When b43legacy is compiled on the arm platform, the following errors are seen: CC [M] drivers/net/wireless/b43legacy/xmit.o In file included from include/net/dst.h:11, from drivers/net/wireless/b43legacy/xmit.c:31: include/net/dst_ops.h:28: error: expected ':', ',', ';', '}' or '__attribute__' before '____cacheline_aligned_in_smp' include/net/dst_ops.h: In function 'dst_entries_get_fast': include/net/dst_ops.h:33: error: 'struct dst_ops' has no member named 'pcpuc_entries' include/net/dst_ops.h: In function 'dst_entries_get_slow': include/net/dst_ops.h:41: error: 'struct dst_ops' has no member named 'pcpuc_entries' include/net/dst_ops.h: In function 'dst_entries_add': include/net/dst_ops.h:49: error: 'struct dst_ops' has no member named 'pcpuc_entries' include/net/dst_ops.h: In function 'dst_entries_init': include/net/dst_ops.h:55: error: 'struct dst_ops' has no member named 'pcpuc_entries' include/net/dst_ops.h: In function 'dst_entries_destroy': include/net/dst_ops.h:60: error: 'struct dst_ops' has no member named 'pcpuc_entries' make[4]: *** [drivers/net/wireless/b43legacy/xmit.o] Error 1 make[3]: *** [drivers/net/wireless/b43legacy] Error 2 make[2]: *** [drivers/net/wireless] Error 2 make[1]: *** [drivers/net] Error 2 make: *** [drivers] Error 2 The cause is a missing include of <linux/cache.h>, which is present for i386 and x86_64 architectures, but not for arm.
