Subject: scsi: mpt3sas: Remove CPU arch check to determine perf_mode
Patch-mainline: v5.3-rc1
Git-commit: 381abbd1f7f978471722784895d1ff184ef86929
References: bsc#1143738
Currently default perf_mode is set to 'balanced' on Intel architecture
machines and on other machines default perf_mode is set to 'latency' mode.
This CPU architecture check is removed and the default perf_mode mode is
set to 'balanced' mode on all machines.
User can choose the required performance mode using perf_mode module
parameter.
