/* System call table for x86-64. */
Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

x86: Fix sys_call_table type in asm/syscall.h Make the sys_call_table type defined in asm/syscall.h match the definition in syscall_64.c v2: include asm/syscall.h in syscall_64.c too. I left uml alone because it doesn't have an syscall.h on its own and including the native one leads to other errors.

x86/syscalls: Add syscall entry qualifiers This will let us specify something like 'sys_xyz/foo' instead of 'sys_xyz' in the syscall table, where the 'foo' qualifier conveys some extra information to the C code. The intent is to allow things like sys_execve/ptregs to indicate that sys_execve() touches pt_regs.

x86: Generate system call tables and unistd_*.h from tables Generate system call tables and unistd_*.h automatically from the tables in arch/x86/syscalls. All other information, like NR_syscalls, is auto-generated, some of which is in asm-offsets_*.c. This allows us to keep all the system call information in one place, and allows for kernel space and user space to see different information; this is currently used for the ia32 system call numbers when building the 64-bit kernel, but will be used by the x32 ABI in the near future. This also removes some gratuitious differences between i386, x86-64 and ia32; in particular, now all system call tables are generated with the same mechanism. Cc: H. J.
