With sock_loan_thresh=4096, sb_lowat==sb_hiwat, and sowritable will never
be true (even if only a single byte is pending). Some programs (like screen)
expect select() to return that a socket is writable on a socket when there
is space to write to it. XXX: What is the right thing to do here?
Specifically eap but no midi, which makes sense if you want sound,
and umidi but no midi, which makes little sense but shouldn't fail the
build.
Suggest changing the evbarm conf files containing umidi but #midi
to comment out umidi as well (even though this fix should let them build).
make sillyrename (try to) use LINK operation rather than RENAME.
PR/33861 from Jed Davis. he provided the almost same patch.
according to him, it also happen to be what opensolaris does in this case.
from the PR:
> In nfs_rename(), if the destination appears to exist and is "in use"
> (this check is apparently satisfied even if the file isn't in use by
> anything except the rename itself), it will sillyrename it, then delete
> the sillyrenamed file even if the rename fails -- for instance, because
> the "from" file no longer exists on the server.
> mkdir a b; touch a/x; perl -e 'fork(); rename("a/x","b/x") or die "$!\n"'
>
> Afterwards, neither a/x nor b/x will exist.

- generic soft interrupts (ie. use powerpc/softintr.c)
- interrupt event counters (using the ones from powerpc/cpu.h:cpu_info
where appropriate)
- cleanup ibm4xx_intr.h, move implementation details to intr.c
Convert all affected evbppc platforms.

compat kernel to include the GENERIC and use "no" keywords of config(1).
Also merge std.sparc64-64 into std.sparc64 and prepare std.sparc64-32
which uses "no" keywords for 32 bit kernels. OK'ed by mrg.
for a magical PCI device location (that is sometimes wrong), we scan the
residual data for an MPIC, and if we find one, wire it up from there.
This will hopefully allow interrupts to work on the MPC750 and the
7025-F40. I suspect however the interrupt vector address on the 7025 will
still need some work.
syscalls (like mmap), and the same is true for return values (lseek).
Make both structs a union to force alignment. Thanks to uwe for helping
analyze this!
While there move the non syscall-related functions out of this file
(back to trap.c).
This makes kernels compiled with gcc4 and -Os work.
