parisc: Fix /proc/cpuinfo output for lscpu 2023-09-19T10:20:22+00:00 Helge Deller deller@gmx.de 2023-08-18T20:48:04+00:00 9f73fd6972bcafe602eea6b753dde6919b2638a9 commit 9f5ba4b3e1b3c123eeca5d2d09161e8720048b5c upstream. The lscpu command is broken since commit cab56b51ec0e ("parisc: Fix device names in /proc/iomem") added the PA pathname to all PA devices, includig the CPUs. lscpu parses /proc/cpuinfo and now believes it found different CPU types since every CPU is listed with an unique identifier (PA pathname). Fix this problem by simply dropping the PA pathname when listing the CPUs in /proc/cpuinfo. There is no need to show the pathname in this procfs file.

commit 9f5ba4b3e1b3c123eeca5d2d09161e8720048b5c upstream.

The lscpu command is broken since commit cab56b51ec0e ("parisc: Fix
device names in /proc/iomem") added the PA pathname to all PA
devices, includig the CPUs.

lscpu parses /proc/cpuinfo and now believes it found different CPU
types since every CPU is listed with an unique identifier (PA
pathname).

Fix this problem by simply dropping the PA pathname when listing the
CPUs in /proc/cpuinfo. There is no need to show the pathname in this
procfs file.
