CVS commit: src/sys/arch/mips

["Simon Burge" <simonb%netbsd.org@localhost>]

Module Name:    src
Committed By:   simonb
Date:           Sun Aug 23 10:23:38 UTC 2020

Modified Files:
        src/sys/arch/mips/include: mips_param.h proc.h
        src/sys/arch/mips/mips: mipsX_subr.S vm_machdep.c

Log Message:
Use a 16kB USPACE (and larger kernel stack) for LP64 kernels.  Invert
the logic for setting the USPACE size.  Define a desired USPACE size
(16kB for LP64, 8kB otherwise) then divide by PAGE_SIZE to get UPAGES.

Fixes random segmap lossage, since the uarea usually sits immediately
above the segmap for a process.  Thanks to mrg@, skrll@ and dholland@
for testing, debugging and general help tracking down this problem.
