The protocol field in ethernet headers is big-endian and should be
annotated as such. This patch allows detection of missing ntohs() calls
on the ethernet protocol field when sparse is run with __CHECK_ENDIAN__
defined.
This is a revised version that includes <linux/types.h> so that the
userspace programs are not confused by __be16. Thanks to David S.
Miller.

Here is the patch that introduces the generic skb_checksum_complete
which also checks for hardware RX checksum faults. If that happens,
it'll call netdev_rx_csum_fault which currently prints out a stack
trace with the device name. In future it can turn off RX checksum.
I've converted every spot under net/ that does RX checksum checks to
use skb_checksum_complete or __skb_checksum_complete with the
exceptions of:
* Those places where checksums are done bit by bit. These will call
netdev_rx_csum_fault directly.
* The following have not been completely checked/converted:
ipmr
ip_vs
netfilter
dccp
This patch is based on patches and suggestions from Stephen Hemminger
and David S. Miller.

I have to revert the recent addition of -imacros to the Makefile to get my
tool chain to build. Without the change, below, I get:
Note that this looks entirely like a toolchain bug. Here is the offending command:
[pid 12163] execve("/usr/lib/gcc-lib/i386-redhat-linux/3.2.2/tradcpp0", ["/usr/lib/gcc-lib/i386-redhat-linux/3.2.2/tradcpp0", "-lang-asm", "-nostdinc", "-Iinclude", "-Iinclude/asm-i386/mach-default", "-D__GNUC__=3", "-D__GNUC_MINOR__=2", "-D__GNUC_PATCHLEVEL__=2", "-D__GXX_ABI_VERSION=102", "-D__ELF__", "-Dunix", "-D__gnu_linux__", "-Dlinux", "-D__ELF__", "-D__unix__", "-D__gnu_linux__", "-D__linux__", "-D__unix", "-D__linux", "-Asystem=posix", "-D__NO_INLINE__", "-D__STDC_HOSTED__=1", "-Acpu=i386", "-Amachine=i386", "-Di386", "-D__i386", "-D__i386__", "-D__tune_i386__", "-D__KERNEL__", "-D__ASSEMBLY__", "-isystem", "/usr/lib/gcc-lib/i386-redhat-linux/3.2.2/include", "-imacros", "include/linux/autoconf.h", "-MD", "arch/i386/kernel/.entry.o.d", "arch/i386/kernel/entry.S", "-o", "/tmp/ccOlsFJR.s"]
Which should execute properly, I think. But it does not:
zach-dev:linux-2.6.14-zach-work $ make
CHK include/linux/version.h
CHK include/linux/compile.h
CHK usr/initramfs_list
AS arch/i386/kernel/entry.o

make: *** [arch/i386/kernel] Error 2
gcc (GCC) 3.2.2 20030222 (Red Hat Linux 3.2.2-5)
Deprecating the -imacros fixes the build for me. It does not appear to be a
simple argument overflow problem in trapcpp0, since deprecating all the defines
reproduces the problem as well. Also, switching -imacros to -include fixes the
problem.

The previous umad deadlock fix left ib_umad_kill_port() still
vulnerable to deadlocking. This patch fixes that by downgrading our
lock to a read lock when we might end up trying to reacquire the lock
for reading.

Move the computation of QP capabilities (max scatter/gather entries,
max inline data, etc) into the kernel, and have the uverbs module
return the values as part of the create QP response. This keeps
precise knowledge of device limits in the low-level kernel driver.
This requires an ABI bump, so while we're making changes, get rid of
the max_sge parameter for the modify SRQ command -- it's not used and
shouldn't be there.

Change the struct ib_device.resize_cq() method to take a plain integer
that holds the new CQ size, rather than a pointer to an integer that
it uses to return the new size. This makes the interface match the
exported ib_resize_cq() signature, and allows the low-level driver to
update the CQ size with proper locking if necessary.
No in-tree drivers are exporting this method yet.

ib_unregister_mad_agent() completes all pending MAD sends and waits
for the agent's send_handler routine to return. umad's send_handler()
calls queue_packet(), which does down_read() on the port mutex to look
up the agent ID. This means that the port mutex cannot be held for
writing while calling ib_unregister_mad_agent(), or else it will
deadlock. This patch fixes all the calls to ib_unregister_mad_agent()
in the umad module to avoid this deadlock.

Add ibX_path files to debugfs that contain information about the IPoIB
path cache. IPoIB ARP only gives GIDs, which the IPoIB driver must
resolve to real IB paths through the ib_sa module. For debugging,
when the ARP table looks OK but traffic isn't flowing, it's useful to
be able to see if the resolution from GID to path worked.
Also clean up the formatting of the existing _mcg debugfs files.

Patch from Liam Girdwood
This patch allows users of the pxa SSP driver to register their own irq
handlers instead of using the default SSP handler. It also cleans up the
CKEN clock and irq detection as the values are now stored in a table.
This patch replaces 2845/1
Changes:-
o Added flags parameter to ssp_init()
o Added SSP_NO_IRQ flag to disable registering of ssp irq handler (for
drivers that want to register their own handler)
o Cleaned up clock and irq detection, values are now stored in table.
o Added build changes to allow other drivers (e.g audio) to select the
ssp driver.
o corgi_ssp.c changed to use new interface.

Patch from Richard Purdie
This patch adds a power and battery management core driver which with
the addition of the right device files, supports the c7x0 and cxx00
series of Sharp Zaurus handhelds.
The driver is complex for several reasons. Battery charging is manually
monitored and controlled. When suspended, the device needs to
periodically partially resume, check the charging status and then
re-suspend. It does without bothering the higher linux layers as
a full resume and re-suspend is unnecessary. The code is carefully
written to avoid interrupts or calling code outside the module under
these circumstances. It also vets the various wake up sources and
monitors the device's power situation.
Hooks to limit the backlight intensity and to notify the battery
monitoring code of backlight events are connected/added as the
backlight is one of the biggest users of power on the device.

Omap24xx support was originally added for 2.6.9 by TI.

omap developers, such as Paul Mundt, Juha Yrjola, Imre Deak,
Tony Lindgren, Richard Woodruff, Nishant Menon, Komal Shah

Patch from Alessandro Zummo
This patch adds support for the LinkSys NSLU2 running with
both big and little-endian kernels. The LinkSys NSLU2 is
a cost engineered ARM, XScale 420 based system similar to
the the Intel IXDP425 evaluation board. It uses the
IXP4XX ARCH.
While this patch applies independently of other patches
the resultant kernel requires further patches to successfully
use onboard devices, including the onboard flash. Since these
patches are independent of this one they will be submitted
separately.
A defconfig is not included here because not all of
the required drivers are actually in the kernel.
We intend to provide one as soon as the patches
will be incorporated in mainstream.
This patch is the combined work of nslu2-linux.org
