This is a response to an earlier discussion on linux-mm about splitting slab.h components per allocator. Patch is against 2.6.19-git11. See http://marc.theaimsgroup.com/?l=linux-mm&m=116469577431008&w=2 This patch cleans up the slab header definitions. We define the common functions of slob and slab in slab.h and put the extra definitions needed for slab's kmalloc implementations in <linux/slab_def.h>. In order to get a greater set of common functions we add several empty functions to slob.c and also rename slob's kmalloc to __kmalloc. Slob does not need any special definitions since we introduce a fallback case. If there is no need for a slab implementation to provide its own kmalloc mess^H^H^Hacros then we simply fall back to __kmalloc functions. That is sufficient for SLOB. Sort the function in slab.h according to their functionality. First the functions operating on struct kmem_cache * then the kmalloc related functions followed by special debug and fallback definitions. Also redo a lot of comments.

Remove calls to pci_disable_device except in fail_all_cmds. The pci_disable_device function does something nasty to Smart Array controllers that pci_enable_device does not undo. So if the driver is unloaded it cannot be reloaded. Also, customers can disable any pci device via the ROM Based Setup Utility (RBSU). If the customer has disabled the controller we should not try to blindly enable the card from the driver. Please consider this for inclusion. Signed-off-by:

When CONFIG_PCI is not defined (i.e. PCI bus is disabled), the sx driver fails to link, since some pci functions are not available. Fix this behaviour to be able to compile this driver on machines with no PCI bus (but with ISA bus support). Signed-off-by:

The previous checkstack fix for UML, which needs to use the host's tools, was wrong in the crossbuilding case. It would use the build host's, rather than the target's, toolchain. This patch removes the old fix and adds an explicit special case for UML, leaving everyone else alone. Signed-off-by:

Fallback_alloc() does not do the check for GFP_WAIT as done in cache_grow(). Thus interrupts are disabled when we call kmem_getpages() which results in the failure. Duplicate the handling of GFP_WAIT in cache_grow(). Signed-off-by:

Fields of struct pipe_buf_operations have not a precise layout (ie not optimized to fit cache lines nor reduce cache line ping pongs) The bufs[] array is *large* and is placed near the beginning of the structure, so all following fields have a large offset. This is unfortunate because many archs have smaller instructions when using small offsets relative to a base register. On x86 for example, 7 bits offsets have smaller instruction lengths. Moving bufs[] at the end of pipe_buf_operations permits all fields to have small offsets, and reduce text size, and icache pressure. # size vmlinux.pre vmlinux text data bss dec hex filename 3268989 664356 492196 4425541 438745 vmlinux.pre 3268765 664356 492196 4425317 438665 vmlinux So this patch reduces text size by 224 bytes on my x86_64 machine. Similar results on ia32. Signed-off-by:Eric Dumazet <dada1@cosmosbay.com> Signed-off-by:

Those two functions are void sym_set_change_count(int count) and void sym_add_change_count(int count) All write accesses to sym_change_count are replaced by calls to above functions. Variable and changer-functions are moved to confdata.c. IMO thats ok, as sym_change_count is an attribute of the .config's change state. Signed-off-by:

Run "make xconfig" on a freshly untarred kernel-tree. Look at the floppy disk icon of the qt application, that has just started: Its in a normal, active state. Mouse click on it: .config is being saved. This patch series changes things so taht after the mouse click on the floppy disk icon, the icon is greyed out. If you mouse click on it now, nothing happens. If you change some CONFIG_*, the floppy disk icon returns to "active state", that is, if you mouse click it now, .config is written. This patch: Returns sym_change_count to reflect the .config's change state. All read only accesses of sym_change_count are replaced by calls to conf_get_changed() . mconfig.c is manipulated to ask for saving only when conf_get_changed() returned true. Signed-off-by:

This reverts commit 373beb35. No one is using this identifier yet. The purpose of this identifier is to export nsproxy to user space which is wrong. nsproxy is an internal implementation optimization, which should keep our fork times from getting slower as we increase the number of global namespaces you don't have to share. Adding a global identifier like this is inappropriate because it makes namespaces inherently non-recursive, greatly limiting what we can do with them in the future. Signed-off-by:

The pcd, pwt, and pat bits on page table entries affect the cpu cache. Since the cache is a host resource, the guest should not be able to control it. Moreover, the meaning of these bits changes depending on whether pat is enabled or not. So, force these bits to zero on shadow page table entries at all times. Signed-off-by:

Eliminate some possibilities for user processes writing to the Gigaset character device to be left sleeping indefinitely, by adding wakeup calls to error paths and properly disposing of pending write requests when the device is disconnected. It also removes unnecessary NULL checks before usb_free_urb() and usb_kill_urb() calls. Signed-off-by:

More fixes to build breakage from the work_struct changes ... this updates the tps65010 driver. Plus, fix some dependencies related to the way it's used on the OMAP OSK: force static linking there, since the resulting kernel can't link. NOTE that until the i2c core gets fixed to work without SMBUS_QUICK, kernels needing this driver must still use "tps65010.force=0,0x48" on the command line. Signed-off-by:
