* make sysctl/kernel/core_pattern and fs/exec.c agree on maximum core filename ↵Dan Aloni2007-05-17

* gpio interface loosens call restrictionsDavid Brownell2007-05-17
| | | | | | | | | | | | | | Loosen gpio_{request,free}() and gpio_direction_{in,out}put() call context restrictions slightly, so a common idiom is no longer an error: board init code setting up spinlock-safe GPIOs before tasking is enabled. The issue was caught by some paranoid code with might_sleep() checks. The legacy platform-specific GPIO interfaces stick to spinlock-safe GPIOs, so this change reflects current implementations and won't break anything.

* Slab allocators: define common size limitationsChristoph Lameter2007-05-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently we have a maze of configuration variables that determine the maximum slab size. Worst of all it seems to vary between SLAB and SLUB. So define a common maximum size for kmalloc. For conveniences sake we use the maximum size ever supported which is 32 MB. We limit the maximum size to a lower limit if MAX_ORDER does not allow such large allocations. For many architectures this patch will have the effect of adding large kmalloc sizes. x86_64 adds 5 new kmalloc sizes. So a small amount of memory will be needed for these caches (contemporary SLAB has dynamically sizeable node and cpu structure so the waste is less than in the past) Most architectures will then be able to allocate object with sizes up to MAX_ORDER. We have had repeated breakage (in fact whenever we doubled the number of supported processors) on IA64 because one or the other struct grew beyond what the slab allocators supported. This will avoid future issues and f.e. avoid fixes for 2k and 4k cpu support. CONFIG_LARGE_ALLOCS is no longer necessary so drop it. It fixes sparc64 with SLAB.

For some reason alpha is building out-of-line copies of kmalloc_slab() into lots of compilation units.

* Slab allocators: Drop support for destructorsChristoph Lameter2007-05-17
| | | | | | | | | | | | | | | | | | | | | There is no user of destructors left. There is no reason why we should keep checking for destructors calls in the slab allocators. The RFC for this patch was discussed at http://marc.info/?l=linux-kernel&m=117882364330705&w=2 Destructors were mainly used for list management which required them to take a spinlock. Taking a spinlock in a destructor is a bit risky since the slab allocators may run the destructors anytime they decide a slab is no longer needed. Patch drops destructor support. Any attempt to use a destructor will BUG().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Device might be resized during ata_dev_configure() due to HPA or (later) ACPI _GTF. Currently it's worked around by caching n_sectors before turning off HPA. The cached original size is overwritten if the device is reconfigured without being hardreset - which always happens after configuring trasnfer mode. If the device gets hardreset for some reason after that, revalidation fails with -ENODEV. This patch makes size checking more robust by moving n_sectors check from ata_dev_reread_id() to ata_dev_revalidate() after the device is fully configured. No matter what happens during configuration, a device must have the same n_sectors after fully configured to be treated as the same device.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Avoid the costly notifier list in the pagefault path and call the kprobes code directly. The same change went into the 2.6.22 cycle for powerpc, 2s390 and sparc64 already. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>

| | |/ | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hypervisor interfaces need to be negotiated in order to use some API calls reliably. So add a small set of interfaces to request API versions and query current settings. This allows us to fix some bugs in the hypervisor console: 1) If we can negotiate API group CORE of at least major 1 minor 1 we can use con_read and con_write which can improve console performance quite a bit. 2) When we do a console write request, we should hold the spinlock around the whole request, not a byte at a time. What would happen is that it's easy for output from different cpus to get mixed with each other. 3) Use consistent udelay() based polling, udelay(1) each loop with a limit of 1000 polls to handle stuck hypervisor console.
