2018-10-25pmalloc: don't lock 4K pages if we don't have access to pagemapDamjan Marion2-6/+30
Without pagemap access only way to do DMA to physmem is by using IOMMU. In such case VFIO will take care for preventing paging of such memory so we don't need to lock here. Change-Id: Ica9c20659fba3ea3c96202eb5f7d29c43b313fa9 Signed-off-by: Damjan Marion <damarion@cisco.com>

Currently, there are three variants available on aarch64, qdf24xx, thunderx2t99, and cortex-a72. -DCLIB_N_PREFETCHES is passed to source code to select dual/quad implementation. Besides, different compiler options are applied on these critical functions. gcc-7.3.0 reports ICE(internal compiler error) with -mtune=thunderx2t99, so -mtune=thunderx2t99 is enabled only when gcc version is greater than 7.3.0 Cavium ThunderX2, Impermenter 0x43, Part 0x0af -march=armv8-a+crc+crypto -mtune=thunderx2t99 Qualcomm Centriq 2400, Impermenter 0x51, Part 0xc00 -march=armv8.1-a+crc+crypto -mtune=qdf24xx Cortex-A72, Impermenter 0x41, Part 0xd08 -march=armv8-a+crc+crypto -mtune=cortex-a72 Change-Id: Id5649c6325c1e642d0fd42535e3908793b13e02a Signed-off-by: Lijian Zhang <Lijian.Zhang@arm.com> Reviewed-by: Sirshak Das <sirshak.das@arm.com> Reviewed-by: Honnappa Nagarahalli <Honnappa.Nagarahalli@arm.com>

ffb14b9554afa1e58c3657e0c91dda3135008274 has changed the semantics of alloc_arena_next to become an offset off alloc_arena, but in the available memory check in BV (alloc_aligned) it still treats it as a virtual address, resulting in the check always succeeding, thus over a prolonged period bihash arena allocator potentially overwriting whatever is following the arena.
