CVS commit: src/sys/uvm



Module Name:    src
Committed By:   chs
Date:           Sat Aug  6 05:55:37 UTC 2022

Modified Files:
        src/sys/uvm: uvm_km.c

Log Message:
allow KMSAN to work again by restoring the limiting of kva even with
NKMEMPAGES_MAX_UNLIMITED.  we used to limit kva to 1/8 of physmem
but limiting to 1/4 should be enough, and 1/4 still gives the kernel
enough kva to map all of the RAM that KMSAN has not stolen.
