It doesn't trim just symbols that are totally unused in-tree - it trims the symbols unused by any in-tree modules actually built. If you've done a 'make localmodconfig' and only build a hundred or so modules, it's pretty likely that your out-of-tree module will come up lacking something... Hopefully this will save the next guy from a Homer Simpson "D'oh!" moment. Link: http://lkml.kernel.org/r/10177.1469787292@turing-police.cc.vt.eduSigned-off-by:

Copy the config fragments from the AOSP common kernel android-4.4 branch. It is becoming possible to run mainline kernels with Android, but the kernel defconfigs don't work as-is and debugging missing config options is a pain. Adding the config fragments into the kernel tree, makes configuring a mainline kernel as simple as: make ARCH=arm multi_v7_defconfig android-base.config android-recommended.config The following non-upstream config options were removed: CONFIG_NETFILTER_XT_MATCH_QTAGUID CONFIG_NETFILTER_XT_MATCH_QUOTA2 CONFIG_NETFILTER_XT_MATCH_QUOTA2_LOG CONFIG_PPPOLAC CONFIG_PPPOPNS CONFIG_SECURITY_PERF_EVENTS_RESTRICT CONFIG_USB_CONFIGFS_F_MTP CONFIG_USB_CONFIGFS_F_PTP CONFIG_USB_CONFIGFS_F_ACC CONFIG_USB_CONFIGFS_F_AUDIO_SRC CONFIG_USB_CONFIGFS_UEVENT CONFIG_INPUT_KEYCHORD CONFIG_INPUT_KEYRESET Link: http://lkml.kernel.org/r/1466708235-28593-1-git-send-email-robh@kernel.orgSigned-off-by:

Doing patches with allmodconfig kernel compiled and committing stuff into local tree have unfortunate consequence: kernel version changes (as it should) leading to recompiling and relinking of several files even if they weren't touched (or interesting at all). This and "git-whatever" figuring out current version slow down compilation for no good reason. But lets face it, "allmodconfig" kernels don't care about kernel version, they are simply compile check guinea pigs. Make LOCALVERSION_AUTO depend on !COMPILE_TEST, so it doesn't sneak into allmodconfig .config. Link: http://lkml.kernel.org/r/20160707214954.GC31678@p183.telecom.bySigned-off-by:

Commit 20d8b67c ("relay: add buffer-only channels; useful for early logging") added support to use channels with no associated files. This is useful when the exact location of relay file is not known or the the parent directory of relay file is not available, while creating the channel and the logging has to start right from the boot. But there was no provision to use global mode with buffer-only channels, which is added by this patch, without modifying the interface where initially there will be a dummy invocation of create_buf_file callback through which kernel client can convey the need of a global buffer. For the use case where drivers/kernel clients want a simple interface for the userspace, which enables them to capture data/logs from relay file inorder & without any post processing, support of Global buffer mode is warranted. Modules, like i915, using relay_open() in early init would have to later register their buffer-only relays, once debugfs is available, by calling relay_late_setup_files(). Hence relay_late_setup_files() symbol also needs to be exported. Link: http://lkml.kernel.org/r/1468404563-11653-1-git-send-email-akash.goel@intel.comSigned-off-by:

sprint_symbol_no_offset() returns the string "function_name [module_name]" where [module_name] is not printed for built in kernel functions. This means that the blacklisting code will fail when comparing module function names with the extended string. This patch adds the functionality to block a module's module_init() function by finding the space in the string and truncating the comparison to that length.

