When DEBUG_LL is not set, we don't want __error_a re-entering
__lookup_machine_type - we want it to go to the error function. This
used to be the case before we reorganized the layout for hotplug cpu,
as we used to fall through to __error. With the changed layout, we
need an explicit branch here instead.

Drive strength for PXA910 is a 2 bit value but because of the mapping in
plat-pxa/mfp.h needs to be shifted up one bit to handle real
location in mfp registers. (MMP2 and PXA910 drive strength start
at bit 11 while PXA168 starts at bit 10).
Values 0, 1, 2, and 3 effectively need to be
0, 2, 4, and 6 to fit into register. 8 does not work.

Rabin Vincent reports:
| On SMP, this BUG() in save_stack_trace_tsk() can be easily triggered
| from user space by reading /proc/$PID/stack, where $PID is any pid but
| the current process:
|
| if (tsk != current) {
| #ifdef CONFIG_SMP
| /*
| * What guarantees do we have here that 'tsk'
| * is not running on another CPU?
| */
| BUG();
| #else
Fix this by replacing the BUG() with an entry to terminate the stack
trace, returning an empty trace - I'd rather not expose the dwarf
unwinder to a volatile stack of a running thread.

There is no need for syscall_exit_fields as the syscall
exit event class can already host the fields in its structure,
like most other trace events do by default. Use that
default behavior instead.
Following this scheme, we don't need anymore to override the
get_fields() callback of the syscall exit event class either.
Hence both syscall_exit_fields and syscall_get_exit_fields() can
be removed.
Also changed some indentation to keep the following under 80
characters:
".fields = LIST_HEAD_INIT(event_class_syscall_exit.fields),"

Do not use memory bank info to request the "system ram" resources as
they do not track holes created by memblock_remove inside
machine's reserve callback. If the removed memory is passed as
platform_device's ioresource, then drivers that call
request_mem_region would fail due to a conflict with the incorrectly
configured system ram resource.
Instead, iterate through the regions of memblock.memory and add
those as "System RAM" resources.

It's indicative of a real problem, and it actually triggers with
autofs4, but the BUG_ON() is excessive. The autofs4 case is being fixed
(to only set d_op in the ->lookup method) but not merged yet. In the

Fixes the following:
1. POLL should not enable IRQ when work is not completed
2. No locking between TX descriptor cleaning and XMIT descriptor handling
3. No locking between RX POLL and XMIT modifying control register
4. Since TX cleaning (called from POLL) is running in parallel with XMIT
unnecessary locking is needed.
5. IRQ handler looks at RX frame status solely, this is wrong when IRQ is
temporarily disabled (in POLL), and when IRQ is shared.
6. IRQ handler clears IRQ status, which is unnecessary
7. TX queue was stopped in preventing cause when not MAX_SKB_FRAGS+1
descriptors were available after a SKB been scheduled by XMIT. Instead
the TX queue is stopped first when not enough descriptors are available
upon entering XMIT.
It was hard to split up this patch in smaller pieces since all are tied
together somehow.
Note the RX flag used in the interrupt handler does not signal that
interrupt was asserted, but that a frame was received. Same goes for TX.
Also, IRQ is not asserted when the RX flag is set before enabling IRQ
enable until a new frame is received. So extra care must be taken to
avoid enabling IRQ and all descriptors are already used, hence dead lock
will upon us. See new POLL implementation that enableds IRQ then look at
the RX flag to determine if one or more IRQs may have been missed. TX/RX
flags are cleared before handling previously enabled descriptors, this
ensures that the RX/TX flags are valid when determining if IRQ should be
turned on again.
By moving TX cleaning from POLL to XMIT in the standard case, removes some
locking trouble. Enabling TX cleaning from poll only when not enough TX
descriptors are available is safe because the TX queue is at the same time
stopped, thus XMIT will not be called. The TX queue is woken up again when
enough descriptrs are available.
TX Frames are always enabled with IRQ, however the TX IRQ Enable flag will
not be enabled until XMIT must wait for free descriptors.
Locking RX and XMIT parts of the driver from each other is needed because
the RX/TX enable bits share the same register.
