Solved.

q) skas/mmu.c is calling pte_alloc_map() without ->page_table_lock. Trivially fixed, needed if you want spinlock debugging to produce something useful. r) when built static, kernel dies ugly death with #0 0x00000000601e4178 in ptmalloc_init () at swab.h:134 #1 0x00000000601e4034 in malloc_hook_ini () at swab.h:134 #2 0x00000000601e1698 in malloc () at swab.h:134 #3 0x00000000602068ee in _dl_init_paths () at swab.h:134 #4 0x00000000601eba45 in _dl_non_dynamic_init () at swab.h:134 #5 0x00000000601ebc60 in __libc_init_first () at swab.h:134 #6 0x00000000601cfa4f in __libc_start_main () at swab.h:134 #7 0x000000006001202a in _start () at proc_fs.h:183 as stack trace. Buggered offsets in uml.lds, perhaps?
Dynamically built it works; for i386 the same tree works both with both static and dynamic. It _might_ be libc difference, in theory (i386 libc is 2.3.2.ds1-18, amd64 - 2.3.2.ds1-21, both from sarge), but I wouldn't bet on it. Anyway, I'm going down right now; carving the fixes into sane patch series + experimenting with static/amd64 breakage will have to wait until the morning... - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
