As there are no users left, we can remove cpu_relax_lowlatency.

For spinning loops people do often use barrier() or cpu_relax(). For most architectures cpu_relax and barrier are the same, but on some architectures cpu_relax can add some latency. For example on power,sparc64 and arc, cpu_relax can shift the CPU towards other hardware threads in an SMT environment. On s390 cpu_relax does even more, it uses an hypercall to the hypervisor to give up the timeslice.

tag 334917 = patch thanks Hi, I?ve fixed the m68k syscall of klibc and made it able to use six-argument syscalls like mmap2. However, I could not yet fully test it (only mostly; opendir() specifically fails) due to: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=47533 @m68k porters: Please have a look at the gcc bug as well. @klibc: Please apply the patch, it?s better than what we have, and

No need to duplicate the same define everywhere. Since the only user is stop-machine and the only provider is s390, we can use a default implementation of cpu_relax_yield in sched.h.

While the userspace function signature is int sigsuspend(const sigset_t *maskptr) there are several variants of how this is mapped into kernel functions: one for rt_sigsuspend and several, mutually incompatible, legacy ones, split by architectures. Before this commit, klibc did not care about that and passed maskptr as first and only argument to the syscall, leading to junk in other argument

The original goal of this patchset is to fix the bug reported by https://bugzilla.kernel.org/show_bug.cgi?id=53501 Now it has also been expanded to reduce common code used by memory initializion. This is the first part, which applies to v3.9-rc1. It introduces following common helper functions to simplify free_initmem() and free_initrd_mem() on different architectures:

This fixes a long standing issue where it was not possible to do "make usr/klibc/arch/x86_64/longjmp.o" in the kernel. The principle is that all .o files to be part of klibc are listed with klib-y. For each directory a klib.list file is made that specify all .o file and the final AR then adds all .o files to create libc.a. This patch introduce the infrastructure and converts x86_64 to

klibc fails to build on ia64 because it has neither fork nor the ppoll syscalls. This patch marks the former in SYSCALLS.def, and puts a guard wrapper around the ppoll definition in ppoll.c Should these calls return ENOSYS rather than simply not existing on some systems? If yes, please apply this and I'll follow up with a patch shortly that does ENOSYS for this and pselect at least.
