Subject: arm: Mark uninitialized new TLB entries as not valid
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=1fac3a292ad53811fec534d8a3e49cb86a70aeb8;p=gem5.git

arm: Mark uninitialized new TLB entries as not valid

Previously when we initialized the TLB we would allocate a number of
TLB entries which would be marked as valid. As a result the TLB
contained an entry which would be considered a valid entry for the 0
page.
