We define sp and ipsw in <asm/asmregs.h> using ".reg", and when using
current binutils (snapshot 2.40.50.20230611) the definitions in
<asm/assembly.h> using "=" conflict with those:
arch/parisc/include/asm/assembly.h: Assembler messages:
arch/parisc/include/asm/assembly.h:93: Error: symbol `sp' is already defined
arch/parisc/include/asm/assembly.h:95: Error: symbol `ipsw' is already defined
Delete the duplicate definitions in <asm/assembly.h>.
Also delete the definition of gp, which isn't used anywhere.

parisc: Add dep_safe() macro to deposit a register in 32- and 64-kernels2022-05-23T11:44:24+00:00Helge Dellerdeller@gmx.de2022-05-17T15:03:01+00:00urn:sha1:cdd00fe6aa52870b54797e1386aac6202d916763

parisc: Fix wrong comment for shr macro2022-05-23T11:44:24+00:00Helge Dellerdeller@gmx.de2022-05-17T15:01:12+00:00urn:sha1:be6aee1392c46cd6f537aea75b1ce7ec427d36f4
The comment that the source and target register can not be the same is
wrong. Instead on PA2.0 usage of extru can clobber upper 32-bits.
This patch fixes the comment.

parisc: Add defines for various space register2022-03-11T18:49:30+00:00Helge Dellerdeller@gmx.de2022-02-17T20:29:22+00:00urn:sha1:46b4016f7d3b1c16c5eefcdf16dd32e84f4dbb60
Provide defines for space registers (SR_KERNEL, SR_USER, ...) which
should be used instead of hardcoding the values.

parisc: Define depi_safe macro2022-01-07T00:29:20+00:00John David Anglindave.anglin@bell.net2021-12-21T20:04:53+00:00urn:sha1:45458aa49abe3b0ac68ce86b3d4ca3a97eaeac53
The depi instruction is similar to the extru instruction on 64-bit machines.
It leaves the most-significant 32 bits of the target register in an undefined
state. On 64-bit machines, the macro uses depdi to perform safe deposits in
the least-significant 32 bits.

The extru instruction leaves the most significant 32 bits of the
target register in an undefined state on PA 2.0 systems.
Provide a macro to safely use extru on 32- and 64-bit machines.

parisc: Wrap assembler related defines inside __ASSEMBLY__2021-11-18T08:02:00+00:00Helge Dellerdeller@gmx.de2021-11-16T12:12:21+00:00urn:sha1:4017b230c960c9d6c6a19e52bf3df01222dc7737
Building allmodconfig shows errors in the gpu/drm/msm snapdragon drivers,
because a COND() define is used there which conflicts with the COND() for
PA-RISC assembly. Although the snapdragon driver isn't relevant for parisc, it
is nevertheless compiled when CONFIG_COMPILE_TEST is defined.
Move the COND() define and other PA-RISC mnemonics inside the #ifdef
__ASSEMBLY__ part to avoid this conflict.
