John David Anglin e8d8fc219f parisc: Ensure volatile space register %sr1 is not clobbered ... I still see the occasional random segv on rp3440. Looking at one of these (a code 15), it appeared the problem must be with the cache handling of anonymous pages. Reviewing this, I noticed that the space register %sr1 might be being clobbered when we flush an anonymous page. Register %sr1 is used for TLB purges in a couple of places. These purges are needed on PA8800 and PA8900 processors to ensure cache consistency of flushed cache lines. The solution here is simply to move the %sr1 load into the TLB lock region needed to ensure that one purge executes at a time on SMP systems. This was already the case for one use. After a few days of operation, I haven't had a random segv on my rp3440.
