[PATCH v7 OLK-5.10 0/3] arm64: support page mapping percpu first chunk allocator
by Kaixiong Yu 13 Nov '24

13 Nov '24

Percpu embedded first chunk allocator is the firstly option, but it could fails on ARM64 when turning on numa with CONFIG_KASAN=y. Let's implement page mapping percpu first chunk allocator as a fallback to the embedding allocator to increase the robustness of the system. Also fix a crash when both NEED_PER_CPU_PAGE_FIRST_CHUNK and KASAN_VMALLOC enabled. After merging this patch set, the ARM64 machine can start and work normally.

Align with the original variables to prevent others from inserting new variables before is_check in the future. V3: Add a mainline patch to fix commit 4759ff71f23e(exec: __FMODE_EXEC instead of in_execve for LSMs).
