There are some common header files which are referenced locally
with #includenext method, includenext is tricky method and only
used on mips platform.
This patech removes includenext method, replace it with defailed
pathname prefix for header files.
This patch passes to compile on all mips platform with defconfig,
and is verified on my loongson64 box.
Changes:
--------
v2:
- Fix compiling issue on malta platform

Some userland application/program runtime/dynamic loaded need to
know about the current ISA level to use the best runtime.
While kernel doesn't provides this info.
ELF_PLATFORM only provides some info about the CPU, with very few info,
for example, the value is "mips" for both 24Kc and P6600.
Currently ELF_BASE_PLATFORM is not used by MIPS (only by powerpc).
So we cant set its value as:
mips2, mips3, mips4, mips5,
mips32, mips32r2, mips32r6
mips64, mips64r2, mips64r6
Then in userland, we can get it by:
getauxval(AT_BASE_PLATFORM)
The only problem is that it seems has different defination than ppc:
on ppc, it is the mircoarchitecture
while now we use it as ISA level on MIPS.

Zephyr secondary cache is 256KB, 128B lines. 32B sectors. A secondary cache
line can contain two instruction cache lines (64B), or four data cache
lines (32B). Hardware prefetch Cache detects stream access, and prefetches
ahead of processor access. Add support to invalidate BMIPS5000 cpu zephyr
secondary cache module (ZSCM) on DMA from device so that data returned is
coherent during DMA read operations.

Recently all usages of setup_irq() was replaced by request_irq().
request_irq() does a few sanity checks that were not done in
setup_irq(), if they fail irq registration will fail. One of the check
is to ensure that non-NULL dev_id is passed in the case of shared irq.
This caused malta on qemu to hang.
Fix it by passing handler as dev_id to all request_irq()'s that are
shared. For sni, instead of passing non-NULL dev_id, remove shared irq
flags.

request_irq() is preferred over setup_irq(). Invocations of setup_irq()
occur after memory allocators are ready.
Per tglx[1], setup_irq() existed in olden days when allocators were not
ready by the time early interrupts were initialized.
Hence replace setup_irq() by request_irq().
remove_irq() has been replaced by free_irq() as well.
There were build error's during previous version, couple of which was
reported by kbuild test robot <lkp@intel.com> of which one was reported
by Thomas Bogendoerfer <tsbogend@alpha.franken.de> as well. There were a
few more issues including build errors, those also have been fixed.

Default printk log level is KERN_WARNING. This makes automatic log

Remove some redundant assignments, that have no effect on
'make jazz_defconfig':
CONFIG_INET_XFRM_MODE_TRANSPORT=m
CONFIG_INET_XFRM_MODE_TUNNEL=m
CONFIG_CRYPTO_HMAC=y
Also drop the settings relating to crypto, wireless, advanced
networking etc. The Kconfig defaults for these options are fine.
This reduces the size of vmlinux so it can be launched by
"NetBSD/arc Bootstrap, Revision 1.1", which is conveniently available
on NetBSD/arc 5.1 ISO images.

CONFIG_IOSCHED_DEADLINE, CONFIG_IOSCHED_CFQ and CONFIG_DEFAULT_NOOP are

The IOSCHED_DEADLINE was replaced by MQ_IOSCHED_DEADLINE and it will be
now enabled by default (along with MQ_IOSCHED_KYBER).
The BFQ_GROUP_IOSCHED is the only multiqueue scheduler which comes with
group scheduling so select it in configs previously choosing
CFQ_GROUP_IOSCHED.

sizeof(buf), but buf is a pointer argument of the function. The hex
array is meant to contain hexadecimal representation of the bin array.

If CONFIG_QFMT_V2 is not enabled, but CONFIG_QUOTA is enabled, when a
user tries to mount a file system with the quota or project quota
enabled, the kernel will emit a very confusing messsage:
EXT4-fs warning (device vdc): ext4_enable_quotas:5914: Failed to enable quota tracking (type=0, err=-3). Please run e2fsck to fix.
EXT4-fs (vdc): mount failed
We will now report an explanatory message indicating which kernel
configuration options have to be enabled, to avoid customer/sysadmin
confusion.

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]
This issue was found with the help of Coccinelle.
