scripts: fix the gfp flags header path in gfp-translate

2023-06-28T09:12:22+00:00

commit 2049a7d0cbc6ac8e370e836ed68597be04a7dc49 upstream. Since gfp flags have been shifted to gfp_types.h so update the path in the gfp-translate script.

kbuild: Update assembler calls to use proper flags and language target

2023-06-21T14:01:03+00:00

commit d5c8d6e0fa61401a729e9eb6a9c7077b2d3aebb0 upstream. as-instr uses KBUILD_AFLAGS, but as-option uses KBUILD_CFLAGS. This can cause as-option to fail unexpectedly when CONFIG_WERROR is set, because clang will emit -Werror,-Wunused-command-line-argument for various -m and -f flags in KBUILD_CFLAGS for assembler sources. Callers of as-option and as-instr should be adding flags to KBUILD_AFLAGS / aflags-y, not KBUILD_CFLAGS / cflags-y. Use KBUILD_AFLAGS in all macros to clear up the initial problem. Unfortunately, -Wunused-command-line-argument can still be triggered with clang by the presence of warning flags or macro definitions because '-x assembler' is used, instead of '-x assembler-with-cpp', which will consume these flags. Switch to '-x assembler-with-cpp' in places where '-x assembler' is used, as the compiler is always used as the driver for out of line assembler sources in the kernel. Finally, add -Werror to these macros so that they behave consistently whether or not CONFIG_WERROR is set.

scripts/gdb: fix lx-timerlist for Python3

2023-05-11T14:03:40+00:00

commit 7362042f3556528e9e9b1eb5ce8d7a3a6331476b upstream. Below incompatibilities between Python2 and Python3 made lx-timerlist fail to run under Python3. o xrange() is replaced by range() in Python3 o bytes and str are different types in Python3 o the return value of Inferior.read_memory() is memoryview object in Python3 akpm: cc stable so that older kernels are properly debuggable under newer Python.

modpost: Fix processing of CRCs on 32-bit build machines

2023-04-06T10:10:53+00:00

commit fb27e70f6e408dee5d22b083e7a38a59e6118253 upstream. modpost now reads CRCs from .*.cmd files, parsing them using strtol(). This is inconsistent with its parsing of Module.symvers and with their definition as *unsigned* 32-bit values. strtol() clamps values to [LONG_MIN, LONG_MAX], and when building on a 32-bit system this changes all CRCs >= 0x80000000 to be 0x7fffffff. Change extract_crcs_for_object() to use strtoul() instead.
