* Detach sched.h from mm.hAlexey Dobriyan2007-05-212-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | First thing mm.h does is including sched.h solely for can_do_mlock() inline function which has "current" dereference inside. By dealing with can_do_mlock() mm.h can be detached from sched.h which is good. See below, why. This patch a) removes unconditional inclusion of sched.h from mm.h b) makes can_do_mlock() normal function in mm/mlock.c c) exports can_do_mlock() to not break compilation d) adds sched.h inclusions back to files that were getting it indirectly. e) adds less bloated headers to some files (asm/signal.h, jiffies.h) that were getting them indirectly Net result is: a) mm.h users would get less code to open, read, preprocess, parse, ... if they don't need sched.h b) sched.h stops being dependency for significant number of files: on x86_64 allmodconfig touching sched.h results in recompile of 4083 files, after patch it's only 3744 (-8.3%). Cross-compile tested on all arm defconfigs, all mips defconfigs, all powerpc defconfigs, alpha alpha-up arm i386 i386-up i386-defconfig i386-allnoconfig ia64 ia64-up m68k mips parisc parisc-up powerpc powerpc-up s390 s390-up sparc sparc-up sparc64 sparc64-up um-x86_64 x86_64 x86_64-up x86_64-defconfig x86_64-allnoconfig as well as my two usual configs.

* atomic.h: atomic_add_unless as inline. Remove system.h atomic.h circular ↵Mathieu Desnoyers2007-05-081-16/+31
| | | | | | | | | | | | | | | | | | | | | | | dependency atomic_add_unless as inline. Remove system.h atomic.h circular dependency. I agree (with Andi Kleen) this typeof is not needed and more error prone. All the original atomic.h code that uses cmpxchg (which includes the atomic_add_unless) uses defines instead of inline functions, probably to circumvent a circular dependency between system.h and atomic.h on powerpc (which my patch addresses). Therefore, it makes sense to use inline functions that will provide type checking. atomic_add_unless as inline. Remove system.h atomic.h circular dependency. Digging into the FRV architecture shows me that it is also affected by such a circular dependency. Here is the diff applying this against the rest of my atomic.h patches. It applies over the atomic.h standardization patches.

* Clean up mostly unused IOSPACE macrosDavid Gibson2007-05-081-4/+0
| | | | | | | | | | | | | | | Most architectures defined three macros, MK_IOSPACE_PFN(), GET_IOSPACE() and GET_PFN() in pgtable.h. However, the only callers of any of these macros are in Sparc specific code, either in arch/sparc, arch/sparc64 or drivers/sbus.

* move die notifier handling to common codeChristoph Hellwig2007-05-081-0/+1
| | | | | | | | | | | | | | | | | | | | | | | This patch moves the die notifier handling to common code. Previous various architectures had exactly the same code for it. Note that the new code is compiled unconditionally, this should be understood as an appel to the other architecture maintainer to implement support for it aswell (aka sprinkling a notify_die or two in the proper place) arm had a notifiy_die that did something totally different, I renamed it to arm_notify_die as part of the patch and made it static to the file it's declared and used at. avr32 used to pass slightly less information through this interface and I brought it into line with the other architectures.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add hooks to allow a paravirt implementation to track the lifetime of an mm. Paravirtualization requires three hooks, but only two are needed in common code. They are: arch_dup_mmap, which is called when a new mmap is created at fork arch_exit_mmap, which is called when the last process reference to an mm is dropped, which typically happens on exit and exec. The third hook is activate_mm, which is called from the arch-specific activate_mm() macro/function, and so doesn't need stub versions for other architectures. It's called when an mm is first used.

* [NET]: Adding SO_TIMESTAMPNS / SCM_TIMESTAMPNS supportEric Dumazet2007-04-261-0/+2
| | | | | | | | | | | | | | | | | | | | | Now that network timestamps use ktime_t infrastructure, we can add a new SOL_SOCKET sockopt SO_TIMESTAMPNS. This command is similar to SO_TIMESTAMP, but permits transmission of a 'timespec struct' instead of a 'timeval struct' control message. (nanosecond resolution instead of microsecond) Control message is labelled SCM_TIMESTAMPNS instead of SCM_TIMESTAMP A socket cannot mix SO_TIMESTAMP and SO_TIMESTAMPNS : the two modes are mutually exclusive. sock_recv_timestamp() became too big to be fully inlined so I added a __sock_recv_timestamp() helper function.

There is no obvious reason why these numbers should be architecture specific, nor any apparent relationship with the termios structure. The total number of these, NR_LDISCS, is defined in linux/tty.h anyway. So I propose the following patch which moves the definitions of the individual line disciplines to linux/tty.h too. Three of these numbers (N_MASC, N_PROFIBUS_FDL, and N_SMSBLOCK) are unused in the current kernel, but the patch still keeps the complete set in case there are plans to use them yet.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since get_user_pages() may be used with processes other than the current process and calls flush_anon_page(), flush_anon_page() has to cope in some way with non-current processes. It may not be appropriate, or even desirable to flush a region of virtual memory cache in the current process when that is different to the process that we want the flush to occur for. Therefore, pass the vma into flush_anon_page() so that the architecture can work out whether the 'vmaddr' is for the current process or not. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
