UM: implement syscall_get_arch() This patch defines syscall_get_arch() for the um platform. It adds a new syscall.h header file to define this. It copies the HOST_AUDIT_ARCH definition from ptrace.h. (that definition will be removed when we switch audit to use this new syscall_get_arch() function) Based-on-patch-by: Richard Briggs <rgb@redhat.com> Signed-off-by: Eric Paris <eparis@redhat.com> Cc: user-mode-linux-devel@lists.sourceforge.net

um: Add full asm/syscall.h support Add subarchitecture-independent implementation of asm-generic/syscall.h allowing access to user system call parameters and results: * syscall_get_nr() * syscall_rollback() * syscall_get_error() * syscall_get_return_value() * syscall_set_return_value() * syscall_get_arguments() * syscall_set_arguments() * syscall_get_arch() provided by arch/x86/um/asm/syscall.h This provides the necessary syscall helpers needed by HAVE_ARCH_SECCOMP_FILTER plus syscall_get_error(). This is inspired from Meredydd Luff's patch (https://gerrit.chromium.org/gerrit/21425).
