2014-10-02spi: dw-mid: convert to use DMAengine wrappersAndy Shevchenko

2014-10-02spi: dw-mid: change magic numbers to the constantsAndy Shevchenko
Instead of using magic numbers in the code we create a bit map definition of the DMACR register and use it. There is no functional change. Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2014-10-02aarch64: filter $x from kallsymsKyle McMartin
Similar to ARM, AArch64 is generating $x and $d syms... which isn't terribly helpful when looking at %pF output and the like. Filter those out in kallsyms, modpost and when looking at module symbols. Seems simplest since none of these check EM_ARM anyway, to just add it to the strchr used, rather than trying to make things overly complicated. initcall_debug improves: dmesg_before.txt: initcall $x+0x0/0x154 [sg] returned 0 after 26331 usecs dmesg_after.txt: initcall init_sg+0x0/0x154 [sg] returned 0 after 15461 usecs Signed-off-by: Kyle McMartin <kyle@redhat.com> Acked-by: Rusty Russell <rusty@rustcorp.com.au> Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>

2014-10-02ARM: hisi: depend on ARCH_MULTI_V7Arnd Bergmann
hisi has a general dependency on ARCH_MULTIPLATFORM, which is problematic when building a kernel for non-V7 platforms but selecting drivers that might conflict with other architecture levels. In this case, it broke my (still out of tree) patch set that enables V7M multiplatform support, since that does not enable MULTI_IRQ support: arch/arm/kernel/built-in.o: In function `set_handle_irq': arch/arm/kernel/irq.c:125: undefined reference to `handle_arch_irq' arch/arm/kernel/built-in.o: In function `setup_arch': arch/arm/kernel/setup.c:965: undefined reference to `handle_arch_irq' Since all hisilicon platforms are ARMv7 based, we can avoid this problem by just making the dependency more specific.

The parent_transid parameter has been unused since its introduction in ca7a79ad8dbe2466 ("Pass down the expected generation number when reading tree blocks"). In reada_tree_block, it was even wrongly set to leafsize. Transid check is done in the proper read and readahead ignores errors. Signed-off-by: David Sterba <dsterba@suse.cz>
2014-10-02tile gxio: use better string copy primitiveChris Metcalf
Both strncpy and strlcpy suffer from the fact that they do partial copies of strings into the destination when the target buffer is too small. This is frequently pointless since an overflow of the target buffer may make the result invalid. strncpy() makes it relatively hard to even detect the error condition, and with strlcpy() you have to duplicate the buffer size parameter to test to see if the result exceeds it. By returning zero in the failure case, we both make testing for it easy, and by simply not copying anything in that case, we make it mandatory for callers to test the error code. To catch lazy programmers who don't check, we also place a NUL at the start of the destination buffer (if there is space) to ensure that the result is an invalid string. At some point it may make sense to promote strscpy() to a global platform-independent function, but other than the reviewers, no one was interested on LKML, so for now leave the strscpy() function as file-static.
