Masahiro Yamada 15f5db60a1 kbuild,arc: add CONFIG_CC_OPTIMIZE_FOR_PERFORMANCE_O3 for ARC
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.

Alexey Brodkin 3337d5cfe5 configs: get rid of obsolete CONFIG_ENABLE_WARN_DEPRECATED
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----------------------

Eugeniy Paltsev 493a2f8124 ARC: enable uboot support unconditionally
After reworking U-boot args handling code and adding paranoid
arguments check we can eliminate CONFIG_ARC_UBOOT_SUPPORT and
enable uboot support unconditionally.

For JTAG case we can assume that core registers will come up
reset value of 0 or in worst case we rely on user passing
'-on=clear_regs' to Metaware debugger.

Alexey Brodkin 6b04114f6f arc: [devboards] Add support of NFSv3 ACL
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".

Alexey Brodkin 4051c323c5 ARC: configs: cleanup
- 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

Alexey Brodkin 9583833e9e ARC: [*defconfig] Reenable soft lock-up detector
Commit 92e5aae457 "kernel/watchdog: split up config options"
introduced SOFTLOCKUP_DETECTOR which selects LOCKUP_DETECTOR
instead of the latter to be selected itself.

We need to adjust our defconfigs accordingly.

Vineet Gupta 2d746eeb4f ARC: [*defconfig] No need to specify CONFIG_CROSS_COMPILE
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 !

sujayraaj 17c4fbaf1a ARC: switch to arc-linux- CROSS_COMPILE prefix across all configs
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.
