This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
- excise some unused code (#if 0'd out - don't want to nuke it yet)
- fix problems with "make depend" - some macros were screwing it up
- get rid of some static local variables
There still seems to be a small reentrancy problem somewhere.
1) cut this up into /sys/sys/inflate.h, sys/kern/inflate.c
sys/kern/ingact_gzip.c
2) make a lot more things static
3) make a lot of globals const
4) make some args const
5) first stage of making globals into a struct (not used yet)
The vm_allocate() call which was introduced between revisions 1.4 and
1.5 of imagact_gzip.c broke things. I have backed that out for the time
being. (Davidg: help please)
WARNING: if you have gzip enabled in your kernel, you must now run
config again, as another source file has been added. Otherwise your
kernel compile will fall over.
This is all still WIP. More commits to come.
Suggestions from: phk.
