-false This primary always evaluates to false. This can be used follow-
ing a primary that caused the expression to be true to make the
expression to be false. This can be useful after using a -fprint
primary so it can continue to the next expression (using an -or
operator, for example).
This was brought up on the tech-userlevel list in October.
Using -fprint on findutils or new NetBSD find(1) does not do what
I wanted. For example, if saving results of all files that start
with a vowel or saving results of all files owned by group operator,
then the list of files owned by group operator would not include
the files starting with a vowel.
findutils's find has a workaround for this with -false and also a
"," comma opeator. (I made add this comma operator later; you can use
the comma to perform multiple independent tests.)
i.e. override mips_cache_alias_mask and mips_cache_prefer_mask
with values which match MIPS3_MAX_PCACHE_SIZE (32KB), rather than
leave them actual primary virtual indexed cache size (8KB or 16KB).
Also add comments about what the value means there.
I thought the VCE on R4000/R4400 occurred only if actual virtual alias
was detected because there was an article which mentioned that VCE
detection logic was different according to primary cache size and
it looked reasonable. But all other articles I can find later
(http://www.linux-mips.org/archives/linux-mips/1998-05/msg00084.html etc.)
claimes that VCE detection logic always verifies all 3 bits
between vaddr[14:12] and PIdx[2:0] regardless of primary cache size
(i.e. VCE could occur even if there is no actual virtual alias), and
in fact VCED still happens with the mask values adjusted for 16KB L1
but it doesn't with ones for MIPS3_MAX_PCACHE_SIZE on my R4400 news5000.
- Fix error messages, some are completely incorrect
- Asystem prints the error message so don't bother saving errno
- Don't continue if a lock can't be obtained on /etc/group
- Just pass struct passwd * to removehomedir, not its members
Some copyright maintenance:
- Add Liam Foy.
- Move Todd's copyright higher up.
XXX: We should remove clause 3 and merge the two copyright groups.
- move copyin and friends from locore.S to their own file, copy.S.
share it between i386 and xen.
- defparam KERNBASE and kill KERNBASE_LOCORE hack.
- add more symbols to assym.h and use it where appropriate.
Instead, just add it to the list of files.
Make "prefix foo" lines actually work right when foo is an absolute path,
and make sure the length calculations correspond to the output.
Provide a way to specify a file that will always be included, and a way
to omit the prologue ("$S/") on that file.
instead of setting it to zero. Otherwise nothing ever sets it unless some code
explicitly changes the baud rate. For a serial console (in particular) we want
to use the baud rate set by the bios (or whatever) and used by theboot code.
This is the way it was before a 'new version of com driver' was added in 1997 (rev 1.99)
already-copied pages are paged out. anons that have already been copied
will have refcount == 1, whereas anons that still need to be copied will
have refcount > 1. fixes PR 25392, PR 30257, PR 31924.
"XXX Maxphys temporary changed to 32K while SCSI driver is fixed."
I (and soda) don't know what the "SCSI driver" is, but add local
asc_minphys() to limit max xfer size only for asc.c for now.
- According to old asc.c driver, DMA_START() is called before NCR_CMD_DMA
command. I'm not sure which DMAC or ASC should be started first, but
move DMA command from asc_dma_go() to asc_dma_setup().
- Disable NCR_F_DMASELECT (which allows DMA xfer for select command)
since it caused some problem on PICA.
Now gxemul-0.3.6.2 reaches mountroot() sd0 (but can't exec /sbin/init yet).
