The attr.branch_sample_type field is defined as u64 by the API. As such, we need to ensure the variable holding the value of the branch stack filters is also u64 otherwise we may lose bits in the future. Note also that the bogus definition of the field in perf_record_opts caused problems on big-endian PPC systems. Thanks to Anshuman Khandual for tracking the problem on PPC.

The modifiers: k kernel space u user space h hypervisor G guest H host p, pp, ppp precision level (PEBS) that can be suffixed to an event were lost when tools used event_name() to reconstruct them from the perf_event_attr entries in a perf.data file. Fix it by following the defaults used for these modifiers in the current codebase, so: $ perf record -e instructions:u usleep 1 2> /dev/null $ perf evlist instructions:u $ perf record -e cycles:k usleep 1 2> /dev/null $ perf evlist cycles:k $ perf record -e cycles:kh usleep 1 2> /dev/null $ perf evlist cycles:kh $ perf record -e cache-misses:G usleep 1 2> /dev/null $ perf evlist cache-misses:G $ perf record -e cycles:ppk usleep 1 2> /dev/null $ perf evlist cycles:kpp $ Also works with 'top', 'report', etc. More work needed to cover tracepoints and software events while not dragging lots of baggage to the python binding, this is a minimal fix for v3.5.

In 40491eaa "perf top: Update event name when falling back to cpu-clock" we freed counter->name but didn't reset it to NULL, then when setting it to the result of event_name(), event_name() would use the cached value, which by now was overwritten and thus we got garbage or a zero lenght string. Fix it by just freeing and setting counter->name to NULL, this way event_name() when called afterwards, will find the right counter name and cache it again. Found while trying 'cycles:pp' on a machine were :pp couldn't be honoured. Probably the best fallback here is to tell the user that that level of precision is not available on the PMU and then go removing 'p', levels of precision till we get to play 'cycles' and if even that fails, _then_ get to 'cpu-clock'. But that is the matter for another patch, this one just needs to fix the caching issue, which in the end will show 'cpu-clock' when tools ask for the event name being used, which clarifies things for the user, that will see that 'cycles:pp' or whatever not support event is not being used, some sort of fallback happened.

In the event of splits, mpol_dup() will allocate a new struct mempolicy and maintain existing reference counts whose rules are documented in Documentation/vm/numa_memory_policy.txt . The problem occurs with shared memory policies. The vm_op->set_policy increments the reference count if necessary and split_vma() and vma_merge() have already handled the existing reference counts. However, policy_vma() screws it up by replacing an existing vma->vm_policy with one that potentially has the wrong reference count leading to a premature free. This patch removes the damage caused by policy_vma(). With this patch applied Dave's trinity tool runs an mbind test for 5 minutes without error. /proc/slabinfo reported that there are no numa_policy or shared_policy_node objects allocated after the test completed and the shared memory region was deleted.

Pull user namespace enhancements from Eric Biederman: "This is a course correction for the user namespace, so that we can reach an inexpensive, maintainable, and reasonably complete implementation. Highlights: - Config guards make it impossible to enable the user namespace and code that has not been converted to be user namespace safe. - Use of the new kuid_t type ensures the if you somehow get past the config guards the kernel will encounter type errors if you enable user namespaces and attempt to compile in code whose permission checks have not been updated to be user namespace safe. - All uids from child user namespaces are mapped into the initial user namespace before they are processed. Removing the need to add an additional check to see if the user namespace of the compared uids remains the same. - With the user namespaces compiled out the performance is as good or better than it is today. - For most operations absolutely nothing changes performance or operationally with the user namespace enabled. - The worst case performance I could come up with was timing 1 billion cache cold stat operations with the user namespace code enabled. This went from 156s to 164s on my laptop (or 156ns to 164ns per stat operation). - (uid_t)-1 and (gid_t)-1 are reserved as an internal error value. Most uid/gid setting system calls treat these value specially anyway so attempting to use -1 as a uid would likely cause entertaining failures in userspace. - If setuid is called with a uid that can not be mapped setuid fails. I have looked at sendmail, login, ssh and every other program I could think of that would call setuid and they all check for and handle the case where setuid fails. - If stat or a similar system call is called from a context in which we can not map a uid we lie and return overflowuid. The LFS experience suggests not lying and returning an error code might be better, but the historical precedent with uids is different and I can not think of anything that would break by lying about a uid we can't map. - Capabilities are localized to the current user namespace making it safe to give the initial user in a user namespace all capabilities.

Pull the MCA deletion branch from Paul Gortmaker: "It was good that we could support MCA machines back in the day, but realistically, nobody is using them anymore. They were mostly limited to 386-sx 16MHz CPU and some 486 class machines and never more than 64MB of RAM. Even the enthusiast hobbyist community seems to have dried up close to ten years ago, based on what you can find searching various websites dedicated to the relatively short lived hardware. So lets remove the support relating to CONFIG_MCA. There is no point carrying this forward, wasting cycles doing routine maintenance on it; wasting allyesconfig build time on validating it, wasting I/O on git grep'ping over it, and so on." Let's see if anybody screams. It generally has compiled, and James Bottomley pointed out that there was a MCA extension from NCR that allowed for up to 4GB of memory and PPro-class machines. So in *theory* there may be users out there. But even James (technically listed as a maintainer) doesn't actually have a system, and while Alan Cox claims to have a machine in his cellar that he offered to anybody who wants to take it off his hands, he didn't argue for keeping MCA support either. So we could bring it back. But somebody had better speak up and talk about how they have actually been using said MCA hardware with modern kernels for us to do that.

