2009-05-21microblaze: remove bad_user_access_lengthArnd Bergmann
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>
2009-05-21microblaze: do not include types.h in ptrace.hArnd Bergmann
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>
2009-05-21microblaze: add a dummy pgprot_noncachedArnd Bergmann
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>
2009-05-21microblaze: add security initcallsArnd Bergmann
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>
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>
2009-05-21microblaze: kill incorrect __bad_xchg definitionArnd Bergmann
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>
2009-05-21microblaze: fix __user annotationsArnd Bergmann
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. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Michal Simek <monstr@monstr.eu>
2009-05-21microblaze: export some symbolsArnd Bergmann
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>

2009-05-02of: make of_(un)register_platform_driver common codeGrant Likely
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. Fixes this sparc64 allmodconfig build error (at least): drivers/leds/leds-gpio.c: In function `gpio_led_init': drivers/leds/leds-gpio.c:295: error: implicit declaration of function `of_register_platform_driver' drivers/leds/leds-gpio.c: In function `gpio_led_exit': drivers/leds/leds-gpio.c:311: error: implicit declaration of function `of_unregister_platform_driver' Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: David S.

2009-05-01microblaze: Storage class should be before const qualifierTobias Klauser
The C99 specification states in section 6.11.5: The placement of a storage-class specifier other than at the beginning of the declaration specifiers in a declaration is an obsolescent feature. Signed-off-by: Tobias Klauser <tklauser@distanz.ch> Signed-off-by: Michal Simek <monstr@monstr.eu>
2009-04-23microblaze: add parameter to microblaze_read()Coly Li
