The code would save and restore some GPRs around the calls to the C lockdep code, however, it tries to be too smart for its own good and restores some of the GPRs from the exception frame (as saved there on exception entry). However, for page faults, we do replace those GPRs with arguments to do_page_fault before we call transfer_to_handler and so restoring from the exception frame is plain wrong in this case. This was fine as long as we didn't touch the interrupt state when taking page fault, but when I started doing it, it would trigger the lockdep calls and the bug. This fixes it by cleaning up that code a bit. It did create a small stack frame for the sake of backtraces, so let's make it a bit bigger and use it to save and restore the stuff we care about.

Due to this commit, there is a mistake in the way in which tsk->[maj|min]_flt counter gets incremented for VM_FAULT_ERROR: If VM_FAULT_ERROR is returned in the fault flags by handle_mm_fault, then either maj_flt or min_flt will get incremented. This is wrong as in the case of a VM_FAULT_ERROR we need to be skip ahead to the error handling code in do_page_fault. Added a check after the call to __do_page_fault() to check for (fault & VM_FAULT_ERROR).

Since the current code does not re-read the VIC_IRQ_STATUS register, this can lead to multiple invocations of the same interrupt handler and spurious interrupts to be reported. This patch changes the VIC interrupt dispatching code to re-read the status register each time, avoiding duplicate invocations of the same handler.

While doing that, it also speeds them up by doing the accesses a word at a time. Finally, the new routines also properly handle the case of hitting the end of the address space, which we have never done correctly before (fs/namei.c has a hack around it for that reason). Despite all these improvements, it actually removes more lines than it adds, due to the de-duplication. Also, we no longer export (or define) the legacy __strncpy_from_user() function (that was defined to not do the user permission checks), since it's not actually used anywhere, and the user address space checks are built in to the new code. Other architecture maintainers have been notified that the old hack in fs/namei.c will be going away in the 3.5 merge window, in case they copied the x86 approach of being a bit cavalier about the end of the address space.

There is exactly one user of irq_virq_count in-tree right now: PS3. Also, irq_virq_count is only useful for the NOMAP mapping. So, instead of having a single global irq_virq_count values, this change drops it entirely and added a max_irq argument to irq_domain_add_nomap(). That makes it a property of an individual nomap irq domain instead of a global system settting.

McKenney" Date: Fri, 13 Apr 2012 03:35:13 +0000 Subject: sparc64: Eliminate obsolete __handle_softirq() function The invocation of softirq is now handled by irq_exit(), so there is no need for sparc64 to invoke it on the trap-return path. In fact, doing so is a bug because if the trap occurred in the idle loop, this invocation can result in lockdep-RCU failures. The problem is that RCU ignores idle CPUs, and the sparc64 trap-return path to the softirq handlers fails to tell RCU that the CPU must be considered non-idle while those handlers are executing. This means that RCU is ignoring any RCU read-side critical sections in those handlers, which in turn means that RCU-protected data can be yanked out from under those read-side critical sections. The shiny new lockdep-RCU ability to detect RCU read-side critical sections that RCU is ignoring located this problem. The fix is straightforward: Make sparc64 stop manually invoking the softirq handlers. Reported-by: Meelis Roos Suggested-by: David Miller Signed-off-by: Paul E.

If cpu0 then decides to schedule something on cpu1 and wait for it to complete, before cpu0 has set cpu1 active, we have a deadlock. Typically it's this CPU frequency transition that happens at this time, so let's just not wait for it to happen, it will happen whenever the CPU eventually comes online instead.

The default state of the ThumbEE Ctrl register (TEECR) allows userspace accesses to the ThumbEE Base Handler register (TEEHBR). This can cause unexpected behaviour when people use ThumbEE on !CONFIG_ARM_THUMBEE kernels, as well as allowing covert communication - eg between userspace tasks running inside chroot jails. This patch sets up TEECR in order to prevent user-space access to TEEHBR when !CONFIG_ARM_THUMBEE. In this case, tasks are sent SIGILL if they try to access TEEHBR.

We know that 'count' is positive in 'long' (that is checked in the caller), so we will truncate 'max' down to something that fits in a signed long, but before we actually do that, that comparison needs to be done in unsigned. Bug introduced in commit 92ae03f2ef99 ("x86: merge 32/64-bit versions of 'strncpy_from_user()' and speed it up"). On x86-64 you can't trigger this, since the user address space is much smaller than 63 bits, and on x86-32 it works in practice, since you would seldom hit the strncpy limits anyway. I had actually tested the corner-cases, I had only tested them on x86-64. Besides, I had only worried about the case of a pointer *close* to the end of the address space, rather than really far away from it ;) This also changes the "we hit the user-specified maximum" to return 'res', for the trivial reason that gcc seems to generate better code that way. 'res' and 'count' are the same in that case, so it really doesn't matter which one we return.
