commit 4f4ffc3a5398ef9bdbb32db04756d7d34e356fcf upstream.
automount-support is broken on the parisc architecture, because the existing
#if list does not include a check for defined(__hppa__). The HPPA (parisc)
architecture is similiar to other 64bit Linux targets where we have to define
autofs_wqt_t (which is passed back and forth to user space) as int type which
has a size of 32bit across 32 and 64bit kernels.
During the discussion on the mailing list, H. Peter Anvin suggested to invert
the #if list since only specific platforms (specifically those who do not have
a 32bit userspace, like IA64 and Alpha) should have autofs_wqt_t as unsigned
long type.
This suggestion is probably the best way to go, since Arm64 (and maybe others?)
seems to have a non-working automounter. So in the long run even for other new
upcoming architectures this inverted check seem to be the best solution, since
it will not require them to change this #if again (unless they are 64bit only).

Handling of autofs ioctl numbers does not need to be generic
and can easily be done directly in autofs itself.
This also pushes the BKL into autofs and autofs4 ioctl
methods.

fix the following 'make headers_check' warnings:
usr/include/linux/auto_fs.h:17: include of <linux/types.h> is preferred over <asm/types.h>

autofs_dev-ioctl.h is included by both the kernel module and user space tools
and it includes two kernel header files. Compiles work if the kernel headers
are installed but fail otherwise.

1) Add __s390__ to the list of architectures that use unsigned int as
type for rautofs_wqt_t. __s390__ is defined for both 31-bit and 64-bit
linux for s/390. Both architectures are fine with unsigned int since
sizeof(unsigned int) == sizeof(unsigned long) for 31 bit s/390.
2) Remove early initialization call ccwcache_init(). It doesn't exists
anymore.
3) Remove special case for irq_stat. We moved the irq_stat structure out
of the lowcore.
4) Replace acquire_console_sem with down_trylock & return to avoid an
endless trap loop if console_unblank is called from interrupt context
and the console semaphore is taken.

Anton Blanchard <anton@samba.org>: Fix autofs on ppc64:
Define autofs_wqt_t to be an int on ppc64, just like the other mixed
32/64 bit archs do.

Minor patch for the x86-64 32bit emulation. Originally proposed by hpa and it
makes autofs 32bit/64bit clean for x86-64
