2018-04-13or1k: add F_{DUPFD_CLOEXEC, SETPIPE_SZ, GETPIPE_SZ}Thomas Petazzoni
Those definitions exist on all other architectures, but were not present in or1k specific headers when or1k support was merged. On the kernel side, their support is completely architecture independent, so we just need those definitions to make those fcntl() calls available on or1k.

2018-01-15or1k: Use new common syscall() implementationStafford Horne
Now that the common syscall implementation supports vararg calling conventions we can safely use it on OpenRISC. This saves a bit of code in the openrisc implementation. Signed-off-by: Stafford Horne <shorne@gmail.com>
2017-12-10or1k: syscall: Pass arguments on the stackJoel Stanley
Busybox internally calls syscall(2). - in unistd.h defined something like int syscall(nr, ....) - in syscall.c (common) implemented as int syscall(nr, arg1, arg3, arg3, arg4, arg5, arg6) This will not work, busybox thinks syscall should have varargs calling conventions. But it doesnt in the uclibc implementation so no args go through. Most architectures this will work. But on openrisc varargs are all sent on the stack. Regular args are passed in registers.

2017-11-25setjmp/longjmp saves only non-call clobbered regsChristian Svensson
Previously we saved everything, but we only need to save the registers that are promised to be untouched by the setjmp call.

2015-12-07add definitions for O_PATHWaldemar Brodkorb
Only alpha, hppa and sparc need non-default value.
2015-12-05remove __UCLIBC_ASM_GLOBAL_DIRECTIVE__Waldemar Brodkorb
.globl can be used for every architecture so remove the define. Sync with GNU C library.
2015-12-05remove __UCLIBC_HAVE_ASM_GLOBAL_DOT_NAME__Waldemar Brodkorb
It's even no longer required for non-ported ppc64 architecture. Sync with GNU C library. This simplify the macros in include/libc-symbols.h.
