Vineet Gupta 75370ad440 ARCv2: entry: simplify return to Delay Slot via interrupt ... Commit 4255b07f2c ("ARCv2: STAR 9000793984: Handle return from intr to Delay Slot") involved a complex 2 staged trampoline. Apparently this can be greatly simplified by returning from pure kernel mode (iso interrupt) so drop to pure kernel mdoe and execute the normal exception return path. Testing this was a bit of challenge as return from interrupt is rarely executed now after commit 4de0e52867 ("ARCv2: STAR 9000814690: Really Re-enable interrupts to avoid deadlocks"). That fix is necessary evil and pct interrupts etc do exercise intr return path. Anyhow after a revert of above in my local test setup I was able to hit this case and verify the patch works.
