* scripts/gdb: make lx-dmesg command work (reliably)André Draszik2017-06-021-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | lx-dmesg needs access to the log_buf symbol from printk.c. Unfortunately, the symbol log_buf also exists in BPF's verifier.c and hence gdb can pick one or the other. If it happens to pick BPF's log_buf, lx-dmesg doesn't work: (gdb) lx-dmesg Python Exception <class 'gdb.MemoryError'> Cannot access memory at address 0x0: Error occurred in Python command: Cannot access memory at address 0x0 (gdb) p log_buf $15 = 0x0 Luckily, GDB has a way to deal with this, see https://sourceware.org/gdb/onlinedocs/gdb/Symbols.html (gdb) info variables ^log_buf$ All variables matching regular expression "^log_buf$": File <linux.git>/kernel/bpf/verifier.c: static char *log_buf; File <linux.git>/kernel/printk/printk.c: static char *log_buf; (gdb) p 'verifier.c'::log_buf $1 = 0x0 (gdb) p 'printk.c'::log_buf $2 = 0x811a6aa0 <__log_buf> "" (gdb) p &log_buf $3 = (char **) 0x8120fe40 <log_buf> (gdb) p &'verifier.c'::log_buf $4 = (char **) 0x8120fe40 <log_buf> (gdb) p &'printk.c'::log_buf $5 = (char **) 0x8048b7d0 <log_buf> By being explicit about the location of the symbol, we can make lx-dmesg work again.

It contains a backmerge of 4.12-rc1 since some of the downstream branches we merge had that as base; at the same time we already had merged contents before -rc1 and rebase wasn't the right solution. A mix of random smaller fixes and a few things worth pointing out: - We've started telling people to avoid cross-tree shared branches if all they're doing is picking up one or two DT-used constants from a shared include file, and instead to use the numeric values on first submission. Follow-up moving over to symbolic names are sent in right after -rc1, i.e. here. It's only a few minor patches of this type. - Linus Walleij and others are resurrecting the 'Gemini' platform, and wanted a cut-down platform-specific defconfig for it. So I picked that up for them. - Rob Herring ran 'savedefconfig' on arm64, it's a bit churny but it helps people to prepare patches since it's a pain when defconfig and current savedefconfig contents differs too much. - Devicetree additions for some pinctrl drivers for Armada that were merged this window. I'd have preferred to see those earlier but it's not a huge deail. The biggest change worth pointing out though since it's touching other parts of the tree: We added prefixes to be used when cross-including DT contents between arm64 and arm, allowing someone to #include <arm/foo.dtsi> from arm64, and likewise. As part of that, we needed arm/foo.dtsi to work on arm as well. The way I suggested this to Heiko resulted in a recursive symlink. Instead, I've now moved it out of arch/*/boot/dts/include, into a shared location under scripts/dtc. While I was at it, I consolidated so all architectures now behave the same way in this manner. Rob Herring (DT maintainer) has acked it. I cc:d most other arch maintainers but nobody seems to care much; it doesn't really affect them since functionality is unchanged for them by default" * tag 'armsoc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (29 commits) arm64: dts: rockchip: fix include reference firmware: ti_sci: fix strncat length check ARM: remove duplicate 'const' annotations' arm64: defconfig: enable options needed for QCom DB410c board arm64: defconfig: sync with savedefconfig ARM: configs: add a gemini defconfig devicetree: Move include prefixes from arch to separate directory ARM: dts: dra7: Reduce cpu thermal shutdown temperature memory: omap-gpmc: Fix debug output for access width ARM: dts: LogicPD Torpedo: Fix camera pin mux ARM: dts: omap4: enable CEC pin for Pandaboard A4 and ES ARM: dts: gta04: fix polarity of clocks for mcbsp4 ARM: dts: dra7: Add power hold and power controller properties to palmas soc: imx: add PM dependency for IMX7_PM_DOMAINS ARM: dts: imx6sx-sdb: Remove OPP override ARM: dts: imx53-qsrb: Pulldown PMIC IRQ pin soc: bcm: brcmstb: Correctly match 7435 SoC tee: add ARM_SMCCC dependency ARM: omap2+: make omap4_get_cpu1_ns_pa_addr declaration usable ARM64: dts: mediatek: configure some fixed mmc parameters ...
| * | devicetree: Move include prefixes from arch to separate directoryOlof Johansson2017-05-1816-1/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We use a directory under arch/$ARCH/boot/dts as an include path that has links outside of the subtree to find dt-bindings from under include/dt-bindings. That's been working well, but new DT architectures haven't been adding them by default. Recently there's been a desire to share some of the DT material between arm and arm64, which originally caused developers to create symlinks or relative includes between the subtrees. This isn't ideal -- it breaks if the DT files aren't stored in the exact same hierarchy as the kernel tree, and generally it's just icky. As a somewhat cleaner solution we decided to add a $ARCH/ prefix link once, and allow DTS files to reference dtsi (and dts) files in other architectures that way. Original approach was to create these links under each architecture, but it lead to the problem of recursive symlinks. As a remedy, move the include link directories out of the architecture trees into a common location. At the same time, they can now share one directory and one dt-bindings/ link as well.

