1599e8fc84 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.

a06c9bc064 x32: If configured, add x32 system calls to system call tables
If CONFIG_X86_X32_ABI is defined, add the x32 system calls to the
system call tables.

6630f11ba5 x32: Add x32 system calls to syscall/syscall_64.tbl
Split the 64-bit system calls into "64" (64-bit only) and "common"
(64-bit or x32) and add the x32 system call numbers.

303395ac3b 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.

b7641d2c83 x86-64, syscall: Adjust comment spacing and remove typo
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.

1965aae3c9 x86: Fix ASM_X86__ header guards
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.

a318631686 x86: consolidate header guards
This patch consolidates the header guard names which are also used
externally, i.e. in .c files.
