* [IA64] fsys_getcpu for IA64Fenghua Yu2007-03-082-0/+106
| | | | | | | | | | | | | | | On 1.6GHz Montectio Tiger4, the following performance data is measured with kernel built with defconfig which has NUMA configured: Fastest sys_getcpu: 502 itc counts. Fastest fsys_getcpu: 28 itc counts. fsys_getcpu performance is largly impacted by whether data (node_to_cpu_map etc) is in cache. It can take fsys_getcpu up to ~150 itc counts in cold cache case.

* [IA64] Pick highest possible saved_max_pfn for crash_dumpTony Luck2007-03-081-5/+5
| | | | | | | | | | | Berhhard Walle noted that on his HP rx8640 he ended up with saved_max_pfn smaller than the highest address of system ram in /proc/iomem and proposed a patch to base the address on the unrounded and unfiltered EFI memory map address. Simon Horman and Magnus Damm suggested that the whole test be moved earlier in the function. This is the combination of both of these patches. Signed-off-by: Tony Luck <tony.luck@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(). The kexec-tools-testing code for this can be found here: http://lists.osdl.org/pipermail/fastboot/2007-February/005983.html Signed-off-by: Magnus Damm <magnus@valinux.co.jp> Cc: Simon Horman <horms@verge.net.au> Cc: Vivek Goyal <vgoyal@in.ibm.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Tony Luck <tony.luck@intel.com>
* [IA64] permon use-after-free fixNick Piggin2007-03-061-4/+7
| | | | | | | | | | | | | | | | Perfmon associates vmalloc()ed memory with a file descriptor, and installs a vma mapping that memory. 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 results in use-after-free bugs and multiple freeing of pages, etc. I saw this bug on an Altix on SLES9. Haven't reproduced upstream but it looks like the same issue is there.

| | | | | | | | | | | | | | | | Make saved_max_pfn point to max_pfn of entire system. Without this patch is so that vmcore is zero length on ia64. This is because saved_max_pfn was wrongly being set to the max_pfn of the crash kernel's address space, rather than the max_pfg on the physical memory of the machine - the whole purpose of vmcore is to access physical memory that is not part of the crash kernel's addresss space.

* | [PATCH] sysctl: remove insert_at_head from register_sysctlEric W. Biederman2007-02-143-3/+3

Which is pain for caching and the proc interface never implemented. I have done an audit and discovered that none of the current users of register_sysctl care as (excpet for directories) they do not register duplicate sysctl entries. So this patch simply removes the support for overriding existing entries in the sys_sysctl interface since no one uses it or cares and it makes future enhancments harder. Signed-off-by: Eric W.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By not using the enumeration in sysctl.h (or even understanding it) the SN platform placed their arch specific xpc directory on top of CTL_KERN and only because they didn't have 4 entries in their xpc directory got lucky and didn't break glibc. 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. And now that they have no ABI numbers add them to the end instead of the sysctl list instead of the head so nothing else will be overridden. Cc: Tony Luck <tony.luck@intel.com> Signed-off-by: Eric W.

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.

| * msi: Kill the msi_desc array.Eric W. Biederman2007-02-081-1/+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.

| | * Altix: ACPI SSDT PCI device supportJohn Keller2007-02-034-103/+362
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add SN platform support for running with an ACPI capable PROM that defines PCI devices in SSDT tables. 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.

| | * ACPI_NUMA: fix HP IA64 simulator issue with extended memory domainAlexey Starikovskiy2007-02-031-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ACPI 3.0 incorporated the SRAT spec, upping the table version to 2, and extending the size of the proximity domain from 1-byte to 4-bytes. This extension was into a reserved field that firmware should set to 0, but the HP simulator had non-zero values there resulting in unexpected huge numbers. So mask the domain down to 8-bits for now. A more general fix will be to check the table version supplied by firmware and get paranoid about reserved fields.
