[ Andrew, read carefully, I think some part of a patch you merged might have been lost while reshuffling or whatever. ] This change: commit ba84be2338d3a2b6020d39279335bb06fcd332e1 Author: Russell King <rmk+kernel@xxxxxxxxxxxxxxxx> Date: Tue Jan 6 14:41:07 2009 -0800 remove linux/hardirq.h from asm-generic/local.h broke the build on sparc64: drivers/base/topology.c: In function ‘show_physical_package_id’: drivers/base/topology.c:103: error: implicit declaration of function ‘cpu_data’ drivers/base/topology.c:103: error: request for member ‘proc_id’ in something not a structure or union drivers/base/topology.c: In function ‘show_core_id’: drivers/base/topology.c:106: error: request for member ‘core_id’ in something not a structure or union Even though there is a footnote there from Alexey saying that sparc64 was fixed up :-) [adobriyan@xxxxxxxxx: fix sparc64] I've spent most of last night and this morning trying to figure out a way to fix this, it is very non-trivial. Adding a simple asm/cpudata.h include into asm/topology_64.h for the SMP case does not work. asm/cpudata.h brings in percpu.h which wants SLAB which wants to use GFP_* values and thus includes gfp.h And thus because of the include loop: linux/gfp.h --> linux/mmzone.h --> linux/topology.h --> asm/topology.h --> asm/cpudata.h --> linux/percpu.h --> linux/slab.h we can't include asm/cpudata.h into asm/topology.h otherwise we get: include/linux/slub_def.h: In function ‘kmalloc_large’: include/linux/slub_def.h:209: error: implicit declaration of function ‘__get_free_pages’ include/linux/slub_def.h:209: error: ‘__GFP_COMP’ undeclared (first use in this function) include/linux/slub_def.h:209: error: (Each undeclared identifier is reported only once include/linux/slub_def.h:209: error: for each function it appears in.) include/linux/slub_def.h:209: warning: cast to pointer from integer of different size for the drivers/base/topology.o build failure case above. Actually, looking at the patch, where is the part from Alexey that does the "fix sparc64"? I see nothing in the patch that would even appear to possibly be for that. The diffstat is: arch/avr32/kernel/traps.c | 1 + arch/sh/kernel/traps_32.c | 1 + drivers/acpi/processor_idle.c | 1 + include/asm-generic/local.h | 1 - 4 files changed, 3 insertions(+), 1 deletion(-) Was Alexey's fix removed or lost? :-/ ��.n��������+%������w��{.n������ܖ)�����ܨ}���Ơz�j:+v�����w����ޙ��&�)ߡ�a����z�ޗ���ݢj��w�f
