Revision 72dd299d5039a336493993dcc63413cf31d0e662 authored by Dan Williams on 16 January 2015, 23:13:02 UTC, committed by Tejun Heo on 19 January 2015, 14:10:07 UTC
Ronny reports: https://bugzilla.kernel.org/show_bug.cgi?id=87101 "Since commit 8a4aeec8d "libata/ahci: accommodate tag ordered controllers" the access to the harddisk on the first SATA-port is failing on its first access. The access to the harddisk on the second port is working normal. When reverting the above commit, access to both harddisks is working fine again." Maintain tag ordered submission as the default, but allow sata_sil24 to continue with the old behavior.

#! /bin/sh
# Script to apply kernel patches.
# usage: patch-kernel [ sourcedir [ patchdir [ stopversion ] [ -acxx ] ] ]
# The source directory defaults to /usr/src/linux, and the patch
# directory defaults to the current directory.
# e.g.
# scripts/patch-kernel . ..
# Update the kernel tree in the current directory using patches in the
# directory above to the latest Linus kernel
# scripts/patch-kernel . .. -ac
# Get the latest Linux kernel and patch it with the latest ac patch
# scripts/patch-kernel . .. 2.4.9
# Gets standard kernel 2.4.9
# scripts/patch-kernel . .. 2.4.9 -ac
# Gets 2.4.9 with latest ac patches
# scripts/patch-kernel . .. 2.4.9 -ac11
# Gets 2.4.9 with ac patch ac11
# Note: It uses the patches relative to the Linus kernels, not the
# ac to ac relative patches
#
# It determines the current kernel version from the top-level Makefile.
# It then looks for patches for the next sublevel in the patch directory.
# This is applied using "patch -p1 -s" from within the kernel directory.
# A check is then made for "*.rej" files to see if the patch was
# successful. If it is, then all of the "*.orig" files are removed.
#
# Nick Holloway <Nick.Holloway@alfie.demon.co.uk>, 2nd January 1995.
#
# Added support for handling multiple types of compression. What includes
# gzip, bzip, bzip2, zip, compress, and plaintext.
#
# Adam Sulmicki <adam@cfar.umd.edu>, 1st January 1997.
#
# Added ability to stop at a given version number
# Put the full version number (i.e. 2.3.31) as the last parameter
# Dave Gilbert <linux@treblig.org>, 11th December 1999.
# Fixed previous patch so that if we are already at the correct version
# not to patch up.
#
# Added -ac option, use -ac or -ac9 (say) to stop at a particular version
# Dave Gilbert <linux@treblig.org>, 29th September 2001.
#
# Add support for (use of) EXTRAVERSION (to support 2.6.8.x, e.g.);
# update usage message;
# fix some whitespace damage;
# be smarter about stopping when current version is larger than requested;
# Randy Dunlap <rdunlap@xenotime.net>, 2004-AUG-18.
#
# Add better support for (non-incremental) 2.6.x.y patches;
# If an ending version number if not specified, the script automatically
# increments the SUBLEVEL (x in 2.6.x.y) until no more patch files are found;
# however, EXTRAVERSION (y in 2.6.x.y) is never automatically incremented
# but must be specified fully.
#
# patch-kernel does not normally support reverse patching, but does so when
# applying EXTRAVERSION (x.y) patches, so that moving from 2.6.11.y to 2.6.11.z
# is easy and handled by the script (reverse 2.6.11.y and apply 2.6.11.z).
# Randy Dunlap <rdunlap@xenotime.net>, 2005-APR-08.
