Merge branch 'parisc-3.18-1' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux
Pull parisc fix from Helge Deller: "This patch intentionally breaks the ABI on PARISC Linux! It assigns new numbers to SIGSTKFLT, SIGXCPU, SIGXFSZ and SIGSYS so that those are below 32 and thus leaves us with 32 RT signals like other Linux architectures (SIGRTMIN now becomes 32 instead of 37). Even if it breaks the ABI, it doesn't seem to have any visible impact on existing userspace applications. I was able to mix new kernel and/or glibc without impacting normal bootup. So, even if it breaks the ABI, the benefits (e.g. being able to use systemd on PARISC Linux) outperforms the minimal (if any) impact it gives. The patch has been discussed on the parisc kernel mailing list and the coresponding glibc patch will be committed by the parisc glibc maintainer after this patch went into 3.18. Some more background information about this patch is in the commit message" [ Side note: the "no regressions" rule has always been about *users*, not ABI's. You can change ABI's all you like, until somebody actually notices. At that point it gets reverted regardless of how good your reasons and excuses. And admittedly, with parisc, the distinct lack of many users makes that fairly unlikely anyway :^p - Linus ] * 'parisc-3.18-1' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux: parisc: Reduce SIGRTMIN from 37 to 32 to behave like other Linux architectures
