Xingxing Su 8b3165e545 MIPS: Enable GCOV
Enable gcov profiling of the entire kernel on mips. Required changes
include disabling profiling for:

* arch/kernel/boot/compressed: not linked to main kernel.

Lightly tested on Loongson 3A3000 an 3A4000, seems to work as expected.

without "GCOV_PROFILE := n" in compressed Makefile,
build errors as follows:
...
ld: arch/mips/boot/compressed/string.o:(.data+0x88):
 undefined reference to `__gcov_merge_add'
ld: arch/mips/boot/compressed/string.o:
 in function `_GLOBAL__sub_I_00100_0_memcpy':
string.c:(.text.startup+0x4): undefined reference to `__gcov_init'
ld: arch/mips/boot/compressed/string.o:
 in function `_GLOBAL__sub_D_00100_1_memcpy':
string.c:(.text.exit+0x0): undefined reference to `__gcov_exit'

README

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.
