The mmu context on the 40x, 44x does not define pte_frag entry. This causes gcc abort the compilation due to: setup-common.c: In function ‘setup_arch’: setup-common.c:908: error: ‘mm_context_t’ has no ‘pte_frag’ This patch fixes the issue by removing the pte_frag initialization in setup-common.c. This is possible, because the compiler will do the initialization, since the mm_context is a sub struct of init_mm. init_mm is declared in mm_types.h as external linkage. According to C99 6.2.4.3: An object whose identifier is declared with external linkage [...] has static storage duration. C99 defines in 6.7.8.10 that: If an object that has static storage duration is not initialized explicitly, then: - if it has pointer type, it is initialized to a null pointer Fixes: b1923caa ("powerpc: Merge 32-bit and 64-bit setup_arch()") Signed-off-by:
