* lib/vsprintf: Remove support for %pF and %pf in favour of %pS and %psSakari Ailus2019-10-113-19/+2
| | | | | | | | | | | | | %pS and %ps are now the preferred conversion specifiers to print function names. The functionality is equivalent; remove the old, deprecated %pF and %pf support.

* device property: Add fwnode_get_name for returning the name of a nodeSakari Ailus2019-10-116-0/+58
| | | | | | | | | | | The fwnode framework did not have means to obtain the name of a node. Add that now, in form of the fwnode_get_name() function and a corresponding get_name fwnode op.

* elf: don't use MAP_FIXED_NOREPLACE for elf executable mappingsLinus Torvalds2019-10-061-10/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In commit 4ed28639519c ("fs, elf: drop MAP_FIXED usage from elf_map") we changed elf to use MAP_FIXED_NOREPLACE instead of MAP_FIXED for the executable mappings. Then, people reported that it broke some binaries that had overlapping segments from the same file, and commit ad55eac74f20 ("elf: enforce MAP_FIXED on overlaying elf segments") re-instated MAP_FIXED for some overlaying elf segment cases. But only some - despite the summary line of that commit, it only did it when it also does a temporary brk vma for one obvious overlapping case. Now Russell King reports another overlapping case with old 32-bit x86 binaries, which doesn't trigger that limited case. End result: we had better just drop MAP_FIXED_NOREPLACE entirely, and go back to MAP_FIXED. Yes, it's a sign of old binaries generated with old tool-chains, but we do pride ourselves on not breaking existing setups. This still leaves MAP_FIXED_NOREPLACE in place for the load_elf_interp() and the old load_elf_library() use-cases, because nobody has reported breakage for those. Yet. Note that in all the cases seen so far, the overlapping elf sections seem to be just re-mapping of the same executable with different section attributes. We could possibly introduce a new MAP_FIXED_NOFILECHANGE flag or similar, which acts like NOREPLACE, but allows just remapping the same executable file using different protection flags. It's not clear that would make a huge difference to anything, but if people really hate that "elf remaps over previous maps" behavior, maybe at least a more limited form of remapping would alleviate some concerns. Alternatively, we should take a look at our elf_map() logic to see if we end up not mapping things properly the first time. In the meantime, this is the minimal "don't do that then" patch while people hopefully think about it more.

This is not strictly a fix, but we still also have the older CONFIG_MFD_TI_LMU options available so this cuts down the confusion for trying to guess which display and which backlight is needed - Recent ti-sysc interconnect target module changes need the gpio module disabled on some boards, but this now needs to happen at the module level, not at the gpio driver level - Recent changes to probe system timers with ti-sysc caused warnings about mismatch in syconfig registers, so let's configure the option for RESET_STATUS as available in the TRMs - Recent changes to probe LCDC with ti-sysc caused warnings about mismatch in sysconfig registers, so let's configure the missing idlemodes for both platform data and dts as documented in TRMs - Since we moved mach-omap2 to probe with device tree, we've been getting voltage controller warnings.

This is because lcdc has SYSC_HAS_MIDLEMODE configured in the platform data without configuring the modes. Let's fix the issue by adding the missing midlemode to lcdc_sysc, and configuring the "ti,sysc-midle" property based on the TRM values.

| | * | ARM: OMAP2+: Fix missing reset done flag for am3 and am43Tony Lindgren2019-09-251-1/+2

This is documented for example in am437x TRM for DMTIMER_TIOCP_CFG register. The am335x TRM just says that SOFTRESET bit value 1 means reset is ongoing, but it behaves the same way clearing after reset is done. With the ti-sysc driver handling this automatically based on no sysstatus register defined, we see warnings if SYSC_HAS_RESET_STATUS is missing in the legacy platform data: ti-sysc 48042000.target-module: sysc_flags 00000222 != 00000022 ti-sysc 48044000.target-module: sysc_flags 00000222 != 00000022 ti-sysc 48046000.target-module: sysc_flags 00000222 != 00000022 ... Let's fix these warnings by adding SYSC_HAS_RESET_STATUS. Let's also remove the useless parentheses while at it. If it turns out we do have ti,sysc-omap4 compatible devices without a working SOFTRESET bit we can set up additional quirk handling for it. Signed-off-by: Tony Lindgren <tony@atomide.com>

