Kohei Tarumizu 294395caac x86/resctrl: Fix to restore to original value when re-enabling hardware prefetch register ... [ Upstream commit 499c8bb4693d1c8d8f3d6dd38e5bdde3ff5bd906 ] The current pseudo_lock.c code overwrites the value of the MSR_MISC_FEATURE_CONTROL to 0 even if the original value is not 0. Therefore, modify it to save and restore the original values. Fixes: 018961ae55 ("x86/intel_rdt: Pseudo-lock region creation/removal core") Fixes: 443810fe61 ("x86/intel_rdt: Create debugfs files for pseudo-locking testing") Fixes: 8a2fc0e1bc ("x86/intel_rdt: More precise L2 hit/miss measurements") Signed-off-by: Kohei Tarumizu <tarumizu.kohei@fujitsu.com> Signed-off-by: Dave Hansen <dave.hansen@linux.intel.com> Acked-by: Reinette Chatre <reinette.chatre@intel.com> Link: https://lkml.kernel.org/r/eb660f3c2010b79a792c573c02d01e8e841206ad.1661358182.git.reinette.chatre@intel.com Signed-off-by: Sasha Levin <sashal@kernel.org>		2022-10-26 13:25:19 +02:00
