* [IA64-SGI] Fix SN PTC deadlock recoveryJack Steiner2005-12-061-2/+6
| | | | | | | | | | | The patch that added support for a new platform chipset (shub2) broke PTC deadlock recovery on older versions of the chipset. (PTCs are the SN platform-specific method for doing a global TLB purge). This patch fixes deadlock recovery so that it works on both the old & new chipsets.

* [IA64] Change SET_PERSONALITY to comply with comment in binfmt_elf.c.Robin Holt2005-12-063-4/+4
| | | | | | | | | | | | | | | | | | | | We have a customer application which trips a bug. The problem arises when a driver attempts to call do_munmap on an area which is mapped, but because current->thread.task_size has been set to 0xC0000000, the call to do_munmap fails thinking it is an unmap beyond the user's address space. The comment in fs/binfmt_elf.c in load_elf_library() before the call to SET_PERSONALITY() indicates that task_size must not be changed for the running application until flush_thread, but is for ia64 executing ia32 binaries. This patch moves the setting of task_size from SET_PERSONALITY() to flush_thread() as indicated. The customer application no longer is able to trip the bug.

* [IA64] Limit the maximum NODEDATA_ALIGN() offsetJack Steiner2005-12-061-1/+3
| | | | | | | | | | | | | The per-node data structures are allocated with strided offsets that are a function of the node number. This prevents excessive cache-aliasing from occurring. On systems with a large number of nodes, the strided offset becomes too large. This patch restricts the maximum offset to 32MB. This is far larger than the size of any current L3 cache.

* [IA64-SGI] altix: pci_window fixupJohn Keller2005-12-061-22/+131
| | | | | | | | | | | | | | Altix only patch to add fixup code that sets up pci_controller->window. This code is a temporary fix until ACPI support on Altix is added. Also, corrects the usage of pci_dev->sysdata, which had previously been used to reference platform specific device info, to now point to a pci_controller struct.

I was getting random "OS panic" errors from OpenBIOS for a while, but with current kernel I get them all the time (probably because image became bigger).

This fixes the arch/powerpc code by adding preempt_disable/enable, and also cleans it up a bit by pulling out the code that discards any lazily-switched CPU register state into a new function, rather than having that code repeated in three places.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | break.b always sets cr.iim to 0 and the current code tries to get the break_num by decoding instruction. However, their seems to be a race condition while reading the regs->cr_iip, as on other cpu the break.b at regs->cr_iip might have been replaced with the original instruction as a result of unregister_kprobe() and hence decoding instruction to obtain break_num will result in wrong value in this case. Also includes changes to kprobes.c which now has to handle break number zero. Signed-off-by: Anil S Keshavamurthy <anil.s.keshavamurthy@intel.com> Signed-off-by: Tony Luck <tony.luck@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We must not call TLB maintainence operations with interrupts disabled, otherwise we risk a lockup in the SMP IPI code. This means that consistent_free() can not be called from a context with IRQs disabled. In addition, we must not hold the lock in consistent_free when we call flush_tlb_kernel_range(). However, we must continue to prevent consistent_alloc() from re-using the memory region until we've finished tearing down the mapping and dealing with the TLB. Therefore, leave the vm_region entry in the list, but mark it inactive before dropping the lock and starting the tear-down process. After the mapping has been torn down, re-acquire the lock and remove the entry from the list. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
