[PATCH] um: add 2 missing libs to fix various build errors
by Randy Dunlap
Fix many build errors (at least 18 build error reports) for uml on i386
by adding 2 more library object files. All missing symbols are
either cmpxchg8b_emu or atomic*386.
Here are a few examples of the build errors that are eliminated:
/usr/bin/ld: core.c:(.text+0xd83): undefined reference to `cmpxchg8b_emu'
/usr/bin/ld: core.c:(.text+0x2bb2): undefined reference to `atomic64_add_386'
/usr/bin/ld: core.c:(.text+0x2c5d): undefined reference to `atomic64_xchg_386'
syscall.c:(.text+0x2f49): undefined reference to `atomic64_set_386'
/usr/bin/ld: syscall.c:(.text+0x2f54): undefined reference to `atomic64_set_386'
syscall.c:(.text+0x33a4): undefined reference to `atomic64_inc_386'
/usr/bin/ld: syscall.c:(.text+0x33ac): undefined reference to `atomic64_inc_386'
/usr/bin/ld: net/ipv4/inet_timewait_sock.o: in function `inet_twsk_alloc':
inet_timewait_sock.c:(.text+0x3d1): undefined reference to `atomic64_read_386'
/usr/bin/ld: inet_timewait_sock.c:(.text+0x3dd): undefined reference to `atomic64_set_386'

/usr/bin/ld: inet_connection_sock.c:(.text+0x1d80): undefined reference to `atomic64_set_386'
/usr/bin/ld: net/ipv4/tcp_input.o: in function `inet_reqsk_alloc':

My UML on i386 build environment is br0ken so this is not tested other
than to see that the .o files are built as expected.
If someone can test/verify it, please respond. Thanks.

Hi Michel,
Thank you for the patch! Yet something to improve:
[auto build test ERROR on tip/x86/mm]
[also build test ERROR on arm64/for-next/core linus/master v5.12]
[cannot apply to hnaz-linux-mm/master next-20210430]
[If your patch is applied to the wrong git tree, kindly drop us a note.
And when submitting patch, we suggest to use '--base' as documented in
