As the new x86 CPU bootup printout format code maintainer, I am taking immediate action to improve and clean (and thus indulge my OCD) the reporting of the cores when coming up online. Fix padding to a right-hand alignment, cleanup code and bind reporting width to the max number of supported CPUs on the system, like this: [ 0.074509] smpboot: Booting Node 0, Processors: #1 #2 #3 #4 #5 torvalds#6 torvalds#7 OK [ 0.644008] smpboot: Booting Node 1, Processors: torvalds#8 torvalds#9 torvalds#10 torvalds#11 torvalds#12 torvalds#13 torvalds#14 torvalds#15 OK [ 1.245006] smpboot: Booting Node 2, Processors: torvalds#16 torvalds#17 torvalds#18 torvalds#19 torvalds#20 torvalds#21 torvalds#22 torvalds#23 OK [ 1.864005] smpboot: Booting Node 3, Processors: torvalds#24 torvalds#25 torvalds#26 torvalds#27 torvalds#28 torvalds#29 torvalds#30 torvalds#31 OK [ 2.489005] smpboot: Booting Node 4, Processors: torvalds#32 torvalds#33 torvalds#34 torvalds#35 torvalds#36 torvalds#37 torvalds#38 torvalds#39 OK [ 3.093005] smpboot: Booting Node 5, Processors: torvalds#40 torvalds#41 torvalds#42 torvalds#43 torvalds#44 torvalds#45 torvalds#46 torvalds#47 OK [ 3.698005] smpboot: Booting Node 6, Processors: torvalds#48 torvalds#49 torvalds#50 torvalds#51 #52 #53 torvalds#54 torvalds#55 OK [ 4.304005] smpboot: Booting Node 7, Processors: torvalds#56 torvalds#57 #58 torvalds#59 torvalds#60 torvalds#61 torvalds#62 torvalds#63 OK [ 4.961413] Brought up 64 CPUs and this: [ 0.072367] smpboot: Booting Node 0, Processors: #1 #2 #3 #4 #5 torvalds#6 torvalds#7 OK [ 0.686329] Brought up 8 CPUs Signed-off-by: Borislav Petkov <[email protected]> Cc: Libin <[email protected]> Cc: [email protected] Cc: [email protected] Cc: [email protected] Cc: [email protected] Link: http://lkml.kernel.org/r/[email protected] Signed-off-by: Ingo Molnar <[email protected]>

Which is totally silly as new->user_ns is NULL (as is every other field in new except session_keyring at that point). The intent is clearly to copy all of the fields from old to new so copy old->user_ns into into new->user_ns.

The __this_cpu_read() function produces better code than does per_cpu_ptr() on both ARM and x86.

commit 1e77d0a upstream. Till reported that the spurious interrupt detection of threaded interrupts is broken in two ways: - note_interrupt() is called for each action thread of a shared interrupt line. That's wrong as we are only interested whether none of the device drivers felt responsible for the interrupt, but by calling multiple times for a single interrupt line we account IRQ_NONE even if one of the drivers felt responsible. - note_interrupt() when called from the thread handler is not serialized. That leaves the members of irq_desc which are used for the spurious detection unprotected. To solve this we need to defer the spurious detection of a threaded interrupt to the next hardware interrupt context where we have implicit serialization. If note_interrupt is called with action_ret == IRQ_WAKE_THREAD, we check whether the previous interrupt requested a deferred check. If not, we request a deferred check for the next hardware interrupt and return. If set, we check whether one of the interrupt threads signaled success. Depending on this information we feed the result into the spurious detector.

commit cd9e83e upstream. At least the Dell Vostro 5470 elantech *clickpad* reports right button clicks when clicked in the right bottom area: https://bugzilla.redhat.com/show_bug.cgi?id=1103528 This is different from how (elantech) clickpads normally operate, normally no matter where the user clicks on the pad the pad always reports a left button event, since there is only 1 hardware button beneath the path. It looks like Dell has put 2 buttons under the pad, one under each bottom corner, causing this. Since this however still clearly is a real clickpad hardware-wise, we still want to report it as such to userspace, so that things like finger movement in the bottom area can be properly ignored as it should be on clickpads. So deal with this weirdness by simply mapping a right click to a left click on elantech clickpads. As an added advantage this is something which we can simply do on all elantech clickpads, so no need to add special quirks for this weird model.

