2010-08-13NOMMU: Remove an extraneous no_printk()David Howells1-5/+0
Remove an extraneous no_printk() in mm/nommu.c that got missed when the function got generalised from several things that used it in commit 12fdff3fc248 ("Add a dummy printk function for the maintenance of unused printks"). Without this, the following error is observed: mm/nommu.c:41: error: conflicting types for 'no_printk' include/linux/kernel.h:314: error: previous definition of 'no_printk' was here Reported-by: Michal Simek <monstr@monstr.eu> Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

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.

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.

2010-08-12mm: 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.

2010-08-12x86/hpet: Use the FSEC_PER_SEC constant for femto-second periodsChris Wilson2-3/+3
The current computation, introduced with f12a15be63, of FSEC_PER_SEC using the multiplication of (FSEC_PER_NSEC * NSEC_PER_SEC) is performed only with 32bit integers on small machines, resulting in an overflow and a *very* short intervals being programmed. An interrupt storm follows. Note that we also have to specify FSEC_PER_SEC as being long long to overcome the same limitations.

2010-08-12timekeeping: Fix overflow in rawtime tv_nsec on 32 bit archsJason Wessel1-4/+7
The tv_nsec is a long and when added to the shifted interval it can wrap and become negative which later causes looping problems in the getrawmonotonic(). The edge case occurs when the system has slept for a short period of time of ~2 seconds. A trace printk of the values in this patch illustrate the problem: ftrace time stamp: log 43.716079: logarithmic_accumulation: raw: 3d0913 tv_nsec d687faa 43.718513: logarithmic_accumulation: raw: 3d0913 tv_nsec da588bd 43.722161: logarithmic_accumulation: raw: 3d0913 tv_nsec de291d0 46.349925: logarithmic_accumulation: raw: 7a122600 tv_nsec e1f9ae3 46.349930: logarithmic_accumulation: raw: 1e848980 tv_nsec 8831c0e3 The kernel starts looping at 46.349925 in the getrawmonotonic() due to the negative value from adding the raw value to tv_nsec. A simple solution is to accumulate into a u64, and then normalize it to a timespec_t.

2010-08-12MN10300: Don't try and #include <linux/slab.h> in lib/inflate.c from bootloaderDavid Howells2-0/+3
Don't try and #include <linux/slab.h> in lib/inflate.c from the bootloader code as linux/slab.h hauls in function defs that aren't available in the bootloader code and may also haul in conflicting functions. To fix this, make the inclusion of linux/slab.h contingent on NO_INFLATE_MALLOC as are the usages of kmalloc() and kfree(). In MN10300, this causes the following errors: In file included from include/linux/string.h:21, from include/linux/bitmap.h:8, from include/linux/nodemask.h:93, from include/linux/mmzone.h:16, from include/linux/gfp.h:4, from include/linux/slab.h:12, from arch/mn10300/boot/compressed/../../../../lib/inflate.c:106, from arch/mn10300/boot/compressed/misc.c:170: /warthog/am33/linux-2.6-mn10300/arch/mn10300/include/asm/string.h:19: error: conflicting types for 'memset' arch/mn10300/boot/compressed/misc.c:59: error: previous definition of 'memset' was here Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
