c6c27e3d84 selftests/powerpc: Use req_max_processed_len from sysfs NX capabilities 
On PowerVM, the hypervisor defines the maximum buffer length for
each NX request and the kernel exported this value via sysfs.

This patch reads this value if the sysfs entry is available and
is used to limit the request length.

f0812f6ca8 selftests/powerpc: update .gitignore 
I did an in-place build of the self-tests and found that it left
the tree dirty.

Add missed test binaries to .gitignore

f0479c4bcb selftests/powerpc: Use proper error code to check fault address 
ERR_NX_TRANSLATION(CSB.CC=5) is for internal to VAS for fault handling
and should not used by OS. ERR_NX_AT_FAULT(CSB.CC=250) is the proper
error code should be reported by OS when NX encounters address
translation failure.

This patch uses CC=250 to determine the fault address when the request
is not successful.
