[PATCH] Introduce boot based time

and process start time calculations then. Also, the uptime no longer increases during suspend. I add a variable to track the wall_to_monotonic changes, a function to get the real boot time and a function to get the boot based time from the monotonic one.

[PATCH] Use boot based time for uptime in /proc

Commit 411187fb05cd11676b0979d9fbf3291db69dbce2 caused uptime not to increase during suspend. This may cause confusion so I restore the old behaviour by using the boot based time instead of monotonic for uptime. Signed-off-by: Tomas Janousek <[EMAIL PROTECTED]> --- fs/proc/proc_misc.c

Commit 411187fb05cd11676b0979d9fbf3291db69dbce2 caused boot time to move and process start times to become invalid after suspend. Using boot based time for those restores the old behaviour and fixes the issue. Signed-off-by: Tomas Janousek <[EMAIL PROTECTED]> Cc: Tomas Smetana <[EMAIL
