* fix posix_fadvise syscall args on powerpc, unify with arm fixRich Felker2016-07-011-0/+2
| | | | | | | | | commit 6d38c9cf80f47623e5e48190046673bbd0dc410b provided an arm-specific version of posix_fadvise to address the alternate argument order the kernel expects on arm, but neglected to address that powerpc (32-bit) has the same issue. instead of having arch variant files in duplicate, simply put the alternate version in the top-level file under the control of a macro defined in syscall_arch.h.
* unify non-inline version of syscall code across archsRich Felker2014-11-221-36/+2
| | | | | | | | | | | | | | except powerpc, which still lacks inline syscalls simply because nobody has written the code, these are all fallbacks used to work around a clang bug that probably does not exist in versions of clang that can compile musl. however, it's useful to have the generic non-inline code anyway, as it eases the task of porting to new archs: writing inline syscall code is now optional. this approach could also help support compilers which don't understand inline asm or lack support for the needed register constraints. mips could not be unified because it has special fixup code for broken layout of the kernel's struct stat.

* remove __SYSCALL_SSLEN arch macro in favor of using public _NSIGRich Felker2013-03-261-2/+0
| | | | | | | | | | | | | | the issue at hand is that many syscalls require as an argument the kernel-ABI size of sigset_t, intended to allow the kernel to switch to a larger sigset_t in the future. previously, each arch was defining this size in syscall_arch.h, which was redundant with the definition of _NSIG in bits/signal.h. as it's used in some not-quite-portable application code as well, _NSIG is much more likely to be recognized and understood immediately by someone reading the code, and it's also shorter and less cluttered. note that _NSIG is actually 65/129, not 64/128, but the division takes care of throwing away the off-by-one part.
