Al Viro	e0fd18ce11	arm64: get rid of fork/vfork/clone wrappers ... [fixes from Catalin Marinas folded] Acked-by: Catalin Marinas <catalin.marinas@arm.com> Tested-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>	2012-10-22 18:14:17 -04:00
Catalin Marinas	c34501d21b	arm64: Use generic kernel_thread() implementation ... This patch enables CONFIG_GENERIC_KERNEL_THREAD on arm64, changes copy_threads to cope with kernel threads creation and adapts ret_from_fork accordingly. The arm64-specific kernel_thread implementation is no longer needed. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>	2012-10-17 14:33:31 +01:00
Catalin Marinas	b3901d54dc	arm64: Process management ... The patch adds support for thread creation and context switching. The context switching CPU specific code is introduced with the CPU support patch (part of the arch/arm64/mm/proc.S file). AArch64 supports ASID-tagged TLBs and the ASID can be either 8 or 16-bit wide (detectable via the ID_AA64AFR0_EL1 register).
