WITH_INIT_ALL_ZERO and WITH_INIT_ALL_PATTERN are mutually exclusive.
The .error when they were both set broke makeman so demote it to a
warning (and presumably the compiler will fail on an error later on).
We could improve this to make one take precedence but this is sufficient
for now.

There were many, many endianness fixes needed for Radix MMU. The Radix
pagetable is stored in BE (as it is read and written to by the MMU hw),
so we need to convert back and forth every time we interact with it when
running in LE.
With these changes, I can successfully boot with radix enabled on POWER9 hw.

In standards such as LoPAPR, property names in excess of the usual 31
characters exist.
This breaks property traversal.
While in IEEE 1275-1994, nextprop is defined explicitly to work with a
32-byte region of memory, using a larger buffer should be fine. There is
actually no way to pass a buffer length to the nextprop call in the OF
client interface, so SLOF actually just blindly overflows the buffer.
So we have to defensively make the buffer larger, to avoid memory
corruption when reading out long properties on live OF systems.
Note also that on real-mode OF, things are pretty tight because we are
allocating against a static bounce buffer in low memory, so we can't just
use a huge buffer to work around this without it being wasteful of our
limited amount of 32-bit physical memory.
This allows a patched ofwdump to operate properly on SLOF (i.e. pseries)
systems, as well as any other PowerPC systems with overlength properties.

The routine does not serve any practical purpose.
Memory can be allocated in many other ways and most consumers pass the

[ELF] Don't consider SHF_ALLOC ".debug*" sections debug sections
Fixes PR48071
* The Rust compiler produces SHF_ALLOC `.debug_gdb_scripts` (which
normally does not have the flag)
* `.debug_gdb_scripts` sections are removed from `inputSections` due
to --strip-debug/--strip-all
* When processing --gc-sections, pieces of a SHF_MERGE section can be
marked live separately
`=>` segfault when marking liveness of a `.debug_gdb_scripts` which
is not split into pieces (because it is not in `inputSections`)
This patch circumvents the problem by not treating SHF_ALLOC
".debug*" as debug sections (to prevent --strip-debug's stripping)
(which is still useful on its own).

Before this CTL always allocated MAXPHYS-sized buffers, even for 4KB I/O,
that is even more overkill for MAXPHYS of 1MB. This change limits maximum
allocation to 512KB if MAXPHYS is bigger, plus if one is above 128KB, adds
new 128KB UMA zone for smaller I/Os. The patch factors out alloc/free,
so later we could make it use more zones or malloc() if we'd like.
