arch/arc/Makefile overrides -O2 with -O3. This is the only user of
ARCH_CFLAGS. There is no user of ARCH_CPPFLAGS or ARCH_AFLAGS.
My plan is to remove ARCH_{CPP,A,C}FLAGS after refactoring the ARC
Makefile.
Currently, ARC has no way to enable -Wmaybe-uninitialized because both
-O3 and -Os disable it. Enabling it will be useful for compile-testing.
This commit allows allmodconfig (, which defaults to -O2) to enable it.
Add CONFIG_CC_OPTIMIZE_FOR_PERFORMANCE_O3=y to all the defconfig files
in arch/arc/configs/ in order to keep the current config settings.

This Kconfig option was removed during v4.19 development in commit
771c035372 ("deprecate the '__deprecated' attribute warnings entirely
and for good") so there's no point to keep it in defconfigs any longer.
FWIW defconfigs were patched with:
--------------------------->8----------------------
find . -name *_defconfig -exec sed -i '/CONFIG_ENABLE_WARN_DEPRECATED/d' {} \;
--------------------------->8----------------------

By default NFSv3 doesn't support ACL (Access Control Lists)
which might be quite convenient to have so that
mounted NFS behaves exactly as any other local file-system.
In particular missing support of ACL makes umask useless.
This among other thigs fixes Glibc's "nptl/tst-umask1".

SWAP support on ARC was fixed earlier by
commit 6e3761145a ("ARC: Fix CONFIG_SWAP")
so now we may safely enable it on platforms that
have external media like USB and SD-card.
Note: it was already allowed for HSDK

- Remove CONFIG_DEFAULT_HOSTNAME from defconfigs
There's no reason to set the same hostname to all ARC boards
by default. It usually gets overwritten by init scripts anyways.
- Remove disabled CONFIG_DEVKMEM from defconfigs
It is disabled by default

We used to have pre-set CONFIG_INITRAMFS_SOURCE with local path
to intramfs in ARC defconfigs. This was quite convenient for
in-house development but not that convenient for newcomers
who obviusly don't have folders like "arc_initramfs" next to
the Linux source tree. Which leads to quite surprising failure
of defconfig building:
------------------------------->8-----------------------------
../scripts/gen_initramfs_list.sh: Cannot open '../../arc_initramfs_hs/'
../usr/Makefile:57: recipe for target 'usr/initramfs_data.cpio.gz' failed
make[2]: *** [usr/initramfs_data.cpio.gz] Error 1
------------------------------->8-----------------------------
So now when more and more people start to deal with our defconfigs
let's make their life easier with removal of CONFIG_INITRAMFS_SOURCE.

Commit 92e5aae457 "kernel/watchdog: split up config options"

instead of the latter to be selected itself.
We need to adjust our defconfigs accordingly.

As mentioned in LTP's README.ARC:
------------->8------------
Requirements for the environment
* Linux must be built with support of loop block devices. Thus it's
necessary to enable these Linux kernel options:
CONFIG_BLK_DEV
CONFIG_BLK_DEV_LOOP
------------->8------------
enabling loop block devices.
That among other things lead to additional 10 fatal signals
appearing during LTP run.

The problem is with CONFIG_CPU_BIG_ENDIAN=y we still needed .config
fixup to override the the defconfig prefix to arceb-linux-
So remove these from defconfig and let user pass this via CROSS_COMPILE
environment var or use the default for ENDIAN (per previous patch)
No other arch carries them in defconfigs anyways !

Even though DEVTMPFS is required when our pre-built initramfs
is used it is not the case in general. It is perfectly possible
to use initramfs with device nodes already populated or there
could be other usages, see discussion below for more detials:
http://thread.gmane.org/gmane.comp.embedded.openwrt.devel/37819/focus=37821
This change removes mentioned dependency from arch/arc/Kconfig
updating instead those defconfigs that are usually used with this
kind of pre-build initramfs.
And while at it all touched defconfigs were regenerated via
savedefconfig and some options were removed:
* USB is selected by other options implicitly
* VGA_CONSOLE is disableb for ARC since
031e29b587
* EXT3_FS automatically selects EXT4_FS
* MTDxxx and JFFS2_FS make no sense for AXS because
AXS NAND controller is not upstreamed
* NET_OSCI_LAN is not in upstream as well
* ARCPGU_xxx options make no sense because ARC PGU is not yet
in upstream and when it gets there all config options would
be taken from devicetree

When building kernel with buildroot built toolchain, CROSS_COMPILE
currently needs adjustment even if minor. This is because the defconfigs
prefer "arc-linux-uclibc-" prefix from hand built (non buildroot) toolchain
while buildroot provides "arc-buildroot-linux-uclibc-"
To avoid this use the common "arc-linux-" prefix which is provided by
buildroot and has also been in hand built tools for quite some time.
