* [PATCH] Fix wrong /proc/iomem on SGI AltixBernhard Walle2007-03-181-2/+10
| | | | | | | | | | | | | | | | | | In sn_io_slot_fixup(), the parent is re-set from the bus to io(port|mem)_resource because the address is changed in a way that it's not child of the bus any more. However, only the root is set but not the parent/child/sibling relationship in the resource tree which causes 'cat /proc/iomem' to stop after this memory area. Depding on the poition in the tree the iomem may be nearly completely empty.

See discussion: http://www.gelato.unsw.edu.au/archives/linux-ia64/0307/6108.html The current TLB recovery code is recovering from the duplicate itr.d dropins, masking the underlying problem.

| * ACPI: Altix: reinitialize acpi tablesJohn Keller2007-03-011-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To provide compatibilty with SN kernels that do and do not have ACPI IO support, the SN PROM must build different versions of some ACPI tables based on which kernel is booting. As such, the tables may have to change at kernel boot time. By default, prior to kernel boot, the PROM builds an empty DSDT (header only) and no SSDTs. If an ACPI capable kernel boots, the kernel will notify the PROM, at platform setup time, and the PROM will build full DSDT and SSDT tables. With the latest changes to acpi_table_init(), the table lengths are saved, and when our PROM changes them, the changes are not seen, and the kernel will crash on boot. Because of issues with kexec support, we are not able to create the tables prior to acpi_table_init(). As a result, we are making a second call to acpi_table_init() to process the rebuilt DSDT and SSDTs. Signed-off-by: John Keller <jpk@sgi.com> Signed-off-by: Len Brown <len.brown@intel.com>

* | [IA64] kexec: Use EFI_LOADER_DATA for ELF core headerMagnus Damm2007-03-062-0/+60
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The address where the ELF core header is stored is passed to the secondary kernel as a kernel command line option. The memory area for this header is also marked as a separate EFI memory descriptor on ia64. The separate EFI memory descriptor is at the moment of the type EFI_UNUSABLE_MEMORY. With such a type the secondary kernel skips over the entire memory granule (config option, 16M or 64M) when detecting memory. If we are lucky we will just lose some memory, but if we happen to have data in the same granule (such as an initramfs image), then this data will never get mapped and the kernel bombs out when trying to access it. So this is an attempt to fix this by changing the EFI memory descriptor type into EFI_LOADER_DATA. This type is the same type used for the kernel data and for initramfs. In the secondary kernel we then handle the ELF core header data the same way as we handle the initramfs image. This patch contains the kernel changes to make this happen. Pretty straightforward, we reserve the area in reserve_memory(). The address for the area comes from the kernel command line and the size comes from the specialized EFI parsing function vmcore_find_descriptor_size().

Unfortunately, the vm_file field is not filled in, so processes with mappings to that memory do not prevent the file from being closed and the memory freed.

This is totally irresponsible. So this patch entirely removes sys_sysctl support from their sysctl code. Hopefully they don't have ascii name conflicts as well.

* [PATCH] Common compat_sys_sysinfoKyle McMartin2007-02-112-69/+1
| | | | | | | | | | | | | | | | I noticed that almost all architectures implemented exactly the same sys32_sysinfo... except parisc, where a bug was to be found in handling of the uptime. So let's remove a whole whack of code for fun and profit. Cribbed compat_sys_sysinfo from x86_64's implementation, since I figured it would be the best tested. This patch incorporates Arnd's suggestion of not using set_fs/get_fs, but instead extracting out the common code from sys_sysinfo.

* [PATCH] optional ZONE_DMA: introduce CONFIG_ZONE_DMAChristoph Lameter2007-02-111-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch simply defines CONFIG_ZONE_DMA for all arches. We later do special things with CONFIG_ZONE_DMA after the VM and an arch are prepared to work without ZONE_DMA. CONFIG_ZONE_DMA can be defined in two ways depending on how an architecture handles ISA DMA. First if CONFIG_GENERIC_ISA_DMA is set by the arch then we know that the arch needs ZONE_DMA because ISA DMA devices are supported. We can catch this in mm/Kconfig and do not need to modify arch code. Second, arches may use ZONE_DMA in an unknown way. We set CONFIG_ZONE_DMA for all arches that do not set CONFIG_GENERIC_ISA_DMA in order to insure backwards compatibility. The arches may later undefine ZONE_DMA if their arch code has been verified to not depend on ZONE_DMA.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The arch hooks arch_setup_msi_irq and arch_teardown_msi_irq are now responsible for allocating and freeing the linux irq in addition to setting up the the linux irq to work with the interrupt. arch_setup_msi_irq now takes a pci_device and a msi_desc and returns an irq. With this change in place this code should be useable by all platforms except those that won't let the OS touch the hardware like ppc RTAS. Signed-off-by: Eric W.

| * msi: Kill the msi_desc array.Eric W. Biederman2007-02-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We need to be able to get from an irq number to a struct msi_desc. The msi_desc array in msi.c had several short comings the big one was that it could not be used outside of msi.c. Using irq_data in struct irq_desc almost worked except on some architectures irq_data needs to be used for something else. So this patch adds a msi_desc pointer to irq_desc, adds the appropriate wrappers and changes all of the msi code to use them. The dynamic_irq_init/cleanup code was tweaked to ensure the new field is left in a well defined state. Signed-off-by: Eric W.

There is a SSDT table for every occupied slot on a root bus, containing info for every PPB and/or device on the bus. The SSDTs will be dynamically loaded/unloaded at hotplug enable/disable. Platform specific information that is currently passed via a SAL call, will now be passed via the Vendor resource in the ACPI Device object(s) defined in each SSDT.
