2014-07-253w-xxxx: fix mis-aligned struct accessesArnd Bergmann
Building an allmodconfig ARM kernel, I get multiple such warnings because of a spinlock contained in packed structure in the 3w-xxxx driver: ../drivers/scsi/3w-xxxx.c: In function 'tw_chrdev_ioctl': ../drivers/scsi/3w-xxxx.c:1001:68: warning: mis-aligned access used for structure member [-fstrict-volatile-bitfields] timeout = wait_event_timeout(tw_dev->ioctl_wqueue, tw_dev->chrdev_request_id == TW_IOCTL_CHRDEV_FREE, timeout); ^ ../drivers/scsi/3w-xxxx.c:1001:68: note: when a volatile object spans multiple type-sized locations, the compiler must choose between using a single mis-aligned access to preserve the volatility, or using multiple aligned accesses to avoid runtime faults; this code may fail at runtime if the hardware does not allow this access The same bug apparently was present in 3w-sas and 3w-9xxx, but has been fixed in the past. This patch uses the same fix by moving the pragma in front of the TW_Device_Extension definition, so it only covers hardware structures.

2010-04-11[SCSI] 3w-xxxx, 3w-9xxx: force 60 second timeoutadam radford
This small patch forces 60 second timeouts for the older 3w-xxxx & 3w-9xxx drivers for systems that don't contain the udev rule for setting scsi timeouts to 60 seconds. Signed-off-by: Adam Radford <aradford@gmail.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>

2005-11-09[PATCH] changing CONFIG_LOCALVERSION rebuilds too much, for no good reasonOlaf Hering
This patch removes almost all inclusions of linux/version.h. The 3 #defines are unused in most of the touched files. A few drivers use the simple KERNEL_VERSION(a,b,c) macro, which is unfortunatly in linux/version.h. There are also lots of #ifdef for long obsolete kernels, this was not touched. In a few places, the linux/version.h include was move to where the LINUX_VERSION_CODE was used. quilt vi `find * -type f -name "*.[ch]"|xargs grep -El '(UTS_RELEASE|LINUX_VERSION_CODE|KERNEL_VERSION|linux/version.h)'|grep -Ev '(/(boot|coda|drm)/|~$)'` search pattern: /UTS_RELEASE\|LINUX_VERSION_CODE\|KERNEL_VERSION\|linux\/\(utsname\|version\).h Signed-off-by: Olaf Hering <olh@suse.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
