Pull parisc architecture fixes from Helge Deller: "This patchset fixes and enforces correct section alignments for the ex_table, altinstructions, parisc_unwind, jump_table and bug_table which are created by inline assembly. Due to not being correctly aligned at link & load time they can trigger unnecessarily the kernel unaligned exception handler at runtime. While at it, I switched the bug table to use relative addresses which reduces the size of the table by half on 64-bit. We still had the ENOSYM and EREMOTERELEASE errno symbols as left-overs from HP-UX, which now trigger build-issues with glibc. We can simply remove them. Most of the patches are tagged for stable kernel series. Summary: - Drop HP-UX ENOSYM and EREMOTERELEASE return codes to avoid glibc build issues - Fix section alignments for ex_table, altinstructions, parisc unwind table, jump_table and bug_table - Reduce size of bug_table on 64-bit kernel by using relative pointers" * tag 'parisc-for-6.7-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux: parisc: Reduce size of the bug_table on 64-bit kernel by half parisc: Drop the HP-UX ENOSYM and EREMOTERELEASE error codes parisc: Use natural CPU alignment for bug_table parisc: Ensure 32-bit alignment on parisc unwind section parisc: Mark lock_aligned variables 16-byte aligned on SMP parisc: Mark jump_table naturally aligned parisc: Mark altinstructions read-only and 32-bit aligned parisc: Mark ex_table entries 32-bit aligned in uaccess.h parisc: Mark ex_table entries 32-bit aligned in assembly.h
