sparc32: fix sparse warnings in sys_sparc_32.c

2014-05-19T02:01:28+00:00

Fix following warnings: sys_sparc_32.c:32:26: warning: symbol 'sys_getpagesize' was not declared. Should it be static? sys_sparc_32.c:71:16: warning: symbol 'sparc_pipe' was not declared. Should it be static? sys_sparc_32.c:96:26: warning: symbol 'sys_mmap2' was not declared. Should it be static? sys_sparc_32.c:106:26: warning: symbol 'sys_mmap' was not declared. Should it be static? sys_sparc_32.c:114:6: warning: symbol 'sparc_remap_file_pages' was not declared. Should it be static? sys_sparc_32.c:127:1: warning: symbol 'c_sys_nis_syscall' was not declared. Should it be static? sys_sparc_32.c:144:1: warning: symbol 'sparc_breakpoint' was not declared. Should it be static? sys_sparc_32.c:200:16: warning: symbol 'sys_getdomainname' was not declared. Should it be static? Adapt systbls.h for use by both sparc32 + sparc64. In the process modify the return type of a few functions. Change return type from unsigned long to long: sys_mmap2() sys_mmap() Change return type from int to long: sparc_pipe() sys_getdomainname() The changed return type was done to align with sparc64.

sparc: switch to use of generic old sigaction

2013-02-04T03:43:35+00:00

note that due to historical accident we do *not* directly take generic versions - need to check and invert the sign of signal number first. Signed-off-by: Al Viro

sanitize rt_sigaction() situation a bit

2013-02-03T20:09:18+00:00

Switch from __ARCH_WANT_SYS_RT_SIGACTION to opposite (!CONFIG_ODD_RT_SIGACTION); the only two architectures that need it are alpha and sparc. The reason for use of CONFIG_... instead of __ARCH_... is that it's needed only kernel-side and doing it that way avoids a mess with include order on many architectures. Signed-off-by: Al Viro

Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/signal

2012-12-12T20:22:13+00:00

Pull big execve/kernel_thread/fork unification series from Al Viro: "All architectures are converted to new model. Quite a bit of that stuff is actually shared with architecture trees; in such cases it's literally shared branch pulled by both, not a cherry-pick. A lot of ugliness and black magic is gone (-3KLoC total in this one): - kernel_thread()/kernel_execve()/sys_execve() redesign. We don't do syscalls from kernel anymore for either kernel_thread() or kernel_execve(): kernel_thread() is essentially clone(2) with callback run before we return to userland, the callbacks either never return or do successful do_execve() before returning. kernel_execve() is a wrapper for do_execve() - it doesn't need to do transition to user mode anymore. As a result kernel_thread() and kernel_execve() are arch-independent now - they live in kernel/fork.c and fs/exec.c resp. sys_execve() is also in fs/exec.c and it's completely architecture-independent. - daemonize() is gone, along with its parts in fs/*.c - struct pt_regs * is no longer passed to do_fork/copy_process/ copy_thread/do_execve/search_binary_handler/->load_binary/do_coredump. - sys_fork()/sys_vfork()/sys_clone() unified; some architectures still need wrappers (ones with callee-saved registers not saved in pt_regs on syscall entry), but the main part of those suckers is in kernel/fork.c now." * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/signal: (113 commits) do_coredump(): get rid of pt_regs argument print_fatal_signal(): get rid of pt_regs argument ptrace_signal(): get rid of unused arguments get rid of ptrace_signal_deliver() arguments new helper: signal_pt_regs() unify default ptrace_signal_deliver flagday: kill pt_regs argument of do_fork() death to idle_regs() don't pass regs to copy_process() flagday: don't pass regs to copy_thread() bfin: switch to generic vfork, get rid of pointless wrappers xtensa: switch to generic clone() openrisc: switch to use of generic fork and clone unicore32: switch to generic clone(2) score: switch to generic fork/vfork/clone c6x: sanitize copy_thread(), get rid of clone(2) wrapper, switch to generic clone() take sys_fork/sys_vfork/sys_clone prototypes to linux/syscalls.h mn10300: switch to generic fork/vfork/clone h8300: switch to generic fork/vfork/clone tile: switch to generic clone() ...

mm: use vm_unmapped_area() on sparc32 architecture

2012-12-12T01:22:26+00:00

Update the sparc32 arch_get_unmapped_area function to make use of vm_unmapped_area() instead of implementing a brute force search.
