From c39f52a9edc5e0687cbb54c08bcd78cf7fe26b62 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Thu, 3 May 2012 09:02:57 +0000 Subject: parisc: Use generic init_task Same code, except: The alignment of init_thread_union is handled via the linker script, so no point to have it with the data structure. The extra asm(".data") looks like a leftover from an asm to C conversion and is pointless. Use the generic version. Move the page table data to parisc/mm/init.c and get rid of parisc/../init_task.c Signed-off-by: Thomas Gleixner Cc: James E.J.
