From 6bf11e8c708f0e512ed733fc65a50770c5bc7b54 Mon Sep 17 00:00:00 2001 From: "stephane.eranian@hp.com" Date: Thu, 28 Jul 2005 05:18:00 -0700 Subject: [IA64] fix perfmon context load The PFM_LOAD_CONTEXT may fail silently and cause a session to remain reserved even though it should not. This can happen when the commands succeeds in reserving the session but fails when it actually tries to attach to the load_pid. In that case, the command has failed but will return 0. More importantly, the session will remain reserved. This patch fixes the problem.

I'm not sure if duplicate mappings do any harm, but it's simply redundant. Also, in s3c2440.c the UART I/O mapping is NOT done. Additionally, I put a comma behind the last mapping, to ease copy/pasting stuff around, and make the style consistent with s3c2440.c and other files.

GCC 4.x really dislikes the games we are playing in unaligned.c, and the cleanest way to fix this is to move things into assembler. Noted by Al Viro. Signed-off-by: David S.

This fixes problems with the VM allowing too many dirty pages because it overestimates the number of available RAM in a node. In extreme cases you can end up with all RAM filled with dirty pages which can lead to deadlocks and other nasty behaviour. This patch just tells the VM about the known holes from e820. Reserved (like the kernel text or mem_map) is still not taken into account, but that should be only a few percent error now. Small detail is that the flat setup uses the NUMA free_area_init_node() now too because it offers more flexibility.
