DC invokes DC_FPU_START/END in multiple parts of the code; this can create a situation where we invoke this FPU operation in a nested way or exit too early. For avoiding this situation, this commit adds a mechanism where dc_fpu_begin/end manages the access to kernel_fpu_begin/end. Change since V3: - Christian: Move PPC64 code to dc_fpu_begin/end. Change since V2: - Christian: Do not use this_cpu_* between get/put_cpu_ptr(). Change since V1: - Use a better variable names - Use get_cpu_ptr and put_cpu_ptr to better balance preemption enable and disable Cc: Harry Wentland <harry.wentland@amd.com> Cc: Anson Jacob <Anson.Jacob@amd.com> Cc: Christian König <christian.koenig@amd.com> Cc: Hersen Wu <hersenxs.wu@amd.com> Cc: Aric Cyr <aric.cyr@amd.com> Cc: Jun Lei <jun.lei@amd.com> Cc: Dmytro Laktyushkin <dmytro.laktyushkin@amd.com> Cc: Qingqing Zhuo <qingqing.zhuo@amd.com> Signed-off-by: Rodrigo Siqueira <Rodrigo.Siqueira@amd.com> Reviewed-by: Christian König <christian.koenig@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
