* header cleaning: don't include smp_lock.h when not usedRandy Dunlap2007-05-081-1/+0
| | | | | | | | | | | | Remove includes of <linux/smp_lock.h> where it is not used/needed. Suggested by Al Viro. Builds cleanly on x86_64, i386, alpha, ia64, powerpc, sparc, sparc64, and arm (all 59 defconfigs).

* [PATCH] mark struct file_operations const 6Arjan van de Ven2007-02-121-1/+1
| | | | | | | | | | | Many struct file_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources.

We had similar problems with other ioctls where userspace did things like that. What we did there was to put the compat handler to generic code. The patch below does that, adding a big comment about what's going on and removing the COMPAT_IOCTL entires for these on powerpc that not only weren't ever useful but are duplicated now aswell.

* [PATCH] mostek bogus sparse annotations fixedAl Viro2005-04-241-3/+3
| | | | | | | | | | void * __iomem foo is not a pointer to iomem - it's an iomem variable containing void *. A pile of such guys in arch/sparc64/kernel/time.c, drivers/sbus/char/rtc.c and include/asm-sparc64/mostek.h turned into intended void __iomem *.

* [SPARC]: Provide generic ioctls in Sparc RTC driver.David S. Miller2005-04-211-4/+99
| | | | | | | | | | | | | | | | | | | | Provide support for drivers/char/rtc.c ioctls in the Mostek rtc driver as well as the Sparc specific RTCGET and RTCSET. This allows userspace to be much less messy. Currently util-linux and other spots jump through hoops trying various ioctl variants until it hits the right one whatever driver actually being used supports. Eventually all of this should move over to the genrtc.c driver, but not today... While we are here, fix up the register types for sparse. Thanks to Frans Pop for helping point out this issue.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-161-0/+178
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!
