* [PATCH] ARM:mm: define arch-specific IOREMAP_MAX_ORDER only in !SMP && !LPAE case [not found] <1441680050-50490-1-git-send-email-zhenzhang.zhang@huawei.com> @ 2015-09-08 2:45 ` Zhang Zhen 0 siblings, 0 replies; 10+ messages in thread From: Zhang Zhen @ 2015-09-08 2:45 UTC (permalink / raw) To: linux-arm-kernel The arch-specific IOREMAP_MAX_ORDER is introduced in commit: ff0daca([ARM] Add section support to ioremap) and commit: a069c89 ([ARM] 3705/1: add supersection support to ioremap()). But supersections and sections mappings are only used in !SMP && !LPAE case. Otherwise, mapping is created using the usual 4K pages. In most cases without !SMP && !LPAE, the big alignment cause high fragmentation issue in vmalloc area. Here we use arch-specific IOREMAP_MAX_ORDER only in !SMP && !LPAE case, otherwise use generic IOREMAP_MAX_ORDER in include/linux/vmalloc.h.
