* [SK_BUFF]: Convert skb->tail to sk_buff_data_tArnaldo Carvalho de Melo2007-04-261-5/+5
| | | | | | | | | | | | | | | So that it is also an offset from skb->head, reduces its size from 8 to 4 bytes on 64bit architectures, allowing us to combine the 4 bytes hole left by the layer headers conversion, reducing struct sk_buff size to 256 bytes, i.e. 4 64byte cachelines, and since the sk_buff slab cache is SLAB_HWCACHE_ALIGN... :-) Many calculations that previously required that skb->{transport,network, mac}_header be first converted to a pointer now can be done directly, being meaningful as offsets or pointers.

* [IA64] bugfix stack layout upside-downKAMEZAWA Hiroyuki2007-03-301-1/+1
| | | | | | | | | | | | | | | | | | | | | | | ia64 expects following vm layout: == low memory [register-stack grows up] [memory-stack grows down] == high memory But the code assigns the base of the register stack at the maximum stack size offset from the fixed address where the stack *might* start. Stack randomization will result in the memory stack starting at a lower address than this, and if the user has set a low stack limit with "ulimit -s", then you can end up with the register stack above the memory stack (or if you were very unlucky right on top of it!). Fix: Calculate the base address for the register stack starting from the actual address of the memory stack.

* [PATCH] MSI-X: fix resume crashEric W. Biederman2007-03-281-2/+6
| | | | | | | | | | | | | | So I think the right solution is to simply make pci_enable_device just flip enable bits and move the rest of the work someplace else. However a thorough cleanup is a little extreme for this point in the release cycle, so I think a quick hack that makes the code not stomp the irq when msi irq's are enabled should be the first fix.

* | [IA64] min_low_pfn and max_low_pfn calculation fixZou Nan hai2007-03-203-27/+23
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have seen bad_pte_print when testing crashdump on an SN machine in recent 2.6.20 kernel. There are tons of bad pte print (pfn < max_low_pfn) reports when the crash kernel boots up, all those reported bad pages are inside initmem range; That is because if the crash kernel code and data happens to be at the beginning of the 1st node. build_node_maps in discontig.c will bypass reserved regions with filter_rsvd_memory. Since min_low_pfn is calculated in build_node_map, so in this case, min_low_pfn will be greater than kernel code and data. Because pages inside initmem are freed and reused later, we saw pfn_valid check fail on those pages. I think this theoretically happen on a normal kernel. When I check min_low_pfn and max_low_pfn calculation in contig.c and discontig.c. I found more issues than this. 1. min_low_pfn and max_low_pfn calculation is inconsistent between contig.c and discontig.c, min_low_pfn is calculated as the first page number of boot memmap in contig.c (Why? Though this may work at the most of the time, I don't think it is the right logic). It is calculated as the lowest physical memory page number bypass reserved regions in discontig.c. max_low_pfn is calculated include reserved regions in contig.c. It is calculated exclude reserved regions in discontig.c. 2. If kernel code and data region is happen to be at the begin or the end of physical memory, when min_low_pfn and max_low_pfn calculation is bypassed kernel code and data, pages in initmem will report bad. 3. initrd is also in reserved regions, if it is at the begin or at the end of physical memory, kernel will refuse to reuse the memory. Because the virt_addr_valid check in free_initrd_mem. So it is better to fix and clean up those issues. Calculate min_low_pfn and max_low_pfn in a consistent way.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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().

* | [PATCH] irq: Remove set_native_irq_infoEric W. Biederman2007-02-262-2/+2
|/ | | | | | | | | | This patch replaces all instances of "set_native_irq_info(irq, mask)" with "irq_desc[irq].affinity = mask". The latter form is clearer uses fewer abstractions, and makes access to this field uniform accross different architectures. Signed-off-by: Eric W.

| | | | | | | | | | | | | | | | | | | | | | If an ATA drive uses legacy mode, ata driver will choose 14 and 15 as the fixed irq number. On ia64 platform, such numbers are GSI and should be converted to irq vector. Below patch against kernel 2.6.20 fixes it.

* | [PATCH] sysctl: remove insert_at_head from register_sysctlEric W. Biederman2007-02-143-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The semantic effect of insert_at_head is that it would allow new registered sysctl entries to override existing sysctl entries of the same name. 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.

* | [PATCH] sysctl: C99 convert arch/ia64/kernel/perfmon and remove ABI breakageEric W. Biederman2007-02-141-9/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This convters the sysctl ctl_tables to use C99 initializers. While I was looking at it I discovered it was using a portion of the sysctl binary addresses space under CTL_KERN KERN_OSTYPE which was completely inappropriate. So I completely removed all of the sysctl binary names, to remove and avoid the ABI conflict. Signed-off-by: Eric W.
