25c619e59b395a8c Brian Gerst 2020-03-13 15 * Instead of the generic __SYSCALL_DEFINEx() definition, the x86 version takes
25c619e59b395a8c Brian Gerst 2020-03-13 16 * struct pt_regs *regs as the only argument of the syscall stub(s) named as:
25c619e59b395a8c Brian Gerst 2020-03-13 17 * __x64_sys_*() - 64-bit native syscall
25c619e59b395a8c Brian Gerst 2020-03-13 18 * __ia32_sys_*() - 32-bit native syscall or common compat syscall
25c619e59b395a8c Brian Gerst 2020-03-13 19 * __ia32_compat_sys_*() - 32-bit compat syscall
25c619e59b395a8c Brian Gerst 2020-03-13 20 * __x32_compat_sys_*() - 64-bit X32 compat syscall

25c619e59b395a8c Brian Gerst 2020-03-13 22 * The registers are decoded according to the ABI:
25c619e59b395a8c Brian Gerst 2020-03-13 23 * 64-bit: RDI, RSI, RDX, R10, R8, R9

25c619e59b395a8c Brian Gerst 2020-03-13 25 *
25c619e59b395a8c Brian Gerst 2020-03-13 26 * The stub then passes the decoded arguments to the __se_sys_*() wrapper to
25c619e59b395a8c Brian Gerst 2020-03-13 27 * perform sign-extension (omitted for zero-argument syscalls). Finally the
25c619e59b395a8c Brian Gerst 2020-03-13 28 * arguments are passed to the __do_sys_*() function which is the actual
25c619e59b395a8c Brian Gerst 2020-03-13 29 * syscall. These wrappers are marked as inline so the compiler can optimize
25c619e59b395a8c Brian Gerst 2020-03-13 30 * the functions where appropriate.
