o Old HD driver fixed
o Geometry fixes for IDE
o UM8886 IDE controllers irq detection fixed
o 3c59x byte counters
o Remove remaining cern_hippi bits
o ext2 fsync update
o isofs fixes
o de4x5 should compile ok now
Differences between 2.2.0pre7 and 2.2.0pre7ac1
o Config help for Apollo and for INITIO scsi
o Large fd arrays (100,000 per process!)
o Console font handling fixes in 512 char mode
o Lance allows compiling as a module
o EEPro100 has byte counters
o Some shaper bug work - still doesnt work in 2.2.0pre
o Symbios 53c416 support
o QlogicFC fibre channel controller support

Yes, it compiles but the changes in asm/string.h make it oops
on first use. (using both gcc and egcs as per RH52 std.)

Ok. de4x5 will just have to stay not compiling with some egcs for 2.2.0,
sorry people.

Indeed. The fix tries to save the early-clobbered value of 'edi' in
another early-clobbered register ('edx') and is clearly wrong.
I suggest making 'strstr' an external function rather than an
inline. As it stands, it leaves no free general purpose registers for
the compiler to work with, so the optimization gain from inlining will
in any case be extremely limited.
Cheers,
Trond

I can't believe it.
It was recently that de4x5 got fixed (wrt egcs) and now we have
problems again. How's that happened?

There was a new patch for asm-i386/string.h proposed in the list
that was changing the last "g" operator with a "b" operator. I've
checked it and seems to work OK with both gcc and egcs...
OTOS I think that it is too a big fuss for such a little issue: strstr
does not seem to be a performance critical function anyway...I have used
the C library version and I have not appreciated any performance loss.
