create a file descriptor for accepting signals
compat_sys_signalfd(int ufd, sigset_t *user_mask, size_t sizemask)| number | 321 (0x141) |
|---|---|
| abi | i386 |
| kconfig | CONFIG_SIGNALFD |
| entry point | compat_sys_signalfd |
| since | Linux 3.3 or earlier (3.3 is the first release scanned for ia32) |

Registers
| register | value |
|---|---|
eax | 321, the syscall number |
ebx | int ufd |
ecx | sigset_t *user_mask |
edx | size_t sizemask |
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.
