Subject: [PATCH] powerpc/64s: Make boot look nice(r)

From: Nicholas Piggin <[email-masked]>
Date: Thu, 16 May 2019 12:04:37 +1000

Radix boot looks like this:

 -----------------------------------------------------
 phys_mem_size     = 0x200000000
 dcache_bsize      = 0x80
 icache_bsize      = 0x80
 cpu_features      = 0x0000c06f8f5fb1a7
   possible        = 0x0000fbffcf5fb1a7
   always          = 0x00000003800081a1
 cpu_user_features = 0xdc0065c2 0xaee00000
 mmu_features      = 0xbc006041
 firmware_features = 0x0000000010000000
 hash-mmu: ppc64_pft_size    = 0x0
 hash-mmu: kernel vmalloc start   = 0xc008000000000000
 hash-mmu: kernel IO start        = 0xc00a000000000000
 hash-mmu: kernel vmemmap start   = 0xc00c000000000000
 -----------------------------------------------------

Fix:

 -----------------------------------------------------
 phys_mem_size     = 0x200000000
 dcache_bsize      = 0x80
 icache_bsize      = 0x80
 cpu_features      = 0x0000c06f8f5fb1a7
   possible        = 0x0000fbffcf5fb1a7
   always          = 0x00000003800081a1
 cpu_user_features = 0xdc0065c2 0xaee00000
 mmu_features      = 0xbc006041
 firmware_features = 0x0000000010000000
 vmalloc start     = 0xc008000000000000
 IO start          = 0xc00a000000000000
 vmemmap start     = 0xc00c000000000000
