* [CPUFREQ] Move PMBASE reading away and do it only once at initialization timeMattia Dongili2005-12-06
| | | | | | | | | | This patch moves away PMBASE reading and only performs it at cpufreq_register_driver time by exiting with -ENODEV if unable to read the value.

* [CPUFREQ] Measure transition latency at driver initializationMattia Dongili2005-12-06
| | | | | | | | | | | | | | | | | | | | | The attached patch introduces runtime latency measurement for ICH[234] based chipsets instead of using CPUFREQ_ETERNAL. It includes some sanity checks in case the measured value is out of range and assigns a safe value of 500uSec that should still be enough on problematics chipsets (current testing report values ~200uSec). The measurement is currently done in speedstep_get_freqs in order to avoid further unnecessary transitions and in the hope it'll come handy for SMI also.

| * | [PATCH] ppc32: fix treeboot image entrypointEugene Surovegin2005-12-01

Currently makefile uses $(ENTRYPOINT) which isn't defined anywhere. Each board port sets entrypoint-$(CONFIG_BOARD_NAME) instead. Without this patch I cannot boot Ocotea (PPC440GX eval board) anymore. I was getting random "OS panic" errors from OpenBIOS for a while, but with current kernel I get them all the time (probably because image became bigger).

| | * [IA64] Remove getting break_num by decoding instructionKeshavamurthy Anil S2005-11-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | break.b always sets cr.iim to 0 and the current code tries to get the break_num by decoding instruction. However, their seems to be a race condition while reading the regs->cr_iip, as on other cpu the break.b at regs->cr_iip might have been replaced with the original instruction as a result of unregister_kprobe() and hence decoding instruction to obtain break_num will result in wrong value in this case. Also includes changes to kprobes.c which now has to handle break number zero. Signed-off-by: Anil S Keshavamurthy <anil.s.keshavamurthy@intel.com> Signed-off-by: Tony Luck <tony.luck@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We must not call TLB maintainence operations with interrupts disabled, otherwise we risk a lockup in the SMP IPI code. This means that consistent_free() can not be called from a context with IRQs disabled. In addition, we must not hold the lock in consistent_free when we call flush_tlb_kernel_range(). However, we must continue to prevent consistent_alloc() from re-using the memory region until we've finished tearing down the mapping and dealing with the TLB. Therefore, leave the vm_region entry in the list, but mark it inactive before dropping the lock and starting the tear-down process. After the mapping has been torn down, re-acquire the lock and remove the entry from the list. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
