* x86, ia64, smp: use workqueues unconditionally during do_boot_cpu()Suresh Siddha2010-08-102-15/+8
| | | | | | | | | | | | | | | Workqueues are now initialized as part of the early_initcall(). So they are available for use during cold boot process aswell.

| | | | | | | | | | | | PROC_MM doesn't exist in Kconfig. Looking around it looks like a left-over from 2.6.0 or even 2.4 times, last mentioned in a fedora patch for 2.6.10.

| | | | | | | | | | | | | | | | | | | | | This implements hardware performance events for the EV67 and later CPUs within the Linux performance events subsystem. Only using the performance monitoring unit in HP/Compaq's so called "Aggregrate mode" is supported.

Pretty cool -- discovered that the glibc exp2() library routine uses on average 985 cycles to execute 777 CPU instructions whereas Compaq's CPML library version of exp2() uses on average 32 cycles to execute 47 CPU instructions to achieve the same thing!

* kmap_atomic: make kunmap_atomic() harder to misuseCesar Eduardo Barros2010-08-1013-19/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | kunmap_atomic() is currently at level -4 on Rusty's "Hard To Misuse" list[1] ("Follow common convention and you'll get it wrong"), except in some architectures when CONFIG_DEBUG_HIGHMEM is set[2][3]. kunmap() takes a pointer to a struct page; kunmap_atomic(), however, takes takes a pointer to within the page itself. This seems to once in a while trip people up (the convention they are following is the one from kunmap()). Make it much harder to misuse, by moving it to level 9 on Rusty's list[4] ("The compiler/linker won't let you get it wrong"). This is done by refusing to build if the type of its first argument is a pointer to a struct page. The real kunmap_atomic() is renamed to kunmap_atomic_notypecheck() (which is what you would call in case for some strange reason calling it with a pointer to a struct page is not incorrect in your code). The previous version of this patch was compile tested on x86-64. [1] http://ozlabs.org/~rusty/index.cgi/tech/2008-04-01.html [2] In these cases, it is at level 5, "Do it right or it will always break at runtime." [3] At least mips and powerpc look very similar, and sparc also seems to share a common ancestor with both; there seems to be quite some degree of copy-and-paste coding here. The include/asm/highmem.h file for these three archs mention x86 CPUs at its top. [4] http://ozlabs.org/~rusty/index.cgi/tech/2008-03-30.html [5] As an aside, could someone tell me why mn10300 uses unsigned long as the first parameter of kunmap_atomic() instead of void *?

* mm: provide init_mm mm_context initializerHeiko Carstens2010-08-102-4/+5
| | | | | | | | | | | | | | | | | | | Provide an INIT_MM_CONTEXT intializer macro which can be used to statically initialize mm_struct:mm_context of init_mm. This way we can get rid of code which will do the initialization at run time (on s390). In addition the current code can be found at a place where it is not expected. So let's have a common initializer which architectures can use if needed. This is based on a patch from Suzuki Poulose.

Rather than trying to tease apart precisely which things changed due to which type of code review, this commit includes various cleanups in the code: - sparse: Add declarations in headers for globals. - sparse: Fix __user annotations. - sparse: Using gfp_t consistently instead of int. - sparse: removing functions not actually used. - checkpatch: Clean up printk() warnings by using pr_info(), etc.; also avoid partial-line printks except in bootup code. - checkpatch: Use exposed structs rather than typedefs. - checkpatch: Change some C99 comments to C89 comments. In addition, a couple of minor other changes are rolled in to this commit: - Add support for a "raise" instruction to cause SIGFPE, etc., to be raised. - Remove some compat code that is unnecessary when we fully eliminate some of the deprecated syscalls from the generic syscall ABI. - Update the tile_defconfig to reflect current config contents.

Subrectangles of the chip can be allocated by a "create" ioctl on /dev/hardwall, and then to access the UDN in that rectangle, tasks must perform an "activate" ioctl on that same file object after affinitizing themselves to a single cpu in the region. Sending a wormhole-routed message that tries to leave that subrectangle causes all activated tasks to receive a SIGILL (just as they would if they tried to access the UDN without first activating themselves to a hardwall rectangle). The original submission of this code to LKML had the driver instantiated under /proc/tile/hardwall. Now we just use a character device for this, conventionally /dev/hardwall. Some futures planning for the TILE-Gx chip suggests that we may want to have other types of devices that share the general model of "bind a task to a cpu, then 'activate' a file descriptor on a pseudo-device that gives access to some hardware resource". As such, we are using a device rather than, for example, a syscall, to set up and activate this code. As part of this change, the compat_ptr() declaration was fixed and used to pass the compat_ioctl argument to the normal ioctl. So far we limit compat code to 2GB, so the difference between zero-extend and sign-extend (the latter being correct, eventually) had been overlooked.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | CRISv10 uses a pretty old ld, which does not allow ALIGN(0), (It becomes . = 0;) so instead we align to 1 byte. Signed-off-by: Jesper Nilsson <jesper.nilsson@axis.com>
