test04 in numa01.sh is using a wrong method to get the number of CPUs.
This results in:
numactl: cpu argument 9 is out of range
awk: cmd. line:1: fatal: cannot open file `/proc/4116/stat' for reading
(No such file or directory)
/opt/ltp/testcases/bin/numa01.sh: line 475: [: =: unary operator expected
awk: cmd. line:1: fatal: cannot open file `/proc/4116/stat' for reading
(No such file or directory)
/opt/ltp/testcases/bin/numa01.sh: line 481: [: -ne: unary operator expected
/opt/ltp/testcases/bin/numa01.sh: line 488: kill: (4116) - No such process
numa04 4 TBROK : Kill on process 4116 fails
Fix it by getting number of CPUs by grepping /proc/cpuinfo.
