Thank you.
 
In /usr/src/linux/.config, we can see that
"CONFIG_KALLSYMS=y" is included in the General setup
section like the following: 
 
#
# General setup
#
CONFIG_SWAP=y
CONFIG_SYSVIPC=y
CONFIG_POSIX_MQUEUE=y
CONFIG_BSD_PROCESS_ACCT=y
CONFIG_SYSCTL=y
CONFIG_AUDIT=y
CONFIG_AUDITSYSCALL=y
CONFIG_LOG_BUF_SHIFT=17
CONFIG_HOTPLUG=y
# CONFIG_IKCONFIG is not set
# CONFIG_EMBEDDED is not set
CONFIG_KALLSYMS=y
CONFIG_FUTEX=y
CONFIG_EPOLL=y
CONFIG_IOSCHED_NOOP=y
CONFIG_IOSCHED_AS=y
CONFIG_IOSCHED_DEADLINE=y
CONFIG_IOSCHED_CFQ=y
CONFIG_CC_OPTIMIZE_FOR_SIZE=y
 
But, when we run 'make menuconfig', we can only see
that the General setup section only contains the
following items:
  
  [*] Support for paging of anonymous memory (swap)   

  [*] System V IPC                                 
  [*] POSIX Message Queues                         
  [*] BSD Process Accounting                          
   
  [*] Sysctl support                                  
     
  [*] Auditing support                                
     
  [*]   Enable system-call auditing support           
      
  (17) Kernel log buffer size (16 => 64KB, 17 =>
128KB)        
  [*] Support for hot-pluggable devices               
          
  [ ] Kernel .config support                          
         
  [ ] Configure standard kernel features (for small
systems)  ---> 
  [*] Optimize for size                               
 
Then, It seems that there is no place to disable
CONFIG_KALLSYMS (i.e. turn 'CONFIG_KALLSYMS=y' to
'CONFIG_KALLSYMS is not set'), How can I turn off the
'CONFIG_KALLSYMS' item?? Is CONFIG_KALLSYMS=y set
automatically by system?

Thanks,
