2016-01-14modpost: don't add a trailing wildcard for OF module aliasesJavier Martinez Canillas1-2/+1
Commit ac551828993e ("modpost: i2c aliases need no trailing wildcard") removed the wildcard at the end of the I2C module aliases because I2C devices have no IDs so the aliases are just arbitrary device names. This is also true for OF modaliases since a compatible string is used to define a specific IP hardware block. So the modalias should match a specific compatible string and not attempt to match a compatible string whose name matches the beginning of another one. For example, the following driver module: $ modinfo cros_ec_keyb | grep alias alias: platform:cros-ec-keyb alias: of:N*T*Cgoogle,cros-ec-keyb* will be tried to be loaded for an alias of:N*T*Cgoogle,cros-ec-keyb-v2 but there could be a different driver that supports the device for that compatible string so it's better to remove the trailing wildcard for OF. Also, remove the word "always" from the add_wildcard() function comment since that was carried from the time where a wildcard was always added at the end of the module alias for all the devices.

2016-01-13scripts/recordmcount.pl: support data in text section on powerpcUlrich Weigand1-1/+2
If a text section starts out with a data blob before the first function start label, disassembly parsing doing in recordmcount.pl gets confused on powerpc, leading to creation of corrupted module objects. This was not a problem so far since the compiler would never create such text sections. However, this has changed with a recent change in GCC 6 to support distances of > 2GB between a function and its assoicated TOC in the ELFv2 ABI, exposing this problem. There is already code in recordmcount.pl to handle such data blobs on the sparc64 platform. This patch uses the same method to handle those on powerpc as well.

2016-01-04Fix ld-version.sh to handle large 3rd version partJames Hogan1-1/+1
The ld-version.sh script doesn't handle versions with large (>= 10) 3rd version components, because the 2nd component is only multiplied by 10 times that of the 3rd component. For example the following version string: GNU ld (Codescape GNU Tools 2015.06-05 for MIPS MTI Linux) 2.24.90 gives a bogus version number: 20000000 + 2400000 + 900000 = 23300000 Breakage, confusion and mole-whacking ensues. Increase the multipliers of the first two version components by a factor of 10 to give space for a 3rd components of up to 99, and update the sole user of ld-ifversion (MIPS VDSO) accordingly.

2015-12-16ftrace/scripts: Have recordmcount copy the object fileSteven Rostedt (Red Hat)1-35/+110
Russell King found that he had weird side effects when compiling the kernel with hard linked ccache. The reason was that recordmcount modified the kernel in place via mmap, and when a file gets modified twice by recordmcount, it will complain about it. To fix this issue, Russell wrote a patch that checked if the file was hard linked more than once and would unlink it if it was. Linus Torvalds was not happy with the fact that recordmcount does this in place modification. Instead of doing the unlink only if the file has two or more hard links, it does the unlink all the time. In otherwords, it always does a copy if it changed something. That is, it does the write out if a change was made.

For example a simple input like /** * enum flags - test flags * @flag1: first flag * @flag2: second flag */ enum flags { flag1 = BIT(0), #ifdef SECOND_FLAG flag2 = BIT(1), #endif }; resulted in parsing warnings like warning: Enum value '#ifdef SECOND_FLAG;flag2 = BIT(1)' not described in enum 'flags' warning: Enum value '#endif;' not described in enum 'flags' Signed-off-by: Conchúr Navid <conchur@web.de> Signed-off-by: Jonathan Corbet <corbet@lwn.net>
2015-11-20kernel-doc: Fix stripping of #define in enumsConchúr Navid1-1/+1
The regex to strip single line #define's in enumerations depends on the fact that the defines are still stored on separate lines. But the surrounding code already removed newlines and replaced them with semicolons. For example a simple input like /** * enum flags - test flags * @flag1: first flag * @flag2: second flag * @flag3: third flag * @flag4: fourth flag */ enum flags { flag1 = BIT(0), flag2 = BIT(1), #define flags_small (flag1 | flag2) flag3 = BIT(2), flag4 = BIT(3), #define flags_big (flag2 | flag3) }; resulted in parsing warnings like warning: Enum value '#define flags_small (flag1 | flag2);flag3 = BIT(2)' not described in enum 'flags' warning: Enum value '#define flags_big (flag2 | flag3);' not described in enum 'flags' Signed-off-by: Conchúr Navid <conchur@web.de> Signed-off-by: Jonathan Corbet <corbet@lwn.net>

Many flag options are boolean and support both a positive and a negative invocation from the command line. Some of these are even mentioned by example (e.g., --nogit is mentioned as a default option), but they aren't explicitly mentioned in the list of options. It happens that some of these are pretty important, as they are default-on, and to turn them off, you have to know about the --no-foo version. Rather than clutter the whole help text with bracketed '--[no]foo', let's just mention the general rule, a la 'man gcc'.

You can now filter function tracing to several modules. # echo '*:mod:*snd*' > set_ftrace_filter (Dmitry Safonov) - Tracer specific options are now visible even when the tracer is not active. It was rather annoying that you can only see and modify tracer options after enabling the tracer. Now they are in the options/ directory even when the tracer is not active. Although they are still only visible when the tracer is active in the trace_options file. - Trace options are now per instance (although some of the tracer specific options are global) - New tracefs file: set_event_pid.

