* unicore32: simplify linker script generation for decompressorMasahiro Yamada2019-03-142-4/+1
| | | | | | | | | | | | | | When I was searching for unneeded $(KCONFIG_CONFIG) usages, I noticed this strange build dependency. It can use $(call if_changed,...) in case ZTEXTADDR and ZBSSADDR are changed, but even a simpler way is to use the pattern rule in scripts/Makefile.build. This is what arch/arm/boot/compressed/Makefile does. I did only build test. I confirmed equivalent vmlinux.lds was generated. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* h8300: use cc-cross-prefix instead of hardcoding h8300-unknown-linux-Masahiro Yamada2019-03-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It believe it is a bad idea to hardcode a specific compiler prefix that may or may not be installed on a user's system. It is annoying when testing features that should not require compilers at all. For example, mrproper, headers_install, etc. should work without any compiler. They look like follows on my machine. $ make ARCH=h8300 mrproper ./scripts/gcc-version.sh: line 26: h8300-unknown-linux-gcc: command not found ./scripts/gcc-version.sh: line 27: h8300-unknown-linux-gcc: command not found make: h8300-unknown-linux-gcc: Command not found make: h8300-unknown-linux-gcc: Command not found [ a bunch of the same error messages continue ] $ make ARCH=h8300 headers_install ./scripts/gcc-version.sh: line 26: h8300-unknown-linux-gcc: command not found ./scripts/gcc-version.sh: line 27: h8300-unknown-linux-gcc: command not found make: h8300-unknown-linux-gcc: Command not found HOSTCC scripts/basic/fixdep make: h8300-unknown-linux-gcc: Command not found WRAP arch/h8300/include/generated/uapi/asm/kvm_para.h [ snip ] The solution is to delete this line, or to use cc-cross-prefix like some architectures do. I chose the latter as a moderate fixup. I added an alternative 'h8300-linux-' because it is available at: https://mirrors.edge.kernel.org/pub/tools/crosstool/files/bin/x86_64/8.1.0/ Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* kbuild: move archive command to scripts/Makefile.libMasahiro Yamada2019-03-143-8/+7
| | | | | | | | | scripts/Makefile.build and arch/s390/boot/Makefile use the same command (thin archiving with symbol table creation). Avoid the code duplication, and move it to scripts/Makefile.lib. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* modpost: always show verbose warning for section mismatchMasahiro Yamada2019-03-142-23/+5
| | | | | | | | | | | | | Unless CONFIG_DEBUG_SECTION_MISMATCH is enabled, modpost only shows the number of section mismatches. If you want to know the symbols causing the issue, you need to rebuild with CONFIG_DEBUG_SECTION_MISMATCH. It is tedious. I think it is fine to show annoying warning when a new section mismatch comes in. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ia64: prefix header search path with $(srctree)/Masahiro Yamada2019-03-144-6/+2
| | | | | | | | | | | | | | | | | | | | Currently, the Kbuild core manipulates header search paths in a crazy way [1]. To fix this mess, I want all Makefiles to add explicit $(srctree)/ to the search paths in the srctree. Some Makefiles are already written in that way, but not all. The goal of this work is to make the notation consistent, and finally get rid of the gross hacks. Having whitespaces after -I does not matter since commit 48f6e3cf5bc6 ("kbuild: do not drop -I without parameter"). I removed some header search paths because I was able to build ia64 without them.

* deb-pkg: generate correct build dependenciesRiku Voipio2019-03-141-1/+3
| | | | | | | | | | | | | | | | | | | bison/flex is now needed always for building for kconfig. Some build dependencies depend on kernel configuration, enable them as needed: - libelf-dev when UNWINDER_ORC is set - libssl-dev for SYSTEM_TRUSTED_KEYRING Since the libssl-dev is needed for extract_cert binary, denote with :native to install the libssl-dev for the build machines architecture, rather than for the architecture of the kernel being built.

This behavior differs with legacy APIs a little. Legacy APIs: The PWMCNT register will be updated in rcar_pwm_config() even if the PWM state is disabled. Atomic API: The PWMCNT register will be updated in rcar_pwm_apply() only if the PWM state is enabled. Otherwize, if a PWM runs with 30% duty cycles and the pwm_apply_state() is called with state->enabled = 0, ->duty_cycle = 60 and ->period = 100, this is possible to output a 60% duty cycle.
