2009-05-21Microblaze: Remove unused variable from paging initMichal Simek
Signed-off-by: Michal Simek <monstr@monstr.eu>
2009-05-21microblaze: Cleanup compiled-in rootfs in BSS sectionMichal Simek
This patch is based on patch from Steve Magnani. There were bug for compiled-in rootfs. We have to move moving rootfs which is in BSS section to _ebss section which is at the end of kernel and then clear bss section not vice-versa. Signed-off-by: Michal Simek <monstr@monstr.eu>
2009-05-21microblaze: Fix early cmdline for CMDLINE_FORCEMichal Simek
This patch fixed parsing early parameters because current implementation does that early parse DTS command line and then parse CMDLINE line which is compiled-in. For case that DTS doesn't contain command line is copied command line from kernel with is done in prom.c that's why I can remove it from machine_early_init. Signed-off-by: Michal Simek <monstr@monstr.eu>
2009-05-21microblaze: Guard __HAVE_ARCH macros with __KERNEL__ in string.hSteve Magnani
A polarity reversal in the __KERNEL__ guard prevents the __HAVE_ARCH flags from being defined in kernel compilation. I noticed that there's now an option for assembly-optimized versions of memcpy and memmove. I believe this may be buggy; when I turn it on, all my printk output gets smashed together, as if the newlines aren't getting copied. Signed-off-by: Steven J. Magnani <steve@digidescorp.com> Signed-off-by: Michal Simek <monstr@monstr.eu>
2009-05-21microblaze: clean LDFLAGS to build kernelThomas Chou
Extra LDFLAGS from user space building may cause kernel failed to compile. Signed-off-by: Thomas Chou <thomas@wytron.com.tw> Signed-off-by: Michal Simek <monstr@monstr.eu>
2009-05-21microblaze: Fix paging init-zone initializationSteve Magnani
This patch fix problem with bad zone initialization. This bug wasn't perform because Microblaze doesn't define CONFIG_ZONE_DMA and ZONE_NORMAL was 0 for this case that's why free_area_init works with correct values. Original message: I believe that the switch from ZONE_DMA (== 0) to ZONE_NORMAL broke the free area initialization. Signed-off-by: Steven J. Magnani <steve@digidescorp.com> Signed-off-by: Michal Simek <monstr@monstr.eu>
2009-05-21microblaze: use generic dma-mapping-broken.hArnd Bergmann
Microblaze does not support the Linux DMA mapping API at this point, so disable CONFIG_NO_DMA. This lets us use the generic dma-mapping-broken.h implementation instead of providing a different copy. Any drivers that try to use DMA mapping now get omitted from Kconfig or produce a link error, rather than failing silently at run time.

2009-05-21microblaze: prepare signal handling for generic unistd.hMichal Simek
We need to define set_restore_sigmask() in order to get pselect and ppoll. Also, the setup_frame function can not be used when __NR_sigreturn is not defined. Signed-off-by: Arnd Bergmann <arnd@arndb.de> 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 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>

2009-05-20MIPS: 64-bit: Fix system lockup.Greg Ungerer
The address range size calculation inside local_flush_tlb_kernel_range() is being truncated by a too small size variable holder on 64-bit systems. The truncated size can result in an erroneous tlbsize check that means we sit spinning inside a loop trying to flush a hige number of TLB entries. This is for all intents and purposes a system hang. Fix by using an appropriately sized valiable to hold the size. [Ralf: Greg's original patch submission identified the issue and fixed one instance in tlb-r4k.c but there there were several more. For consistency I also modified tlb-r3k.c even though that file is only used on 32-bit.] Signed-off-by: Greg Ungerer <gerg@snapgear.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2009-05-20MIPS: IP22: Fix hang in power button interrupt handlerRalf Baechle
The hang was caused by the use of disable_irq() from the interrupt handler itself. Fixed by the use of disable_irq_nosync().
