* MIPS: Only include the platform file neededThomas Bogendoerfer2020-05-131-1/+0
| | | | | | | Instead of including all Platform files, we simply include the needed one and avoid clashes with makefile variables. Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de>

CC arch/mips/vdso/gettimeofday.o In file included from ../arch/mips/vdso/vdso.h:26, from ../arch/mips/vdso/gettimeofday.c:11: ../arch/mips/include/asm/page.h:12:10: fatal error: spaces.h: No such file or directory #include <spaces.h> ^~~~~~~~~~ The cause of the error is a missing space after the compiler flag -I . Kbuild used to have a global restriction "no space after -I", but commit 48f6e3cf5bc6 ("kbuild: do not drop -I without parameter") got rid of it. Having a space after -I is no longer a big deal as far as Kbuild is concerned. It is still a big deal for MIPS because arch/mips/vdso/Makefile filters the header search paths, like this: ccflags-vdso := \ $(filter -I%,$(KBUILD_CFLAGS)) \ ..., which relies on the assumption that there is no space after -I .

* treewide: prefix header search paths with $(srctree)/Masahiro Yamada2019-05-181-1/+1
| | | | | | | | | | | | | | | | | 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").

| | | | | | | | | | | | | | We regularly have new NAND controller drivers that are making use of fields/hooks that we want to get rid of but can't because of all the legacy drivers that we might break if we do. So, instead of removing those fields/hooks, let's move them to a sub-struct which is clearly documented as deprecated. We start with the ->IO_ADDR_{R,W] fields.

* mtd: rawnand: plat_nand: Pass a nand_chip object to all platform_nand_ctrl hooksBoris Brezillon2018-10-031-2/+1
| | | | | | | | | | | | | | | | | | | | | Let's make the raw NAND API consistent by patching all helpers and hooks to take a nand_chip object instead of an mtd_info one or remove the mtd_info object when both are passed. In order to do that, we first need to update the platform_nand_ctrl hooks to take a nand_chip object instead of an mtd_info. We add temporary plat_nand_xxx() wrappers to the do the mtd -> chip conversion, but those will be dropped when patching nand_chip hooks to take a nand_chip object.

* MIPS: Delete __cpuinit/__CPUINIT usage from MIPS codePaul Gortmaker2013-07-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 3747069b25e419f6b51395f48127e9812abc3596 upstream. The __cpuinit type of throwaway sections might have made sense some time ago when RAM was more constrained, but now the savings do not offset the cost and complications. For example, the fix in commit 5e427ec2d0 ("x86: Fix bit corruption at CPU resume time") is a good example of the nasty type of bugs that can be created with improper use of the various __init prefixes. After a discussion on LKML[1] it was decided that cpuinit should go the way of devinit and be phased out. Once all the users are gone, we can then finally remove the macros themselves from linux/init.h. Note that some harmless section mismatch warnings may result, since notify_cpu_starting() and cpu_up() are arch independent (kernel/cpu.c) and are flagged as __cpuinit -- so if we remove the __cpuinit from the arch specific callers, we will also get section mismatch warnings. As an intermediate step, we intend to turn the linux/init.h cpuinit related content into no-ops as early as possible, since that will get rid of these warnings. In any case, they are temporary and harmless. Here, we remove all the MIPS __cpuinit from C code and __CPUINIT from asm files. MIPS is interesting in this respect, because there are also uasm users hiding behind their own renamed versions of the __cpuinit macros.
