* 'for-linus2' of git://git.profusion.mobi/users/lucas/linux-2.6: Fix common misspellings
2011-04-01microblaze: Fix ftraceMichal Simek
- Do not trace idle loop which takes a lot time - Fix cache handling in generic ftrace code - Do not trace lib functions ashldi3, ashrdi3, lshrdi3 Functions are called from generic ftrace code which can't be traced Signed-off-by: Michal Simek <monstr@monstr.eu>
2011-03-31Fix common misspellingsLucas De Marchi
Fixes generated by 'codespell' and manually reviewed. Signed-off-by: Lucas De Marchi <lucas.demarchi@profusion.mobi>
2011-03-09microblaze: Add missing export symbols for lib functionsMichal Simek
Adding missing export symbols for loadable modules. Signed-off-by: Michal Simek <monstr@monstr.eu>
2011-01-28microblaze: Fix ASM optimized code for LEMichal Simek
Microblaze little-endian doesn't support ASM optimized library functions(memcpy/memmove). Kconfig doens't contain any information about endian that's why it is necessary to check it in the source code. The code is used with barrel shifter is used. Signed-off-by: Michal Simek <monstr@monstr.eu>
2011-01-03microblaze: Fix __muldi3 function for little-endian.Michal Simek
__muldi3 was written for big endian platforms. Code contained half word read/write instructions which are not compatible with little endian cpu. Asm __muldi3 implementation is replaced by C version. Signed-off-by: Michal Simek <monstr@monstr.eu>
2010-11-15arch/microblaze: Remove unnecessary semicolonsJoe Perches
Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Michal Simek <monstr@monstr.eu>
2010-10-21microblaze: Support C optimized lib functions for little-endianMichal Simek
Optimized C library functions can rapidly speedup the kernel. memset doesn't need to be optimized because there is no difference in behavior on little/big endian cpu. Signed-off-by: Michal Simek <monstr@monstr.eu>
2010-10-21microblaze: Separate library optimized functionsMichal Simek
memcpy/memmove/memset Signed-off-by: Michal Simek <monstr@monstr.eu>
2010-10-21microblaze: Add libgcc function directly to kernelMichal Simek
Replaced libgcc functions with asm optimized implementation. Signed-off-by: Michal Simek <monstr@monstr.eu>
2010-04-01microblaze: Support word copying in copy_tofrom_userMichal Simek
Word copying is used only for aligned addresses. Here is space for improving to use any better copying technique. Look at memcpy implementation. Signed-off-by: Michal Simek <monstr@monstr.eu>
2010-04-01microblaze: Adding likely macrosMichal Simek
On the base on GCOV analytics is helpful to add likely/unlikely macros. Signed-off-by: Michal Simek <monstr@monstr.eu>
2010-04-01microblaze: Add .type and .size to ASM functionsMichal Simek
Cachegrind analysis need this fix to be able to log asm functions. Signed-off-by: Michal Simek <monstr@monstr.eu>

2009-12-14microblaze: Simple __copy_tofrom_user for noMMUJohn Williams
This is first patch which clear part of uaccess.h. uaccess.h will be clear later. Signed-off-by: John Williams <john.williams@petalogix.com> Signed-off-by: Michal Simek <monstr@monstr.eu>

2009-07-06microblaze: use the generic lib/checksum.cRemis Lima Baima
The microblaze checksum code is mostly identical to the asm-generic+lib version, so use that instead. Signed-off-by: Remis Lima Baima <remis.developer@googlemail.com> Signed-off-by: Michal Simek <monstr@monstr.eu>

Signed-off-by: Michal Simek <monstr@monstr.eu>
2009-05-21microblaze: clean up checksum.cArnd Bergmann
This changes the function prototypes in the checksum code to have the usual prototypes, typically by turning int arguments into __wsum. Also change csum_partial_copy_from_user() to operate on the right address space and export ip_fast_csum, which is used in modular networking code. The new version is now sparse-clean including endianess checks. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Michal Simek <monstr@monstr.eu>
2009-05-21microblaze: remove cacheable_memcpyArnd Bergmann
This function is neither declared nor used anywhere outside of ppc32, so remove it from microblaze. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Michal Simek <monstr@monstr.eu>
