Note that .data.page_aligned and .data.cacheline_aligned are now after _data; it was probably a bug that they were before it. Also, some explicit ALIGN(8)'s between various initcall sections were removed; this should be harmless as the implicit alignment of initcall_t was already 8.

The re-addition of the TIF_NOTIFY_RESUME flag, commit d0420c83f39f "KEYS: Extend TIF_NOTIFY_RESUME to (almost) all architectures [try #6]" further caused problems, namely incorrect operands to assembler code as evidenced by: AS arch/alpha/kernel/entry.o arch/alpha/kernel/entry.S: Assembler messages: arch/alpha/kernel/entry.S:326: Warning: operand out of range (0x0000000000000406 is not between 0x0000000000000000 and 0x00000000000000ff) Both regressions fixed by (1) rearranging TIF_NOTIFY_RESUME flag to be in lower 8 bits of the thread info flags, and (2) making sure that ALPHA_UAC_SHIFT matches the rearrangement of the thread info flags.
