linux-toradex.git/arch/sparc, branch v2.6.23.17 Linux kernel for Apalis and Colibri modules [SPARC]: Fix EBUS use of uninitialized variable. 2007-09-27T20:09:28+00:00 David S.

[SPARC32]: Remove superfluous 'kernel_end' alignment on sun4c. 2007-08-15T01:24:10+00:00 Mark Fortescue mark@mtfhpc.demon.co.uk 2007-08-15T01:24:10+00:00 70b0e7a919b7961285c685a87928ed78c9fb07f0 In sun4c_init_clean_mmu(), aligning 'kernel_end' using SUN4C_REAL_PGDIR_ALIGN() is unnecessary since the caller does this already. In sun4c_paging_init(), 4 page sizes of "fluff" were added to the address of &end. This was necessary a long time ago when sparc32 would allocate some early data structures by carving out memory chunks after &end but that no longer occurs.
