* | microblaze: clean up checksum.cArnd Bergmann2009-05-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* | microblaze: remove bad_user_access_lengthArnd Bergmann2009-05-21
| | | | | | | | | | | | | | | | This function was actually causing harm, by hiding errors about invalid sized get_user/put_user accesses. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Michal Simek <monstr@monstr.eu>
* | microblaze: do not include types.h in ptrace.hArnd Bergmann2009-05-21
| | | | | | | | | | | | | | | | linux/types.h breaks the uclibc build, so don't include it here. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Michal Simek <monstr@monstr.eu>
* | microblaze: add a dummy pgprot_noncachedArnd Bergmann2009-05-21
| | | | | | | | | | | | | | | | | | | | Some device drivers call this, so add a macro that pretends to do this. Since there is no MMU support, it won't actually result in an uncached mapping, though. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Michal Simek <monstr@monstr.eu>
* | microblaze: add security initcallsArnd Bergmann2009-05-21
| | | | | | | | | | | | | | | | The security subsystem has its own initcalls, which need support in vmlinux.lds.S. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Michal Simek <monstr@monstr.eu>
* | microblaze: remove cacheable_memcpyArnd Bergmann2009-05-21
| | | | | | | | | | | | | | | | 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>
* | microblaze: kill incorrect __bad_xchg definitionArnd Bergmann2009-05-21
| | | | | | | | | | | | | | | | | | | | | | The whole point of the __bad_xchg declaration in system.h is to give a linker error when a variable of invalid size is passed to __xchg. The out of line definition in traps.c defeats this purpose and does not any value, so remove it here. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Michal Simek <monstr@monstr.eu>
* | microblaze: fix __user annotationsArnd Bergmann2009-05-21
| | | | | | | | | | | | | | | | | | | | | | | | The microblaze signal handling code gets some __user pointers wrong, as shown by sparse. This adds the annotations where appropriate and change sys_rt_sigreturn to correctly pass a user stack down to do_sigaltstack instead of a kernel structure.

* | microblaze: export some symbolsArnd Bergmann2009-05-21
| | | | | | | | | | | | | | | | Some device drivers require the symbols _ebss, kernel_thread, __page_offset or ___range_ok, so export them. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Michal Simek <monstr@monstr.eu>

* | of: make of_(un)register_platform_driver common codeGrant Likely2009-05-02
|/ | | | | | | | | | | | | | | | | | | | | | Some drivers using of_register_platform_driver() wrapper break on sparc because the wrapper isn't in the header file. This patch moves it from Microblaze and PowerPC implementations and makes it common code.
