2010-06-03crypto: pcomp - Fix illegal Kconfig configurationHerbert Xu
The PCOMP Kconfig entry current allows the following combination which is illegal: ZLIB=y PCOMP=y ALGAPI=m ALGAPI2=y MANAGER=m MANAGER2=m This patch fixes this by adding PCOMP2 so that PCOMP can select ALGAPI to propagate the setting to MANAGER2.

2010-06-03padata: add parenthesis in MAX_SEQ_NR macroDan Carpenter
MAX_SEQ_NR is used in padata_alloc_pd() like this: pd->max_seq_nr = (MAX_SEQ_NR / num_cpus) * num_cpus - 1; It needs parenthesis or the divide by num_cpus takes precedence over the subtraction.

2010-05-26crypto: mv_cesa - fixup error handling in mv_probe()Dan Carpenter
The error handling in mv_probe() was a bit messed up. There were some gotos to the wrong labels so it ended up releasing stuff that that hadn't been aquired and not releasing stuff that was meant to be released. I shuffled it around a bit to fix it and make it clearer. Signed-off-by: Dan Carpenter <error27@gmail.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2010-05-25Revert "module: drop the lock while waiting for module to complete ↵Linus Torvalds
initialization." This reverts commit 480b02df3aa9f07d1c7df0cd8be7a5ca73893455, since Rafael reports that it causes occasional kernel paging request faults in load_module(). Dropping the module lock and re-taking it deep in the call-chain is definitely not the right thing to do. That just turns the mutex from a lock into a "random non-locking data structure" that doesn't actually protect what it's supposed to protect. Requested-and-tested-by: Rafael J.

2010-05-26Convert alpha to use clocksources instead of arch_gettimeoffsetJohn Stultz
Alpha has a tsc like rpcc counter that it uses to manage time. This can be converted to an actual clocksource instead of utilizing the arch_gettimeoffset method that is really only there for legacy systems with no continuous counter. Further cleanups could be made if alpha converted to the clockevent model.

2010-05-25driver core: add devname module aliases to allow module on-demand auto-loadingKay Sievers
This adds: alias: devname:<name> to some common kernel modules, which will allow the on-demand loading of the kernel module when the device node is accessed. Ideally all these modules would be compiled-in, but distros seems too much in love with their modularization that we need to cover the common cases with this new facility. It will allow us to remove a bunch of pretty useless init scripts and modprobes from init scripts. The static device node aliases will be carried in the module itself. The program depmod will extract this information to a file in the module directory: $ cat /lib/modules/2.6.34-00650-g537b60d-dirty/modules.devname # Device nodes to trigger on-demand module loading. microcode cpu/microcode c10:184 fuse fuse c10:229 ppp_generic ppp c108:0 tun net/tun c10:200 dm_mod mapper/control c10:235 Udev will pick up the depmod created file on startup and create all the static device nodes which the kernel modules specify, so that these modules get automatically loaded when the device node is accessed: $ /sbin/udevd --debug ... static_dev_create_from_modules: mknod '/dev/cpu/microcode' c10:184 static_dev_create_from_modules: mknod '/dev/fuse' c10:229 static_dev_create_from_modules: mknod '/dev/ppp' c108:0 static_dev_create_from_modules: mknod '/dev/net/tun' c10:200 static_dev_create_from_modules: mknod '/dev/mapper/control' c10:235 udev_rules_apply_static_dev_perms: chmod '/dev/net/tun' 0666 udev_rules_apply_static_dev_perms: chmod '/dev/fuse' 0666 A few device nodes are switched to statically allocated numbers, to allow the static nodes to work. This might also useful for systems which still run a plain static /dev, which is completely unsafe to use with any dynamic minor numbers. Note: The devname aliases must be limited to the *common* and *single*instance* device nodes, like the misc devices, and never be used for conceptually limited systems like the loop devices, which should rather get fixed properly and get a control node for losetup to talk to, instead of creating a random number of device nodes in advance, regardless if they are ever used. This facility is to hide the mess distros are creating with too modualized kernels, and just to hide that these modules are not compiled-in, and not to paper-over broken concepts.

2010-05-25fb_defio: fix for non-dirty ptesAlbert Herranz
Fix a problem observed while using fb_defio with a short delay on a PowerPC platform. It is possible that page_mkclean() is invoked in the deferred io work function _before_ a PTE has been marked dirty. In this case, the page is removed from the defio pagelist but page_mkclean() does not write-protect the page again. The end result is that defio ignores all subsequent writes to the page and the corresponding portions of the framebuffer never get updated. The fix consists in keeping track of the pages with non-dirty PTEs, re-checking them again on the next deferred io work iteration. Note that those pages are not passed to the defio callback as they are not written by userspace yet.

Since the drivers probe calls were changed from .init.text to .devinit.text in commit c2e13037e6794bd0d9de3f9ecabf5615f15c160b ("platform-drivers: move probe to .devinit.text in drivers/video") all the function from .init.text should be moved to .devinit.text, too. The drivers remove calls can also be move from .text to .devexit.text.

2010-05-25fbdev: move FBIO_WAITFORVSYNC to linux/fb.hGrazvydas Ignotas
FBIO_WAITFORVSYNC is currently implemented by matroxfb, atyfb, intelfb and more. All of them keep redefining the same FBIO_WAITFORVSYNC macro over and over again, so move it to linux/fb.h and clean up those duplicate defines.

2010-05-25fbdev: da8xx/omap-l1xx: implement double bufferingMartin Ambrose
This work includes the following: - Implement handler for FBIO_WAITFORVSYNC ioctl. - Allocate the data and palette buffers separately. A consequence of this is that the palette and data loading is now done in different phases. And that the LCD must be disabled temporarily after the palette is loaded but this will only happen once after init and each time the palette is changed. I think this is OK. - Allocate two (ping and pong) framebuffers from memory. - Add pan_display handler which toggles the LCDC DMA registers between the ping and pong buffers.
