Analyze and fix the following issue in the Linux kernel code: MIPS: Calculate VMLINUZ_LOAD_ADDRESS based on the length of vmlinux.bin
Problem Details: Fix VMLINUZ_LOAD_ADDRESS calculation to be based on the length of vmlinux.bin, the actual uncompressed kernel binary. Previously it was based on the length of KBUILD_IMAGE (the unstripped ELF vmlinux), which is bigger than vmlinux.bin. As a result, vmlinuz was loaded into a memory address higher then...