Pull sound updates from Takashi Iwai: "This is the first big chunk for 3.5 merges of sound stuff. There are a few big changes in different areas. First off, the streaming logic of USB-audio endpoints has been largely rewritten for the better support of "implicit feedback". If anything about USB got broken, this change has to be checked. For HD-audio, the resume procedure was changed; instead of delaying the resume of the hardware until the first use, now waking up immediately at resume. This is for buggy BIOS. For ASoC, dynamic PCM support and the improved support for digital links between off-SoC devices are major framework changes. Some highlights are below: * HD-audio - Avoid accesses of invalid pin-control bits that may stall the codec - V-ref setup cleanups - Fix the races in power-saving code - Fix the races in codec cache hashes and connection lists - Split some common codes for BIOS auto-parser to hda_auto_parser.c - Changed the PM resume code to wake up immediately for buggy BIOS - Creative SoundCore3D support - Add Conexant CX20751/2/3/4 codec support * ASoC - Dynamic PCM support, allowing support for SoCs with internal routing through components with tight sequencing and formatting constraints within their internal paths or where there are multiple components connected with CPU managed DMA controllers inside the SoC. - Greatly improved support for direct digital links between off-SoC devices, providing a much simpler way of connecting things like digital basebands to CODECs. - Much more fine grained and robust locking, cleaning up some of the confusion that crept in with multi-component. - CPU support for nVidia Tegra 30 I2S and audio hub controllers and ST-Ericsson MSP I2S controolers - New CODEC drivers for Cirrus CS42L52, LAPIS Semiconductor ML26124, Texas Instruments LM49453. - Some regmap changes needed by the Tegra I2S driver. - mc13783 audio support. * Misc - Rewrite with module_pci_driver() - Xonar DGX support for snd-oxygen - Improvement of packet handling in snd-firewire driver - New USB-endpoint streaming logic - Enhanced M-audio FTU quirks and relevant cleanups - Increment the support of OSS devices to 256 - snd-aloop accuracy improvement There are a few more pending changes for 3.5, but they will be sent slightly later as partly depending on the changes of DRM."

On some machines the number of possible CPUS is not the same as the number of CPUs that is on the machine. Ftrace uses possible_cpus to update the tracing structures but the ring buffer only allocates per cpu buffers for online CPUs when they come up. When the wakeup tracer was enabled in such a case, the ftrace code enabled all possible cpu buffers, but the code in ring_buffer_resize() did not check to see if the buffer in question was allocated. Since boot up CPUs did not match possible CPUs it caused the following crash: BUG: unable to handle kernel NULL pointer dereference at 00000020 IP: [<c1097851>] ring_buffer_resize+0x16a/0x28d *pde = 00000000 Oops: 0000 [#1] PREEMPT SMP Dumping ftrace buffer: (ftrace buffer empty) Modules linked in: [last unloaded: scsi_wait_scan] Pid: 1387, comm: bash Not tainted 3.4.0-test+ #13 /DG965MQ EIP: 0060:[<c1097851>] EFLAGS: 00010217 CPU: 0 EIP is at ring_buffer_resize+0x16a/0x28d EAX: f5a14340 EBX: f6026b80 ECX: 00000ff4 EDX: 00000ff3 ESI: 00000000 EDI: 00000002 EBP: f4275ecc ESP: f4275eb0 DS: 007b ES: 007b FS: 00d8 GS: 00e0 SS: 0068 CR0: 80050033 CR2: 00000020 CR3: 34396000 CR4: 000007d0 DR0: 00000000 DR1: 00000000 DR2: 00000000 DR3: 00000000 DR6: ffff0ff0 DR7: 00000400 Process bash (pid: 1387, ti=f4274000 task=f4380cb0 task.ti=f4274000) Stack: c109cf9a f6026b98 00000162 00160f68 00000006 00160f68 00000002 f4275ef0 c109d013 f4275ee8 c123b72a c1c0bf00 c1cc81dc 00000005 f4275f98 00000007 f4275f70 c109d0c7 7700000e 75656b61 00000070 f5e90900 f5c4e198 00000301 Call Trace: [<c109cf9a>] ? tracing_set_tracer+0x115/0x1e9 [<c109d013>] tracing_set_tracer+0x18e/0x1e9 [<c123b72a>] ? _copy_from_user+0x30/0x46 [<c109d0c7>] tracing_set_trace_write+0x59/0x7f [<c10ec01e>] ? fput+0x18/0x1c6 [<c11f8732>] ? security_file_permission+0x27/0x2b [<c10eaacd>] ? rw_verify_area+0xcf/0xf2 [<c10ec01e>] ? fput+0x18/0x1c6 [<c109d06e>] ? tracing_set_tracer+0x1e9/0x1e9 [<c10ead77>] vfs_write+0x8b/0xe3 [<c10ebead>] ? fget_light+0x30/0x81 [<c10eaf54>] sys_write+0x42/0x63 [<c1834fbf>] sysenter_do_call+0x12/0x28 This happens with the latency tracer as the ftrace code updates the saved max buffer via its cpumask and not with a global setting.

Pull exception table generation updates from Ingo Molnar: "The biggest change here is to allow the build-time sorting of the exception table, to speed up booting. This is achieved by the architecture enabling BUILDTIME_EXTABLE_SORT. This option is enabled for x86 and MIPS currently. On x86 a number of fixes and changes were needed to allow build-time sorting of the exception table, in particular a relocation invariant exception table format was needed. This required the abstracting out of exception table protocol and the removal of 20 years of accumulated assumptions about the x86 exception table format. While at it, this tree also cleans up various other aspects of exception handling, such as early(er) exception handling for rdmsr_safe() et al. All in one, as the result of these changes the x86 exception code is now pretty nice and modern.
