The macro that creates both the structure and the format displayed
to user space for the stack trace event was changed a while ago
to fix the parsing by user space tooling. But this change also modified

It looks like ia64 implements atomic_t as a 64-bit value and expects atomic_t
to be 64-bit aligned, but does nothing to ensure that.
For x86, atomic_t is a 32-bit value and atomic64_t is a 64-bit value, and
the definition of atomic64_t is overridden in a way that ensures
64-bit (8 byte) alignment:

V1->V2:
As suggested by Rob Herring:
This code provides architectures with a way to build command line
based on what is built in the kernel and what is handed over by the
bootloader, based on selected compile-time options.

v3:
- Addressed comments from Will
- Added capability to have src == dst
v4
The purpose of this series is to improve and enhance the
handling of kernel boot arguments.
Current situation is that most if not all architectures are using
similar options to do some manupulation on command line arguments:
- Prepend built-in arguments in front of bootloader provided arguments
-
This patch uses the new cmdline building function to
concatenate the of provided cmdline with built-in parts
based on compile-time options.

Use cmdline building function in EFI.
EFI cannot use pr_err() and doesn't have a .init.data section,
so use the __cmdline_build() internal function and provides
both a source and a destination.
Remove the handling of too long command lines as it is handled
by the generic CMDLINE.

Most architectures have similar boot command line manipulation
options. This patchs adds the definition in init/Kconfig, gated by
CONFIG_HAVE_CMDLINE that the architectures can select to use them.
CONFIG_CMDLINE_EXTEND is understood differently by architectures.
For some of them it appends built-i

There's only two users of strcpy and one is the command
line handling. The generic command line handling uses strlcpy
and it makes sense to convert this one other user to strlcpy to
keep prom_init size consistent.

During boot, x86 uses EFI driver. That driver is also used
by ARM.
In order to refactor the command line processing in that driver
in a following patch, rename CONFIG_CMDLINE_OVERRIDE by
CONFIG_CMDLINE_FORCE on the x86 in order to be similar
to ARM (and most other architectures).

This updates the powerpc code to use the new cmdline building function.
The cmdline_build() defines a temporary string in __initdata.
powerpc uses __prombss instead at the moment, so we must
call cmdline_build() with destination different from the source
to allow GCC to optimise the temporary stri
