2012-12-13microblaze: lib: Add lib function declarationsMichal Simek
Function declarations fix these sparse warnings: arch/microblaze/lib/ashldi3.c:5:11: warning: symbol '__ashldi3' was not declared. Should it be static? arch/microblaze/lib/muldi3.c:50:8: warning: symbol '__muldi3' was not declared. Should it be static? arch/microblaze/lib/cmpdi2.c:5:11: warning: symbol '__cmpdi2' was not declared. Should it be static? arch/microblaze/lib/lshrdi3.c:5:11: warning: symbol '__lshrdi3' was not declared. Should it be static? arch/microblaze/lib/ashrdi3.c:5:11: warning: symbol '__ashrdi3' was not declared. Should it be static? arch/microblaze/lib/ucmpdi2.c:5:11: warning: symbol '__ucmpdi2' was not declared. Should it be static? Signed-off-by: Michal Simek <michal.simek@xilinx.com>

2012-03-30microblaze: Fix stack usage in PAGE_SIZE copy_tofrom_userMichal Simek
If access to user space failed we need to reconstruct stack pointer and restore all register. This patch fixed problem introduces by: "microblaze: Add loop unrolling for PAGE in copy_tofrom_user" (sha1: ebe211254bfa6295f4ab0b33c7c881bdfabbab60) 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>

2010-10-21microblaze: 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>

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>
