selftests/powerpc: Use req_max_processed_len from sysfs NX capabilities

2021-06-25T04:47:19Z

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.

selftests/powerpc: Use proper error code to check fault address

2020-07-15T13:10:17Z

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.
