We can't safely directly access an compat_alloc_user_space() pointer with the siginfo copy functions. Bounce it through the stack. Noticed by Al Viro using sparse [ This was only added post 2.6.17, not in any released kernel ] Cc: Al Viro <viro@ftp.linux.org.uk> Signed-off-by:

Add it for P4 model 6 - reported to work and have a similar PMU to earlier P4s. Add an p4force=1 module override parameter for future use. We had a discussion about that earlier - it's a trade off between the PMU staying compatible or not. I think the force parameter is a reasonable compromise.

Currently ia32 binaries behave differently with respect to enabling READ_IMPLIES_EXEC. On i386 a binary with the exec_stack flag set is executed with READ_IMPLIES_EXEC enabled as well. The same binary executes without READ_IMPLIES_EXEC on x86-64. This causes binaries that work on i386 to fail on x86-64 which goes somewhat against the whole 32 bit emulation idea. It has been argued that READ_IMPLIES_EXEC should not be enabled at all for binaries that have the exec_stack flag. Which is probably a valid point. However until this is clarified I think x86-64 should behave the same for ia32 binaries as i386. The following patch brings x86-64 in sync with i386 for ia32 binaries. Signed-off-by:

Add an nfs4 operations count array to nfsd_stats structure. The count is incremented in nfsd4_proc_compound() where all the operations are handled by the nfsv4 server.

Disable lockdep debugging in two situations where the integrity of the kernel no longer is guaranteed: when oopsing and when hitting a tainting-condition. The goal is to not get weird lockdep traces that don't make sense or are otherwise undebuggable, to not waste time. Lockdep assumes that the previous state it knows about is valid to operate, which is why lockdep turns itself off after the first violation it reports, after that point it can no longer make that assumption. A kernel oops means that the integrity of the kernel compromised; in addition anything lockdep would report is of lesser importance than the oops. All the tainting conditions are of similar integrity-violating nature and also make debugging/diagnosing more difficult. Signed-off-by:

Currently most architectures either always build binfmt_elf32 in the kernel image or make it a boolean option. Only sparc64 and s390 allow to build it modularly. This patch turns the option into a boolean aswell because elf requires various symbols that shouldn't be available to modules. The most urgent one is tasklist_lock whos export this patch series kills, but there are others like force_sgi aswell. Note that sparc doesn't allow a modular 32bit a.out handler either, and that would be the more useful case as only few people want 32bit sunos compatibility and 99.9% of all sparc64 users need 32bit linux native elf support.

Currently the snsc driver uses force_sig to send init a SIGPWR when the system overheats. This patch switches it to kill_proc instead which has the following advantages: (1) gets rid of one of the last remaining tasklist_lock users in modular code (2) simplifies the snsc code significantly The downside is that an init implementation could in theory block SIGPWR and it would not get delivered. The sysvinit code used by all major distributions doesn't do this and blocking this signal in init would be a rather stupid thing to do. Signed-off-by: -

- Switch from register_chrdev() to (register|alloc)_chrdev_region(). - use a cdev. This was intended for original patchset, but was overlooked. We use a single cdev for all pins (minor device-numbers), as gleaned from cs5535_gpio, and in contrast to whats currently done in scx200_gpio (which I'll fix soon) Signed-off-by:

Fix module-init-func by repairing usage of platform_device_del/put in module-exit-func. IOW, it imitates Ingo's 'mishaps' patch, which fixed the module-init-func's undo handling. Also fixes lack of release_region to undo the earlier registration. Also starts to 'use a cdev' which was originally intended (its present in scx200_gpio). Code compiles and runs, exhibits a lesser error than previously. (re-register-chrdev fails) Since I had to add "include <linux/cdev.h>", I went ahead and made 2 tweaks that fell into diff-context-window: - remove include <linux/config.h> everyone's doing it - copyright updates - current date is 'wrong' Signed-off-by:

Lennert Buytenhek authored
Newer ARMs have a 40 bit physical address space, but mapping physical memory above 4G needs a special page table format which we (currently?) do not use for userspace mappings, so what happens instead is that mapping an address >= 4G will happily discard the upper bits and wrap. There is a valid_mmap_phys_addr_range() arch hook where we could check for >= 4G addresses and deny the mapping, but this hook takes an unsigned long address: static inline int valid_mmap_phys_addr_range(unsigned long addr, size_t size); And drivers/char/mem.c:mmap_mem() calls it like this: static int mmap_mem(struct file * file, struct vm_area_struct * vma) { size_t size = vma->vm_end - vma->vm_start; if (!valid_mmap_phys_addr_range(vma->vm_pgoff << PAGE_SHIFT, size)) So that's not much help either. This patch makes the hook take a pfn instead of a phys address.

When EDAC was first introduced into the kernel it had a sysfs interface, but due to some problems it was disabled in 2.6.16 and remained disabled in 2.6.17. With feedback, several of the control and attribute files of that interface had some good constructive feedback. PCI Blacklist/Whitelist was a major set which has design issues and it has been removed in this patch. Instead of storing PCI broken parity status in EDAC, it has been moved to the pci_dev structure itself by a previous PCI patch. A future patch will enable that feature in EDAC by utilizing the pci_dev info. The sysfs is now enabled in this patch, with a minimal set of control and attribute files for examining EDAC state and for enabling/disabling the memory and PCI operations. The Documentation for EDAC has also been updated to reflect the new state of EDAC operation. Signed-off-by:
