2006-02-10[PATCH] x86: don't initialise cpu_possible_map to all onesAndrew Morton
Initialising cpu_possible_map to all-ones with CONFIG_HOTPLUG_CPU means that a) All for_each_cpu() loops will iterate across all NR_CPUS CPUs, rather than over possible ones. That can be quite expensive. b) Soon we'll be allocating per-cpu areas only for possible CPUs. So with CPU_MASK_ALL, we'll be wasting memory. I also switched voyager over to not use CPU_MASK_ALL in the non-CPU-hotplug case. Should be OK.. I note that parisc is also using CPU_MASK_ALL. Suggest that it stop doing that.

2006-02-10[PATCH] Fix building external modules on ppc32Andreas Gruenbacher
We are setting up sources for building external modules like this: /usr/src/linux-obj> # create a .config file /usr/src/linux-obj> make -C /usr/src/linux O=$PWD oldconfig /usr/src/linux-obj> make -C /usr/src/linux O=$PWD prepare /usr/src/linux-obj> make -C /usr/src/linux O=$PWD scripts /usr/src/linux-obj> make -C /usr/src/linux O=$PWD clean After that, external modules can be built with: /usr/src/module> make -C /usr/src/linux-obj M=$PWD This fails for ppc32 because the `make clean' removes the arch/powerpc/include directory. This should be done in archmrproper instead of in archclean.

2006-02-08[ARM] 3310/1: add a comment about the possible __kuser_cmpxchg transient falseNicolas Pitre
negative Patch from Nicolas Pitre The pre ARMv5 implementation can be aborted if an exception occurs in the middle of it. Because of that, the ARMv6 implementation doesn't re-attempt the operation on a failed strex either. Let's make this transient nature of such a false positive more explicit in the definition.

2006-02-08[ARM] 3309/1: disable the pre-ARMv5 NPTL kernel helper in the non MMU caseNicolas Pitre
Patch from Nicolas Pitre The cmpxchg emulation on pre-ARMv5 relies on user code executed from a kernel address. If the operation cannot complete atomically, it is aborted from the usr_entry macro by clearing the Z flag. This clearing of the Z flag is done whenever the user pc is above TASK_SIZE. However this "pc >= TASK_SIZE" test cannot work in the non MMU case. Worse: the current code will corrupt the Z flag on every entry to the kernel. Let's disable it in the non MMU case for now. Using NPTL on non MMU targets needs to be worked out anyway. Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-02-08[ARM] 3308/1: old ABI compat: struct sockaddr_unNicolas Pitre

All the percpu data structure walkers want cpu_possible_map to be initialized early, but alpha instead populated "hwrpb_cpu_present_mask" early in setup_smp(), and then initialized cpu_possible_map only much later.
