The other two patches are trivial and remove unused headers, #includes and adds the serial ports of the fastest C8000 workstation to the parisc-kernel internal hardware database" * 'parisc-3.16-5' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux: parisc: drop unused defines and header includes parisc: fix fanotify_mark() syscall on 32bit compat kernel parisc: add serial ports of C8000/1GHz machine to hardware database | 13 July 2014, 19:02:05 UTC |

ab8a261 | Helge Deller | 10 July 2014, 16:07:17 UTC | parisc: fix fanotify_mark() syscall on 32bit compat kernel On parisc we can not use the existing compat implementation for fanotify_mark() because for the 64bit mask parameter the higher and lower 32bits are ordered differently than what the compat function expects from big endian architectures. Specifically: It finally turned out, that on hppa we end up with different assignments of parameters to kernel arguments depending on if we call the glibc wrapper function int fanotify_mark (int __fanotify_fd, unsigned int __flags, uint64_t __mask, int __dfd, const char *__pathname); or directly calling the syscall manually syscall(__NR_fanotify_mark, ...) Reason is, that the syscall() function is implemented as C-function and because we now have the sysno as first parameter in front of the other parameters the compiler will unexpectedly add an empty paramenter in front of the u64 value to ensure the correct calling alignment for 64bit values. This means, on hppa you can't simply use syscall() to call the kernel fanotify_mark() function directly, but you have to use the glibc function instead. This patch fixes the kernel in the hppa-arch specifc coding to adjust the parameters in a way as if userspace calls the glibc wrapper function fanotify_mark().

In that kernel the mce code (for i386, that is) was in transition. Ever since v2.6.32 the situation is much simpler (eg, mcelog is now needed to process events on almost all x86 machines, i386 and x86-64).

b50a6c5 | Joel Stanley | 08 July 2014, 06:38:22 UTC | powerpc/perf: Clear MMCR2 when enabling PMU On POWER8 when switching to a KVM guest we set bits in MMCR2 to freeze the PMU counters. Aside from on boot they are then never reset, resulting in stuck perf counters for any user in the guest or host. We now set MMCR2 to 0 whenever enabling the PMU, which provides a sane state for perf to use the PMU counters under either the guest or the host. This was manifesting as a bug with ppc64_cpu --frequency: $ sudo ppc64_cpu --frequency WARNING: couldn't run on cpu 0 WARNING: couldn't run on cpu 8 ... WARNING: couldn't run on cpu 144 WARNING: couldn't run on cpu 152 min: 18446744073.710 GHz (cpu -1) max: 0.000 GHz (cpu -1) avg: 0.000 GHz The command uses a perf counter to measure CPU cycles over a fixed amount of time, in order to approximate the frequency of the machine. The counters were returning zero once a guest was started, regardless of weather it was still running or had been shut down. By dumping the value of MMCR2, it was observed that once a guest is running MMCR2 is set to 1s - which stops counters from running: $ sudo sh -c 'echo p > /proc/sysrq-trigger' CPU: 0 PMU registers, ppmu = POWER8 n_counters = 6 PMC1: 5b635e38 PMC2: 00000000 PMC3: 00000000 PMC4: 00000000 PMC5: 1bf5a646 PMC6: 5793d378 PMC7: deadbeef PMC8: deadbeef MMCR0: 0000000080000000 MMCR1: 000000001e000000 MMCRA: 0000040000000000 MMCR2: fffffffffffffc00 EBBHR: 0000000000000000 EBBRR: 0000000000000000 BESCR: 0000000000000000 SIAR: 00000000000a51cc SDAR: c00000000fc40000 SIER: 0000000001000000 This is done unconditionally in book3s_hv_interrupts.S upon entering the guest, and the original value is only save/restored if the host has indicated it was using the PMU.

These interrupts are delivered during the soft irq disabled state of the cpu. A cpu cannot enter any idle state with pending interrupts because they will never be serviced until the next time the cpu is woken up by some other interrupt. Its only then that the pending interrupts are replayed. This can result in device timeouts or warnings about this cpu being stuck. This patch fixes ths issue by ensuring that cpus check for pending interrupts just before entering any idle state as long as they are not in the path of split core operations.

