However user SLB misses can # access any kernel memory, which can be used to move some fields out of # the paca (in later patches). # # User SLB misses could quite easily reconcile IRQs and set up a first # class kernel environment and exit via ret_from_except, however that # doesn't seem to be necessary at the moment, so we only do that if a # bad fault is encountered. # # [ Credit to Aneesh for bug fixes, error checks, and improvements to bad # address handling, etc ] # # Signed-off-by: Nicholas Piggin <npiggin@gmail.com> # # Since RFC: # - Added MSR[RI] handling # - Fixed up a register loss bug exposed by irq tracing (Aneesh) # - Reject misses outside the defined kernel regions (Aneesh) # - Added several more sanity checks and error handling (Aneesh), we may # look at consolidating these tests and tightenig up the code but for # a first pass we decided it's better to check carefully. # # Since v1: # - Fixed SLB cache corruption (Aneesh) # - Fixed untidy SLBE allocation "leak" in get_vsid error case # - Now survives some stress testing on real hardware # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-gcc --version # < git log --format=%s --max-count=1
