Loongson CPUs have an annoying VIPT cache and 14 bits of virtual address are used for tagging. So either we need an excessive and difficult to maintain cache flushing or to use 16K or biger pages. Note than when configuring Linux on Yeeloong only page size of 16K and 64K are proposed. This patch fixes bunch of hardcoding of page size related constants and changes PAGE_SHIFT to 14 on Yeeloong. -- Regards Vladimir 'φ-coder/phcoder' Serbinenko
