Subject: [PATCH v2 1/3] MIPS: R3000: Fix debug output for Virtual page number
Date: Thu, 30 Oct 2014 22:07:36 +0900 [thread overview]
Message-ID: <1414674458-7583-2-git-send-email-isamu@leafytree.jp> (raw)
In-Reply-To: <1414674458-7583-1-git-send-email-isamu@leafytree.jp>
Virtual page number of R3000 in entryhi is 20 bit from MSB. But in
dump_tlb(), the bit mask to read it from entryhi is 19 bit (0xffffe000).
The patch fixes that to 0xfffff000.
