X86 : system call

2021-12-11 Thread Muni Sekhar
Hi all, 32-bit system call numbers and entry vectors are defined in the format "". What is the difference between and ? The abi is always "i386" for arch/x86/entry/syscalls/syscall_32.tbl, whereas for 64-bit(arch/x86/entry/syscalls/syscall_64.tbl) it is used as "common" and "64", "x32".