Pull sound updates from Takashi Iwai: "Here is the first batch of updates for sound system on 4.4-rc1. Again at this time, the update looks fairly calm; no big changes in either ALSA core or ASoC infrastructures, rather all small cleanups, in addition to the new stuff as usual. The biggest changes are about Firewire sound devices. It gained lots of new device support, and MIDI functionality. Also there are updates for a few still working-in-progress stuff (topology API and ASoC skylake), too. But overall, this update should give no big surprise. Some highlights are below: Core: - A few more Kconfig items for tinification; it's marked as EXPERT, so normal user should't be bothered :) - Refactoring with a new PCM hw_constraint helper - Removal of unused transfer_ack_{begin,end} PCM callbacks Firewire: - Restructuring of code subtree, lots of refactoring - Support AMDTP variants - New driver for Digidesign 002/003 family - Adds support for TASCAM FireOne to ALSA OXFW driver - Add MIDI support to TASCAM and Digi00x devices HD-Audio: - Automated modalias generation for codec drivers, finally - Improvement on heuristics for setting mixer name - A few fixes for longstanding bugs on Creative CA0132 cards - Addition of audio rate callback with i915 communication - Fix suspend issue on recent Dell XPS - Intel Lewisburg controller support ASoC: - Updates to the topology userspace interface - Big updates to the Renesas support (rcar) - More updates for supporting Intel Sky Lake systems - New drivers for Asahi Kasei Microdevices AK4613, Allwinnner A10, Cirrus Logic WM8998, Dialog DA7219, Nuvoton NAU8825, Rockchip S/PDIF, and Atmel class D amplifier USB-Audio: - A fix for newer Roland MIDI devices - Quirks and workarounds for Zoom R16/24 device Misc: - A few fixes for some old Cirrus CS46xx PCI sound boards - Yet another fixes for some old ESS Maestro3 PCI sound boards" * tag 'sound-4.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (330 commits) ALSA: hda - Add Intel Lewisburg device IDs Audio ALSA: hda - Apply pin fixup for HP ProBook 6550b ALSA: hda - Fix lost 4k BDL boundary workaround ALSA: maestro3: Fix Allegro mute until master volume/mute is touched ALSA: maestro3: Enable docking support for Dell Latitude C810 ALSA: firewire-digi00x: add another rawmidi character device for MIDI control ports ALSA: firewire-digi00x: add MIDI operations for MIDI control port ALSA: firewire-digi00x: rename identifiers of MIDI operation for physical ports ALSA: cs46xx: Fix suspend for all channels ALSA: cs46xx: Fix Duplicate front for CS4294 and CS4298 codecs ALSA: DocBook: Add soc-ops.c and soc-compress.c ALSA: hda - Add / fix kernel doc comments ALSA: Constify ratden/ratnum constraints ALSA: hda - Disable 64bit address for Creative HDA controllers ALSA: hda/realtek - Dell XPS one ALC3260 speaker no sound after resume back ALSA: hda/ca0132 - Convert leftover pr_info() and pr_err() ASoC: fsl: Use #ifdef instead of #if for CONFIG_PM_SLEEP ASoC: rt5645: Sort the order for register bit defines ASoC: dwc: add check for master/slave format ASoC: rt5645: Add the HWEQ for the speaker output ...

Pull arm64 updates from Catalin Marinas: - "genirq: Introduce generic irq migration for cpu hotunplugged" patch merged from tip/irq/for-arm to allow the arm64-specific part to be upstreamed via the arm64 tree - CPU feature detection reworked to cope with heterogeneous systems where CPUs may not have exactly the same features. The features reported by the kernel via internal data structures or ELF_HWCAP are delayed until all the CPUs are up (and before user space starts) - Support for 16KB pages, with the additional bonus of a 36-bit VA space, though the latter only depending on EXPERT - Implement native {relaxed, acquire, release} atomics for arm64 - New ASID allocation algorithm which avoids IPI on roll-over, together with TLB invalidation optimisations (using local vs global where feasible) - KASan support for arm64 - EFI_STUB clean-up and isolation for the kernel proper (required by KASan) - copy_{to,from,in}_user optimisations (sharing the memcpy template) - perf: moving arm64 to the arm32/64 shared PMU framework - L1_CACHE_BYTES increased to 128 to accommodate Cavium hardware - Support for the contiguous PTE hint on kernel mapping (16 consecutive entries may be able to use a single TLB entry) - Generic CONFIG_HZ now used on arm64 - defconfig updates * tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: (91 commits) arm64/efi: fix libstub build under CONFIG_MODVERSIONS ARM64: Enable multi-core scheduler support by default arm64/efi: move arm64 specific stub C code to libstub arm64: page-align sections for DEBUG_RODATA arm64: Fix build with CONFIG_ZONE_DMA=n arm64: Fix compat register mappings arm64: Increase the max granular size arm64: remove bogus TASK_SIZE_64 check arm64: make Timer Interrupt Frequency selectable arm64/mm: use PAGE_ALIGNED instead of IS_ALIGNED arm64: cachetype: fix definitions of ICACHEF_* flags arm64: cpufeature: declare enable_cpu_capabilities as static genirq: Make the cpuhotplug migration code less noisy arm64: Constify hwcap name string arrays arm64/kvm: Make use of the system wide safe values arm64/debug: Make use of the system wide safe value arm64: Move FP/ASIMD hwcap handling to common code arm64/HWCAP: Use system wide safe values arm64/capabilities: Make use of system wide safe value arm64: Delay cpu feature capability checks ...
2015-11-03recordmcount: arm64: Replace the ignored mcount call into nopLi Bin1-1/+23
By now, the recordmcount only records the function that in following sections: .text/.ref.text/.sched.text/.spinlock.text/.irqentry.text/ .kprobes.text/.text.unlikely For the function that not in these sections, the call mcount will be in place and not be replaced when kernel boot up. And it will bring performance overhead, such as do_mem_abort (in .exception.text section). This patch make the call mcount to nop for this case in recordmcount.