This behaviour is based on the SYSCLK_SYS_PWR_REG registers. E.g. SYSCLK_MFC_SYS_PWR_REG = 0x0, the parent of input clock to MFC (aclk333) gets modified to oscclk = 0x1, no change in clocks. The recommended value of SYSCLK_SYS_PWR_REG before power gating any domain is 0x0. So we must also restore the clocks while powering on a domain everytime. This patch adds the framework for getting the required mux and parent clocks through a power domain device node. With this patch, while powering off a domain, parent is set to oscclk and while powering back on, its re-set to the correct parent which is as per the recommended pd on/off sequence.

7a7a3b4 | Jun'ichi Nomura | 08 July 2014, 00:55:14 UTC | dm mpath: fix IO hang due to logic bug in multipath_busy Commit e80991773 ("dm mpath: push back requests instead of queueing") modified multipath_busy() to return true if !pg_ready(). pg_ready() checks the current state of the multipath device and may return false even if a new IO is needed to change the state. Bart Van Assche reported that he had multipath IO lockup when he was performing cable pull tests. Analysis showed that the multipath device had a single path group with both paths active, but that the path group itself was not active. During the multipath device state transitions 'queue_io' got set but nothing could clear it. Clearing 'queue_io' only happens in __choose_pgpath(), but it won't be called if multipath_busy() returns true due to pg_ready() returning false when 'queue_io' is set. As such the !pg_ready() check in multipath_busy() is wrong because new IO will not be sent to multipath target and the multipath state change won't happen. That results in multipath IO lockup. The intent of multipath_busy() is to avoid unnecessary cycles of dequeue + request_fn + requeue if it is known that the multipath device will requeue. Such "busy" situations would be: - path group is being activated - there is no path and the multipath is setup to requeue if no path Fix multipath_busy() to return "busy" early only for these specific situations.

acfe0ad | Mikulas Patocka | 14 June 2014, 17:44:31 UTC | dm: allocate a special workqueue for deferred device removal The commit 2c140a246dc ("dm: allow remove to be deferred") introduced a deferred removal feature for the device mapper. When this feature is used (by passing a flag DM_DEFERRED_REMOVE to DM_DEV_REMOVE_CMD ioctl) and the user tries to remove a device that is currently in use, the device will be removed automatically in the future when the last user closes it. Device mapper used the system workqueue to perform deferred removals. However, some targets (dm-raid1, dm-mpath, dm-stripe) flush work items scheduled for the system workqueue from their destructor. If the destructor itself is called from the system workqueue during deferred removal, it introduces a possible deadlock - the workqueue tries to flush itself. Fix this possible deadlock by introducing a new workqueue for deferred removals. We allocate just one workqueue for all dm targets. The ability of dm targets to process IOs isn't dependent on deferred removal of unused targets, so a deadlock due to shared workqueue isn't possible. Also, cleanup local_init() to eliminate potential for returning success on failure.

Unfortunately, that causes it to fail loading if compiled without SMP support, at least on 32 bit kernels. Kernel log shows "i8k: unable to get SMM Dell signature", and function i8k_smm is found to return -EINVAL. Testing revealed that the culprit is the missing return value check of set_cpus_allowed_ptr.

b2c0829 | Jaegeuk Kim | 30 June 2014, 09:09:55 UTC | f2fs: do checkpoint for the renamed inode If an inode is renamed, it should be registered as file_lost_pino to conduct checkpoint at f2fs_sync_file. Otherwise, the inode cannot be recovered due to no dent_mark in the following scenario. Note that, this scenario is from xfstests/322. 1. create "a" 2. fsync "a" 3. rename "a" to "b" 4. fsync "b" 5. Sudden power-cut After recovery is done, "b" should be seen. However, the result shows "a", since the recovery procedure does not enter recover_dentry due to no dent_mark. The reason is like below. - The nid of "a" is checkpointed during #2, f2fs_sync_file. - The inode page for "b" produced by #3 is written without dent_mark by sync_node_pages. So, this patch fixes this bug by assinging file_lost_pino to the "a"'s inode. If the pino is lost, f2fs_sync_file conducts checkpoint, and then recovers the latest pino and its dentry information for further recovery.
