2011-10-24gpiolib: Ensure struct gpio is always definedMark Brown1-12/+1
Currently struct gpio is only defined when using gpiolib which makes the stub gpio_request_array() much less useful in drivers than is ideal as they can't work with struct gpio. Since there are no other definitions in kernel instead make the define always available no matter if gpiolib is selectable or selected, ensuring that drivers can always use the type.

2011-07-26atomic: cleanup asm-generic atomic*.h inclusionArun Sharma1-2/+0
After changing all consumers of atomics to include <linux/atomic.h>, we ran into some compile time errors due to this dependency chain: linux/atomic.h -> asm/atomic.h -> asm-generic/atomic-long.h where atomic-long.h could use funcs defined later in linux/atomic.h without a prototype. This patches moves the code that includes asm-generic/atomic*.h to linux/atomic.h.

2011-07-22asm-generic: delay.h fix udelay and ndelay for 8 bit argsAndrew Morton1-6/+27
With a non-constant 8-bit argument, a call to udelay() generates a warning: drivers/gpu/drm/radeon/atom.c: In function 'atom_op_delay': drivers/gpu/drm/radeon/atom.c:654: warning: comparison is always false due to limited range of data type The code looks like it works OK with an 8-bit arg, and the calling code is doing nothing wrong, so udelay() needs fixing. Fixing it was rather tricky. Simply typecasting `n' in the comparison with 20000 didn't change anything. Hence the divide-by-20000 trick. Using a do{}while loop didn't work because udelay() is used in ?: statements, hence the ({...}) construct. While I was there I replaced the brain-bending ?:?:?: mess with nice if/else code. Probably other architectures are generating the same warning and can use a similar change.

2011-07-07asm-generic: adapt delay.h to common implementationJonas Bonn1-1/+15
Several architectures are using a common delay.h implementation that appears to have originated with the x86 architecture. This common implementation is a bit fuller than the current asm-generic version and has some compile-time checks that should be interesting for all architectures. This patch takes the common delay.h version and replaces the rather trivial asm-generic version with it. As no architecture was actually using asm-generic/delay.h, this change is rather innocuous; it will, however, allow us to switch at least four architectures over to using the asm-generic version.

2011-05-28ns: Wire up the setns system callEric W. Biederman1-1/+3
32bit and 64bit on x86 are tested and working. The rest I have looked at closely and I can't find any problems. setns is an easy system call to wire up. It just takes two ints so I don't expect any weird architecture porting problems. While doing this I have noticed that we have some architectures that are very slow to get new system calls. cris seems to be the slowest where the last system calls wired up were preadv and pwritev. avr32 is weird in that recvmmsg was wired up but never declared in unistd.h. frv is behind with perf_event_open being the last syscall wired up. On h8300 the last system call wired up was epoll_wait. On m32r the last system call wired up was fallocate. mn10300 has recvmmsg as the last system call wired up. The rest seem to at least have syncfs wired up which was new in the 2.6.39. v2: Most of the architecture support added by Daniel Lezcano <dlezcano@fr.ibm.com> v3: ported to v2.6.36-rc4 by: Eric W. Biederman <ebiederm@xmission.com> v4: Moved wiring up of the system call to another patch v5: ported to v2.6.39-rc6 v6: rebased onto parisc-next and net-next to avoid syscall conflicts. v7: ported to Linus's latest post 2.6.39 tree. >  arch/blackfin/include/asm/unistd.h     |    3 ++- >  arch/blackfin/mach-common/entry.S      |    1 + Acked-by: Mike Frysinger <vapier@gentoo.org> Oh - ia64 wiring looks good.

2011-05-26bitops: add #ifndef for each of find bitopsAkinobu Mita2-0/+11
The style that we normally use in asm-generic is to test the macro itself for existence, so in asm-generic, do: #ifndef find_next_zero_bit_le extern unsigned long find_next_zero_bit_le(const void *addr, unsigned long size, unsigned long offset); #endif and in the architectures, write static inline unsigned long find_next_zero_bit_le(const void *addr, unsigned long size, unsigned long offset) #define find_next_zero_bit_le find_next_zero_bit_le This adds the #ifndef for each of the find bitops in the generic header and source files.

