8a62d445 - scripts: subarch.include: fix SUBARCH on macOS hosts

scripts: subarch.include: fix SUBARCH on macOS hostsWhen building the Linux kernel on an aarch64 macOS based host, if we don'tspecify a value for ARCH when invoking make, we default to arm and thusmulti_v7_defconfig rather than the expected arm64 and arm64's defconfig.This is because subarch.include invokes `uname -m` which on MacOS hostsevaluates to `arm64` but on Linux hosts evaluates to `aarch64`,This allows us to build ARCH=arm64 natively on macOS (as in ARCH neednot be specified on an aarch64-based system).Avoid matching arm64 by excluding it from the arm.* sed expression.Signed-off-by: Nick Desaulniers Suggested-by: Nicolas Schier Signed-off-by: Daniel Gomez Signed-off-by: Masahiro Yamada List of files: /linux-6.15/scripts/subarch.include

5f6e0fe0 - parisc: Fix compile failure when building 64-bit kernel natively

parisc: Fix compile failure when building 64-bit kernel nativelyCommit 23243c1ace9f ("arch: use cross_compiling to check whether it isa cross build or not") broke 64-bit parisc builds on 32-bit pariscsystems.Helge mentioned: - 64-bit parisc userspace is not supported yet [1] - hppa gcc does not support "-m64" flag [2]That means, parisc developers working on a 32-bit parisc machine needto use hppa64-linux-gnu-gcc (cross compiler) for building the 64-bitparisc kernel.After the offending commit, gcc is used in such a case becauseboth $(SRCARCH) and $(SUBARCH) are 'parisc', hence cross_compiling isunset.A correct way is to introduce ARCH=parisc64 because building the 64-bitparisc kernel on a 32-bit parisc system is not exactly a native build,but rather a semi-cross build.[1]: https://lore.kernel.org/linux-parisc/5dfd81eb-c8ca-b7f5-e80e-8632767c022d@gmx.de/#t[2]: https://lore.kernel.org/linux-parisc/89515325-fc21-31da-d238-6f7a9abbf9a0@gmx.de/Fixes: 23243c1ace9f ("arch: use cross_compiling to check whether it is a cross build or not")Signed-off-by: Masahiro Yamada Reported-by: Meelis Roos Tested-by: Meelis Roos Cc: # v5.13+Signed-off-by: Helge Deller List of files: /linux-6.15/scripts/subarch.include

b2d35fa5 - selftests: add headers_install to lib.mk

Tue, 04 Sep 2018 10:47:21 +0000

selftests: add headers_install to lib.mkIf the kernel headers aren't installed we can't build all the tests.Add a new make target rule 'khdr' in the file lib.mk to generate thekernel headers and that gets include for every test-dir Makefile thatincludes lib.mk If the testdir in turn have its own sub-dirs thetop_srcdir needs to be set to the linux-rootdir to be able to generatethe kernel headers.Signed-off-by: Anders Roxell Reviewed-by: Fathi Boudra Signed-off-by: Shuah Khan (Samsung OSG) List of files: /linux-6.15/scripts/subarch.include
