Subject: [PATCH] um: add 2 missing libs to fix various build errors
Date: Sun, 4 Apr 2021 11:20:44 -0700 [thread overview]
Message-ID: <20210404182044.9918-1-rdunlap@infradead.org> (raw)
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'

inet_connection_sock.c:(.text+0x1d74): undefined reference to `atomic64_read_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':
tcp_input.c:(.text+0xa345): undefined reference to `atomic64_set_386'

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.
