[PATCH] parisc: Drop HP-UX specifix fcntl and signal flags

[Helge Deller]

Those flags are nowhere used in the Linux kernel and were added when we
still wanted to support HP-UX in a compat mode. Since we never will
support HP-UX, drop those flags.

So, what about O_DSYNC? Either it should go away the same if it is HPUX only, 
or the comment needs to be fixed.

That's true.
I had it fixed already in my git tree:
https://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux.git/commit/?h=for-next&id=297f57686b3f634306b6a67a90d5a146392693c2
