kexec_load on ia32

load a new kernel for later execution

compat_sys_kexec_load(unsigned long entry, unsigned long nr_segments, struct kexec_segment *segments, unsigned long flags)

number	283 (0x11b)
abi	i386
kconfig	`CONFIG_KEXEC`
entry point	`compat_sys_kexec_load`
since	Linux 3.3 or earlier (3.3 is the first release scanned for ia32)
man page	kexec_load(2)
source	elixir.bootlin.com

Registers

register	value
`eax`	283, the syscall number
`ebx`	unsigned long entry
`ecx`	unsigned long nr_segments
`edx`	struct kexec_segment *segments
`esi`	unsigned long flags
`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.
