CVS commit: src/sys/arch/i386/i386
Module Name: src
Committed By: jym
Date: Mon May 7 02:32:09 UTC 2012
Use pmap_pte_*bits macros to set/clear bits in a PTE. Remove pmap_pte_flush
calls as these operations are synchronously flushed under Xen; they should
not be cached.
XXX the code can be shared between i386 and amd64, but I will merge
them once I figure out why db_write_text() can cause page faults for
certain CPUs in long mode (code looks correct, but single stepping or
adding debug printf's makes the bug magically disappear... sigh)
Bug reported by David Laight on port-amd64@ when attempting to set
breakpoints through ddb(4).
