All consumers of the driver MPC10x, MPC52xx, MPC824x, MPC83xx, and MPC85xx are all using platform devices. We can get ride of the dead code to support using this driver with the old OCP based model Signed-off-by:

Support for the OCP device model on Freescale (FSL) PPC's is no longer used. All FSL PPC's that were using OCP have be converted to using the platform device model. Signed-off-by:

The e200 core is a Book-E core (similar to e500) that has a unified L1 cache and is not cache coherent on the bus. The e200 core also adds a separate exception level for debug exceptions. Part of this patch helps to cleanup a few cases that are true for all Freescale Book-E parts, not just e500. Signed-off-by:

Ensure that the returned pointer from ppc_sys_get_pdata is not NULL before we start using it. This handles any cases where we have variants of processors on the same board with different functionality. Signed-off-by:

This patch,based on sample code by Roland McGrath, adds an execheap permission check that controls the ability to make the heap executable so that this can be prevented in almost all cases (the X server is presently an exception, but this will hopefully be resolved in the future) so that even programs with execmem permission will need to have the anonymous memory mapped in order to make it executable. The only reason that we use a permission check for such restriction (vs. making it unconditional) is that the X module loader presently needs it; it could possibly be made unconditional in the future when X is changed. The policy patch for the execheap permission is available at: http://pearls.tuxedo-es.org/patches/selinux/policy-execheap.patchSigned-off-by:

This patch adds an execstack permission check that controls the ability to make the main process stack executable so that attempts to make the stack executable can still be prevented even if the process is allowed the existing execmem permission in order to e.g. perform runtime code generation. Note that this does not yet address thread stacks. Note also that unlike the execmem check, the execstack check is only applied on mprotect calls, not mmap calls, as the current security_file_mmap hook is not passed the necessary information presently. The original author of the code that makes the distinction of the stack region, is Ingo Molnar, who wrote it within his patch for /proc/<pid>/maps markers. (http://marc.theaimsgroup.com/?l=linux-kernel&m=110719881508591&w=2) The patches also can be found at: http://pearls.tuxedo-es.org/patches/selinux/policy-execstack.patch http://pearls.tuxedo-es.org/patches/selinux/kernel-execstack.patch policy-execstack.patch is the patch that needs to be applied to the policy in order to support the execstack permission and exclude it from general_domain_access within macros/core_macros.te. kernel-execstack.patch adds such permission to the SELinux code within the kernel and adds the proper permission check to the selinux_file_mprotect() hook.

Out-of-tree user of remap_pfn_range hit kernel BUG at mm/memory.c:1112! It passes an unrounded size to remap_pfn_range, which was okay before 2.6.12, but misses remap_pte_range's new end condition. An audit of all the other ptwalks confirms that this is the only one so exposed. Signed-off-by:

Fix a bug on error handling in the direct I/O function. Currently, if a file is opened with the O_DIRECT|O_SYNC flag, the write() syscall cannot receive the EIO error after an I/O error (SCSI cable is disconnected etc.). Return values of other points that call generic_osync_inode() are treated appropriately. Signed-off-by:

I8K: Change to use stock dmi infrastructure instead of homegrown parsing code. The driver now requires box's DMI data to match list of supported models so driver can be safely compiled-in by default without fear of it poking into random SMM BIOS code. DMI checks can be ignored with i8k.ignore_dmi option. Signed-off-by: -

This patch adds support for Dynamic Tick Timer for ARM. Dynamic Tick is also known as VST (Variable Scheduling Timeouts). Dynamic Tick has been in use in the OMAP tree since last October. The patch is not intrusive, and does not do anything unless CONFIG_NO_IDLE_HZ is defined. This patch has the following fixed based on comments from RMK: - Time is updated before calling interrupt handlers. - Added new interrupt flag SA_TIMER to avoid duplicate timer interrupts - Moved struct dyn_tick_timer to time.h until we at some point probably have an arch independent dyn-tick.h - Cleaned up testing for DYN_TICK_ENABLED in irq.c I've cleaned up this patch to fix some remaining issues: - Call the timer tick handler with irqs disabled, as it would be from a normal interrupt - if we have a dyn_tick, we better implement all methods. - generic timer_dyn_reprogram() call, to be called before sleeping - added command line option - "dyntick=" to allow boot-time control of this feature -- rmk Signed-off-by: Tony Lindgren Signed-off-by: -

Patch from Lennert Buytenhek The later ixp2000 models don't need the PCI I/O workaround that we currently perform. Add a config option to disable the workaround, and panic on boot if a kernel without the workaround is booted on a buggy chip. As only pre-production ixp2000s need the workaround, the default is for it not to be configured in. Signed-off-by:

That's the part that keeps track of the ELCR register, and we want to make sure that the PCI interrupts are properly marked level/low.

Patch from Lennert Buytenhek The ixp2000 gpio cleanup broke the ixdp2800 build as it moved some gpio-related functions from arch/platform.h to arch/gpio.h and the ixdp2x00 support code used those functions but didn't include the latter header file. Signed-off-by:

1. Move tp->irq_sync = 0 to before the interrupt mailbox IO in tg3_enable_ints() so that the interrupt handler will always see irq_sync == 0 when interrupts are enabled. 2. Remove the tg3_enable_ints() call in tg3_reset_hw(). Interrupts are always enabled explicitly or through tg3_netif_start(). This is to prevent interrupts being enabled while poll is disabled. 3. Update trans_start with jiffies in tg3_netif_stop() to prevent false NETDEV WATCHDOG. 4. Pass in the proper irq_sync parameter to tg3_full_lock() depending on netif_running() in some of the ethtool set calls. Signed-off-by:

Move all driver spinlocks to be taken at sw IRQ context only. This fixes the skb_copy() we were doing with hw IRQs disabled (which is illegal and triggers a BUG() with HIGHMEM enabled). It also simplifies the locking all over the driver tremendously. We accomplish this feat by creating a special sequence to synchronize with the hw IRQ handler using a binary state and synchronize_irq(). This idea is from Herbert Xu. Thanks to Michael Chan for helping to track down all of the race conditions in initial versions of this code. Signed-off-by: -

There must be a rmb() between reading the status block tag and calling tg3_has_work(). This was missing in tg3_mis() and tg3_interrupt_tagged(). tg3_poll() got it right. Also, SD_STATUS_UPDATED must be cleared in the status block right before we call tg3_has_work(). Only tg3_poll() got this wrong.
