Although there's no kernel support for the Java hardware yet, we need to be able to recover from this situation and keep the system running. This patch adds code to detect and fixup this situation in the critical exception handler and terminate the faulting process. We may have to rethink how to handle this more gracefully when the necessary kernel support for hardware-accelerated Java is added.

A side-effect of this is that the decision is now made once for each contiguous section in the LMB array rather than for each page individually. This can often mean that the whole of the linear mapping ends up being executable. This reverts to the previous behaviour, where individual pages are checked for being part of the kernel text or not, by moving the check back down into htab_bolt_mapping.

This patch fixes a problem within the SH implementation of resume_kernel code, that implements in assembly the bulk of preempt_schedule_irq function without taking care of the extra code needed to handle the BKL preemptible. The patch basically consists of removing this asm code and calling the common C implementation (see kernel/sched.c) as other archs do. Another change is the missing 'cli' macro invocation at the beginning of the resume_kernel.

Set it to 5us which seems to be a reasonable value and fixes the problems on the bug reporters machines.

In particular, it doesn't contain the code for CPU feature words 2 (Transmeta), 3 (Linux-specific), 5 (VIA), or 7 (scattered). Zero them out, so we can still set those bits as known at compile time; in particular, this allows creating a Linux-specific NOPL flag and have it required (and therefore resolvable at compile time) in 64-bit mode.

With patch, the test case, as well as the gdb testsuite, pass without incident, padding area reads returning zero, writes ignored. Nb: original version returned -EINVAL on write attempts, which broke the gdb test and made the test case slightly unhappy, Jan Kratochvil suggested the change to return 0 on write attempts.

However, the current way its coded doesn't work on parisc64. For two reasons: 1) parisc isn't in the #ifdef and 2) parisc has a different format for function descriptors Make dereference_function_descriptor() more accommodating by allowing architecture overrides. I put the three overrides (for parisc64, ppc64 and ia64) in arch/kernel/module.c because that's where the kernel internal linker which knows how to deal with function descriptors sits.
