Fix end of statement location. Where the last line of the statement is replaced we are miss reporting the newly added replacement an incorrectly indented trailing statement for the negative context. We are also incorrectly reporting negative statements generally. Signed-off-by:

We are incorrectly counting the lines in a block while accumulating the trailing lines in a macro statement, leading to false positives. Fix end of block handling and general counting for negative context lines. Signed-off-by:

Some types such as typedefs may overlap real identifiers. Be more targetted about when a type can really exist. Where it cannot let it be an identifier. This prevents false reporting of the minus '-' in unary context in the following: foo[bar->bool - 1]; Signed-off-by:

Casts require parentheses so it is possible to have something like this: return (int)(*a); This miss trips the complexity function. Ensure that the two separate parenthesised sections are not coelesced. Signed-off-by:

This patch will only setup one clock, if free, and return this clock to the caller. The previous solution would setup both clocks with the same prescaler and divider and return PWM_CPR_CLKB, thus taking both clocks in the same call without the caller knowing. Signed-off-by:

set_type returns an int indicating success or failure, but up to now setup_irq ignores that. In my case this resulted in a machine hang: gpio-keys requested IRQF_TRIGGER_RISING | IRQF_TRIGGER_FALLING, but arm/ns9xxx can only trigger on one direction so set_type didn't touch the configuration which happens do default to a level sensitiveness and returned -EINVAL. setup_irq ignored that and unmasked the irq. This resulted in an endless triggering of the gpio-key interrupt service routine which effectively killed the machine. With this patch applied setup_irq propagates the error to the caller. Note that before in the case chip && !chip->set_type && !chip->name a NULL pointer was feed to printk. This is fixed, too. Signed-off-by:

Trying to compile the v850 port brings many compile errors, one of them exists since at least kernel 2.6.19. There also seems to be noone willing to bring this port back into a usable state. This patch therefore removes the v850 port. If anyone ever decides to revive the v850 port the code will still be available from older kernels, and it wouldn't be impossible for the port to reenter the kernel if it would become actively maintained again.

Fix try_to_freeze_tasks()'s use of do_div() on an s64 by making elapsed_csecs64 a u64 instead and dividing that. Possibly this should be guarded lest the interval calculation turn up negative, but the possible negativity of the result of the division is cast away anyway. This was introduced by patch 438e2ce6.

There are a few BIOSes that we know of already that need to use the ACPI 1.0 suspend order. This appears to be only be a small minority of mostly nVidia based systems. Based on observation of Windows behaviour, it's clear that Windows is also doing maintaining its own list of broken hardware that needs this workaround. Signed-off-by:

ACPI defines a hardware signature. BIOS calculates the signature according to hardware configure and if hardware changes while hibernated, the signature will change. In that case, S4 resume should fail. Still, there may be systems on which this mechanism does not work correctly, so it is better to provide a workaround for them. For this reason, add a new switch to the acpi_sleep= command line argument allowing one to disable hardware signature checking. [shaohua.li@intel.com: build fix] Signed-off-by:

This interface allows adding a job on a specific cpu. Although a work struct on a cpu will be scheduled to other cpu if the cpu dies, there is a recursion if a work task tries to offline the cpu it's running on. we need to schedule the task to a specific cpu in this case. http://bugzilla.kernel.org/show_bug.cgi?id=10897 [oleg@tv-sign.ru: cleanups] Signed-off-by:

This patch simplifies the memory bitmap manipulations. - remove the member size in struct bm_block It is not necessary for struct bm_block to have the number of bit chunks that can be calculated by using end_pfn and start_pfn. - use find_next_bit() for memory_bm_next_pfn No need to invent the bitmap library only for the memory bitmap.

Boot-time test for system suspend states (STR or standby). The generic RTC framework triggers wakeup alarms, which are used to exit those states. - Measures some aspects of suspend time ... this uses "jiffies" until someone converts it to use a timebase that works properly even while timer IRQs are disabled. - Triggered by a command line parameter. By default nothing even vaguely troublesome will happen, but "test_suspend=mem" will give you a brief STR test during system boot. (Or you may need to use "test_suspend=standby" instead, if your hardware needs that.) This isn't without problems. It fires early enough during boot that for example both PCMCIA and MMC stacks have misbehaved. The workaround in those cases was to boot without such media cards inserted.

Andrew G. Morgan authored
To date, we've tried hard to confine filesystem support for capabilities to the security modules. This has left a lot of the code in kernel/capability.c in a state where it looks like it supports something that filesystem support for capabilities actually suppresses when the LSM security/commmoncap.c code runs. What is left is a lot of code that uses sub-optimal locking in the main kernel With this change we refactor the main kernel code and make it explicit which locks are needed and that the only remaining kernel races in this area are associated with non-filesystem capability code.

When cap_bset suppresses some of the forced (fP) capabilities of a file, it is generally only safe to execute the program if it understands how to recognize it doesn't have enough privilege to work correctly. For legacy applications (fE!=0), which have no non-destructive way to determine that they are missing privilege, we fail to execute (EPERM) any executable that requires fP capabilities, but would otherwise get pP' < fP. This is a fail-safe permission check. For some discussion of why it is problematic for (legacy) privileged applications to run with less than the set of capabilities requested for them, see: http://userweb.kernel.org/~morgan/sendmail-capabilities-war-story.html With this iteration of this support, we do not include setuid-0 based privilege protection from the bounding set. That is, the admin can still (ab)use the bounding set to suppress the privileges of a setuid-0 program.
