40b664f64b [PowerPC] More relocation fixes
It turns out relocating the symbol table itself can cause issues, like fbt
crashing because it applies the offsets to the kernel twice.

This had been previously brought up in rS333447 when the stoffs hack was
added, but I had been unaware of this and reimplemented symtab relocation.

Instead of relocating the symbol table, keep track of the relocation base
in ddb, so the ddb symbols behave like the kernel linker-provided symbols.

This is intended to be NFC on platforms other than PowerPC, which do not
use fully relocatable kernels. (The relbase will always be 0)

 * Remove the rest of the stoffs hack.
 * Remove my half-baked displace_symbol_table() function.
 * Extend ddb initialization to cope with having a relocation offset on the
   kernel symbol table.
 * Fix my kernel-as-initrd hack to work with booke64 by using a temporary
   mapping to access the data.
 * Fix another instance of __powerpc__ that is actually RELOCATABLE_KERNEL.
 * Change the behavior or X_db_symbol_values to apply the relocation base
   when updating valp, to match link_elf_symbol_values() behavior.

852c303b61 copystr(9): Move to deprecate (attempt #2)
This reapplies logical r360944 and r360946 (reverting r360955), with fixed
copystr() stand-in replacement macro.  Eventually the goal is to convert
consumers and kill the macro, but for a first step it helps if the macro is
correct.

Prior commit message:

Unlike the other copy*() functions, it does not serve to copy from one
address space to another or protect against potential faults.  It's just
an older incarnation of the now-more-common strlcpy().

Add a coccinelle script to tools/ which can be used to mechanically
convert existing instances where replacement with strlcpy is trivial.
In the two cases which matched, fuse_vfsops.c and union_vfsops.c, the
code was further refactored manually to simplify.

Replace the declaration of copystr() in systm.h with a small macro
wrapper around strlcpy (with correction from brooks@ -- thanks).

Remove N redundant MI implementations of copystr.  For MIPS, this
entailed inlining the assembler copystr into the only consumer,
copyinstr, and making the latter a leaf function.

49439183ce Convert arm's physmem interface to MI code
The arm_physmem interface found in arm's MD code provides a convenient
set of routines for adding/excluding physical memory regions and
initializing important kernel globals such as Maxmem, realmem,
phys_avail[], and dump_avail[]. It is especially convenient for FDT
systems, since we can use FDT parsing functions and pass the result
directly to one of these physmem routines. This interface is already in
use on arm and arm64, and can be used to simplify this early
initialization on RISC-V as well.

This requires only a couple trivial changes:
  - Move arm_physmem_kernel_addr to arm/machdep.c. It is unused on arm64,
    and manipulated entirely in arm MD code.
  - Convert arm32_btop/arm64_btop to atop. This is equivalently defined
    on all architectures.
  - Drop the "arm" prefix.

While the two debugging services share some fields in struct proc,
they each use dedicated fields and separate code.  This results in
extra complexity to support a feature that hasn't been enabled in the

ca0ec73c11 Expand generic subword atomic primitives
The goal of this change is to make the atomic_load_acq_{8,16},
atomic_testandset{,_acq}_long, and atomic_testandclear_long primitives
available in MI-namespace.

The second goal is to get this draft out of my local tree, as anything that
requires a full tinderbox is a big burden out of tree.  MD specifics can be
refined individually afterwards.

The generic implementations may not be ideal for your architecture; feel
free to implement better versions.  If no subword_atomic definitions are
needed, the include can be removed from your arch's machine/atomic.h.
Generic definitions are guarded by defined macros of the same name.  To
avoid picking up conflicting generic definitions, some macro defines are
added to various MD machine/atomic.h to register an existing implementation.

Include _atomic_subword.h in arm and arm64 machine/atomic.h.

For some odd reason, KCSAN only generates some versions of primitives.
Generate the _acq variants of atomic_load.*_8, atomic_load.*_16, and
atomic_testandset.*_long.  There are other questionably disabled primitives,
but I didn't run into them, so I left them alone.  KCSAN is only built for
amd64 in tinderbox for now.

Add atomic_subword implementations of atomic_load_acq_{8,16} implemented
using masking and atomic_load_acq_32.

Add generic atomic_subword implementations of atomic_testandset_long(),
atomic_testandclear_long(), and atomic_testandset_acq_long(), using
atomic_fcmpset_long() and atomic_fcmpset_acq_long().

On x86, add atomic_testandset_acq_long as an alias for
atomic_testandset_long.

6b29cf3343 Move arm back to having one LINT
Now that armv5 is gone, we no longer need multiple LINT files. Kill
the odd-ball support here. From now on, we just have LINT built from
notes like all the other platforms. Keep the removal of LINT-V5/7
to remove stale files for a while still..

is gone, it can be retired too.
