1c48a17 James Hogan 20 May 2016, 22:28:38 UTC MIPS: Add missing VZ accessor microMIPS encodings Toolchains may be used which support microMIPS but not VZ instructions (i.e. binutis 2.22 & 2.23), so extend the explicitly encoded versions of the guest COP0 register & guest TLB access macros to support microMIPS encodings too, using the new macros. This prevents non-microMIPS instructions being executed in microMIPS mode during CPU probe on cores supporting VZ (e.g. M5150), which cause reserved instruction exceptions early during boot. Fixes: bad50d79255a ("MIPS: Fix VZ probe gas errors with binutils <2.24") Signed-off-by: James Hogan <james.hogan@imgtec.com> Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/13311/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org> 28 May 2016, 10:35:10 UTC
0dfa1c1 James Hogan 20 May 2016, 22:28:37 UTC MIPS: Add inline asm encoding helpers To allow simplification of macros which use inline assembly to explicitly encode instructions, add a few simple abstractions to mipsregs.h which expand to specific microMIPS or normal MIPS encodings depending on what type of kernel is being built: _ASM_INSN_IF_MIPS(_enc) : Emit a 32bit MIPS instruction if microMIPS is not enabled. _ASM_INSN32_IF_MM(_enc) : Emit a 32bit microMIPS instruction if enabled. _ASM_INSN16_IF_MM(_enc) : Emit a 16bit microMIPS instruction if enabled. The macros can be used one after another since the MIPS / microMIPS macros are mutually exclusive, for example: __asm__ __volatile__( ".set push\n\t" ".set noat\n\t" "# mfgc0 $1, $%1, %2\n\t" _ASM_INSN_IF_MIPS(0x40610000 | %1 << 11 | %2) _ASM_INSN32_IF_MM(0x002004fc | %1 << 16 | %2 << 11) "move %0, $1\n\t" ".set pop" : "=r" (__res) : "i" (source), "i" (sel)); Signed-off-by: James Hogan <james.hogan@imgtec.com> Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/13310/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org> 28 May 2016, 10:35:09 UTC

1ff5fa3 Cameron Gutman 27 May 2016, 23:23:50 UTC Input: xpad - prevent spurious input from wired Xbox 360 controllers After initially connecting a wired Xbox 360 controller or sending it a command to change LEDs, a status/response packet is interpreted as controller input. This causes the state of buttons represented in byte 2 of the controller data packet to be incorrect until the next valid input packet. Wireless Xbox 360 controllers are not affected. Writing a new value to the LED device while holding the Start button and running jstest is sufficient to reproduce this bug. An event will come through with the Start button released. Xboxdrv also won't attempt to read controller input from a packet where byte 0 is non-zero. It also checks that byte 1 is 0x14, but that value differs between wired and wireless controllers and this code is shared by both. I think just checking byte 0 is enough to eliminate unwanted packets. The following are some examples of 3-byte status packets I saw: 01 03 02 02 03 00 03 03 03 08 03 00 Signed-off-by: Cameron Gutman <aicommander@gmail.com> Signed-off-by: Pavel Rojtberg <rojtberg@gmail.com> Cc: stable@vger.kernel.org Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com> 27 May 2016, 23:32:47 UTC

5d22fc2 Linus Torvalds 27 May 2016, 22:57:31 UTC mm: remove more IS_ERR_VALUE abuses The do_brk() and vm_brk() return value was "unsigned long" and returned the starting address on success, and an error value on failure. The reasons are entirely historical, and go back to it basically behaving like the mmap() interface does. However, nobody actually wanted that interface, and it causes totally pointless IS_ERR_VALUE() confusion. What every single caller actually wants is just the simpler integer return of zero for success and negative error number on failure. So just convert to that much clearer and more common calling convention, and get rid of all the IS_ERR_VALUE() uses wrt vm_brk().

