move asm/unaligned.h to linux/unaligned.h2024-10-02T21:23:23ZAl Viro2024-10-01T19:35:57Zurn:sha1:5f60d5f6bbc12e782fac78110b0ee62698f3b576
asm/unaligned.h is always an include of asm-generic/unaligned.h;
might as well move that thing to linux/unaligned.h and include
that - there's nothing arch-specific in that header.
auto-generated by the following:
for i in `git grep -l -w asm/unaligned.h`; do
sed -i -e "s/asm\/unaligned.h/linux\/unaligned.h/" $i
done

sed -i -e "s/asm-generic\/unaligned.h/linux\/unaligned.h/" $i

git mv include/asm-generic/unaligned.h include/linux/unaligned.h

parisc: get rid of private asm/unaligned.h2024-10-02T03:20:41ZAl Viro2023-12-06T02:53:22Zurn:sha1:134d988208602ccae792e91475c05911c962798e
Declarations local to arch/*/kernel/*.c are better off *not* in a public
header - arch/parisc/kernel/unaligned.h is just fine for those
bits.
With that done parisc asm/unaligned.h is reduced to include
of asm-generic/unaligned.h and can be removed - unaligned.h is in
mandatory-y in include/asm-generic/Kbuild.

This function pointer is only used by one function, so no need
to keep such an indirection.

The kernel kgdb break instructions should only be handled when running
in kernel context.

parisc: Add lightweight spinlock checks2023-05-24T12:23:07ZHelge Deller2023-05-22T13:11:16Zurn:sha1:15e64ef6520ea8702998db05b87fa5c3d3d40710
Add a lightweight spinlock check which uses only two instructions
per spinlock call. It detects if a spinlock has been trashed by
some memory corruption and then halts the kernel. It will not detect
uninitialized spinlocks, for which CONFIG_DEBUG_SPINLOCK needs to
be enabled.
This lightweight spinlock check shouldn't influence runtime, so it's
safe to enable it by default.
The __ARCH_SPIN_LOCK_UNLOCKED_VAL constant has been choosen small enough
to be able to be loaded by one LDI assembler statement.

parisc: Convert PDC console to an early console2022-10-11T10:01:24ZHelge Deller2022-09-30T22:32:07Zurn:sha1:027c3d345e2a1ea61d6e4506a250eb392e6e7b18
Rewrite the PDC console to become an early console.
Beside the fact that now boot information is visible until another
(text- or graphics) console takes over, this benefits as well machines
with a yet-unsupported STI console and kgdb.
