Alan Cox	47b8bc92e8	Commit the correct patch, i.e., the one that actually corresponds ... to the rev 1.2 log entry.	1999-07-13 06:35:25 +00:00
Alan Cox	e58bb1c453	Changed the implementation of the primitives to guarantee atomicity ... with respect to interrupts on UP systems. (The upgrade from gcc 2.7.x to egcs 1.1.2 produced at least one non-atomic code sequence in swap_pager_getpages.) In addition, the primitives are now SMP-safe, but only on SMPs. (For portability between SMPs and UPs, modules are compiled with the SMP-safe versions.) Submitted by: dillon and myself Reviewed by: bde	1999-07-13 03:32:17 +00:00
Doug Rabson	069e9bc1b4	Change various syscalls to use size_t arguments instead of u_int. ... Add some overflow checks to read/write (from bde). Change all modifications to vm_page::flags, vm_page::busy, vm_object::flags and vm_object::paging_in_progress to use operations which are not interruptable.
