The prototypes in syscalls.h all make sense for

When legacy signal handling is disabled, the
arch/microblaze/kernel/signal.c implementation can
be much simpler, as most of it is handled generically
from kernel/signal.c.This is also a prerequisite for using the generic
asm/unistd.h, which does not provide __NR_sigreturn,
because this macro is referenced by the current signal.c
implementation.Signed-off-by: Arnd Bergmann

All the simple microblaze header files were adapted to use their
asm-generic implementations. These files are more simple and were quite
straightforward to change.fb.h, vga.h and parport.h previously did not exist, using
the generic version makes it possible to build more drivers
successfully in allyesonfig.Signed-off-by: Remis Lima Baima

Re-introduce this, but tied in properly with the 'iommu=pt' support this

If an o32 process generates a core dump on a 64 bit kernel, the core file
will not be correctly recognized. This is because ELF_CORE_COPY_REGS and
ELF_CORE_COPY_TASK_REGS are not correctly defined for o32 and will use
the default register set which would be CONFIG_64BIT in asm/elf.h.So we'll switch to use the right register defines in this situation by
checking for WANT_COMPAT_REG_H and use the right defines of
ELF_CORE_COPY_REGS and ELF_CORE_COPY_TASK_REGS.[Ralf: made ELF_CORE_COPY_TASK_REGS() bullet-proof against funny arguments.]

Some CPUs implement mipsr2, but because they are a super-set of mips64r2 do
not define CONFIG_CPU_MIPS64_R2. Cavium OCTEON falls into this category.
We would still like to use the optimized implementation, so since we have
already checked for CONFIG_CPU_MIPSR2, checking for CONFIG_64BIT instead of
CONFIG_CPU_MIPS64_R2 is sufficient.Signed-off-by: David Daney
