2013-03-21arm64: klib: Optimised atomic bitopsCatalin Marinas1-5/+8
This patch implements the AArch64-specific atomic bitops functions using exclusive memory accesses to avoid locking. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
2013-03-21arm64: klib: Optimised string functionsCatalin Marinas1-0/+2
This patch introduces AArch64-specific string functions (strchr, strrchr). Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
2013-03-21arm64: klib: Optimised memory functionsCatalin Marinas1-0/+6
This patch introduces AArch64-specific memory functions (memcpy, memmove, memchr, memset). These functions are not optimised for any CPU implementation but can be used as a starting point once hardware is available. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
2013-03-18arm64: Fix build error with !SMPCatalin Marinas1-0/+2
The __atomic_hash is only defined when SMP is enabled but the arm64ksyms.c exports it even for the UP case. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