… modules commit 91ad11d upstream. On MIPS calls to _mcount in modules generate 2 instructions to load the _mcount address (and therefore 2 relocations). The mcount_loc table should only reference the first of these, so the second is filtered out by checking the relocation offset and ignoring ones that immediately follow the previous one seen. However if a module has an _mcount call at offset 0, the second relocation would not be filtered out due to old_r_offset == 0 being taken to mean that the current relocation is the first one seen, and both would end up in the mcount_loc table. This results in ftrace_make_nop() patching both (adjacent) instructions to branches over the _mcount call sequence like so: 0xffffffffc08a8000: 04 00 00 10 b 0xffffffffc08a8014 0xffffffffc08a8004: 04 00 00 10 b 0xffffffffc08a8018 0xffffffffc08a8008: 2d 08 e0 03 move at,ra ... The second branch is in the delay slot of the first, which is defined to be unpredictable - on the platform on which this bug was encountered, it triggers a reserved instruction exception. Fix by initializing old_r_offset to ~0 and using that instead of 0 to determine whether the current relocation is the first seen.

commit ab6c15b upstream. Previously, the lower limit for the MIPS SC initialization loop was set incorrectly allowing one extra loop leading to writes beyond the MSC ioremap'd space. More precisely, the value of the 'imp' in the last loop increased beyond the msc_irqmap_t boundaries and as a result of which, the 'n' variable was loaded with an incorrect value. This value was used later on to calculate the offset in the MSC01_IC_SUP which led to random crashes like the following one: CPU 0 Unable to handle kernel paging request at virtual address e75c0200, epc == 8058dba4, ra == 8058db90 [...] Call Trace: [<8058dba4>] init_msc_irqs+0x104/0x154 [<8058b5bc>] arch_init_irq+0xd8/0x154 [<805897b0>] start_kernel+0x220/0x36c Kernel panic - not syncing: Attempted to kill the idle task!

Thus, I think this assertion is wrong and should be removed. Suppose there are two clean znodes and one dirty znode in TNC. So the per-filesystem atomic_t @clean_zn_cnt is (2). If commit start, dirty_znode is set to COW_ZNODE in get_znodes_to_commit() in case of potentially ops on this znode. We clear COW bit and DIRTY bit in write_index() without @tnc_mutex locked. We don't increase @clean_zn_cnt in this place. As the comments in write_index() shows, if another process hold @tnc_mutex and dirty this znode after we clean it, @clean_zn_cnt would be decreased to (1). We will increase @clean_zn_cnt to (2) with @tnc_mutex locked in free_obsolete_znodes() to keep it right. If shrink_tnc() performs between decrease and increase, it will release other 2 clean znodes it holds and found @clean_zn_cnt is less than zero (1 - 2 = -1), then hit the assertion. Because free_obsolete_znodes() will soon correct @clean_zn_cnt and no harm to fs in this case, I think this assertion could be removed. 2 clean zondes and 1 dirty znode, @clean_zn_cnt == 2 Thread A (commit) Thread B (write or others) Thread C (shrinker) ->write_index ->clear_bit(DIRTY_NODE) ->clear_bit(COW_ZNODE) @clean_zn_cnt == 2 ->mutex_locked(&tnc_mutex) ->dirty_cow_znode ->!ubifs_zn_cow(znode) ->!test_and_set_bit(DIRTY_NODE) ->atomic_dec(&clean_zn_cnt) ->mutex_unlocked(&tnc_mutex) @clean_zn_cnt == 1 ->mutex_locked(&tnc_mutex) ->shrink_tnc ->destroy_tnc_subtree ->atomic_sub(&clean_zn_cnt, 2) ->ubifs_assert <- hit ->mutex_unlocked(&tnc_mutex) @clean_zn_cnt == -1 ->mutex_lock(&tnc_mutex) ->free_obsolete_znodes ->atomic_inc(&clean_zn_cnt) ->mutux_unlock(&tnc_mutex) @clean_zn_cnt == 0 (correct after shrink) Signed-off-by: hujianyang <[email protected]> Signed-off-by: Artem Bityutskiy <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>

Fix niu_try_msix() to not cause a fatal trap on sparc systems. Set PCI_DEV_FLAGS_MSIX_TOUCH_ENTRY_DATA_FIRST on the struct pci_dev to work around a bug in the hardware or firmware. For each vector entry in the msix table, niu chips will cause a fatal trap if any registers in that entry are read before that entries' ENTRY_DATA register is written to.

Fix niu_try_msix() to not cause a fatal trap on sparc systems. Set PCI_DEV_FLAGS_MSIX_TOUCH_ENTRY_DATA_FIRST on the struct pci_dev to work around a bug in the hardware or firmware. For each vector entry in the msix table, niu chips will cause a fatal trap if any registers in that entry are read before that entries' ENTRY_DATA register is written to. Testing indicates writes to other registers are not sufficient to prevent the fatal trap, however the value does not appear to matter. This only needs to happen once after power up, so simply rebooting into a kernel lacking this fix will NOT cause the trap.
