Caused by commit 2bdd5238e756 ("PCI: mt7621: Add MediaTek MT7621 PCIe host controller driver") which states "depends on (RALINK && SOC_MT7621) || (MIPS && COMPILE_TEST)" (I guess mips:allmodconfig wasn't tested). parisc:allmodconfig: Lots of build failures in arch/parisc/include/asm/jump_label.h. Not fixed in -next. The problem seens to be related to the thread_info changes, or at least bisect points to commit 01463374c50e ("Merge tag 'cpu-to-thread_info-v5.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux"). powerpc:allmodconfig fs/ntfs/aops.c: In function 'ntfs_write_mst_block': fs/ntfs/aops.c:1311:1: error: the frame size of 2240 bytes is larger than 2048 bytes Bisect points to commit f22969a6604 ("powerpc/64s: Default to 64K pages for 64 bit book3s"), and reverting that commit does fix the problem. The problem is ntfs_inode *locked_nis[PAGE_SIZE / NTFS_BLOCK_SIZE]; I don't see the problem in next-20211115, but I don't immediately see how it was fixed there. powerpc:ppc6xx_defconfig arch/powerpc/platforms/83xx/mcu_mpc8349emitx.c: In function 'mcu_remove': arch/powerpc/platforms/83xx/mcu_mpc8349emitx.c:189:13: error: unused variable 'ret' Caused by commit 5d354dc35ebb ("powerpc/83xx/mpc8349emitx: Make mcu_gpiochip_remove() return void").
