Subject: [PATCH AUTOSEL 5.17 19/48] selftests/resctrl: Change the default limited time to 120 seconds

From: Shaopeng Tan <tan.shaopeng@...fujitsu.com>

[ Upstream commit e2e3fb6ef0d6548defbe0be6e092397aaa92f3a1 ]

When testing on a Intel(R) Xeon(R) Gold 6254 CPU @ 3.10GHz the resctrl
selftests fail due to timeout after exceeding the default time limit of
45 seconds. On this system the test takes about 68 seconds.
Since the failing test by default accesses a fixed size of memory, the
execution time should not vary significantly between different environment.
A new default of 120 seconds should be sufficient yet easy to customize
with the introduction of the "settings" file for reference.