Commit e93762bb ("w1: masters: omap_hdq: add support for 1-wire mode") added a statement to clear the hdq_irqstatus flags in hdq_read_byte(). If the hdq reading process is scheduled slowly or interrupts are disabled for a while the hardware read activity might already be finished on entry of hdq_read_byte(). And hdq_isr() already has set the hdq_irqstatus to 0x6 (can be seen in debug mode) denoting that both, the TXCOMPLETE and RXCOMPLETE interrupts occurred in parallel. This means there is no need to wait and the hdq_read_byte() can just read the byte from the hdq controller. By resetting hdq_irqstatus to 0 the read process is forced to be always waiting again (because the if statement always succeeds) but the hardware will not issue another RXCOMPLETE interrupt. This results in a false timeout. After such a situation the hdq bus hangs. Link: http://lkml.kernel.org/r/b724765f87ad276a69625bc19806c8c8844c4590.1469513669.git.hns@goldelico.comSigned-off-by:

Add channelized messaging driver to support native RapidIO messaging exchange between multiple senders/recipients on devices that use kernel RapidIO subsystem services. This device driver is the result of collaboration within the RapidIO.org Software Task Group (STG) between Texas Instruments, Prodrive Technologies, Nokia Networks, BAE and IDT. Additional input was received from other members of RapidIO.org. The objective was to create a character mode driver interface which exposes messaging capabilities of RapidIO endpoint devices (mports) directly to applications, in a manner that allows the numerous and varied RapidIO implementations to interoperate. This char mode device driver allows user-space applications to setup messaging communication channels using single shared RapidIO messaging mailbox. By default this driver uses RapidIO MBOX_1 (MBOX_0 is reserved for use by RIONET Ethernet emulation driver).

I hit the following issue when run trinity in my system. The kernel is 3.4 version, but mainline has the same issue. The root cause is that the segment size is too large so the kerenl spends too long trying to allocate a page. Other cases will block until the test case quits. Also, OOM conditions will occur.

kexec physical addresses are the boot-time view of the system. For certain ARM systems (such as Keystone 2), the boot view of the system does not match the kernel's view of the system: the boot view uses a special alias in the lower 4GB of the physical address space. To cater for these kinds of setups, we need to translate between the boot view physical addresses and the normal kernel view physical addresses. This patch extracts the current transation points into linux/kexec.h, and allows an architecture to override the functions. Due to the translations required, we unfortunately end up with six translation functions, which are reduced down to four that the architecture can override.

On PAE systems (eg, ARM LPAE) the vmcore note may be located above 4GB physical on 32-bit architectures, so we need a wider type than "unsigned long" here. Arrange for paddr_vmcoreinfo_note() to return a phys_addr_t, thereby allowing it to be located above 4GB. This makes no difference for kexec-tools, as they already assume a 64-bit type when reading from this file. Link: http://lkml.kernel.org/r/E1b8koK-0004HS-K9@rmk-PC.armlinux.org.ukSigned-off-by:

In general, there's no need for the "restore sigmask" flag to live in ti->flags. alpha, ia64, microblaze, powerpc, sh, sparc (64-bit only), tile, and x86 use essentially identical alternative implementations, placing the flag in ti->status. Replace those optimized implementations with an equally good common implementation that stores it in a bitfield in struct task_struct and drop the custom implementations. Additional architectures can opt in by removing their TIF_RESTORE_SIGMASK defines. Link: http://lkml.kernel.org/r/8a14321d64a28e40adfddc90e18a96c086a6d6f9.1468522723.git.luto@kernel.orgSigned-off-by:

new_insert_key only makes any sense when it's associated with a new_insert_ptr, which is initialized to NULL and changed to a buffer_head when we also initialize new_insert_key. We can key off of that to avoid the uninitialized warning. Link: http://lkml.kernel.org/r/5eca5ffb-2155-8df2-b4a2-f162f105efed@suse.comSigned-off-by:

The header file "include/linux/nilfs2_fs.h" is composed of parts for ioctl and disk format, and both are intended to be shared with user space programs. This moves them to the uapi directory "include/uapi/linux" splitting the file to "nilfs2_api.h" and "nilfs2_ondisk.h". The following minor changes are accompanied by this migration: - nilfs_direct_node struct in nilfs2/direct.h is converged to nilfs2_ondisk.h because it's an on-disk structure. - inline functions nilfs_rec_len_from_disk() and nilfs_rec_len_to_disk() are moved to nilfs2/dir.c.
