The driver checks status of PCI power management to mark
default setting of Wake On Lan. On some systems this works, but often
it reports a that WOL is disabled when it isn't.

This patch gets rid of that check and just reports the wake on
lan status based on the hardware capablity.

This patch might fix problems with 4G or more of memory.
It stops the driver from doing a small optimization for Tx and Rx,
and instead always sets the high-page on tx/rx descriptors.

Here's the reworked patch.

This cleans up some unnecessary byte-swapping while setting up tx and
interpreting rx desc. The 64 bit rx status data should be converted
to host endian format only once and the macros just need to extract
bitfields.

This saves a spate of interrupts on pseries blades caused by buggy
(non) processing rx status ring.

netxen driver allows limited number of threads simultaneously posting
skb's in tx ring. If transmit slot is unavailable, driver calls
schedule() or loops in xmit_frame().

This patch returns TX_BUSY and lets the stack reschedule the packet if
transmit slot is unavailable. Also removes unnecessary check for tx
timeout in the driver itself, the network stack does that anyway.

Since the introduction of the acquire_console_sem calls in
0333d835, kexecing can cause the
kernel to deadlock:

 ps3fb_shutdown()
  -> unregister_framebuffer()
  -> fb_notifier_call_chain(FB_EVENT_FB_UNBIND)
  -> fbcon_fb_unbind()
  -> unbind_con_driver()
  -> bind_con_driver()
	[ acquires console_sem ]
  -> fbcon_deinit()
  -> fbops->fb_release(newinfo, 0)
  -> ps3fb_release()
  -> ps3fb_sync()
	[ acquires console_sem ]

This change avoids the deadlock by moving the acquire_console_sem()
out of ps3fb_sync(), and puts it into the two other callsites, leaving
ps3fb_release() to call ps3fb_sync() without the console semaphore.

[Geert]
  - Corrected call sequence above
  - ps3fb_release() may be called with and without console_sem held. This is an
    inconsistency that should be fixed at the fb level, but for now, try to
    acquire console_sem in ps3fb_release().

    I think it's safer to let ps3fb_release() try to acquire console_sem and
    not refresh the screen if it fails, than to call ps3fb_sync() without
    holding console_sem, as ps3fb_par may be modified at the same time, causing
    crashes or lockups.

    Besides, ps3fb_release() only calls ps3fb_sync() to refresh the screen
    when display flipping is disabled, which is an uncommon case (except during
    shutdown/kexec).

The bug causes corruptions of data read from flash.

The original code performs cache invalidation from "adr" to "adr + len"
in do_write_buffer().  Since len and adr could be updated in the code
before invalidation - it causes improper setting of cache invalidation

I noticed that the commit f1974653
(MIPS Tech: Get rid of volatile in core code) broke the software
reset functionality for MIPS Malta boards in big-endian mode.

According to the MIPS Malta board user's manual, writing the magic
32-bit GORESET value into the SOFTRES register initiates board soft
reset. My experimentation has shown that the endianness of the GORESET
integer should thereby be the same as the endianness, which has been
set for the CPU itself. The writew() function used to write the magic
value in the code introduced by the commit mentioned above, however,
swaps bytes for big-endian kernels and transfers 16 bits instead of 32.

The patch below replaces the writew() function by the __raw_writel()
routine, which leaves the byte order intact and transfers the whole
MIPS machine word. Trivial code cleanup (replacing spaces by a tab
and cutting oversized lines to make checkpatch.pl happy) is also
included.

The patch was tested using a Malta evaluation board running in both
BE and LE modes. For both modes, software reset was fully functional
after the change.

P.S. I suspect that the same commit broke the "standby" functionality
for MIPS Atlas boards. However, I did not touch the Atlas code as I
don't have such board at my disposal and also because the linux-mips.org
Web site claims that Atlas support is scheduled for removal.

is cpu_clock() which is not a global time source.

Fix bkltrace timestamps by using ktime_get() like the networking
