[microblaze-uclinux] Update

[John Williams <jwilliams@itee.uq.edu.au>]

Hi folks,

A couple of things:

I think I've finally nailed the mystery bug that was causing random 
hangs in the kernel bootup.  A change in the way the current task 
pointer is handled, and a fixed irq entry/exit process appears to have 
fixed the problem.

The requirement for leading underscores has been removed in line with 
modern gcc implementations.

The irq and updated underscore stuff were checked in to the CVS this 
morning.

Native linux build environment: Seemingly endless problems with Cygwin, 
plus reports of a successful build under Linux are leading me ever 
closer to dropping Cygwin altogether.  It is just not suitable for 
building linux kernels, and the pain of trying to force it outweighs any 
benefits I can perceive at this time.

elf2flt / userland binaries: I've got a placeholder elf2flt working, and 
have successfully built the simpleinit process.  Progress is slow but 
steady.

I'm on holidays from tomorrow until Thursday 24th April, and will be 
about as far out of internet/email range as it's possible to be.  So, I 
hope you all have a safe break (if it's a holiday in your part of the 
world) and I'll be back into it after Easter (hopefully under linux!).

Cheers,

John
