5ce90889f0 Remove unneeded header file. 1996-06-12 23:40:29 +00:00
cgd
a59ba05045 don't pass "argc," "argv," and "envp" from boot blocks to kernel; 
they're unnecessary and there's no reason to use them.  Have the
kernel get necessary values from the PROM directly.

3b3f71fb25 don't pass the firmware's console environment variable to the various console 
initialization functions any more.  None of them used it, and they can
get the same data more easily via the RPB.

31c4f7d574 Only read beyond the first byte of the podule header if we know that 
an extended header is present i.e. don't assume an extended header as
however unlikely there could be a podule that doesn't have one.
Calculate an absolute address for the podule's interrupt mask rather
than leaving it relative to the base address of the podule.
If the interrupt status pointers are not present or are zero then
used the default bits as specified in the podule specification to
determine if the podule is interrupting.

857439698b Claim the interrupt when leaving the interrupt handler as there can

27ab616466 Don't claim the podule interrupts but pass them on in case of

Fill out the ih_maskaddr and ih_maskbits fields in the interrupt handler

if the handler should be called.
General code tidy up and source code formatting.

eef7b263f1 remove GENERIC_NFS, because:
