[PATCH v2 14/24] x86/resctrl: Rename update_domains() resctrl_arch_update_domains()

James Morse
2021-03-12T18:01:08Z

update_domains() merges the staged configuration changes into the
arch codes configuration array. Rename to make it clear its part of the
arch code interface to resctrl.

Changes since v1:
* The closid is no longer staged as from resctrl its always going to be
the same number even with CDP.
