2014-07-13parisc: fix fanotify_mark() syscall on 32bit compat kernelHelge Deller2-1/+11
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().

2014-07-11ext4: revert commit which was causing fs corruption after journal replaysTheodore Ts'o1-27/+24
Commit 007649375f6af2 ("ext4: initialize multi-block allocator before checking block descriptors") causes the block group descriptor's count of the number of free blocks to become inconsistent with the number of free blocks in the allocation bitmap. This is a harmless form of fs corruption, but it causes the kernel to potentially remount the file system read-only, or to panic, depending on the file systems's error behavior. Thanks to Eric Whitney for his tireless work to reproduce and to find the guilty commit.

2014-07-11powerpc/perf: Never program book3s PMCs with values >= 0x80000000Anton Blanchard1-1/+16
We are seeing a lot of PMU warnings on POWER8: Can't find PMC that caused IRQ Looking closer, the active PMC is 0 at this point and we took a PMU exception on the transition from negative to 0. Some versions of POWER8 have an issue where they edge detect and not level detect PMC overflows. A number of places program the PMC with (0x80000000 - period_left), where period_left can be negative. We can either fix all of these or just ensure that period_left is always >= 1. This patch takes the second option.

Fix the problem by disabling RELOCATABLE for COMPILE_TEST builds instead.

2014-07-11powerpc/perf: Clear MMCR2 when enabling PMUJoel Stanley1-0/+3
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. This is okay, however the user of the PMU needs to ensure that it is in a defined state when it starts using it.

2014-07-11powerpc/kvm: Remove redundant save of SIER AND MMCR2Joel Stanley1-5/+0
These two registers are already saved in the block above. Aside from being unnecessary, by the time we get down to the second save location r8 no longer contains MMCR2, so we are clobbering the saved value with PMC5. MMCR2 primarily consists of counter freeze bits. So restoring the value of PMC5 into MMCR2 will most likely have the effect of freezing counters.
