Hi Masahiro, After merging the kbuild tree, today's linux-next build (x86_64 allmodconfig) produced these warnings: drivers/net/wireless/broadcom/brcm80211/brcmsmac/phy/phy_n.c: In function 'wlc_phy_workarounds_nphy_rev7': drivers/net/wireless/broadcom/brcm80211/brcmsmac/phy/phy_n.c:16563:1: warning: the frame size of 3136 bytes is larger than 2048 bytes [-Wframe-larger-than=] } ^ drivers/net/wireless/broadcom/brcm80211/brcmsmac/phy/phy_n.c: In function 'wlc_phy_workarounds_nphy_rev3': drivers/net/wireless/broadcom/brcm80211/brcmsmac/phy/phy_n.c:16905:1: warning: the frame size of 2872 bytes is larger than 2048 bytes [-Wframe-larger-than=] } ^ drivers/net/wireless/broadcom/brcm80211/brcmsmac/phy/phy_n.c: In function 'wlc_phy_cal_txiqlo_nphy': drivers/net/wireless/broadcom/brcm80211/brcmsmac/phy/phy_n.c:26033:1: warning: the frame size of 2432 bytes is larger than 2048 bytes [-Wframe-larger-than=] } ^ I have no idea what caused these warnings to appear ... nothing in those functions looks too bad. -- Cheers, Stephen Rothwell
