2009-06-11Revert "x86, bts: reenable ptrace branch trace support"Ingo Molnar
This reverts commit 7e0bfad24d85de7cf2202a7b0ce51de11a077b21. A late objection to the ABI has arrived: http://lkml.org/lkml/2009/6/10/253 Keep the ABI disabled out of caution, to not create premature user-space expectations. While the hw-branch-tracing variant uses and tests the BTS code.

2009-06-10CPUFREQ: Mark e_powersaver driver as EXPERIMENTAL and DANGEROUSHarald Welte
The e_powersaver driver for VIA's C7 CPU's needs to be marked as DANGEROUS as it configures the CPU to power states that are out of specification. According to Centaur, all systems with C7 and Nano CPU's support the ACPI p-state method. Thus, the acpi-cpufreq driver should be used instead.

The VIA/Centaur C7, C7-M and Nano CPU's all support ACPI based cpu p-states using a MSR interface. The Linux driver just never made use of it, since in addition to the check for the EST flag it also checked if the vendor is Intel.

2009-06-10floppy: fix hibernationOndrej Zary
Based on Ingo Molnar's patch from 2006, this makes the floppy work after resume from hibernation, at least on my machine. This fix resets the floppy controller on resume. It was experimentally determined to bring the controller back to life - we don't really know why it works. floppy_init() does the same thing at boot/modprobe time.

2009-06-10block: prevent possible io_context->refcount overflowNikanth Karthikesan
Currently io_context has an atomic_t(32-bit) as refcount. In the case of cfq, for each device against whcih a task does I/O, a reference to the io_context would be taken. And when there are multiple process sharing io_contexts(CLONE_IO) would also have a reference to the same io_context. Theoretically the possible maximum number of processes sharing the same io_context + the number of disks/cfq_data referring to the same io_context can overflow the 32-bit counter on a very high-end machine. Even though it is an improbable case, let us make it atomic_long_t.

By moving the macro that creates the print format code above the defining of the event macro helpers (__get_str, __print_symbolic, and __get_dynamic_array), we get a little cleaner print format. Instead of: (char *)((void *)REC + REC->__data_loc_name) we get: __get_str(name) Instead of: ({ static const struct trace_print_flags symbols[] = { { HI_SOFTIRQ, "HI" }, { we get: __print_symbolic(REC->vec, { HI_SOFTIRQ, "HI" }, { Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
2009-06-10ext4: Avoid corrupting the uninitialized bit in the extent during truncateAneesh Kumar K.V
The unitialized bit was not properly getting preserved in in an extent which is partially truncated because the it was geting set to the value of the first extent to be removed or truncated as part of the truncate operation, and if there are multiple extents are getting removed or modified as part of the truncate operation, it is only the last extent which will might be partially truncated, and its uninitalized bit is not necessarily the same as the first extent to be truncated.

2009-06-10cifs: add addr= mount option alias for ip=Jeff Layton
When you look in /proc/mounts, the address of the server gets displayed as "addr=". That's really a better option to use anyway since it's more generic. What if we eventually want to support non-IP transports? It also makes CIFS option consistent with the NFS option of the same name.
