kernel/linux.git/arch/x86/include/asm/current.h, branch v6.18.22Linux kernel stable tree (mirror)https://git.radix-linux.su/kernel/linux.git/atom?h=v6.18.222025-03-19T10:47:30+00:00x86/headers: Replace __ASSEMBLY__ with __ASSEMBLER__ in non-UAPI headers2025-03-19T10:47:30+00:00Thomas Huththuth@redhat.com2025-03-19T10:30:57+00:00urn:sha1:24a295e4ef1ca8e97d8b7015e1887b6e83e1c8be
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 mechanical patch (done with a simple "sed -i"
statement), with some manual tweaks in <asm/frame.h>, <asm/hw_irq.h>
and <asm/setup.h> that mentioned this macro in comments with some
missing underscores.

Also change the alignment of the percpu hot section:
- PERCPU_SECTION(INTERNODE_CACHE_BYTES)
+ PERCPU_SECTION(L1_CACHE_BYTES)
As vSMP will muck with INTERNODE_CACHE_BYTES that invalidates the
too-large-section assert we do:
ASSERT(__per_cpu_hot_end - __per_cpu_hot_start <= 64, "percpu cache hot section too large")
[ mingo: Added INTERNODE_CACHE_BYTES fix & explanation. ]
