Hi, Trying to compile i386 kernel with CONFIG_HIGHMEM64G=y using gcc-2.7.2.3 I observe problem with some inline functions:
mm/mm.o: In function `vmalloc_area_pages': mm/mm.o(.text+0xad18): undefined reference to `set_pgdir' mm/mm.o: In function `__vmalloc': mm/mm.o(.text+0xb41d): undefined reference to `set_pgdir' mm/mm.o: In function `swap_out_vma': mm/mm.o(.text+0xcfeb): undefined reference to `pgd_bad' mm/mm.o: In function `unuse_vma': mm/mm.o(.text+0xe944): undefined reference to `pgd_bad' fs/fs.o: In function `statm_pgd_range': fs/fs.o(.text+0x1dfa6): undefined reference to `pgd_bad' drivers/char/drm/drm.o: In function `_drm_vma_info': drivers/char/drm/drm.o(.text+0x26ba): undefined reference to `pte_young' drivers/char/drm/drm.o(.text+0x26d7): undefined reference to `pte_dirty' drivers/char/drm/drm.o(.text+0x26f4): undefined reference to `pte_exec' drivers/char/drm/drm.o(.text+0x2711): undefined reference to `pte_write' drivers/char/drm/drm.o(.text+0x272e): undefined reference to `pte_read' make: *** [vmlinux] Error 1
nm mm/memory.o shows:
00000004 C num_physpages U pager_daemon 000024a8 t partial_clear U pgd_bad <---------- shouldn't happen for inline function 00000004 D pgt_cache_water U printk U read_swap_cache_async
I see that problem is with inline functions with 64-bit arguments. Converting the inlines to operate on pointers seems to fix this problem. Is it the right way to fix them? (It should be cheap) Or: - should they be converted to non-inlines (expensive) - should gcc-2.7.2.3 be dropped (eventually dropped for some config options) ?
Regards Andrzej
