x86/debug: Remove ancient debugging noise from boot log when starting cpus
Printing the "start_ip" for every secondary cpu is very noisy on
a large system - and doesn't add any value. Drop this message.
Console log before:
Booting Node 0, Processors #1
smpboot cpu 1: start_ip = 96000
#2
smpboot cpu 2: start_ip = 96000
#3
smpboot cpu 3: start_ip = 96000
#4
smpboot cpu 4: start_ip = 96000
...
#31
smpboot cpu 31: start_ip = 96000
Brought up 32 CPUs
Console log after:
Booting Node 0, Processors #1 #2 #3 #4 #5 #6 #7 Ok.
Booting Node 1, Processors #8 #9 #10 #11 #12 #13 #14 #15 Ok.
Booting Node 0, Processors #16 #17 #18 #19 #20 #21 #22 #23 Ok.
Booting Node 1, Processors #24 #25 #26 #27 #28 #29 #30
#31 Brought up 32 CPUs
