Recent Vaios (C, AR, N, FE) need some special initialization sequence to enable Fn keys interrupts through the Embedded Controller. Moreover Fn keys have to be decoded internally using ACPI methods to get the key code. Thus a new DMI table to add SNC init time callbacks and new mappings for model-specific key code to generic sony-laptop code have been added. Signed-off-by:

This patch introduces struct pci_sysdata to x86 and x86-64, and converts the existing two users (NUMA, Calgary) to use it. This lays the groundwork for having other users of sysdata, such as the PCI domains work. The Calgary bits are tested, the NUMA bits just look ok. Signed-off-by:

Dead or misnamed CONFIG_BALANCED_IRQ_DEBUG found by Robert P. J. Day. It's not a Kconfig variable. Since this debug code is ancient, I suggest to get rid of this misleading CONFIG_ macro by deleting all of this debug code. Signed-off-by:

Insert HPET resources after pci probing has been completed in order to avoid resource conflicts with PCI resource reservation. With this change the HPET firmware resources will be identified, but it should also not cause issues when the HPET address falls on a BAR in a PCI device, and the PCI enumeration cannot reserve the resources.

This builds upon the existing geode infrastructure, but adds southbridge support, some GPIO functions, and a header file (asm-i386/geode.h) with some useful GX/LX detection tests. The majority of this code was written by Jordan Crouse. Signed-off-by:

get_vm_area always returns an area with an adjacent guard page. That guard page is included in vm_struct.size. iounmap uses vm_struct.size to determine how much address space needs to have change_page_attr applied to it, which will BUG if applied to the guard page. This patch adds a helper function - get_vm_area_size() in linux/vmalloc.h - to return the actual size of a vm area, and uses it to make iounmap do the right thing. There are probably other places which should be using get_vm_area_size(). Thanks to Dave Young <hidave.darkstar@gmail.com> for debugging the problem. [ Andi, it wasn't clear to me whether x86_64 needs the same fix. ] Signed-off-by:

When NUMA emulation succeeds, acpi_numa needs to be set to -1 so that srat_disabled() will always return true. We won't be calling acpi_scan_nodes() or registering the true nodes we've found. [hugh@veritas.com: Fix x86_64 CONFIG_NUMA_EMU build: acpi_numa needs CONFIG_ACPI_NUMA] Signed-off-by:

e820_hole_size() now uses the newly extracted helper function, e820_find_active_region(), to determine the size of usable RAM in a range of PFN's. This was previously broken because of two reasons: - The start and end PFN's of each e820 entry were not properly rounded prior to excluding those entries in the range, and - Entries smaller than a page were not properly excluded from being accumulated. This resulted in emulated nodes being incorrectly mapped to ranges that were completely reserved and not candidates for being registered as active ranges. Signed-off-by:

For K8 system: 4G RAM with memory hole remapping enabled, or more than 4G RAM installed. when using kexec to load second kernel. In the second kernel, when mem is allocated for GART, it will do the memset for clear, it will cause restart, because some device still used that for dma. solution will be: in second kernel: disable that at first before we try to allocate mem for it. or in the first kernel: do disable that before shutdown. Andi/Eric/Alan prefer to second one for clean shutdown in first kernel. Andi also point out need to consider to AGP enable but mem less 4G case too. Signed-off-by:

During a VM oom condition, kill all threads in the process group. We have had complaints where a threaded application is left in a bad state after one of it's threads is killed when we hit a VM: out_of_memory condition. Killing just one of the process threads can leave the application in a bad state, whereas killing the entire process group would allow for the application to restart, or otherwise handled, and makes it very obvious that something has gone wrong. This change allows the entire process group to be taken down, rather than just the one thread. Signed-off-by:

On some systems the ACPI NVS area is located in the first 1 MB of RAM and it is overwritten by the i386 code during the restore after hibernation. This confuses the ACPI platform firmware that doesn't update the AC adapter status appropriately as a result (http://bugzilla.kernel.org/show_bug.cgi?id=7995). The solution is to register the reserved memory in the first 1 MB as 'nosave', so that swsusp doesn't touch it during the restore. Also, this has been done on x86_64 for a long time now, so this patch makes the i386 restore code behave like the x86_64 one. [akpm@linux-foundation.org: build fix] Signed-off-by:

The call happens only in an error-condition which may explain why we have not seen it before. The offending function was not used anywhere else - so marked it __cpuexit.
