2012-02-20x32: Generate <asm/unistd_64_x32.h>H. Peter Anvin
Generate macros for the *kernel* code to use to refer to x32 system calls. These have an __NR_x32_ prefix and do not include __X32_SYSCALL_BIT. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
2012-02-20x32: Generate <asm/unistd_x32.h>H. Peter Anvin
Generate <asm/unistd_x32.h>; this exports x32 system call numbers to user space. [ v2: Enclose all arguments to syshdr in '' so empty arguments aren't dropped on the floor. ] Signed-off-by: H. Peter Anvin <hpa@zytor.com>
2012-02-20x32: Add x32 system calls to syscall/syscall_64.tblH. Peter Anvin
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>
2012-02-20x86-64, ia32: Drop sys32_rt_sigprocmaskH. Peter Anvin
On x86, the only difference between sys_rt_sigprocmask and sys32_rt_sigprocmask is the alignment of the data structures. However, x86 allows data accesses with arbitrary alignment, and therefore there is no reason for this code to be different. Reported-by: Gregory M. Lueck <gregory.m.lueck@intel.com> Signed-off-by: H. Peter Anvin <hpa@zytor.com>
2011-11-18x86, syscall: Allow syscall offset to be symbolicH. Peter Anvin
Allow the specified syscall offset to be symbolic, e.g. a macro. For offset system calls, this if nothing else makes the generated code easier to read. Suggested-by: H. J. Lu <hjl.tools@gmail.com> Link: http://lkml.kernel.org/r/1321569446-20433-7-git-send-email-hpa@linux.intel.com Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>
2011-11-18x86: Simplify syscallhdr.shH. Peter Anvin
Simplify syscallhdr.sh by letting grep sort out the ABIs that we want, rather than relying on manual list matching. This is safe since the ABI strings already have to consist only of characters which are valid in C macro names.

2011-11-17x86: Machine-readable syscall tables and scripts to process themH. Peter Anvin
Create a simple set of syscall tables and scripts to turn them into both header files (unistd_*.h) and macros for generating the system call tables. Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>
