| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some powerpc machines can support 64k pages, enabled by the CONFIG_64K_PAGES option in linux. However, the uClibc dynamic loader won't currently work on these machines, as it uses hard-coded values (PAGE_ALIGN, ADDR_ALIGN and OFFS_ALIGN) in the ldso architecture-specific headers. When running on a kernel with 64k pages, ld.so tries to mmap with 4k-aligned addresses, rather than 64k, so mmap fails with -EINVAL. When booting a 64k machine with a uClibc dynamic linker, init fails with: /init:500: can't map '/lib/libc.so.0' /init:500: can't map '/lib/libc.so.0' /init:500: can't map '/lib/libc.so.0' /init: can't load library 'libc.so.0' Kernel panic - not syncing: Attempted to kill init! This change allows ld.so determine these alignment masks at runtime, rather than compile-time. Since we have the _dl_pagesize variable available, we can use that to generate the appropriate masks. Since almost all of the architectures can use the common definitions for the _ALIGN macros, we can consolidate them all in ldso.h, and override in the sysdep headers where necessary (ie, mips). This allows me to start a uClibc-based root fs on a 64k machine. Signed-off-by: Jeremy Kerr <jk at ozlabs org>
