Gcc used to create code to create trampolines (for nested functions) for
m68k without properly flushing the caches, leading to segmentation violations
on 68040/68060 systems.
Fixed by:
- importing the gcc 2.7.2.3 trampoline creation code into arch/m68k/m68k.h
- adding the OS-specific code for this into arch/m68k/netbsd.h
These changes have been reflected in gcc2netbsd.
overflow (always hated that).
replaced "/m" flag with:
/a == show process address info
/n == show normal process info [currently the default]
/w == show process wait/emul info
floating point stuff removed].
the new kprintf replaces the 3 different (and buggy) versions of
printf that were in the kernel before (kprintf, sprintf, and db_printf),
thus reducing duplicated code by 2/3's. this fixes (or adds) several
printf formats. examples:
%#x - previously only supported by db_printf [not printf/sprintf]
%8.8s - printf would print "000chuck" for "chuck" before
%5p - printf would print "0x 1" for value 1 before
XXX: new kprintf still supports several non-standard '%' formats that
are supposed to eventually be removed:
%: - passes an additional format string and argument list recursively
%b - used to decode error registers
%r - int, but print in radix "db_radix" [DDB only]
%z - 'signed hex' [DDB only]
%n - unsigned int, but print in radix "db_radix" [DDB only]
note that DDB's "%n" conflicts with standard "%n" which takes the
number of characters written so far and stores it into the integer
indicated by the "int *" pointer arg. yuck!
while here, add comments for each function explaining what it is
supposed to do.
* step shared libc version to 12.20
* pick up move of com(4), lpt(4) headers from dev/isa to dev/ic
* remove imp.4 (Arpanet 1822) manpage.
For now, leave manpage references to syscalls that are still emulated
in libc dangling.
In ext2fs, an inode is deleted either when mode == 0 or dtime != 0. If
dtime != 0, reset others fields before using the inode, or we could end
up with the wrong v_op in ext2fs_vinit.
While I'm there, kill a unused variable in ext2fs_readwrite