* | | kbuild: skip install/check of headers right under uapi directoriesMasahiro Yamada2017-05-181-16/+27
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since commit 61562f981e92 ("uapi: export all arch specifics directories"), "make INSTALL_HDR_PATH=$root/usr headers_install" deletes standard glibc headers and others in $(root)/usr/include. The cause of the issue is that headers_install now starts descending from arch/$(hdr-arch)/include/uapi with $(root)/usr/include for its destination when installing asm headers. So, headers already there are assumed to be unwanted. When headers_install starts descending from include/uapi with $(root)/usr/include for its destination, it works around the problem by creating an dummy destination $(root)/usr/include/uapi, but this is tricky. To fix the problem in a clean way is to skip headers install/check in include/uapi and arch/$(hdr-arch)/include/uapi because we know there are only sub-directories in uapi directories. A good side effect is the empty destination $(root)/usr/include/uapi will go away. I am also removing the trailing slash in the headers_check target to skip checking in arch/$(hdr-arch)/include/uapi.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes the need of subdir-y. Now all files/directories under arch/<arch>/include/uapi/ are exported. The only change for userland is the layout of the command 'make headers_install_all': directories asm-<arch> are replaced by arch-<arch>/. Those new directories contains all files/directories of the specified arch. Note that only cris and tile have more directories than only asm: - arch-v[10|32] for cris; - arch for tile.

However, -Wno-unknown-warning-option makes clang happy with any unknown warning options even if -Werror is specified. Once -Wno-unknown-warning-option is added, any succeeding call of cc-disable-warning is evaluated positive, then unknown warning options are accepted. This should be dropped.

[1] Commit 3234282f33b2 ("x86, asm: Fix CFI macro invocations to deal with shortcomings in gas") added parentheses for defined expressions to support old gas for x86. [2] Commit a22dcdb0032c ("x86, asm: Fix ancient-GAS workaround") split the pattern into two to avoid parentheses for non-numeric expressions. [3] Commit 95a2f6f72d37 ("Partially revert patch that encloses asm-offset.h numbers in brackets") removed parentheses from numeric expressions as well because parentheses in MN10300 assembly have a special meaning (pointer access).

Add the --typedefsfile option as a way to extend the known types and deal with this issue. This was developed for OP-TEE [1]. We run a Travis job on all pull requests [2], and checkpatch is part of that. The typical false warning we get on a regular basis is with some pointers to functions returning TEE_Result [3], which is a typedef from the GlobalPlatform APIs. We consider it is acceptable to use GP types in the OP-TEE core implementation, that's why this patch would be helpful for us.

Disable the new dtc warnings by default as there are 1000s. As before, warnings are enabled with W=1 or W=2. The strict node and property name checks are a bit subjective, so they are only enabled for W=2. Signed-off-by: Rob Herring <robh@kernel.org>
