vm_object.h vm_pageout.c
Log:
Protect all modifications to paging_in_progress with splvm(). The i386
managed to avoid corruption of this variable by luck (the compiler used a
memory read-modify-write instruction which wasn't interruptable) but other
architectures cannot.
With this change, I am now able to 'make buildworld' on the alpha (sfx: the
crowd goes wild...)
