All definitions of syscalls in x86 except for those patched here have already been using the appropriate SYSCALL_DEFINE*. Signed-off-by: Michael Tautschnig Cc: Thomas Gleixner Cc: Ingo Molnar Cc: H. Peter Anvin Cc:

[PATCH v2] x86: always use SYSCALL_DEFINE*

All syscall arguments are passed in as types of the same byte size as unsigned long (width of full registers). Using a smaller type without a cast may result in losing bits of information. SYSCALL_DEFINE* introduce adequate type casts. All definitions of syscalls in x86 except for those patched

bin2c is used to create a valid C file out of a binary file where two symbols will be globally defined: and _size. is passed as the first parameter of the host binary. Building using goto-cc reported that the purgatory binary code (the only current user of this utility) declares
