2016-05-05asm-generic: Drop renameat syscall from default listJames Hogan
The newer renameat2 syscall provides all the functionality provided by the renameat syscall and adds flags, so future architectures won't need to include renameat. Therefore drop the renameat syscall from the generic syscall list unless __ARCH_WANT_RENAMEAT is defined by the architecture's unistd.h prior to including asm-generic/unistd.h, and adjust all architectures using the generic syscall list to define it so that no in-tree architectures are affected.

2015-09-09Revert "Hexagon: fix signal.c compile error"Mike Frysinger
This reverts commit f3f601c1d2728f02544cfd143eaa82e5398b3e9b. UAPI headers cannot use "uapi/" in their paths by design -- when they're installed, they do not have the uapi/ prefix. Otherwise doing so breaks userland badly. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Richard Kuo <rkuo@codeaurora.org>
2014-04-04Hexagon: remove SP macroRichard Kuo
The SP/r29 macro wasn't used anywhere else and was causing conflicts with another module, so just remove it. Signed-off-by: Richard Kuo <rkuo@codeaurora.org>
2014-04-04arch: hexagon: include: uapi: asm: setup.h add swith macro __KERNEL__Chen Gang
Define dummy '__init' instead of include "linux/init.h" if !__KERNEL__, or can not pass checking. The related error (with allmodconfig under hexagon): CHECK include/asm (34 files) usr/include/asm/setup.h:22: included file 'linux/init.h' is not exported Signed-off-by: Chen Gang <gang.chen.5i5j@gmail.com> Signed-off-by: Richard Kuo <rkuo@codeaurora.org>

Based on feedback from Al Viro; previous-stack-pointer and user reg for same should always be kept consistent. Signed-off-by: Richard Kuo <rkuo@codeaurora.org>

2013-04-30Hexagon: Signal and return path fixesRichard Kuo
This fixes the return value of sigreturn and moves the work pending check into a c routine for readability and fixes the loop for multiple pending signals. Based on feedback from Al Viro. Signed-off-by: Richard Kuo <rkuo@codeaurora.org>
2013-04-30Hexagon: add support for new v4+ registersRichard Kuo
Add support for a couple new v4+ registers, along with newer save/restore pt_regs. Signed-off-by: Richard Kuo <rkuo@codeaurora.org>
2012-12-19Bury the conditionals from kernel_thread/kernel_execve seriesAl Viro
All architectures have CONFIG_GENERIC_KERNEL_THREAD CONFIG_GENERIC_KERNEL_EXECVE __ARCH_WANT_SYS_EXECVE None of them have __ARCH_WANT_KERNEL_EXECVE and there are only two callers of kernel_execve() (which is a trivial wrapper for do_execve() now) left. Kill the conditionals and make both callers use do_execve(). Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
