrace.h> and implementing the
user_enable_single_step and user_disable_single_step functions, which
also causes the breakpoint information to be cleared on fork, which
could be considered a bug fix.

Also the TIF_SYSCALL_TRACE thread flag is now cleared on PTRACE_KILL
which it previously wasn't which is consistent with all architectures
using the modern ptrace code.

This functions are implicitly called by core functions like cpu_relax(),
and since those functions may be called early on before common code has
initialized the per-cpu data area, we need to tweak the stats gathering.
Now the statistics are maintained in common bss which makes these funcs
safe to use as soon as the C runtime env is setup.
