fe82de91af Revert "MIPS: Octeon: Remove special handling of CONFIG_MIPS_ELF_APPENDED_DTB=y"
This reverts commit d9df9fb901.

For the OCTEON boards, it need to patch the built-in DTB before using
it. Previously it judges if it is a built-in DTB by checking
fw_passed_dtb. But after commit 37e5c69ffd ("MIPS: head.S: Init
fw_passed_dtb to builtin DTB", the fw_passed_dtb is initialized even
when using built-in DTB. This causes the OCTEON boards boot broken due
to an unpatched built-in DTB is used. Revert the commit d9df9fb901 to
restore the codes before the fw_passed_dtb is used and then fix this
issue.

Fixed: 37e5c69ffd ("MIPS: head.S: Init fw_passed_dtb to builtin DTB")

7b490a8ab0 MIPS: OCTEON: fix unreachable code in octeon_irq_init_ciu
The type of 'r' in octeon_irq_init_ciu is 'unsigned int', so 'r < 0'
can't be true.

Fix this by change the type of 'r' and 'i' from 'unsigned int'
to 'int'. As 'i' won't be negative, this change works.

cbab54d9c2 MIPS: No need to check CPU 0 in {loongson3,bmips,octeon}_cpu_disable()
After commit 9cce844abf ("MIPS: CPU#0 is not hotpluggable"),
c->hotpluggable is 0 for CPU 0 and it will not generate a control
file in sysfs for this CPU:

[root@linux loongson]# cat /sys/devices/system/cpu/cpu0/online
cat: /sys/devices/system/cpu/cpu0/online: No such file or directory
[root@linux loongson]# echo 0 > /sys/devices/system/cpu/cpu0/online
bash: /sys/devices/system/cpu/cpu0/online: Permission denied

So no need to check CPU 0 in {loongson3,bmips,octeon}_cpu_disable(),
just remove them.

a24d22b225 crypto: sha - split sha.h into sha1.h and sha2.h
Currently <crypto/sha.h> contains declarations for both SHA-1 and SHA-2,
and <crypto/sha3.h> contains declarations for SHA-3.

This organization is inconsistent, but more importantly SHA-1 is no
longer considered to be cryptographically secure.  So to the extent
possible, SHA-1 shouldn't be grouped together with any of the other SHA
versions, and usage of it should be phased out.

Therefore, split <crypto/sha.h> into two headers <crypto/sha1.h> and
<crypto/sha2.h>, and make everyone explicitly specify whether they want
the declarations for SHA-1, SHA-2, or both.

This avoids making the SHA-1 declarations visible to files that don't
want anything to do with SHA-1.  It also prepares for potentially moving
sha1.h into a new insecure/ or dangerous/ directory.

b10d6bca87 arch, drivers: replace for_each_membock() with for_each_mem_range()
There are several occurrences of the following pattern:

	for_each_memblock(memory, reg) {
		start = __pfn_to_phys(memblock_region_memory_base_pfn(reg);
		end = __pfn_to_phys(memblock_region_memory_end_pfn(reg));

		/* do something with start and end */
	}

Using for_each_mem_range() iterator is more appropriate in such cases and
allows simpler and cleaner code.

2aaba014b5 crypto: lib/sha1 - remove unnecessary includes of linux/cryptohash.h
<linux/cryptohash.h> sounds very generic and important, like it's the
header to include if you're doing cryptographic hashing in the kernel.
But actually it only includes the library implementation of the SHA-1
compression function (not even the full SHA-1).  This should basically
never be used anymore; SHA-1 is no longer considered secure, and there
are much better ways to do cryptographic hashing in the kernel.

Most files that include this header don't actually need it.  So in
preparation for removing it, remove all these unneeded includes of it.

5c6bd5de3c Main MIPS changes for v5.4:
- boot_mem_map is removed, providing a nice cleanup made possible by the
   recent removal of bootmem.
 
 - Some fixes to atomics, in general providing compiler barriers for
   smp_mb__{before,after}_atomic plus fixes specific to Loongson CPUs or
   MIPS32 systems using cmpxchg64().
 
 - Conversion to the new generic VDSO infrastructure courtesy of Vincenzo
   Frascino.
 
 - Removal of undefined behavior in set_io_port_base(), fixing the
   behavior of some MIPS kernel configurations when built with recent
   clang versions.
 
 - Initial MIPS32 huge page support, functional on at least Ingenic SoCs.
 
 - pte_special() is now supported for some configurations, allowing among
   other things generic fast GUP to be used.
 
 - Miscellaneous fixes & cleanups.
 
 And platform specific changes:
 
 - Major improvements to Ingenic SoC support from Paul Cercueil, mostly
   enabled by the inclusion of the new TCU (timer-counter unit) drivers
   he's spent a very patient year or so working on. Plus some fixes for
   X1000 SoCs from Zhou Yanjie.
 
 - Netgear R6200 v1 systems are now supported by the bcm47xx platform.
 
 - DT updates for BMIPS, Lantiq & Microsemi Ocelot systems.

MIPS: Annotate fall-through in Cavium Octeon code
There's an intentional switch case fall-through in Cavium Octeon USB
code, which triggers compile errors with -Wimplicit-fallthrough due to
-Werror being enabled for arch/mips.

This can be encountered when building cavium_octeon_defconfig.

Fix the build issue by annotating the intentional fall-through.
