- Special consideration for IA64: Add the ability to specify arch specific per cpu flags - remove .data.percpu attribute from DEFINE_PER_CPU for non-smp case. The arch definitions are all the same. So move them into linux/percpu.h. We cannot move DECLARE_PER_CPU since some include files just include asm/percpu.h to avoid include recursion problems.

This patch extends the Ebony and Walnut platform code to instantiate the existing ds1742 RTC class driver for the DS1743 RTC/NVRAM chip found on both those boards. The patch uses a helper function to scan the device tree and instantiate the appropriate platform_device based on it, so it should be easy to extend for other boards which have mmio mapped RTC chips. Along with this, the device tree binding for the ds1743 chips is tweaked, based on the existing DS1385 OF binding found at: http://playground.sun.com/1275/proposals/Closed/Remanded/Accepted/346-it.txt Although that document covers the NVRAM portion of the chip, whereas here we're interested in the RTC portion, so it's not entirely clear if that's a good model. This implements only RTC class driver support - that is /dev/rtc0, not /dev/rtc, and the low-level get/set time callbacks remain unimplemented. That means in order to get at the clock you will either need a modified version of hwclock which will look at /dev/rtc0, or you'll need to configure udev to symlink rtc0 to rtc.

This adds hooks into the default_machine_crash_shutdown so drivers can register a function to be run in the first kernel before we hand off to the second kernel. This should only be used in exceptional circumstances, like where the device can't be reset in the second kernel alone (as is the case with eHEA). To emphasize this, the number of handles allowed to be registered is currently #def to 1. This uses the setjmp/longjmp code around the call out to the registered hooks, so any bogus exceptions we encounter will hopefully be recoverable. Tested with bogus data and instruction exceptions.

There were several issues if a memreserve range existed and happened to be in highmem: * The bootmem allocator is only aware of lowmem so calling reserve_bootmem with a highmem address would cause a BUG_ON * All highmem pages were provided to the buddy allocator Added a lmb_is_reserved() api that we now use to determine if a highem page should continue to be PageReserved or provided to the buddy allocator. Also, we incorrectly reported the amount of pages reserved since all highmem pages are initally marked reserved and we clear the PageReserved flag as we "free" up the highmem pages.

Using 64k pages on 64-bit PowerPC systems makes life difficult for emulators that are trying to emulate an ISA, such as x86, which use a smaller page size, since the emulator can no longer use the MMU and the normal system calls for controlling page protections. Of course, the emulator can emulate the MMU by checking and possibly remapping the address for each memory access in software, but that is pretty slow. This provides a facility for such programs to control the access permissions on individual 4k sub-pages of 64k pages. The idea is that the emulator supplies an array of protection masks to apply to a specified range of virtual addresses. These masks are applied at the level where hardware PTEs are inserted into the hardware page table based on the Linux PTEs, so the Linux PTEs are not affected. Note that this new mechanism does not allow any access that would otherwise be prohibited; it can only prohibit accesses that would otherwise be allowed. This new facility is only available on 64-bit PowerPC and only when the kernel is configured for 64k pages. The masks are supplied using a new subpage_prot system call, which takes a starting virtual address and length, and a pointer to an array of protection masks in memory. The array has a 32-bit word per 64k page to be protected; each 32-bit word consists of 16 2-bit fields, for which 0 allows any access (that is otherwise allowed), 1 prevents write accesses, and 2 or 3 prevent any access. Implicit in this is that the regions of the address space that are protected are switched to use 4k hardware pages rather than 64k hardware pages (on machines with hardware 64k page support). In fact the whole process is switched to use 4k hardware pages when the subpage_prot system call is used, but this could be improved in future to switch only the affected segments. The subpage protection bits are stored in a 3 level tree akin to the page table tree. The top level of this tree is stored in a structure that is appended to the top level of the page table tree, i.e., the pgd array. Since it will often only be 32-bit addresses (below 4GB) that are protected, the pointers to the first four bottom level pages are also stored in this structure (each bottom level page contains the protection bits for 1GB of address space), so the protection bits for addresses below 4GB can be accessed with one fewer loads than those for higher addresses.

xlate_iomm_address() really wants the ds_addr to pass to the HV, so store that value (instead of the BAR number) when we allocate the device bars. This is not a fast path, so we can look up the device_node property there instead of using the bussubno field of the pci_dn. The other user of iseries_ds_addr() was already scanning the device tree, so looking up a property will not slow it down any more.
