The problems are that, with the ACPI vs timer overring issue _fixed_, after using the box for some time (between several seconds and 1 hour, at random) processes get very high CPU loads (once I've got X using 107% of the CPU, for example) and the system becomes unresponsive, as though there were interrupts lost or something similar.

So lets fall back to the IRQ0/INT0 configuration on this box. This basically restores the dont-use-the-lapic-timer exception mechanism that was unconditional on this box prior commit 8750bf5 ("x86: add C1E aware idle function"). Signed-off-by:

Reorder headers and collect globals in traps_32.c and traps_64.c Code size and data size are unaffected by the changes. Code itself is changed due to different ordering of data and bss. The bss segment changed size due to a change in the packing of the variables. Signed-off-by:

Merge the tsc calibration code for the 32bit and 64bit kernel. The paravirtualized calculate_cpu_khz for 64bit now points to the correct tsc_calibrate code as in 32bit. Original native_calculate_cpu_khz for 64 bit is now called as calibrate_cpu. Also moved the recalibrate_cpu_khz function in the common file. Note that this function is called only from powernow K7 cpu freq driver. Signed-off-by:

Move the basic global variable definitions and sched_clock handling in the common "tsc.c" file. - Unify notsc kernel command line handling for 32 bit and 64bit. - Functional changes for 64bit. - "tsc_disabled" is updated if "notsc" is passed at boottime. - Fallback to jiffies for sched_clock, incase notsc is passed on commandline.

With the removal of struct file from the xattr code, reiserfs_file_release() isn't used anymore, so the prealloc isn't discarded. This causes hangs later down the line. This patch adds it to reiserfs_delete_inode. In most cases it will be a no-op due to it already having been called, but will avoid hangs with xattrs. Signed-off-by:
