This patch updates the Option Card driver:
- remove a deadlock
- add sponsor notice
- add new card
- renamed the device to what's usually printed on it
- removed some dead code
- clean up a bunch of irregular whitespace (end-of-line, tabs)
Also add a MAINTAINERS entry for the Option Card driver.

Minimal patch removing uses of ROOT_DEV; next patch unexports it. I've
opposed this, but I've planned to reintroduce the functionality without using
ROOT_DEV.

This patch makes the command:
make ARCH=um SUBARCH=i386
work on x86_64 hosts (with support for building 32-bit binaries). This is
especially needed since 64-bit UMLs don't support 32-bit emulation for guest
binaries, currently. This has been tested in all possible cases and works.
Only exception is that I've built but not tested a 64-bit binary, because I
hadn't a 64-bit filesystem available.

The pcap support was not working because of some linking problems (expressing
the construct in Kbuild was a bit difficult) and because there was no user
request. Now that this has come back, here's the support.
This has been tested and works on both 32 and 64-bit hosts, even when
"cross-"building 32-bit binaries.

1) Cleanup an ugly hyper-nested code in Makefile (now only the arith.
expression is passed through the host bash).
2) Fix a problem with GCC 2.95: according to a report from Raphael Bossek,
.remap_data : { arch/um/sys-SUBARCH/unmap_fin.o (.data .bss) } is expanded
into: .remap_data : { arch/um/sys-i386 /unmap_fin.o (.data .bss) }
(because I didn't use ## to join the two tokens), thus stopping linking. Pass
the whole path from the Makefile as a simple and nice fix.

*) Reorganize the two cases of sys_modify_ldt to share all the reasonably
common code.
*) Avoid memory allocation when unneeded (i.e. when we are writing and the
passed buffer size is known), thus not returning ENOMEM (which isn't
allowed for this syscall, even if there is no strict "specification").
*) Add copy_{from,to}_user to modify_ldt for TT mode.

A big bug has been diagnosed on hosts running the SKAS patch and built with
CONFIG_REGPARM, due to some missing prevent_tail_call().
On these hosts, this workaround is needed to avoid triggering that bug,
because "to" is kept by GCC only in EBX, which is corrupted at the return of
mmap2().
Since to trigger this bug int 0x80 must be used when doing the call, it rarely
manifests itself, so I'd prefer to get this merged to workaround that host
bug, since it should cause no functional change. Still, you might prefer to
drop it, I'll leave this to you.

Russell King <rmk+lkml@arm.linux.org.uk>
This construct is refused by GCC 4, so here's the (corrected) fix. Thanks to
Russell for noticing a stupid mistake I did when first sending this.
As he noted, the code is largely suboptimal however it currently works, and
will be fixed shortly. Just read the access_ok check on fp which is NULL, or
the pointer arithmetic below which should be done with a cast to void*:
frame = (struct rt_sigframe __user *)
round_down(stack_top - sizeof(struct rt_sigframe), 16) - 8;
The code shows clearly that has been taken from
arch/x86_64/kernel/signal.c:setup_rt_frame(), maybe in a bit of a hurry.

XPC calls smp_processor_id() twice from xpc_setup_infrastructure() with
preemption enabled, which gets flagged if 'DEBUG_PREEMPT=y'. This patch
replaces the two calls to smp_processor_id() by a single call to
raw_smp_processor_id() since any CPU within the partition will do.

Add special case for the POSIX_FADV_DONTNEED and POSIX_FADV_NOREUSE hint
values for s390-64. The user space values in the s390-64 glibc headers for
these two defines have always been 6 and 7 instead of 4 and 5. All 64 bit
applications therefore use the "wrong" values. To get these applications
working without recompiling the kernel needs to accept the "wrong" values.
Since the values for s390-31 are 4 and 5 the compat wrapper for fadvise64
and fadvise64_64 need to rewrite the values for 31 bit system calls.
