+Subject: [PATCH] MIPS: select CPU_MIPS64 for remaining MIPS64 CPUs
+
+The CPU_MIPS64 and CPU_MIPS32 variables are supposed to be able to
+distinguish broadly between 64-bit and 32-bit MIPS CPUs. However, they
+weren't selected by the specialty CPUs, Octeon and Loongson, which meant
+it was possible to hit a weird state of:
+
+ MIPS=y, CONFIG_64BIT=y, CPU_MIPS64=n
+
+This commit rectifies the issue by having CPU_MIPS64 be selected when
+the missing Octeon or Loongson models are selected.

+Subject: [PATCH] MIPS: zboot: put appended dtb into a section
+
+This will make a separated section for dtb appear in ELF, and we can
+then use objcopy to patch a dtb into vmlinuz when RAW_APPENDED_DTB
+is set in kernel config.
+
+command to patch a dtb:
+objcopy --set-section-flags=.appended_dtb=alloc,contents \
+ --update-section=.appended_dtb=<target>.dtb vmlinuz vmlinuz-dtb
