+Subject: Kbuild: provide a __UNIQUE_ID for clang
+
+From: Arnd Bergmann <arnd@arndb.de>
+
+commit b41c29b0527c7fd6a95d0f71274abb79933bf960 upstream.
+
+The default __UNIQUE_ID macro in compiler.h fails to work for some drivers:
+
+drivers/net/wireless/broadcom/brcm80211/brcmfmac/sdio.c:615:1: error: redefinition of
+ '__UNIQUE_ID_firmware615'
+BRCMF_FW_NVRAM_DEF(4354, "brcmfmac4354-sdio.bin", "brcmfmac4354-sdio.txt");
+
+This adds a copy of the version we use for gcc-4.3 and higher, as the same
+one works with all versions of clang that I could find in svn (2.6 and higher).
