MIPS: Loongson: Switch from flatmem to sparsemem

2009-12-01T16:21:26Z

With flatmem hibernation for Loongson will fail, and there are also some other problems such as broken files when using NFS or CIFS / Samba. The config help of sparsemem says: "This option provides some potential performance benefits, along with decreased code complexity." So to avoid the potential problems of FLATMEM, we disable FLATMEM directly and use SPARSEMEM instead.

MIPS: Loongson: Disallow 4kB pages

2009-12-01T16:21:26Z

Currently, with PAGE_SIZE_4KB, the kernel for loongson will hang on: Kernel panic - not syncing: Attempted to kill init! The possible reason is the cache aliases problem: Loongson 2F has 64kb, 4 way L1 Cache, the way size is 16kb, which is bigger then 4kb. so, If using 4kb page size, there is cache aliases problem. To avoid this kind of problem, extra cache flushing. The 2nd possible solution is 16kb page size which avoids cache aliases without the need for extra cache flushes. So we disable 4kB pages until the aliasing issue is solved.

MIPS: Add missing definition for MADV_HWPOISON.

MIPS: Fix build error if __xchg() is not getting inlined.

2009-12-01T16:21:25Z

If __xchg() is not getting inlined the outline version of the function will have a reference to __xchg_called_with_bad_pointer() which does not exist remaining. Fixed by using BUILD_BUG_ON() to check for allowable operand sizes. Signed-off-by: Ralf Baechle Patchwork: http://patchwork.linux-mips.org/patch/705/

MIPS: IP22/IP28 Disable early printk to fix boot problems on some systems.

2009-12-01T16:21:25Z

Some Debian users have reported that the kernel hangs early during boot on some IP22 systems. Thomas Bogendoerfer found that this is due to a "bad interaction between CONFIG_EARLY_PRINTK and overwritten prom memory during early boot". Since there's no fix yet, disable CONFIG_EARLY_PRINTK for now.

The typename member of struct irq_chip was kept for migration purposes and is obsolete since more than 2 years. Fix up the leftovers. Signed-off-by: Thomas Gleixner Cc: Richard Henderson Cc: linux-alpha@vger.kernel.org Signed-off-by: Matt Turner