287980e Arnd Bergmann 27 May 2016, 21:23:25 UTC remove lots of IS_ERR_VALUE abuses Most users of IS_ERR_VALUE() in the kernel are wrong, as they pass an 'int' into a function that takes an 'unsigned long' argument. This happens to work because the type is sign-extended on 64-bit architectures before it gets converted into an unsigned type. However, anything that passes an 'unsigned short' or 'unsigned int' argument into IS_ERR_VALUE() is guaranteed to be broken, as are 8-bit integers and types that are wider than 'unsigned long'. Andrzej Hajda has already fixed a lot of the worst abusers that were causing actual bugs, but it would be nice to prevent any users that are not passing 'unsigned long' arguments. This patch changes all users of IS_ERR_VALUE() that I could find on 32-bit ARM randconfig builds and x86 allmodconfig. For the moment, this doesn't change the definition of IS_ERR_VALUE() because there are probably still architecture specific users elsewhere. Almost all the warnings I got are for files that are better off using 'if (err)' or 'if (err < 0)'. The only legitimate user I could find that we get a warning for is the (32-bit only) freescale fman driver, so I did not remove the IS_ERR_VALUE() there but changed the type to 'unsigned long'. For 9pfs, I just worked around one user whose calling conventions are so obscure that I did not dare change the behavior. I was using this definition for testing: #define IS_ERR_VALUE(x) ((unsigned long*)NULL == (typeof (x)*)NULL && \ unlikely((unsigned long long)(x) >= (unsigned long long)(typeof(x))-MAX_ERRNO)) which ends up making all 16-bit or wider types work correctly with the most plausible interpretation of what IS_ERR_VALUE() was supposed to return according to its users, but also causes a compile-time warning for any users that do not pass an 'unsigned long' argument. I suggested this approach earlier this year, but back then we ended up deciding to just fix the users that are obviously broken. After the initial warning that caused me to get involved in the discussion (fs/gfs2/dir.c) showed up again in the mainline kernel, Linus asked me to send the whole thing again.

Use early_pfn_to_nid() instead of pfn_to_nid() so that page extension could be still used early even though CONFIG_ DEFERRED_STRUCT_PAGE_INIT is enabled and catch early page allocation call sites. Suggested by Joonsoo Kim [1], this fix basically undoes the change introduced by commit b8f1a75d61d840 ("mm: call page_ext_init() after all struct pages are initialized") and fixes the same problem with a better approach.

9ecd10b Eryu Guan 27 May 2016, 21:27:18 UTC direct-io: fix direct write stale data exposure from concurrent buffered read Currently direct writes inside i_size on a DIO_SKIP_HOLES filesystem are not allowed to allocate blocks(get_more_blocks() sets 'create' to 0 before calling get_block() callback), if it's a sparse file, direct writes fall back to buffered writes to avoid stale data exposure from concurrent buffered read. But there're two cases that can result in stale data exposure are not correctly detected. 1. The detection for "writing inside i_size" is not sufficient, writes can be treated as "extending writes" wrongly. For example, direct write 1FSB (file system block) to a 1FSB sparse file on ext2/3/4, starting from offset 0, in this case it's writing inside i_size, but 'create' is non-zero, because 'block_in_file' and '(i_size_read(inode) >> blkbits' are both zero. 2. Direct writes starting from or beyong i_size (not inside i_size) also could trigger block allocation and expose stale data. For example, consider a sparse file with i_size of 2k, and a write to offset 2k or 3k into the file, with a filesystem block size of 4k. (Thanks to Jeff Moyer for pointing this case out in his review.) The first problem can be demostrated by running ltp-aiodio test ADSP045 many times. When testing on extN filesystems, I see test failures occasionally, buffered read could read non-zero (stale) data. ADSP045: dio_sparse -a 4k -w 4k -s 2k -n 1 dio_sparse 0 TINFO : Dirtying free blocks dio_sparse 0 TINFO : Starting I/O tests non zero buffer at buf[0] => 0xffffffaa,ffffffaa,ffffffaa,ffffffaa non-zero read at offset 0 dio_sparse 0 TINFO : Killing childrens(s) dio_sparse 1 TFAIL : dio_sparse.c:191: 1 children(s) exited abnormally The second problem can also be reproduced easily by a hacked dio_sparse program, which accepts an option to specify the write offset. What we should really do is to disable block allocation for writes that could result in filling holes inside i_size.

