To count stack usage of push {*, fp, ip, lr, pc} instruction in ARM,
if FRAME POINTER is enabled.
e.g. c01f0d48: e92ddff0 push {r4, r5, r6, r7, r8, r9, sl, fp, ip, lr, pc}
c01f0d50 <Y>:
c01f0d44: e1a0c00d mov ip, sp
c01f0d48: e92ddff0 push {r4, r5, r6, r7, r8, r9, sl, fp, ip, lr, pc}
c01f0d4c: e24cb004 sub fp, ip, #4
c01f0d50: e24dd094 sub sp, sp, #448 ; 0x1C0
$ cat dump | scripts/checkstack.pl arm
0xc01f0d50 Y []: 448
added subroutine frame work for this.
After change:
0xc01f0d500 Y []: 492

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
