Heiko Carstens (1): compat: fix compile breakage on s390
It looks like we need the same fix as for 2.6.32.59:
arch/s390/kernel/setup.c: In function 'setup_addressing_mode':
arch/s390/kernel/setup.c:328: error: 'PSW32_ASC_PRIMARY' undeclared
(first use in this function)
arch/s390/kernel/setup.c:328: error: (Each undeclared identifier is
reported only once
arch/s390/kernel/setup.c:328: error: for each function it appears in.)
And when that one is fixed, there is another error:
drivers/s390/char/fs3270.c: In function 'fs3270_ioctl':
drivers/s390/char/fs3270.c:335: error: implicit declaration of function
'compat_ptr'
drivers/s390/char/fs3270.c:335: warning: assignment makes pointer from
integer without a cast
Ick, have a patch for this?
This one is declared in arch/s390/include/asm/compat.h:

static inline void __user *compat_ptr(compat_uptr_t uptr)
{
        return (void __user *)(unsigned long)(uptr & 0x7fffffffUL);
}

In 2.6.32, fs3270.c include linux/compat.h. In 3.0 it includes asm/compat.h
instead. I would have thought the later would have been enough.
But it was changed to linux/compat.h in 3.0.24 -- that's why it doesn't
build. So the same fix as for setup.c should help here.
It is attached. With that patch (and the previous one), s390 builds fine
now.

thanks,
