The BKL was pushed into this function when it was converted to use the
unlocked_ioctl interface, but nothing that the function touches is
actually protected by the BKL. So just remove the BKL entirely, so that
we finally can get a realistic system build without the BKL being
enabled at all.

Detects RIO link to the already enumerated device and properly sets links
between device objects. Changes to the enumeration/discovery logic:
1. Use Master Enable bit to signal end of the enumeration - agents may
start their discovery process as soon as they see this bit set
(Component Tag register was used before for this purpose).
2. Enumerator sets Component Tag (!= 0) immediately during device
setup. This allows to identify the device if the redundant route
exists in a RIO system.

This set of RapidIO patches extends support for standard error recovery
mechanism and adds new IDT Gen2 sRIO switch devices - CPS-1848 and
CPS-1616. Implementation of the standard error-stopped state recovery
mechanism (as defined by the RapidIO specification) is required for the
new switches.
Version 2 of this set of patches addresses received comments and fixes an
error notification setup issue found in the idt_gen2.c after the first
version was released.
This patch:
Make RapidIO devices appear in /sys/devices/rapidio directory instead of
top of /sys/devices directory.

Fix a long standing bug with per device locking.
Each device has an associated spinlock for synchronizing access to
hardware and state information with the ISR. A single hardware card has
one or more devices.
Bug: Non ISR code correctly acquires and releases the per device lock.
ISR incorrectly always acquires and releases the lock of the first device
on the card.
The decoupled and list based nature of the ISR and deferred processing
interaction allowed this to work in normal operation. Exceptional events
like an application forcing hardware shutdown, reset, or reconfiguration
while active can trigger the bug.
Fixed ISR to acquire and release the per device lock.
One exception is manipulation of the GPIO card resource which is global
and effectively owned by the first device of the card. Non-ISR access to
GPIO resource is changed to use lock of first device on card.

This code is preceded by a call to framebuffer_alloc, which allocates
memory, so this memory should be freed before leaving the function in an
error case. out_release_framebuffer just frees the frame buffer and
returns.
A simplified version of the semantic match that finds this problem is:
(http://coccinelle.lip6.fr/)

fb_{read,write} access the framebuffer using lots of fb_{read,write}l's
but don't check that the file position is aligned which can cause problems
on some architectures which do not support unaligned accesses.
Since the operations are essentially memcpy_{from,to}io, new
fb_memcpy_{from,to}fb macros have been defined and these are used instead.
For Sparc, fb_{read,write} macros use sbus_{read,write}, so this defines
new sbus_memcpy_{from,to}io functions the same as memcpy_{from,to}io but
using sbus_{read,write}b instead of {read,write}b.

The function has an unsigned return type, but returns a negative constant
to indicate an error condition. The result of calling the function is
only tested by comparison to 0, and thus unsigned is not needed and can be
dropped from the return type.
A sematic match that finds this problem is as follows:

// <smpl>
@exists@
identifier f;
constant C;
@@
unsigned f(...)
{ <+...
* return -C;

I tested savagefb on 3 different Savage 4 cards:
Diamond Stealth III S520
Number Nine SR9
Datapath Horizon 2S (two savage chips on a PCI card)
it worked except the DDC which did not work on any of them.
Looking at the BIOS code, it does not use MMIO register 0xff20 but CRT
register 0xa0 or 0xb1 - depending on the chip revision and something in
register 0xa6. With this patch, DDC works fine on all 3 cards (even on
the second head of Horizon 2S - although it does not display anything as
it's misconfigured because of missing BIOS).

The CONFIG_FB_MATROX_G ifdef isn't necessary at this point, because it is
checked in an outer ifdef level already and has no effect here.

In this case the logic is very similar but the IRQs are not exposed and
the device is not picked up via PCI
