Thank you!
Hi Linus, 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. Please pull. Thanks!
