17 syscall calling sequence\ [1]_ matches the Power Architecture 64-bit ELF ABI
28 There is a maximum of 6 integer parameters to a syscall, passed in r3-r8.
34 clear, the syscall succeeded and r3 is the return value. When cr0.SO is set,
35 the syscall failed and r3 is the error value (that normally corresponds to
90 If the processor is in suspended state when a syscall is made, the syscall
91 will be performed as normal, and will return as normal. The syscall will be
105 transactional state and the syscall will proceed as in the case of a
106 suspended state syscall, and will resume the transactional state before