2011-05-26asm-generic/ptrace.h: start a common low level ptrace helperMike Frysinger1-0/+74
This is a series of low level ptrace unification steps to make it easier for common code (like KGDB) to poke at register state. This also avoids having to duplicate higher level operations for most ports which don't have special needs for accessing things. This patch: This implements a bunch of helper funcs for poking the registers of a ptrace structure. Now common code should be able to portably update specific registers (like kgdb updating the PC).

2011-05-26bug.h: Move ratelimit warn interfaces to ratelimit.hDavid S. Miller1-40/+0
As reported by Ingo Molnar, we still have configuration combinations where use of the WARN_RATELIMIT interfaces break the build because dependencies don't get met. Instead of going down the long road of trying to make it so that ratelimit.h can get included by kernel.h or asm-generic/bug.h, just move the interface into ratelimit.h and make users have to include that.

2011-05-25ulimit: raise default hard ulimit on number of files to 4096Tim Gardner1-1/+1
Apps are increasingly using more than 1024 file descriptors. See discussion in several distro bug trackers, e.g. BugLink: http://bugs.launchpad.net/bugs/663090 https://issues.rpath.com/browse/RPL-2054 You don't want to raise the default soft limit, since that might break apps that use select(), but it's safe to raise the default hard limit; that way, apps that know they need lots of file descriptors can raise their soft limit without needing root, and without user intervention. Ubuntu is doing this with a kernel change because they have a policy of not changing kernel defaults in userland. While 4096 might not be enough for *all* apps, it seems to be plenty for the apps I've seen lately that are unhappy with 1024.

2011-05-25asm-generic/cacheflush.h: flush icache when copying to user pagesMike Frysinger1-1/+4
The copy_to_user_page() function is supposed to flush the icache on the memory that was written, but the current asm-generic version lacks that logic. While normally it isn't a big deal as the asm-generic version of icache flushing is a stub, it is a deal for ports that want to use the asm-generic version as a baseline and then overlay its own specific parts (like icache flushing).

2011-05-25mm: mmu_gather reworkPeter Zijlstra1-27/+69
Rework the existing mmu_gather infrastructure. The direct purpose of these patches was to allow preemptible mmu_gather, but even without that I think these patches provide an improvement to the status quo. The first 9 patches rework the mmu_gather infrastructure. For review purpose I've split them into generic and per-arch patches with the last of those a generic cleanup. The next patch provides generic RCU page-table freeing, and the followup is a patch converting s390 to use this. I've also got 4 patches from DaveM lined up (not included in this series) that uses this to implement gup_fast() for sparc64. Then there is one patch that extends the generic mmu_gather batching. After that follow the mm preemptibility patches, these make part of the mm a lot more preemptible. It converts i_mmap_lock and anon_vma->lock to mutexes which together with the mmu_gather rework makes mmu_gather preemptible as well. Making i_mmap_lock a mutex also enables a clean-up of the truncate code. This also allows for preemptible mmu_notifiers, something that XPMEM I think wants. Furthermore, it removes the new and universially detested unmap_mutex. This patch: Remove the first obstacle towards a fully preemptible mmu_gather. The current scheme assumes mmu_gather is always done with preemption disabled and uses per-cpu storage for the page batches. Change this to try and allocate a page for batching and in case of failure, use a small on-stack array to make some progress. Preemptible mmu_gather is desired in general and usable once i_mmap_lock becomes a mutex. Doing it before the mutex conversion saves us from having to rework the code by moving the mmu_gather bits inside the pte_lock. Also avoid flushing the tlb batches from under the pte lock, this is useful even without the i_mmap_lock conversion as it significantly reduces pte lock hold times.
