[BISECTED] 164UX Regression, 2.6.22->2.6.23

Hello,
Alpha/Linux user Ian Las reported that since 2.6.22, the Kernel fails to load
on his 164UX using MILO. (MILO is the only way to load Linux, as it only has
ARCSBIOS.)

It fails with

...Image loaded into memory, entry @ 0xfffffc0000310000
Setting up Milo reboot parameter block at 0xfffffc0000000140
Boot line is bootdevice=sdb2 bootfile=vmlinux.gz root=/dev/sdb6
Bootstrap complete, kernel @ 0xfffffc0000310000, sp @ 0xfffffc0000304000
...turning on virtual addressing and jumping to the Linux Kernel
--------------------------------------------------------------------------------
Kernel panic - not syncing: Attempted to kill init!

Ian successfully bisected the failing commit, inline below. We tried reverting
the commit, but it causes linker failures due to overlapping sections.

How can we further debug and fix this?

Thanks!
Matt

    alpha: Put allocated ELF notes in read-only data segment
    
    This changes the alpha linker script to use the asm-generic NOTES macro so
    that ELF note sections with SHF_ALLOC set are linked into the kernel image
    along with other read-only data.  The PT_NOTE also points to their location.
    
    This paves the way for putting useful build-time information into ELF notes
    that can be found easily later in a kernel memory dump.
