2010-08-13time: Workaround gcc loop optimization that causes 64bit div errorsJohn Stultz1-3/+4
Early 4.3 versions of gcc apparently aggressively optimize the raw time accumulation loop, replacing it with a divide. On 32bit systems, this causes the following link errors: undefined reference to `__umoddi3' undefined reference to `__udivdi3' The gcc issue has been fixed in 4.4 and greater. This patch replaces the accumulation loop with a do_div, as suggested by Linus.

2010-08-13x86: don't send SIGBUS for kernel page faultsLinus Torvalds1-1/+3
It's wrong for several reasons, but the most direct one is that the fault may be for the stack accesses to set up a previous SIGBUS. When we have a kernel exception, the kernel exception handler does all the fixups, not some user-level signal handler. Even apart from the nested SIGBUS issue, it's also wrong to give out kernel fault addresses in the signal handler info block, or to send a SIGBUS when a system call already returns EFAULT.

2010-08-13mm: keep a guard page below a grow-down stack segmentLinus Torvalds1-0/+23
This is a rather minimally invasive patch to solve the problem of the user stack growing into a memory mapped area below it. Whenever we fill the first page of the stack segment, expand the segment down by one page. Now, admittedly some odd application might _want_ the stack to grow down into the preceding memory mapping, and so we may at some point need to make this a process tunable (some people might also want to have more than a single page of guarding), but let's try the minimal approach first. Tested with trivial application that maps a single page just below the stack, and then starts recursing. Without this, we will get a SIGSEGV _after_ the stack has smashed the mapping. With this patch, we'll get a nice SIGBUS just as the stack touches the page just above the mapping.

2010-08-13Call acpi_video_register() in intel_opregion_init() failure pathDavid Woodhouse1-0/+1
If i915 opregion is present, the acpi_video driver doesn't register itself immediately; it defers that until the i915 opregion code is done. But if that *fails*, the acpi_video driver was never getting registered. And thus I have no backlight support on my Lenovo IdeaPad S10-3. Call acpi_video_register() on the failure path, and it works again.

2010-08-13ctcm: rename READ/WRITE defines to avoid redefinitionsUrsula Braun5-110/+118
READ/WRITE seems to be a bit too generic for defines in a device driver. Just rename them to CTCM_READ/CTCM_WRITE to avoid warnings. Signed-off-by: Ursula Braun <ursula.braun@de.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
