5f60d5f6 - move asm/unaligned.h to linux/unaligned.h

move asm/unaligned.h to linux/unaligned.hasm/unaligned.h is always an include of asm-generic/unaligned.h;might as well move that thing to linux/unaligned.h and includethat - there's nothing arch-specific in that header.auto-generated by the following:for i in `git grep -l -w asm/unaligned.h`; do sed -i -e "s/asm\/unaligned.h/linux\/unaligned.h/" $idonefor i in `git grep -l -w asm-generic/unaligned.h`; do sed -i -e "s/asm-generic\/unaligned.h/linux\/unaligned.h/" $idonegit mv include/asm-generic/unaligned.h include/linux/unaligned.hgit mv tools/include/asm-generic/unaligned.h tools/include/linux/unaligned.hsed -i -e "/unaligned.h/d" include/asm-generic/Kbuildsed -i -e "s/__ASM_GENERIC/__LINUX/" include/linux/unaligned.h tools/include/linux/unaligned.h List of files: /linux-6.15/arch/arc/kernel/unwind.c

ac3b4328 - module: replace module_layout with module_memory

Tue, 07 Feb 2023 00:28:02 +0000

module: replace module_layout with module_memorymodule_layout manages different types of memory (text, data, rodata, etc.)in one allocation, which is problematic for some reasons:1. It is hard to enable CONFIG_STRICT_MODULE_RWX.2. It is hard to use huge pages in modules (and not break strict rwx).3. Many archs uses module_layout for arch-specific data, but it is not obvious how these data are used (are they RO, RX, or RW?)Improve the scenario by replacing 2 (or 3) module_layout per module withup to 7 module_memory per module: MOD_TEXT, MOD_DATA, MOD_RODATA, MOD_RO_AFTER_INIT, MOD_INIT_TEXT, MOD_INIT_DATA, MOD_INIT_RODATA,and allocating them separately. This adds slightly more entries tomod_tree (from up to 3 entries per module, to up to 7 entries permodule). However, this at most adds a small constant overhead to__module_address(), which is expected to be fast.Various archs use module_layout for different data. These data are putinto different module_memory based on their location in module_layout.IOW, data that used to go with text is allocated with MOD_MEM_TYPE_TEXT;data that used to go with data is allocated with MOD_MEM_TYPE_DATA, etc.module_memory simplifies quite some of the module code. For example,ARCH_WANTS_MODULES_DATA_IN_VMALLOC is a lot cleaner, as it just uses adifferent allocator for the data. kernel/module/strict_rwx.c is alsomuch cleaner with module_memory.Signed-off-by: Song Liu Cc: Luis Chamberlain Cc: Thomas Gleixner Cc: Peter Zijlstra Cc: Guenter Roeck Cc: Christophe Leroy Reviewed-by: Thomas Gleixner Reviewed-by: Christophe Leroy Reviewed-by: Luis Chamberlain Signed-off-by: Luis Chamberlain List of files: /linux-6.15/arch/arc/kernel/unwind.c