This assumes that the polarity of the CS has to be inverted if spi-cs-high is missing, even and especially if non-legacy GPIO_ACTIVE_HIGH is specified. The DTS for the GTA04 was orginally introduced under the assumption that there is no need for spi-cs-high if the gpio is defined with proper polarity GPIO_ACTIVE_HIGH. This was not a problem until gpiolib changed the interpretation of GPIO_ACTIVE_HIGH and missing spi-cs-high. The effect is that the missing spi-cs-high is now interpreted as CS being low (despite GPIO_ACTIVE_HIGH) which turns off the SPI interface when the panel is to be programmed by the panel driver. Therefore, we have to add the redundant and legacy spi-cs-high property to properly activate CS. Cc: stable@vger.kernel.org Signed-off-by: H.

The archive containing the header files has nondeterminism caused by header files metadata. This patch normalizes the metadata and utilizes KBUILD_BUILD_TIMESTAMP if provided and otherwise falls back to the default behaviour. In commit f7b101d33046 ("kheaders: Move from proc to sysfs") it was modified to use sysfs and the script for generation of the archive was renamed to what is being patched.

[Steps to Reproduce] $ echo bar > localversion $ mkdir build $ cd build/ $ echo foo > localversion $ make -s -f ../Makefile defconfig include/config/kernel.release $ cat include/config/kernel.release 5.4.0-rc1foofoobar This comes down to the behavior change of local variables. The 'man sh' on my Ubuntu machine, where sh is an alias to dash, explains as follows: When a variable is made local, it inherits the initial value and exported and readonly flags from the variable with the same name in the surrounding scope, if there is one. Otherwise, the variable is initially unset. [Test Code] foo () { local res echo "res: $res" } res=1 foo [Result] $ sh test.sh res: 1 $ bash test.sh res: So, scripts/setlocalversion correctly works only for bash in spite of its hashbang being #!/bin/sh. Nobody had noticed it before because CONFIG_SHELL was previously set to bash almost all the time. Now that CONFIG_SHELL is set to sh, we must write portable and correct code. I gave the Fixes tag to the commit that uncovered the issue. Clear the variable 'res' in collect_files() to make it work for sh (and it also works on distributions where sh is an alias to bash).

The do_nm function is run from within the find function, which changes directories. Because of this, appending objtree, $File::Find::dir, and $source, will return a path which is not valid from the current directory. This used to work when objtree was set to an absolute path when using "make namespacecheck". It appears to have not worked when calling ./scripts/namespace.pl directly. This behavior was changed in 7e1c04779efd ("kbuild: Use relative path for $(objtree)", 2014-05-14) Rather than fixing the Makefile to set objtree to an absolute path, just fix namespace.pl to work when srctree and objtree are relative. Also fix the script to use an absolute path for these by default. Use the File::Spec module for this purpose. It's been part of perl 5 since 5.005. The curdir() function is used to get the current directory when the objtree and srctree aren't set in the environment. rel2abs() is used to convert possibly relative objtree and srctree environment variables to absolute paths. Finally, the catfile() function is used instead of string appending paths together, since this is more robust when joining paths together.

All the warnings above are from the second modpost. The offending symbols are defined not in vmlinux, but in the C library. The first modpost is run against the relocatable vmlinux.o, and those warnings are nicely suppressed because the SH_UNDEF entries from the symbol table clear the ->is_static flag. The second modpost is run against the executable vmlinux (+ modules), where those symbols have been resolved, but the definitions do not exist. This commit fixes it in a straightforward way; suppress the static EXPORT_SYMBOL warnings from "vmlinux". Without this commit, we see valid warnings twice anyway. For example, ARCH=arm64 defconfig shows the following warning twice: WARNING: "HYPERVISOR_platform_op" [vmlinux] is a static EXPORT_SYMBOL_GPL So, it is reasonable to suppress the second one.

According to Documentation/process/changes.rst, the current minimal supported version of binutils is 2.21 so you can assume the 'D' option is always supported. Not only GNU ar but also llvm-ar supports it. With the 'D' option hard-coded, there is no more user of ar-option or KBUILD_ARFLAGS.
