If the registration of the second I2C channel fails, we really want to
unregister the first one before we return with an error.
While we're here, fix the printk right above so that it displays the
real driver name.

When RPCSEC/GSS and krb5i is used, requests are padded, typically to a multiple
of 8 bytes. This can make the request look slightly longer than it
really is.
As of
f34b95689d2ce001c "The NFSv2/NFSv3 server does not handle zero
length WRITE request correctly",
the xdr decode routines for NFSv2 and NFSv3 reject requests that aren't
the right length, so krb5i (for example) WRITE requests can get lost.
This patch relaxes the appropriate test and enhances the related comment.

task_ppid_nr_ns is called in three places. One of these should never
have called it. In the other two, using it broke the existing
semantics. This was presumably accidental. If the function had not
been there, it would have been much more obvious to the eye that those
patches were changing the behavior. We don't need this function.
In task_state, the pid of the ptracer is not the ppid of the ptracer.
In do_task_stat, ppid is the tgid of the real_parent, not its pid.
I also moved the call outside of lock_task_sighand, since it doesn't
need it.
In sys_getppid, ppid is the tgid of the real_parent, not its pid.

pnpacpi: exceeded the max number of IO resources: 40
While this message is a real error and should thus
remain KERN_ERR (even a new dmesg line is seen as a regression
by some, since it was not printed in 2.6.23...) it is certainly
impolite to print this warning 50 times should you happen to
have the oddball system with 90 io resources under a device...
So print the warning just once.
In 2.6.25 we'll get rid of the limits altogether
and these warnings will vanish with them.

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,

Way back when (in commit 834f2a4a1554dc5b2598038b3fe8703defcbe467, aka
"VFS: Allow the filesystem to return a full file pointer on open intent"
to be exact), Trond changed the open logic to keep track of the original
flags to a file open, in order to pass down the the intent of a dentry
lookup to the low-level filesystem.
However, when doing that reorganization, it changed the meaning of
namei_flags, and thus inadvertently changed the test of access mode for
directories (and RO filesystem) to use the wrong flag. So fix those
test back to use access mode ("acc_mode") rather than the open flag
("flag").

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
0333d83509c7d8496c8965b5ba9bc0c98e83c259, 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
regions.

ACPI and APM used "pm_active" to guarantee that
they would not be simultaneously active.
But pm_active was recently moved under CONFIG_PM_LEGACY,
so that without CONFIG_PM_LEGACY, pm_active became a NOP --
allowing ACPI and APM to both be simultaneously enabled.
This caused unpredictable results, including boot hangs.
Further, the code under CONFIG_PM_LEGACY is scheduled
for removal.
So replace pm_active with pm_flags.
pm_flags depends only on CONFIG_PM,
which is present for both CONFIG_APM and CONFIG_ACPI.
