parisc: Add MAP_UNINITIALIZED define

2020-10-15T06:10:39Z

We will not allow unitialized anon mmaps, but we need this define to prevent build errors, e.g. the debian foot package. Suggested-by: John David Anglin Signed-off-by: Helge Deller

parisc: Improve spinlock handling

2020-10-15T06:10:39Z

Use READ_ONCE() to check if spinlock is locked. The other changes are cleanups. Signed-off-by: John David Anglin Signed-off-by: Helge Deller

parisc: Switch to more fine grained lws locks

2020-10-15T06:10:39Z

Increase the number of lws locks to 256 entries (instead of 16) and choose lock entry based on bits 3-11 (instead of 4-7) of the relevant address. With this change we archieve more fine-grained locking in futex syscalls and thus reduce the number of possible stalls. Signed-off-by: John David Anglin Signed-off-by: Helge Deller

parisc: Mark pointers volatile in xchg8(), xchg32() and __xchg64()

2020-10-15T06:10:39Z

Let the complier treat the pointers volatile to ensure that they get accessed atomicly. Signed-off-by: John David Anglin Signed-off-by: Helge Deller

parisc: Add alternative patching to synchronize_caches define

2020-10-15T06:10:38Z

This change allows the sync barrier instruction to be patched to a nop. Signed-off-by: John David Anglin Signed-off-by: Helge Deller

parisc: Drop useless comments in uapi/asm/signal.h

parisc: Define O_NONBLOCK to become 000200000

2020-10-15T06:10:38Z

HPUX has separate NDELAY & NONBLOCK values. In the past we wanted to be able to run HP-UX binaries natively on parisc Linux which is why we defined O_NONBLOCK to 000200004 to distinguish NDELAY & NONBLOCK bits. But with 2 bits set in this bitmask we often ran into compatibility issues with other Linux applications which often only test one bit (or even compare the values). To avoid such issues in the future, this patch changes O_NONBLOCK to become 000200000. That way old programs will still be functional, and for new programs we now have only one bit set. Update the comment about SOCK_NONBLOCK too. Signed-off-by: Helge Deller

parisc: Drop HP-UX specific fcntl and signal flags

2020-10-15T06:10:37Z

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. Signed-off-by: Helge Deller
