* [PATCH] create struct compat_timex and use it everywhereStephen Rothwell2006-03-268-119/+38
| | | | | | | | | | | | | | We had a copy of the compatibility version of struct timex in each 64 bit architecture. This patch just creates a global one and replaces all the usages of the old ones.

* [PATCH] VFS,fs/locks.c,NFSD4: add race_free posix_lock_file_conf() interfaceAndy Adamson2006-03-262-8/+25
| | | | | | | | | | | | | | | | | | | | Lockd and the NFSv4 server both exercise a race condition where posix_test_lock() is called either before or after posix_lock_file() to deal with a denied lock request due to a conflicting lock. Remove the race condition for the NFSv4 server by adding a new conflicting lock parameter to __posix_lock_file() , changing the name to __posix_lock_file_conf(). Keep posix_lock_file() interface, add posix_lock_conf() interface, both call __posix_lock_file_conf().

* [PATCH] Use __read_mostly on some hot fs variablesEric Dumazet2006-03-2612-35/+35
| | | | | | | | | | | | | | I discovered on oprofile hunting on a SMP platform that dentry lookups were slowed down because d_hash_mask, d_hash_shift and dentry_hashtable were in a cache line that contained inodes_stat. So each time inodes_stats is changed by a cpu, other cpus have to refill their cache line. This patch moves some variables to the __read_mostly section, in order to avoid false sharing.

* [PATCH] ipmi: add full sysfs supportCorey Minyard2006-03-268-57/+712
| | | | | | | | | | | | | | | | | | | | | | | | Add full driver model support for the IPMI driver. It links in the proper bus and device support. It adds an "ipmi" driver interface that has each BMC discovered by the driver (as a device). These BMCs appear in the devices/platform directory. If there are multiple interfaces to the same BMC, the driver should discover this and will only have one BMC entry. The BMC entry will have pointers to each interface device that connects to it. The device information (statistics and config information) has not yet been ported over to the driver model from proc, that will come later. This work was based on work by Yani Ioannou. I basically rewrote it using that code as a guide, but he still deserves credit :).

* [PATCH] EFI: keep physical table addresses in efi structureBjorn Helgaas2006-03-2612-60/+84
| | | | | | | | | | | | | | | | | | | | | | | | | | | Almost all users of the table addresses from the EFI system table want physical addresses. So rather than doing the pa->va->pa conversion, just keep physical addresses in struct efi. This fixes a DMI bug: the efi structure contained the physical SMBIOS address on x86 but the virtual address on ia64, so dmi_scan_machine() used ioremap() on a virtual address on ia64. This is essentially the same as an earlier patch by Matt Tolentino: http://marc.theaimsgroup.com/?l=linux-kernel&m=112130292316281&w=2 except that this changes all table addresses, not just ACPI addresses. Matt's original patch was backed out because it caused MCAs on HP sx1000 systems. That problem is resolved by the ioremap() attribute checking added for ia64.

| | | | | | | | | | | | | | | | | dmi_scan_machine() tries to ioremap 0x10000 (64K) bytes, even though it only looks at the first 32 bytes or so. If the SMBIOS table is near the end of a memory region, the ioremap() may fail when it shouldn't. This is in the efi_enabled path, so it really only affects ia64 at the moment.

* [PATCH] ia64: use i386 dmi_scan.cMatt Domsch2006-03-266-33/+83
| | | | | | | | | | | | | | | | | | | | | | | | | | | Enable DMI table parsing on ia64. Andi Kleen has a patch in his x86_64 tree which enables the use of i386 dmi_scan.c on x86_64. dmi_scan.c functions are being used by the drivers/char/ipmi/ipmi_si_intf.c driver for autodetecting the ports or memory spaces where the IPMI controllers may be found. This patch adds equivalent changes for ia64 as to what is in the x86_64 tree. In addition, I reworked the DMI detection, such that on EFI-capable systems, it uses the efi.smbios pointer to find the table, rather than brute-force searching from 0xF0000. On non-EFI systems, it continues the brute-force search. My test system, an Intel S870BN4 'Tiger4', aka Dell PowerEdge 7250, with latest BIOS, does not list the IPMI controller in the ACPI namespace, nor does it have an ACPI SPMI table. Also note, currently shipping Dell x8xx EM64T servers don't have these either, so DMI is the only method for obtaining the address of the IPMI controller.

* [PATCH] i386: export: memory more than 4G through /proc/iomemVivek Goyal2006-03-261-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | Currently /proc/iomem exports physical memory also apart from io device memory. But on i386, it truncates any memory more than 4GB. This leads to problems for kexec/kdump. Kexec reads /proc/iomem to determine the system memory layout and prepares a memory map based on that and passes it to the kernel being kexeced. Given the fact that memory more than 4GB has been truncated, new kernel never gets to see and use that memory. Kdump also reads /proc/iomem to determine the physical memory layout of the system and encodes this informaiton in ELF headers. After a crash new kernel parses these ELF headers being used by previous kernel and vmcore is prepared accordingly. As memory more than 4GB has been truncated, kdump never sees that memory and never prepares ELF headers for it. Hence vmcore is truncated and limited to 4GB even if there is more physical memory in the system. This patch exports memory more than 4GB through /proc/iomem on i386.

* [PATCH] protect remove_proc_entrySteven Rostedt2006-03-263-3/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | It has been discovered that the remove_proc_entry has a race in the removing of entries in the proc file system that are siblings. There's no protection around the traversing and removing of elements that belong in the same subdirectory. This subdirectory list is protected in other areas by the BKL. So the BKL was at first used to protect this area too, but unfortunately, remove_proc_entry may be called with spinlocks held. The BKL may schedule, so this was not a solution. The final solution was to add a new global spin lock to protect this list, called proc_subdir_lock. This lock now protects the list in remove_proc_entry, and I also went around looking for other areas that this list is modified and added this protection there too. Care must be taken since these locations call several functions that may also schedule. Since I don't see any location that these functions that modify the subdirectory list are called by interrupts, the irqsave/restore versions of the spin lock was _not_ used.

| * | [ARM] 3030/2: fix permission check in the obscur cmpxchg syscallNicolas Pitre2006-03-251-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch from Nicolas Pitre Quoting RMK: |pte_write() just says that the page _may_ be writable. It doesn't say |that the MMU is programmed to allow writes. If pte_dirty() doesn't |return true, that means that the page is _not_ writable from userspace. |If you write to it from kernel mode (without using put_user) you'll |bypass the MMU read-only protection and may end up writing to a page |owned by two separate processes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Read the processor ID at boot, and save it in "processor_id" as we did before. Later, when we re-parse the CPU type in the setup.c code, re-use the value stored in "processor_id". This allows a cleaner work-around for noMMU devices without CP#15.
