2009-08-18spi_s3c24xx: fix clock rate calculationBen Dooks
Currently the clock rate calculation may round as pleased, which means that it is possible that we will round down and end up with a faster clock rate than intended. Change the calculation to use DIV_ROUND_UP() to ensure that we end up with a clock rate either the same as or lower than the user requested one.

2009-08-18mm: revert "oom: move oom_adj value"KOSAKI Motohiro
The commit 2ff05b2b (oom: move oom_adj value) moveed the oom_adj value to the mm_struct. It was a very good first step for sanitize OOM. However Paul Menage reported the commit makes regression to his job scheduler. Current OOM logic can kill OOM_DISABLED process. Why? His program has the code of similar to the following. ... set_oom_adj(OOM_DISABLE); /* The job scheduler never killed by oom */ ... if (vfork() == 0) { set_oom_adj(0); /* Invoked child can be killed */ execve("foo-bar-cmd"); } .... vfork() parent and child are shared the same mm_struct. then above set_oom_adj(0) doesn't only change oom_adj for vfork() child, it's also change oom_adj for vfork() parent. Then, vfork() parent (job scheduler) lost OOM immune and it was killed. Actually, fork-setting-exec idiom is very frequently used in userland program. We must not break this assumption. Then, this patch revert commit 2ff05b2b and related commit.

In 5e140dfc1fe87eae27846f193086724806b33c7d "net: reorder struct Qdisc for better SMP performance" the definition of struct gnet_stats_basic changed incompatibly, as copies of this struct are shipped to userland via netlink. Restoring old behavior is not welcome, for performance reason. Fix is to use a private structure for kernel, and teach gnet_stats_copy_basic() to convert from kernel to user land, using legacy structure (struct gnet_stats_basic) Based on a report and initial patch from Michael Spang.

2009-08-17inotify: start watch descriptor count at 1Eric Paris
The inotify_add_watch man page specifies that inotify_add_watch() will return a non-negative integer. However, historically the inotify watches started at 1, not at 0. Turns out that the inotifywait program provided by the inotify-tools package doesn't properly handle a 0 watch descriptor. In 7e790dd5 we changed from starting at 1 to starting at 0. This patch starts at 1, just like in previous kernels, but also just like in previous kernels it's possible for it to wrap back to 0.

2009-08-17xfs: fix locking in xfs_iget_cache_hitChristoph Hellwig
The locking in xfs_iget_cache_hit currently has numerous problems: - we clear the reclaim tag without i_flags_lock which protects modifications to it - we call inode_init_always which can sleep with pag_ici_lock held (this is oss.sgi.com BZ #819) - we acquire and drop i_flags_lock a lot and thus provide no consistency between the various flags we set/clear under it This patch fixes all that with a major revamp of the locking in the function. The new version acquires i_flags_lock early and only drops it once we need to call into inode_init_always or before calling xfs_ilock. This patch fixes a bug seen in the wild where we race modifying the reclaim tag.

2009-08-17Security/SELinux: seperate lsm specific mmap_min_addrEric Paris
Currently SELinux enforcement of controls on the ability to map low memory is determined by the mmap_min_addr tunable. This patch causes SELinux to ignore the tunable and instead use a seperate Kconfig option specific to how much space the LSM should protect. The tunable will now only control the need for CAP_SYS_RAWIO and SELinux permissions will always protect the amount of low memory designated by CONFIG_LSM_MMAP_MIN_ADDR. This allows users who need to disable the mmap_min_addr controls (usual reason being they run WINE as a non-root user) to do so and still have SELinux controls preventing confined domains (like a web server) from being able to map some area of low memory.

2009-08-17SELinux: call cap_file_mmap in selinux_file_mmapEric Paris
Currently SELinux does not check CAP_SYS_RAWIO in the file_mmap hook. This means there is no DAC check on the ability to mmap low addresses in the memory space. This function adds the DAC check for CAP_SYS_RAWIO while maintaining the selinux check on mmap_zero. This means that processes which need to mmap low memory will need CAP_SYS_RAWIO and mmap_zero but will NOT need the SELinux sys_rawio capability.

The triggered field of struct poll_wqueues introduced in commit 5f820f648c92a5ecc771a96b3c29aa6e90013bba ("poll: allow f_op->poll to sleep"). It was first set to 1 in pollwake() (now __pollwake() ), tested and later set to 0 in poll_schedule_timeout(), but not initialized before. As a result when the process needs to sleep, triggered was likely to be non-zero even if pollwake() is not called before the first poll_schedule_timeout(), meaning schedule_hrtimeout_range() would not be called and an extra loop calling all ->poll() would be done.

2009-08-15ARM: Fix broken highmem supportRussell King
Currently, highmem is selectable, and you can request an increased vmalloc area. However, none of this has any effect on the memory layout since a patch in the highmem series was accidentally dropped. Moreover, even if you did want highmem, all memory would still be registered as lowmem, possibly resulting in overflow of the available virtual mapping space. The highmem boundary is determined by the highest allowed beginning of the vmalloc area, which depends on its configurable minimum size (see commit 60296c71f6c5063e3c1f1d2619ca0b60940162e7 for details on this). We should create mappings and initialize bootmem only for low memory, while the zone allocator must still be told about highmem. Currently, memory nodes which are completely located in high memory are not supported. This is not a huge limitation since systems relying on highmem support are unlikely to have discontiguous memory with large holes. [ A similar patch was meant to be merged before commit 5f0fbf9ecaf3 and be available in Linux v2.6.30, however some git rebase screw-up of mine dropped the first commit of the series, and that goofage escaped testing somehow as well. -- Nico ] Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> Reviewed-by: Nicolas Pitre <nico@marvell.com>

2009-08-15sh: use in-soc KEYSC on se7724Magnus Damm
This patch updates the Solution Engine 7724 board code to use in-SoC KEYSC resources for the keyboard platform device. Using the in-SoC key scan controller fixes a crash-during-resume issue. Without this patch the KEYSC hardware block located in the board specific FPGA is used together with an external IRQ which is routed through the FPGA and handled by some board specific demux code. This board specific FPGA interrupt code does not implement desc->set_wake() so the enable_irq_wake() call in the sh_keysc driver will fail at suspend-to-ram time and the disable_irq_wake() will bomb out when resuming. Changing the platform data to use the in-SoC KEYSC hardware makes the se7724 board support code less special which is a good thing. Also, the board specific KEYSC pin setup code selects in-SoC pin functions already which makes the current FPGA platform device data look like a typo.

2009-08-14drivers/net: fixed drivers that support netpoll use ndo_start_xmit()Dongdong Deng
The NETPOLL API requires that interrupts remain disabled in netpoll_send_skb(). The use of spin_lock_irq() and spin_unlock_irq() in the NETPOLL API callbacks causes the interrupts to get enabled and can lead to kernel instability. The solution is to use spin_lock_irqsave() and spin_unlock_restore() to prevent the irqs from getting enabled while in netpoll_send_skb(). Call trace: netpoll_send_skb() { -> local_irq_save(flags) ---> dev->ndo_start_xmit(skb, dev) ---> spin_lock_irq() ---> spin_unlock_irq() *******here would enable the interrupt. ... -> local_irq_restore(flags) } Signed-off-by: Dongdong Deng <dongdong.deng@windriver.com> Signed-off-by: Jason Wessel <jason.wessel@windriver.com> Acked-by: Bruce Ashfield <bruce.ashfield@windriver.com> Acked-by: Matt Mackall <mpm@selenic.com> Signed-off-by: David S.
