https://git.stealer.net/cgit.cgi/user/sven/linux.git/atom?h=v6.18.12023-06-08T19:27:20Zkallsyms: make kallsyms_show_value() as generic function2023-06-08T19:27:20ZManinder Singhmaninder1.s@samsung.com2023-06-08T03:31:19Zurn:sha1:0eeaf1eb40a34fddd1d568a9b32c3d6669238743
This change makes function kallsyms_show_value() as
generic function without dependency on CONFIG_KALLSYMS.
Now module address will be displayed with lsmod and /proc/modules.
Earlier:
=======
/ # insmod test.ko
/ # lsmod
test 12288 0 - Live 0x0000000000000000 (O) // No Module Load address
/ #
With change:
==========
/ # insmod test.ko
/ # lsmod
test 12288 0 - Live 0xffff800000fc0000 (O) // Module address
/ # cat /proc/modules
test 12288 0 - Live 0xffff800000fc0000 (O)

kallsyms: move kallsyms_show_value() out of kallsyms.c2023-06-08T19:27:20ZManinder Singhmaninder1.s@samsung.com2023-06-08T03:31:18Zurn:sha1:b06e9318bfd03f531b918bd27b63f1eb88c21729
function kallsyms_show_value() is used by other parts
like modules_open(), kprobes_read() etc. which can work in case of
!KALLSYMS also.
e.g. as of now lsmod do not show module address if KALLSYMS is disabled.
since kallsyms_show_value() defination is not present, it returns false
in !KALLSYMS.
/ # lsmod
test 12288 0 - Live 0x0000000000000000 (O)
So kallsyms_show_value() can be made generic
without dependency on KALLSYMS.
Thus moving out function to a new file ksyms_common.c.
With this patch code is just moved to new file
and no functional change.
