This patch adds a new primitive crypto_grab_spawn which is meant
to replace crypto_init_spawn and crypto_init_spawn2. Under the

crypto: nx - add hardware 842 crypto comp alg
Add crypto compression alg for 842 hardware compression and decompression,

This uses only the PowerPC coprocessor hardware for 842 compression. It
also uses the hardware for decompression, but if the hardware fails it will
fall back to the 842 software decompression library, so that decompression
never fails (for valid 842 compressed buffers). A header must be used in

Due to the header this driver adds, compressed buffers it creates cannot be
directly passed to the 842 software library for decompression. However,

tracing: remove use of seq_printf return value
The seq_printf return value, because it's frequently misused,
will eventually be converted to void.
See: commit 1f33c41c03da ("seq_file: Rename seq_overflow() to
seq_has_overflowed() and make public")
Miscellanea:
o Remove unused return value from trace_lookup_stack
