2015-08-13x86/mce: Reenable CMCI banks when swiching back to interrupt modeXie XiuQi
Zhang Liguang reported the following issue: 1) System detects a CMCI storm on the current CPU. 2) Kernel disables the CMCI interrupt on banks owned by the current CPU and switches to poll mode 3) After the CMCI storm subsides, kernel switches back to interrupt mode 4) We expect the system to reenable the CMCI interrupt on banks owned by the current CPU mce_intel_adjust_timer |-> cmci_reenable |-> cmci_discover # owned banks are ignored here static void cmci_discover(int banks) ... for (i = 0; i < banks; i++) { ... if (test_bit(i, owned)) # ownd banks is ignore here continue; So convert cmci_storm_disable_banks() to cmci_toggle_interrupt_mode() which controls whether to enable or disable CMCI interrupts with its argument. NB: We cannot clear the owned bit because the banks won't be polled, otherwise. See: 27f6c573e0f7 ("x86, CMCI: Add proper detection of end of CMCI storms") for more info.

Printing in MCE context is a no-no, currently, as printk() is not NMI-safe. If some of the notifiers on the MCE chain call do so, we may deadlock.

2015-08-13x86/mce: Provide a lockless memory pool to save error recordsChen, Gong
printk() is not safe to use in MCE context. Add a lockless memory allocator pool to save error records in MCE context. Those records will be issued later, in a printk-safe context. The idea is inspired by the APEI/GHES driver. We're very conservative and allocate only two pages for it but since we're going to use those pages throughout the system's lifetime, we allocate them statically to avoid early boot time allocation woes.

2015-08-10HID: wacom: Report correct device resolution when using the wireless adapaterJason Gerecke
The 'wacom_wireless_work' function does not recalculate the tablet's resolution, causing the value contained in the 'features' struct to always be reported to userspace. This value is valid only for the pen interface, meaning that the value will be incorrect for the touchpad (if present). This in particular causes problems for libinput which relies on the reported resolution being correct. This patch adds the necessary calls to recalculate the resolution for each interface. This requires a little bit of code shuffling since both the 'wacom_set_default_phy' and 'wacom_calculate_res' are declared below their new first point of use in 'wacom_wireless_work'.

It was possible for a synchronous update of the RX index in the error case to get ahead of the asynchronous RX index update in the normal case. Change the RX processing to preserve an RX completion order. There were two error cases. First, if a buffer is not present to receive data, there would be no queue entry to preserve the RX completion order. Instead of dropping the RX frame, leave the RX frame in the ring. Schedule RX processing when RX entries are enqueued, in case there are RX frames waiting in the ring to be received. Second, if a buffer is too small to receive data, drop the frame in the ring, mark the RX entry as done, and indicate the error in the RX entry length. Check for a negative length in the receive callback in ntb_netdev, and count occurrences as rx_length_errors.

Pull MIPS fixes from Ralf Baechle: "Another round of MIPS fixes for 4.2. No area does particularly stand out but we have a two unpleasant ones: - Kernel ptes are marked with a global bit which allows the kernel to share kernel TLB entries between all processes. For this to work both entries of an adjacent even/odd pte pair need to have the global bit set. There has been a subtle race in setting the other entry's global bit since ~ 2000 but it take particularly pathological workloads that essentially do mostly vmalloc/vfree to trigger this. This pull request fixes the 64-bit case but leaves the case of 32 bit CPUs with 64 bit ptes unsolved for now. The unfixed cases affect hardware that is not available in the field yet. - Instruction emulation requires loading instructions from user space but the current fast but simplistic approach will fail on pages that are PROT_EXEC but !PROT_READ. For this reason we temporarily do not permit this permission and will map pages with PROT_EXEC | PROT_READ.
