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.

If CONFIG_X86_X32_ABI is defined, add the x32 system calls to the system call tables. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
Split the 64-bit system calls into "64" (64-bit only) and "common" (64-bit or x32) and add the x32 system call numbers. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
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.

Adjust spacing for comment so that it matches the multiline comment style used in the rest of the kernel, and remove word duplication. It is not really clear what version of gcc this refers to, but the extra & doesn't cause any harm, so there is no reason to remove it. Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>
Change header guards named "ASM_X86__*" to "_ASM_X86_*" since: a. the double underscore is ugly and pointless. b. no leading underscore violates namespace constraints. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
This patch consolidates the header guard names which are also used externally, i.e. in .c files. Signed-off-by: Vegard Nossum <vegard.nossum@gmail.com>
