| * asm-generic: merge branch 'master' of torvalds/linux-2.6Arnd Bergmann2009-06-12
| |\ | | | | | | | | | | | | | | | | | | Fixes a merge conflict against the x86 tree caused by a fix to atomic.h which I renamed to atomic_long.h. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
| * | asm-generic: rename page.h and uaccess.hArnd Bergmann2009-06-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current asm-generic/page.h only contains the get_order function, and asm-generic/uaccess.h only implements unaligned accesses. This renames the file to getorder.h and uaccess-unaligned.h to make room for new page.h and uaccess.h file that will be usable by all simple (e.g. nommu) architectures.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The existing asm-generic/atomic.h only defines the atomic_long type. This renames it to atomic-long.h so we have a place to add a truly generic atomic.h that can be used on all non-SMP systems.

| * | asm-generic: introduce asm/bitsperlong.hArnd Bergmann2009-06-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This provides a reliable way for asm-generic/types.h and other files to find out if it is running on a 32 or 64 bit platform. We cannot use CONFIG_64BIT for this in headers that are included from user space because CONFIG symbols are not available there. We also cannot do it inside of asm/types.h because some headers need the word size but cannot include types.h. The solution is to introduce a new header <asm/bitsperlong.h> that defines both __BITS_PER_LONG for user space and BITS_PER_LONG for usage in the kernel. The asm-generic version falls back to 32 bit unless the architecture overrides it, which I did for all 64 bit platforms.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The existing asm-generic versions are incomplete and included by some architectures. New architectures should be able to use a generic version, so rename the existing files and change all users, which lets us add the new files.

* flat: fix data sections alignmentOskar Schirmer2009-05-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The flat loader uses an architecture's flat_stack_align() to align the stack but assumes word-alignment is enough for the data sections. However, on the Xtensa S6000 we have registers up to 128bit width which can be used from userspace and therefor need userspace stack and data-section alignment of at least this size. This patch drops flat_stack_align() and uses the same alignment that is required for slab caches, ARCH_SLAB_MINALIGN, or wordsize if it's not defined by the architecture. It also fixes m32r which was obviously kaput, aligning an uninitialized stack entry instead of the stack pointer.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current definition of CALLER_ADDRx isn't suitable for all platforms. E.g. for ARM __builtin_return_address(N) doesn't work for N > 0 and AFAIK for powerpc there are no frame pointers needed to have a working __builtin_return_address. This patch allows defining the CALLER_ADDRx macros in <asm/ftrace.h> and let these take precedence. Because now <asm/ftrace.h> is included unconditionally in <linux/ftrace.h> all archs that don't already had this include get an empty one for free.
