2008-08-26powerpc/ps3: Fix ioremap of spu shadow regsMasakazu Mokuno
Fix the ioremap of the spu shadow regs on the PS3. The current PS3 hypervisor requires the spu shadow regs to be mapped with the PTE page protection bits set as read-only (PP=3). This implementation uses the low level __ioremap() to bypass the page protection settings inforced by ioremap_flags() to get the needed PTE bits set for the shadow regs. This fixes a runtime failure on the PS3 introduced by the powerpc ioremap_prot rework of commit a1f242ff460e4b50a045fa237c3c56cce9eabf83 ("powerpc ioremap_prot").

2008-08-25[x86] Clean up MAXSMP Kconfig, and limit NR_CPUS to 512Linus Torvalds
This fixes a regression that was indirectly caused by commit 1184dc2ffe2c8fb9afb766d870850f2c3165ef25 ("x86: modify Kconfig to allow up to 4096 cpus"). Allowing 4k CPU's is not practical at this time, because we still have a number of places that have several 'cpumask_t's on the stack, and a 4k-bit cpumask is 512 bytes of stack-space for each such variable. This literally caused functions like 'smp_call_function_mask' to have a 2.5kB stack frame, and several functions to have 2kB stackframes. With an 8kB stack total, smashing the stack was simply much too likely. At least bugzilla entry http://bugzilla.kernel.org/show_bug.cgi?id=11342 was due to this. The earlier commit to not inline load_module() into sys_init_module() fixed the particular symptoms of this that Alan Brunelle saw in that bugzilla entry, but the huge stack waste by cpumask_t's was the more direct cause. Some day we'll have allocation helpers that allocate large CPU masks dynamically, but in the meantime we simply cannot allow cpumasks this large. Cc: Alan D.

2008-08-25[IA64] Fix ia64 build failure when CONFIG_SFC=mRobin Holt
CONFIG_SFC=m uses topology_core_siblings() which, for ia64, expects cpu_core_map to be exported. It is not. This patch exports the needed symbol. Maintainers note: This really looks like the wrong thing to do ... it would be much better for the kernel to export an API to provide drivers like this with data they need (which in the case of this driver seems to be an estimate of the effective parallelism available on the platform). But x86 has exported this forever ... so go with the flow until such an API is defined.

2008-08-25x86: fix HPET regression in 2.6.26 versus 2.6.25, check hpet against BAR, v3Yinghai Lu
David Witbrodt tracked down (and bisected) a hpet bootup hang on his system to the following problem: a BIOS bug made the hpet device visible as a generic PCI device. If e820 reserved entries happen to be registered first in the resource tree [which v2.6.26 started doing], then the PCI code will reallocate that device's BAR to some other address - breaking timer IRQs and hanging the system. ( Normally hpet devices are hidden by the BIOS from the OS's PCI discovery via chipset magic. Sometimes the hpet is not a PCI device at all. ) Solve this fundamental fragility by making non-PCI platform drivers insert resources into the resource tree even if it overlaps the e820 reserved entry, to keep the resource manager from updating the BAR. Also do these checks for the ioapic and mmconfig addresses, and emit a warning if this happens.

2008-08-23x86 MCE: Fix CPU hotplug problem with multiple multicore AMD CPUsRafael J. Wysocki
During CPU hot-remove the sysfs directory created by threshold_create_bank(), defined in arch/x86/kernel/cpu/mcheck/mce_amd_64.c, has to be removed before its parent directory, created by mce_create_device(), defined in arch/x86/kernel/cpu/mcheck/mce_64.c . Moreover, when the CPU in question is hotplugged again, obviously the latter has to be created before the former. At present, the right ordering is not enforced, because all of these operations are carried out by CPU hotplug notifiers which are not appropriately ordered with respect to each other. This leads to serious problems on systems with two or more multicore AMD CPUs, among other things during suspend and hibernation. Fix the problem by placing threshold bank CPU hotplug callbacks in mce_cpu_callback(), so that they are invoked at the right places, if defined. Additionally, use kobject_del() to remove the sysfs directory associated with the kobject created by kobject_create_and_add() in threshold_create_bank(), to prevent the kernel from crashing during CPU hotplug operations on systems with two or more multicore AMD CPUs.
