futex_wait on ia32

sys_futex_wait(void *uaddr, unsigned long val, unsigned long mask, unsigned int flags, struct __kernel_timespec *timespec, clockid_t clockid)

Registers

register	value
`eax`	455, the syscall number
`ebx`	void *uaddr
`ecx`	unsigned long val
`edx`	unsigned long mask
`esi`	unsigned int flags
`edi`	struct __kernel_timespec *timespec
`ebp`	clockid_t clockid
`eax`	the return value

Then run int 0x80 to enter the kernel.

This compat ABI is only available when the kernel is built with CONFIG_IA32_EMULATION.
