microblaze: Replace ASSEMBLY with ASSEMBLER in non-uapi headers

2025-09-12T11:12:42+00:00

While the GCC and Clang compilers already define __ASSEMBLER__ automatically when compiling assembly code, __ASSEMBLY__ is a macro that only gets defined by the Makefiles in the kernel. This can be very confusing when switching between userspace and kernelspace coding, or when dealing with uapi headers that rather should use __ASSEMBLER__ instead. So let's standardize on the __ASSEMBLER__ macro that is provided by the compilers now. This is a completely mechanical patch (done with a simple "sed -i" statement).

arch/microblaze/include/asm/entry.h: Include "linux/linkage.h" to avoid compiling issue

2014-09-09T11:10:20+00:00

"entry.h" needs 'asmlinkage', and "asm/linkage.h" does not provide it. So need include "linux/linkage.h" to use generic one instead of.

microblaze: Remove r0_ram pointer and PTO alignment

2011-03-09T07:09:54+00:00

r0_ram pool was used for saving/restoring register content if hw exception happen. This poll was replaced by pt_pool_space with PT_SIZE size. Based on this change SAVE_STATE_ARG_SPACE was removed which caused that PTO offset is zero that's why is also removed. r0_ram space was used as scratchpad by v850. In early Microblaze Linux developing phase was this part of code blindly copied. Signed-off-by: Michal Simek

percpu: remove per_cpu__ prefix.

2009-10-29T13:34:15+00:00

Now that the return from alloc_percpu is compatible with the address of per-cpu vars, it makes sense to hand around the address of per-cpu variables. To make this sane, we remove the per_cpu__ prefix we used created to stop people accidentally using these vars directly. Now we have sparse, we can use that (next patch). tj: * Updated to convert stuff which were missed by or added after the original patch. * Kill per_cpu_var() macro.
