The compressed payload is not necesarily 4-byte aligned, at least when
compiling with Clang. In that case, the 4-byte value appended to the
compressed payload that corresponds to the uncompressed kernel image
size must be read using get_unaligned_le().
This fixes Clang-built kernels not booting on MIPS (tested on a Ingenic
JZ4770 board).
Fixes: b8f54f2cde78 ("MIPS: ZBOOT: copy appended dtb to the end of the kernel")

Should it be get_unaligned_le32()?

Hi Paul, thanks for the patch (and for testing with Clang)!
Alternatively, we could re-align __image_end to the next 4B multiple
via:
diff --git a/arch/mips/boot/compressed/ld.script
b/arch/mips/boot/compressed/ld.script
index 0ebb667274d6..349919eff5fb 100644
--- a/arch/mips/boot/compressed/ld.script
+++ b/arch/mips/boot/compressed/ld.script
@@ -27,6 +27,7 @@ SECTIONS
/* Put the compressed image here */
__image_begin = .;
*(.image)
+ . = ALIGN(4);
__image_end = .;
CONSTRUCTORS
. = ALIGN(16);
The tradeoff being up to 3 wasted bytes of padding in the compressed
image, vs fetching one value slower (assuming unaligned loads are
slower than aligned loads MIPS, IDK). I doubt decompress_kernel is
called repeatedly, so let's take the byte saving approach of yours by
using unaligned loads!

Actually that would not work (I did try that), since the 4-byte size
appended to the compressed payload is inside the *(.image) section. The
code that appends it (in scripts/Makefile.lib, I think) doesn't seem to
take care about aligning it to a 4-byte offset. I have no idea why it
does with GCC and doesn't with Clang, and I have no idea why the
compressed payload's size isn't aligned either.

gives me following error
arch/mips/boot/compressed/decompress.c:120:16: error: implicit declaration of function ‘get_unaligned_le32’ [-Werror=implicit-function-declaration]
image_size = get_unaligned_le32((void *)&__image_end - 4);
I've added
#include <asm/unaligned.h>
which fixes the compile error, but I'm wondering why the patch compiled
for you ?

No idea - but it does compile fine without the include here. Probably a
defconfig difference.

# CONFIG_KERNEL_LZO is not set
# CONFIG_KERNEL_LZ4 is not set
this makes the difference. Both decompress.c files include asm/unaligned.h.
I've added the #include, fixed the get_unaligned_le32 in the description
and applied it to mips-fixes.
