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 ]
