2001-06-23Sync with NetBSD 19990911 (just before PMAP_NEW was required)smart
- thread_sleep_msg() -> uvm_sleep() - initialize reference count lock in uvm_anon_{init,add}() - add uao_flush() - replace boolean 'islocked' with 'lockflags' - in uvm_fault() change FALSE to TRUE to in 'wide' fault handling - get rid of uvm_km_get() - various bug fixes
2001-03-22Sync style, typo, and comments a little closer to NetBSD. art@ oksmart
2001-03-08Replace thread_wakeup() with wakeup(). It is defined in vm_extern.h as asmart
wrapper, so this removes a dependence on the old VM system. From NetBSD. art@ ok

2000-09-07Convert bzero to memset(X, 0..) and bcopy to memcpy.Artur Grabowski
This is to match (make diffs smaller) the code in NetBSD. new gcc inlines those functions, so this could also be a performance win.
2000-03-16Bring in some new UVM code from NetBSD (not current).Artur Grabowski
- Introduce a new type of map that are interrupt safe and never allow faults in them. mb_map and kmem_map are made intrsafe. - Add "access protection" to uvm_vslock (to be passed down to uvm_fault and later to pmap_enter). - madvise(2) now works. - various cleanups.
1999-09-03Change the pmap_enter api to pass down an argument that indicatesArtur Grabowski
the access type that caused this mapping. This is to simplify pmaps with mod/ref emulation (none for the moment) and in some cases speed up pmap_is_{referenced,modified}. At the same time, clean up some mappings that had too high protection. XXX - the access type is incorrect in old vm, it's only used by uvm and MD code. The actual use of this in pmap_enter implementations is not in this commit.
1999-08-23sync with NetBSD from 1999.05.24 (there is a reason for this date)Artur Grabowski
Mostly cleanups, but also a few improvements to pagedaemon for better handling of low memory and/or low swap conditions.
