From a730af6e3114d549555f4b130c216bad1c3aa80e Mon Sep 17 00:00:00 2001 From: Randy Dunlap Date: Sun, 4 Apr 2021 11:20:44 -0700 Subject: um: Add 2 missing libs to fix various build errors 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: net/ipv4/inet_connection_sock.o: in function `inet_csk_clone_lock': 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' /usr/bin/ld: net/mac80211/wpa.o: in function `ieee80211_crypto_tkip_encrypt': wpa.c:(.text+0x739): undefined reference to `atomic64_inc_return_386' Signed-off-by: Randy Dunlap Reported-by: kernel test robot Cc: Brendan Jackman Cc: Alexei Starovoitov Cc: kbuild-all@lists.01.org Cc: Jeff Dike Cc: Richard Weinberger Cc: Anton Ivanov Cc: linux-um@lists.infradead.org Cc: Johannes Berg Cc: Johannes Berg Signed-off-by: Richard Weinberger --- arch/x86/um/Makefile | 1 + 1 file changed, 1 insertion(+) (limited to 'arch/x86/um/Makefile') diff --git a/arch/x86/um/Makefile b/arch/x86/um/Makefile index 77f70b969d14..5ccb18290d71 100644 --- a/arch/x86/um/Makefile +++ b/arch/x86/um/Makefile @@ -21,6 +21,7 @@ obj-y += checksum_32.o syscalls_32.o obj-$(CONFIG_ELF_CORE) += elfcore.o subarch-y = ../lib/string_32.o ../lib/atomic64_32.o ../lib/atomic64_cx8_32.o +subarch-y += ../lib/cmpxchg8b_emu.o ../lib/atomic64_386_32.o subarch-y += ../kernel/sys_ia32.o else -- cgit v1.2.3
