+ * Authors: Patrick McHardy, <kaber@trash.net>
+ *
+ * The first version was written by Martin Devera, <devik@cdi.cz>
+ *
+ * Credits: Jan Rafaj <imq2t@cedric.vabo.cz>
+ * - Update patch to 2.4.21
+ * Sebastian Strollo <sstrollo@nortelnetworks.com>
+ * - Fix "Dead-loop on netdevice imq"-issue
+ * Marcel Sebek <sebek64@post.cz>
+ * - Update to 2.6.2-rc1
+ *
+ * After some time of inactivity there is a group taking care
+ * of IMQ again: http://www.linuximq.net
+ *
+ *
+ * 2004/06/30 - New version of IMQ patch to kernels <=2.6.7 including
+ * the following changes:
+ *
+ * - Correction of ipv6 support "+"s issue (Hasso Tepper)
+ * - Correction of imq_init_devs() issue that resulted in
+ * kernel OOPS unloading IMQ as module (Norbert Buchmuller)
+ * - Addition of functionality to choose number of IMQ devices
+ * during kernel config (Andre Correa)
+ * - Addition of functionality to choose how IMQ hooks on
+ * PRE and POSTROUTING (after or before NAT) (Andre Correa)
+ * - Cosmetic corrections (Norbert Buchmuller) (Andre Correa)
+ *
+ *
+ * 2005/12/16 - IMQ versions between 2.6.7 and 2.6.13 were
+ * released with almost no problems. 2.6.14-x was released
+ * with some important changes: nfcache was removed; After
+ * some weeks of trouble we figured out that some IMQ fields
+ * in skb were missing in skbuff.c - skb_clone and copy_skb_header.
+ * These functions are correctly patched by this new patch version.
+ *
+ * Thanks for all who helped to figure out all the problems with
+ * 2.6.14.x: Patrick McHardy, Rune Kock, VeNoMouS, Max CtRiX,
+ * Kevin Shanahan, Richard Lucassen, Valery Dachev (hopefully
+ * I didn't forget anybody). I apologize again for my lack of time.

X-Git-Tag: v2.6.24-rc1~1273^2~3
X-Git-Url: http://git.kernel.org/?p=linux%2Fkernel%2Fgit%2Ftorvalds%2Flinux-2.6.git;a=commitdiff_plain;h=1e621a8e3752367d4aae78a8ab00a18fb2793f34;hp=033b8ffe3f1ea8174d51d125838ac6deea60f63f
[ARM] 4600/1: fix kernel build failure with build-id-supporting binutils
Newer versions of binutils support --build-id, which adds an ELF
note section called ".note.gnu.build-id" to the output. On the ARM
kernel build, because there is no explicit mention of this section
in the shipped ld script, this section is placed at vaddr 0x00000000
(whereas the normal kernel text/data typically starts at vaddr
0xc0008000), causing the output of objcopy (Image) to produce a 3G+
file.
This patch makes objcopy strip the .note.gnu.build-id section from
the Image file along with all other note sections, which fixes the
build.

I/O memory accessors. Big endian version. For those busses/devices
that do export big-endian I/O memory.

Paulus,
A similar patch for ppc64 made it upstream with your big ppc64 merge.
This one is still sitting in http://patchwork.ozlabs.org/linuxppc/
and didn't make it with the ppc32 equivalent. Thanks.
