For improved const-correctness.
This piece is necessary to make the `rlim_stack` parameter to mmap_base()
const.

parisc: Replace __ASSEMBLY__ with __ASSEMBLER__ in non-uapi headers2025-05-04T18:46:27+00:00Thomas Huththuth@redhat.com2025-03-14T07:09:56+00:00urn:sha1:cccaea1d66e94bd42170c9372964a2ce62418fb1
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 mostly a completely mechanical patch (done with a simple
"sed -i" statement), except for some manual tweaks in the files
arch/parisc/include/asm/smp.h, arch/parisc/include/asm/signal.h,
arch/parisc/include/asm/thread_info.h and arch/parisc/include/asm/vdso.h
that had the macro spelled in a wrong way.

parisc: fix mmap_base calculation when stack grows upwards2023-11-15T23:30:09+00:00Helge Dellerdeller@gmx.de2023-11-13T10:12:57+00:00urn:sha1:5f74f820f6fc844b95f9e5e406e0a07d97510420
Matoro reported various userspace crashes on the parisc platform with kernel
6.6 and bisected it to commit 3033cd430768 ("parisc: Use generic mmap top-down
layout and brk randomization").
That commit switched parisc to use the common infrastructure to calculate
mmap_base, but missed that the mmap_base() function takes care for
architectures where the stack grows downwards only.
Fix the mmap_base() calculation to include the stack-grows-upwards case
and thus fix the userspace crashes on parisc.
