- restructure code so that it doesn't try to allocate user-specified
unbound amount of memory.
- don't ignore copyout failure in the case of E2BIG.
- rename vfs_copyinfh to vfs_copyinfh_alloc for consistency.
with any actual 10-bit devices (as I don't have any), but it doesn't seem to
impact 7-bit addressing any. Approved by christos@, briggs@, and thorpej@.
- don't initialize it needlessly.
- fix the poll code the same way the select code was fixed, so that it
computes the remaining time to sleep properly.
in the bus layer and remove from common ath_attach().
Having it in both layers (on some bus architectures)
was causing a double call to ath_stop() on shutdown
which in turn was tickling the bus lockup described
therin on slower machines.
This allows us to convert aucom to just another com attachment, and cleanup
some code in the com_arbus.c.
Additionally, we use a common com_cleanup routine rather than having a
zillion copies of it in the attachment points.
This has been tested on a number architectures, and it has been shown to get
close to comparable performance when COM_REGMAP is defined, and comparable
when it is not defined.
Approved by core@. Fixes PR port-evbmips/32362.
the only convenient way to use the returned value with numerous library
routines which have not been altered to properly use constified char *.
This was found to be necessary when I extended yamon to hold a string
describing a video mode for use with my experimental radeonfb.
Same object code is generated (except in prf.c, where putchar argument
type was changed to int to match the prototype and one instrcution
changes accordingly).
strategy() in ofdev.c was not ANSIified in this sweep, b/c that
changes code generated at call sites!
try to locate it using the residual data. On some machines this doesn't
work, so we fall back to hardcoding it. This should fix isa interrupts
on the 7025-F40, which has the IVR at a different location.
