[PATCH v6 00/10] Intel Cache Allocation Technology

[Fenghua Yu]

From: Fenghua Yu <fenghua.yu@xxxxxxxxx>

This version is supposed to cover all comments from Thomas.

Patch 1-4, 6-9 of 18 v5 patches are in tip x86/cache branch. We
have rest of 10 patches in v6 on top of tip tree.

Change log in v6:

patch 1 (i.e. patch 5 in v5): Change max_cbm_val to cbm_mask.

patch 2 (i.e. patch 10 in v5): Change comments for rdt_find_domain and
domain_add_cpu() to explain why domain list is sorted by id. Change
the pos argument to optional in rdt_rind_domain and assign NULL to it
in caller domain_remove_cpu.

patch 3 (i.e. patch 11 in v5): Remove arg's type cast in
l3_qos_cfg_update(). Change the local variable declaration lines in
more readable way. Disable CDP in umount only when it's enabled. Fix
an error handling issue in rdt_mount.

patch 4 (i.e. patch 12 in v5): Change names from "num_closid" to
"num_closids" and from "cbm_val" to "cbm_mask" in res_info_files. Remove
the unused label "out" in rdtgroup_setup_root() and will add it later when
it's used.

patch 5 (i.e. patch 13 in v5): Init closid_free_map by minimal closid
instead of by maximum closid in all resources.

patch 6 (i.e. patch 14 in v5): Change local variable declaration lines
to more readable way.

patch 7 (i.e. patch 15 in v5): Change for_each_process to
for_each_process_thread

patch 8 (i.e. patch 16 in v5): Change local variable declaration lines
to more readable way.

patch 9 (i.e. patch 17 in v5): No change.

patch 10 (i.e. patch 18 in v5): No change.
