[v2] ice: use better bitmap API

[PATCH v2 0/4] ice: use better bitmap API

Posted by Yury Norov 1 month, 2 weeks ago

Use better bitmap API where appropriate. Patches #3,4 may be applied
separately.

v1: https://lore.kernel.org/all/20251223162303.434659-1-yury.norov@gmail.com/
v2:
 - new v2#4;
 - add documentation line (Simon);

Yury Norov (4):
  bitmap: introduce bitmap_weighted_xor()
  ice: use bitmap_weighted_xor() in ice_find_free_recp_res_idx()
  ice: use bitmap_empty() in ice_vf_has_no_qs_ena
  drm/xe: switch xe_pagefault_queue_init() to using bitmap_weighted_or()
