[POWERPC] Fix build failure on Cell when CONFIG_SPU_FS=y

2008-01-02T04:56:30Z

Commit aed3a8c9bb1a8623a618232087c5ff62718e3b9a introduced a definition of notify_spus_active in .../cell/spu_syscalls.c, and another definition under #ifndef MODULE in .../cell/spufs/sched.c. The latter is not necessary and causes the build to fail when CONFIG_SPU_FS=y, so this removes it. It also removes the export of do_notify_spus_active, which is unnecessary.

[POWERPC] Oprofile: Remove dependency on spufs module

2007-12-28T04:07:52Z

This removes an OProfile dependency on the spufs module. This dependency was causing a problem for multiplatform systems that are built with support for Oprofile on Cell but try to load the oprofile module on a non-Cell system.

[POWERPC] spufs: Fix context destroy vs /spu readdir race

2007-11-20T05:10:20Z

We can currently cause an oops by repeatedly creating and destroying contexts, while doing getdents() calls on the "/spu" directory. This is due to the context's top-level dentry remaining hashed while the context is being destroyed. Fix this by unhashing the context's dentry with the dentry->d_inode->i_mutex held. This way, we'll hit the check for d_unhashed in dentry_readdir, and won't be included in the list of subdirs for /spu. test: spufs-testsuite:tests/01-spu_create/07-destroy-vs-readdir-race Signed-off-by: Jeremy Kerr Signed-off-by: Paul Mackerras

[POWERPC] Include udbg.h when using udbg_printf

2007-11-08T03:15:31Z

This fixes the error error: implicit declaration of function "udbg_printf" We have a few spots where we reference udbg_printf() without #including udbg.h. These are within #ifdef DEBUG blocks, so unnoticed until we do a #define DEBUG or #define DEBUG_LOW nearby. Signed-off-by: Will Schmidt Signed-off-by: Paul Mackerras

[POWERPC] Fix CONFIG_SMP=n build break

2007-11-08T03:15:30Z

Fix two build errors on powerpc allyesconfig + CONFIG_SMP=n: arch/powerpc/platforms/built-in.o: In function `cpu_affinity_set': arch/powerpc/platforms/cell/spu_priv1_mmio.c:78: undefined reference to `.iic_get_target_id' arch/powerpc/platforms/built-in.o: In function `iic_init_IRQ': arch/powerpc/platforms/cell/interrupt.c:397: undefined reference to `.iic_setup_cpu' Signed-off-by: Olof Johansson Acked-by: Arnd Bergmann Signed-off-by: Paul Mackerras

Convert files to UTF-8 and some cleanups

2007-10-19T21:21:04Z

* Convert files to UTF-8. * Also correct some people's names (one example is Eißfeldt, which was found in a source file. Given that the author used an ß at all in a source file indicates that the real name has in fact a 'ß' and not an 'ss', which is commonly used as a substitute for 'ß' when limited to 7bit.) * Correct town names (Goettingen -> Göttingen) * Update Eberhard Mönkeberg's address (http://lkml.org/lkml/2007/1/8/313) Signed-off-by: Jan Engelhardt Signed-off-by: Adrian Bunk

Slab API: remove useless ctor parameter and reorder parameters

2007-10-17T15:42:45Z

Slab constructors currently have a flags parameter that is never used. And the order of the arguments is opposite to other slab functions. The object pointer is placed before the kmem_cache pointer. Convert ctor(void *object, struct kmem_cache *s, unsigned long flags) to ctor(struct kmem_cache *s, void *object) throughout the kernel [akpm@linux-foundation.org: coupla fixes] Signed-off-by: Christoph Lameter Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

Convert cpu_sibling_map to be a per cpu variable

2007-10-16T16:42:50Z

Convert cpu_sibling_map from a static array sized by NR_CPUS to a per_cpu variable. This saves sizeof(cpumask_t) * NR unused cpus. Access is mostly from startup and CPU HOTPLUG functions.

Remove msic_dcr_read() in axon_msi.c

msic_dcr_read() doesn't really do anything useful, just replace it with direct calls to dcr_read(). Signed-off-by: Michael Ellerman Signed-off-by: Jeff Garzik

Add dcr_host_t.base in dcr_read()/dcr_write()

2007-10-15T18:29:49Z

Now that all users of dcr_read()/dcr_write() add the dcr_host_t.base, we can save them the trouble and do it in dcr_read()/dcr_write(). As some background to why we just went through all this jiggery-pokery, benh sayeth: Initially the goal of the dcr_read/dcr_write routines was to operate like mfdcr/mtdcr which take absolute DCR numbers. The reason is that on 4xx hardware, indirect DCR access is a pain (goes through a table of instructions) and it's useful to have the compiler resolve an absolute DCR inline. We decided that wasn't worth the API bastardisation since most places where absolute DCR values are used are low level 4xx-only code which may as well continue using mfdcr/mtdcr, while the new API is designed for device "instances" that can exist on 4xx and Axon type platforms and may be located at variable DCR offsets.
