Trying to compile the v850 port brings many compile errors, one of them exists
since at least kernel 2.6.19.
There also seems to be noone willing to bring this port back into a usable
state.
This patch therefore removes the v850 port.
If anyone ever decides to revive the v850 port the code will still be
available from older kernels, and it wouldn't be impossible for the port to
reenter the kernel if it would become actively maintained again.

During the recent discussion of taking 'volatile' off of the spinlock, I
noticed that while most arches #define cpu_relax() such that it implies
barrier(), some arches define cpu_relax() to be empty.
This patch changes the definition of cpu_relax() for frv, h8300, m68knommu,
sh, sh64, v850 and xtensa from an empty while(0) to the compiler barrier().

"extern inline" doesn't make much sense.

- Move MCA_bus declaration from <asm/processor.h> to <linux/mca.h>
- Define it in mca.c, not setup.c
- EXPORT_SYMBOL it at the site of its definition.
- Fix up random files to include <linux/mca.h> for the use of the MCA_bus
symbol
- Delete some unnecessary ifdefs.
- Delete some unneeded comments.

When I change the setting of CONFIG_EISA, everything rebuilds. This is
because EISA_bus is declared in <asm/processor.h> which is implicitly
included by just about everything. This is a silly place to declare it,
so this patch moves it to include/linux/eisa.h.
While I'm at it, I also move the variable definition to
drivers/eisa/eisa-bus.c. The rest of this patch is fixing up the fallout
from having to include <linux/eisa.h> if you use EISA_bus.

Some updated copyright noticed and an unnecessary variable deleted.

This allows us to avoid having to use atomic updates for the lazy FP
status setting, since we don't have to worry about other CPU's racing
on the fields.
Also, fix x86 FP state after fork() by making sure the FP is unlazied
_before_ we copy the state information. Otherwise, if a process did a
fork() while holding the FP state lazily in the registers, the child
would incorrectly unlazy bogus state.

Add TASK_UNMAPPED_BASE for v850
|
|
This is the V850 support maintained by Miles Bader at NEC
Again this is just arch and include/asm- files. It matches 2.5.45-uc1 + v850
fixes which is close to what was in my old tree (some clean up done since then)
plus Kconfig
