| Subject: arm: include asm/cacheflush.h in asm/hugetlb.h |
| Date: Sun, 13 Aug 2023 21:52:38 -0700 (PDT) |
| |
| Patch series "arch: include asm/cacheflush.h in asm/hugetlb.h". |
| |
| Three architectures are using PG_dcache_clean in their asm/hugetlb.h, |
| but relying on accident to include the asm/cacheflush.h which defines it. |
| |
| |
| This patch (of 3): |
| |
| PG_dcache_clean is used in asm/hugetlb.h but defined in asm/cacheflush.h: |
| builds rely on an accident of that being included via linux/mempolicy.h, |
| but better include it directly (like arch/sh/include/asm/hugetlb.h does). |
