Hi Eric,
After merging the audit tree, today's linux-next build (sparc defconfig)
failed like this:
In file included from include/linux/audit.h:29:0,
from mm/mmap.c:33:
arch/sparc/include/asm/syscall.h: In function 'syscall_get_arch':
arch/sparc/include/asm/syscall.h:131:9: error: 'TIF_32BIT' undeclared (first use in this function)
arch/sparc/include/asm/syscall.h:131:9: note: each undeclared identifier is reported only once for each function it appears in
And many more ...
Caused by commit 374c0c054122 ("ARCH: AUDIT: implement syscall_get_arch
for all arches").
I applied this patch for today:

I swear I saw this and I fixed it. Drat. Do we want to do it this way?
Above in syscall_get_arguments() they use
#ifdef CONFIG_SPARC64
if (test_tsk_thread_flag(task, TIF_32BIT))
zero_extend = 1;
#endif
Is CONFIG_SPARC64 a better choice than:
defined(__sparc__) && defined(__arch64__)
Maybe even better would be to copy what you suggested in powerpc:

I have no idea, I just copied the test from thread_info.h.

That would be better, except ...

Shouldn't that be (1) ?
