Enable DMI scanning on the MIPS architecture, this setups DMI identifiers
(dmi_system_id) for printing it out on task dumps and prepares DIMM entry
information (dmi_memdev_info) from the SMBIOS table. With this patch, the
driver can easily match various of mainboards.

In the SMBIOS reference specification, the table anchor string "_SM_" is
present in the address range 0xF0000 to 0xFFFFF on a 16-byte boundary,
but there exists a special case for Loongson platform, when call function
dmi_early_remap, it should specify the start address to 0xFFFE000 due to
it is reserved for SMBIOS and can be normally access in the BIOS.

This patch works fine on the Loongson 3A3000 platform which belongs to
MIPS architecture and has no influence on the other architectures such
as x86 and ARM.

Additionally, in order to avoid the unknown risks on the mips platform
which is not MACH_LOONGSON64, the DMI config is better to depend on
MACH_LOONGSON64. If other mips platform also needs this DMI feature in
the future, the "depends on" condition can be modified.

mt7621 SoC has its own 'ralink_soc_info' structure with some
information about the soc itself. Pcie controller and pcie phy
drivers for this soc which are still in staging git tree make uses
of 'soc_device_attribute' looking for revision 'E2' in order to
know if reset lines are or not inverted. This way of doing things
seems to be necessary in order to make things clean and properly.
Hence, introduce this 'soc_device' to be able to properly use those
attributes in drivers. Also set 'data' pointer points to the struct
'ralink_soc_info' to be able to export also current soc information
using this mechanism.

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.

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.

The Atheros 7/9xxx platform code is not a clock provider, and just needs
to call of_clk_init().

Hence it can include <linux/of_clk.h> instead of <linux/clk-provider.h>.

Clang does not support this option and errors out:

clang-11: error: unknown argument: '-mexplicit-relocs'

Clang does not appear to need this flag like GCC does because the jalr
check that was added in commit 976c23af ("mips: vdso: add build
time check that no 'jalr t9' calls left") passes just fine with

$ make ARCH=mips CC=clang CROSS_COMPILE=mipsel-linux-gnu- malta_defconfig arch/mips/vdso/

even before commit d3f703c4 ("mips: vdso: fix 'jalr t9' crash in
vdso code").

-mrelax-pic-calls has been supported since clang 9, which is the
earliest version that could build a working MIPS kernel, and it is the
default for clang so just leave it be.

Pull EDAC fixes from Borislav Petkov:
 "Two fixes for use-after-free and memory leaking in the EDAC core, by
  Robert Richter.

  Debug options like DEBUG_TEST_DRIVER_REMOVE, KASAN and DEBUG_KMEMLEAK
  unearthed issues with the lifespan of memory allocated by the EDAC
  memory controller descriptor due to misdesigned memory freeing, done
  partially by the EDAC core *and* the driver core, which is problematic
  to say the least.

  These two are minimal fixes to take care of stable - a proper rework
  is following which cleans up that mess properly"
