Nancy <nancydreaming@gmail.com> reported: Case "endian_switch01" FAIL on IBM Power 6 machine. The case failed on IBM JS22, p570 and p550. Is that the case bug or the OS bug? Thank you!. Subrata Modak <subrata@linux.vnet.ibm.com> replied: This will fail for all POWER machines which are not P6 & above, and, for all other archs. However, for other archs, it will throw you appropriate message like:
$./testcases/bin/endian_switch01
endian_switch01 1 CONF : This system does not support running of switch() syscall
In P6 (and above), even it will fail if the kernel is not 2.6.26 & above. The support for this syscall was added only from then. Please see: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=745a14cc264b1832c638e41812e0cb04328b2db1. If you are running 2.6.26 on p6, then we need to investigate why this is failing, else, i would prefer to merge the following patch for avoiding to test in systems where the switch() support is not available at the first place itself.
