gcov: enable GCOV_PROFILE_ALL from ARCH Kconfigs Following the suggestions from Andrew Morton and Stephen Rothwell, Dont expand the ARCH list in kernel/gcov/Kconfig. Instead, define a ARCH_HAS_GCOV_PROFILE_ALL bool which architectures can enable. set ARCH_HAS_GCOV_PROFILE_ALL on Architectures where it was previously allowed + ARM64 which I tested.

ipc: use Kconfig options for __ARCH_WANT_[COMPAT_]IPC_PARSE_VERSION Rather than #define the options manually in the architecture code, add Kconfig options for them and select them there instead. This also allows us to select the compat IPC version parsing automatically for platforms using the old compat IPC interface.

microblaze: switch to GENERIC_PCI_IOMAP microblaze copied pci_iomap from generic code, probably to avoid pulling the rest of iomap.c in. Since that's in a separate file now, we can reuse the common implementation. The only difference is handling of nocache flag, that turns out to be done correctly by the generic code since arch/microblaze/include/asm/io.h defines ioremap_nocache same as ioremap.

Make most arch asm/module.h files use asm-generic/module.h Use the mapping of Elf_[SPE]hdr, Elf_Addr, Elf_Sym, Elf_Dyn, Elf_Rel/Rela, ELF_R_TYPE() and ELF_R_SYM() to either the 32-bit version or the 64-bit version into asm-generic/module.h for all arches bar MIPS. Also, use the generic definition mod_arch_specific where possible. To this end, I've defined three new config bools: (*) HAVE_MOD_ARCH_SPECIFIC Arches define this if they don't want to use the empty generic mod_arch_specific struct. (*) MODULES_USE_ELF_RELA Arches define this if their modules can contain RELA records. This causes the Elf_Rela mapping to be emitted and allows apply_relocate_add() to be defined by the arch rather than have the core emit an error message. (*) MODULES_USE_ELF_REL Arches define this if their modules can contain REL records. This causes the Elf_Rel mapping to be emitted and allows apply_relocate() to be defined by the arch rather than have the core emit an error message. Note that it is possible to allow both REL and RELA records: m68k and mips are two arches that do this. With this, some arch asm/module.h files can be deleted entirely and replaced with a generic-y marker in the arch Kbuild file. Additionally, I have removed the bits from m32r and score that handle the unsupported type of relocation record as that's now handled centrally.

microblaze: Stack trace support This is working implemetation but the problem is that Microblaze misses frame pointer that's why is there big loop which trace and show all addresses which are in text. It shows addresses which are in registers, etc. This is problem and this is the reason why all Microblaze traces are wrong. There is an option to do hacks and trace the kernel code but this is too complicated. Signed-off-by: Michal Simek <monstr@monstr.eu>

microblaze: Lockdep support Microblaze needs to do lock_init very soon because MMU init calls lock functions. Here is the explanation from Peter Zijlstra why we have to enable __ARCH_WANTS_INTERRUPTS_ON_CTSW. "So we schedule while holding rq->lock (for obvious reasons), but since lockdep tracks held locks per tasks, we need to transfer the held state from the prev to the next task. We do this by explicity calling spin_release(&rq->lock) in context_switch() right before switch_to(), and calling spin_acquire(&rq->lock) in finish_task_switch()->finish_lock_switch(). Now, for some reason lockdep thinks that interrupts got enabled over the context switch (git grep __ARCH_WANTS_INTERRUPTS_ON_CTSW arch/microblaze doesn't seem to turn up anything). Clearly trying to acquire the rq->lock with interrupts enabled is a bad idea and lockdep warns you about this." Signed-off-by: Michal Simek <monstr@monstr.eu>

microblaze: Add consistent code Remove ancient Kconfig option for consistent code. MMU uses cache inhibit pages. noMMU uses UNCACHE SHADOW feature where is used double ram size. For example: Physical ram is 256MB and cache are setup to cover the same size. But if you setup in HW that size is 512MB and cache covers 256MB than you can use adresses from 256-512MB without caches and correspond with 0-256MB with cache. That's why I am using dcache base/high addresses to find out uncache area. Signed-off-by: Michal Simek <monstr@monstr.eu>
