Hi I tested it on my phone, >From log: <4>[ 0.000000] INITRD unalign phys address:0x02000000+0x0022fb0e <4>[ 0.000000] INITRD aligned phys address:0x02000000+0x00230000 <4>[ 0.579474] free_initrd_mem: free pfn:8192---8752 The tail address is not aligned for most initrd image, This page will not be freed and lost . This patch have a limitation that the tail page's not used Part should not be reserved by any other driver, And must be memory . This is true for most bootloaders , And we will print error if it is false .