e0cbb79 Junxiao Bi 27 May 2016, 21:26:58 UTC ocfs2: o2hb: add negotiate timer This series of patches is to fix the issue that when storage down, all nodes will fence self due to write timeout. With this patch set, all nodes will keep going until storage back online, except if the following issue happens, then all nodes will do as before to fence self. 1. io error got 2. network between nodes down 3. nodes panic This patch (of 6): When storage down, all nodes will fence self due to write timeout. The negotiate timer is designed to avoid this, with it node will wait until storage up again. Negotiate timer working in the following way: 1. The timer expires before write timeout timer, its timeout is half of write timeout now. It is re-queued along with write timeout timer. If expires, it will send NEGO_TIMEOUT message to master node(node with lowest node number). This message does nothing but marks a bit in a bitmap recording which nodes are negotiating timeout on master node. 2. If storage down, nodes will send this message to master node, then when master node finds its bitmap including all online nodes, it sends NEGO_APPROVL message to all nodes one by one, this message will re-queue write timeout timer and negotiate timer. For any node doesn't receive this message or meets some issue when handling this message, it will be fenced. If storage up at any time, o2hb_thread will run and re-queue all the timer, nothing will be affected by these two steps.

b740d2e Rajneesh Bhardwaj 26 May 2016, 09:11:19 UTC platform/x86: Add PMC Driver for Intel Core SoC This patch adds the Power Management Controller driver as a PCI driver for Intel Core SoC architecture. This driver can utilize debugging capabilities and supported features as exposed by the Power Management Controller. Please refer to the below specification for more details on PMC features. http://www.intel.in/content/www/in/en/chipsets/100-series-chipset-datasheet-vol-2.html The current version of this driver exposes SLP_S0_RESIDENCY counter. This counter can be used for detecting fragile SLP_S0 signal related failures and take corrective actions when PCH SLP_S0 signal is not asserted after kernel freeze as part of suspend to idle flow (echo freeze > /sys/power/state). Intel Platform Controller Hub (PCH) asserts SLP_S0 signal when it detects favorable conditions to enter its low power mode. As a pre-requisite the SoC should be in deepest possible Package C-State and devices should be in low power mode. For example, on Skylake SoC the deepest Package C-State is Package C10 or PC10. Suspend to idle flow generally leads to PC10 state but PC10 state may not be sufficient for realizing the platform wide power potential which SLP_S0 signal assertion can provide. SLP_S0 signal is often connected to the Embedded Controller (EC) and the Power Management IC (PMIC) for other platform power management related optimizations. In general, SLP_S0 assertion == PC10 + PCH low power mode + ModPhy Lanes power gated + PLL Idle. As part of this driver, a mechanism to read the SLP_S0_RESIDENCY is exposed as an API and also debugfs features are added to indicate SLP_S0 signal assertion residency in microseconds. echo freeze > /sys/power/state wake the system cat /sys/kernel/debug/pmc_core/slp_s0_residency_usec Signed-off-by: Rajneesh Bhardwaj <rajneesh.bhardwaj@intel.com> Signed-off-by: Vishwanath Somayaji <vishwanath.somayaji@intel.com> Reviewed-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: Darren Hart <dvhart@linux.intel.com> 27 May 2016, 18:47:56 UTC

aca234f Oleksij Rempel 01 April 2016, 11:35:21 UTC asus-wmi: provide access to ALS control Asus Zenbook ux31a is providing ACPI0008 interface for ALS (Ambient Light Sensor), which is accessible for OS => Win 7. This sensor can be used with iio/acpi-als driver. Since it is disabled by default, we should use asus-wmi interface to enable it.

2d98e0b Arnd Bergmann 09 May 2016, 21:49:21 UTC ideapad-laptop: add a new WMI string for ESC key My patch to the ideapad-laptop driver to get the ESC key working on the Yoga 1170 (Yoga 3) failed to do the same for the following model, the Lenovo Yoga 700. Denis Gordienko managed to get it working by adding another GUID for the new WMI interface. I have adapted his patch to normal coding style and simplified it a bit for inclusion, but this patch is currently untested.

eb4606e Takashi Iwai 27 May 2016, 15:16:53 UTC Merge tag 'asoc-v4.7-2' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus ASoC: Updates for v4.7 part 2 Really sorry about this late pull request. It looks like at the time I sent my pull request for v4.7 there was some conflict or other issue which caused my script to stop merging the ASoC branches at some point after the HDMI changes. It's all specific driver updates, including: - New drivers for MAX98371 and TAS5720. - SPI support for TLV320AIC32x4. - TDM support for STI Uniperf IPs. This code should all have been in -next prior to the merge window apart from some fixes, it dropped out on the 18th. 27 May 2016, 15:16:53 UTC
