[PATCH 0/4] selftests, sysctl, lib: Fix prime_numbers and sysctl test to run

[Masami Hiramatsu <mhiramat@kernel.org>]

Hi,

Recently, I found some tests were always skipped.
Here is a series of patches to fix those issues.

The prime_numbers test is skipped in some cases because
prime_numbers.ko is not always compiled.
Since the CONFIG_PRIME_NUMBERS is not independently
configurable item (it has no title and help), it is enabled
only if other configs (DRM_DEBUG_SELFTEST etc.) select it.

To fix this issue, I added a title and help for
CONFIG_PRIME_NUMBERS.

The sysctl test is skipped because
 - selftests/sysctl/config requires CONFIG_TEST_SYSCTL=y. But
   since lib/test_sysctl.c doesn't use module_init(), the
   test_syscall is not listed under /sys/module/ and the 
   test script gives up.
 - Even if we make CONFIG_TEST_SYSCTL=m, the test script checks
   /sys/modules/test_sysctl before loading module and gives up.
 - Ayway, since the test module introduces useless sysctl
   interface to the kernel, it would better be a module.

This series includes fixes for above 3 points.
 - Fix lib/test_sysctl.c to use module_init()
 - Fix tools/testing/selftests/sysctl/sysctl.sh to try to load
   test module if it is not loaded (nor embedded).
 - Fix tools/testing/selftests/sysctl/config to require
   CONFIG_TEST_SYSCTL=m, not y.

Thank you,

---
