564ca8fafd Don't bzero() the IO page table; it is fully initialized in iommu_attach(). 1998-05-19 09:17:32 +00:00
pk
9dae8945ef In kvm_uncache(), turn off the PTE cache bit even after calling
pv_changepte(). Reason: the managed() macro does not take into
account the gap in the managed pages range that may have been introduced
by the page table allocation in bootstrap().

e615541de9 Maintain far more complete state in the PV lists on the cacheability of pages,
using separate flag bits for mappings that were requested to be not
cacheable and uncacheable pages due to incongruent aliases.

This avoids inadvertently turning on the cache-enable bits when removing
one of multiple virtual address mappings to the same page. Reading
from /dev/mem could do this to arbitrary pages.

b6933ca39d Reading back the IOMMU registers apparently has the ability to wedge
microSPARC I cpus. Instead insert a couple of no-ops that seems to
avoid the microSPARC II lossage just as well.

b21bfbde11 Add -Wno-main conditional on compiler being gcc 2.8 or egcs. (This adds
a HAVE_GCC28 check-variable that can now be used to add other gcc-2.8
flags in cases where they may be useful, or to remove gcc 2.7.2 "bug
workaround" flags.)
