- Move alignment of init data to page size outside define CONFIG_BLK_DEV_INITRD This avoids oops due to memory on the same page as init data being freed. - Change hardcoded page size to use macro from asm/page.h - Add reserved memory via CONFIG_ETRAX_VMEM_SIZE. - Use available defines for TEXT_TEXT and INITCALLS. - Cleanup whitespace.

2008-02-08CRIS v32: Update kernel/crisksyms.cJesper Nilsson1-1/+6
- Include pinmux.h from machine specific directory. - Add some more symbols: crisv32_pinmux_alloc, crisv32_pinmux_dealloc_fixed, crisv32_io_get_name and crisv32_io_get
