2010-05-26ARM: S5PC100: Fixup cross tree merge problemsBen Dooks1-5/+2
The commit 45c79433c02b8fe7b8a1cbf60548a9798d0502ed got things building but then commit 17d2f877ae8b68b09bf88a9949ee64fbbda5ee10 and others where merged in from a seperate tree and this has resulted from a build failure due to the redefinition of IRQ_EINT(). Fix this by merging a new commit. Signed-off-by: Ben Dooks <[email protected]>
2010-05-26ARM: S5P: Fix the platform external interrupt issues.Pannaga Bhushan8-28/+40
This patch does the following: 1. Corrects the common platform code for external interrupts for using the VIC mask/unmask bits also. 2. Moves the common defines related to external interrupt for plat-s5p to common files. 3. Based on the new common defines, corresponding changes are made in the affected platforms (S5P6440, S5P6442 and S5PC100).

2010-05-25sparc32: Kill none_mask, it's bogus.David S. Miller3-8/+2
For some reason, the pte_none() calculation for srmmu sparc32 chips was masking out the top 4 bits. That doesn't make any sense, as those are just some of the physical bits of the PTE encoding. Furthermore, this mistake breaks things when the offset of of a swap entry has a large enough offset as reported by Тхай Кирилл. Sun4c always set it to zero, so it's really completely useless, kill it. Reported-by: Тхай Кирилл <[email protected]> Signed-off-by: David S. Miller <[email protected]>

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 Sievers1-0/+1
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.

2010-05-25endian: #define __BYTE_ORDERJoakim Tjernlund7-31/+2
Linux does not define __BYTE_ORDER in its endian header files which makes some header files bend backwards to get at the current endian. Lets #define __BYTE_ORDER in big_endian.h/litte_endian.h to make it easier for header files that are used in user space too. In userspace the convention is that 1. _both_ __LITTLE_ENDIAN and __BIG_ENDIAN are defined, 2. you have to test for e.g. __BYTE_ORDER == __BIG_ENDIAN.

2010-05-24powerpc/kexec: Add support for FSL-BookESebastian Andrzej Siewior6-1/+74
This adds support kexec on FSL-BookE where the MMU can not be simply switched off. The code borrows the initial MMU-setup code to create the identical mapping mapping. The only difference to the original boot code is the size of the mapping(s) and the executeable address. The kexec code maps the first 2 GiB of memory in 256 MiB steps. This should work also on e500v1 boxes. SMP support is still not available. (Kumar: Added minor change to build to ifdef CONFIG_PPC_STD_MMU_64 some code that was PPC64 specific) Signed-off-by: Sebastian Andrzej Siewior <[email protected]> Signed-off-by: Kumar Gala <[email protected]>
