When udelay() gets called with a delay that would expire before the next clock event it reprograms the clock comparator. When the interrupt happens the clock comparator won't be resetted therefore the interrupt condition doesn't get cleared. The result is an endless timer interrupt loop until the next clock event would expire (stored in lowcore). So udelay() usually would wait much longer for small delays than it should. Fix this by disabling the local tick which makes sure that the clock comparator will be resetted when a timer interrupt happens.

The s390 version of module_frob_arch_sections allocates additional syminfos for got and plt offsets. These syminfos are freed on sucessful module load. If the module fails to load (e.g. missing dependency when using insmod instead of modprobe) this area is not freed. This patch lets module_free free this area. Please note, we have to set the pointer to NULL since module_free is called several times from the generic code.

When using mmu notifiers, we are allowed to remove the page count reference tooken by get_user_pages to a specific page that is mapped inside the shadow page tables. This is needed so we can balance the pagecount against mapcount checking. (Right now kvm increase the pagecount and does not increase the mapcount when mapping page into shadow page table entry, so when comparing pagecount against mapcount, you have no reliable result.)

This patch fixes the m32r SMP kernel after 2.6.27. A part of the following patch breaks m32r SMP operation. > m32r: convert to generic helpers for IPI function calls > commit 7b7426c8 In the above patch, a CALL_FUNC_SINGLE_IPI was newly introduced, but the its IPI vector number was wrong in the patch code. The m32r SMP kernel hanged-up during boot operation, because the CPU_BOOT_IPI was called instead of CALL_FUNC_SINGLE_IPI (CPU_BOOT_IPI had no side effect at that time because the 2nd core had already been started up), as a result, csd_unlock() was not called, then a dead lock occurred in csd_lock_wait() after the detection of Compact Flash memory as IDE generic disk.

Currently, on ARMv6 and ARMv7, if an application tries to execute code (or garbage) on non-executable page it hangs. It caused by incorrect prefetch abort handling. Now every prefetch abort processes as a translation fault. To fix this we have to analyze instruction fault status register to figure out reason why we've got the abort and process it accordingly. To make IFSR different from DFSR we set bit 31 which is reserved in both IFSR and DFSR. This patch also tries to protect from future hangs on unexpected exceptions. An application will be killed if unexpected exception type was received. Signed-off-by: NKirill A. Shutemov <kirill@shutemov.name> Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

Instruction fault status register, IFSR, was introduced on ARMv6 to provide status information about the last insturction fault. It needed for proper prefetch abort handling. Now we have three prefetch abort model: * legacy - for CPUs before ARMv6. They doesn't provide neither IFSR nor IFAR. We simulate IFSR with section translation fault status for them to generalize code; * ARMv6 - provides IFSR, but not IFAR; * ARMv7 - provides both IFSR and IFAR. Signed-off-by: NKirill A.
