Zhenhua Huang 558b8ee45f mm,kfence: decouple kfence from page granularity mapping judgement ... [ Upstream commit bfa7965b33ab79fc3b2f8adc14704075fe2416cd ] Kfence only needs its pool to be mapped as page granularity, if it is inited early. Previous judgement was a bit over protected. From [1], Mark suggested to "just map the KFENCE region a page granularity". So I decouple it from judgement and do page granularity mapping for kfence pool only. Need to be noticed that late init of kfence pool still requires page granularity mapping. Page granularity mapping in theory cost more(2M per 1GB) memory on arm64 platform. Like what I've tested on QEMU(emulated 1GB RAM) with gki_defconfig, also turning off rodata protection: Before: [root@liebao ]# cat /proc/meminfo MemTotal: 999484 kB After: [root@liebao ]# cat /proc/meminfo MemTotal: 1001480 kB To implement this, also relocate the kfence pool allocation before the linear mapping setting up, arm64_kfence_alloc_pool is to allocate phys addr, __kfence_pool is to be set after linear mapping set up.
