It may happen, for example when querying a PHB interrupt # while the PHB is in an error state. # # In that case, we should consider the interrupt to be invalid when # checking its state in the irq_get_irqchip_state() handler. # # Fixes: da15c03b047d ("powerpc/xive: Implement get_irqchip_state method for XIVE to fix shutdown race") # Cc: stable@vger.kernel.org # v5.4+ # Signed-off-by: Frederic Barrat # [clg: wrote a commit log, introduced XIVE_ESB_INVALID ] # Signed-off-by: Cédric Le Goater # Signed-off-by: Michael Ellerman # Link: https://lore.kernel.org/r/20200113130118.27969-1-clg@kaod.org # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-gcc --version # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-ld --version # < git log --format=%s --max-count=1 15ae5119c2dd05eb3f4de0c8f10ede7c95e4017b # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_ps3_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- ps3_defconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_ps3_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:204:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/ipc/shm.c: In function 'ksys_shmdt': /kisskb/src/ipc/shm.c:1712:59: warning: 'file' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c: In function 'proc_reg_open': /kisskb/src/include/linux/list.h:65:12: warning: 'pdeo' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c:338:21: note: 'pdeo' was declared here /kisskb/src/net/bluetooth/hidp/core.c: In function 'hidp_connection_add': /kisskb/src/net/bluetooth/hidp/core.c:1386:18: warning: 'session' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/udf/unicode.c: In function 'udf_name_conv_char': /kisskb/src/fs/udf/unicode.c:132:8: warning: 'c' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/cifs/smb2pdu.c: In function 'SMB2_ioctl_init': /kisskb/src/fs/cifs/smb2pdu.c:2811:19: warning: 'in_data_buf' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/splice.c: In function '__do_compat_sys_vmsplice': /kisskb/src/fs/splice.c:1416:8: warning: 'type' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/splice.c: In function '__do_sys_vmsplice': /kisskb/src/fs/splice.c:1390:8: warning: 'type' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/lib/mpi/mpicoder.c: In function 'mpi_read_raw_from_sgl': /kisskb/src/lib/mpi/mpicoder.c:352:8: warning: 'buff' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/net/core/gen_stats.c: In function '__gnet_stats_copy_basic': /kisskb/src/net/core/gen_stats.c:156:19: warning: 'seq' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/lib/rhashtable.c: In function 'rht_deferred_worker': /kisskb/src/include/linux/rhashtable.h:110:10: warning: 'next' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/lib/rhashtable.c:222:28: note: 'next' was declared here /kisskb/src/net/core/dev.c: In function 'validate_xmit_skb_list': /kisskb/src/net/core/dev.c:3547:15: warning: 'tail' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/usb/core/devio.c: In function 'async_completed': /kisskb/src/drivers/usb/core/devio.c:625:23: warning: 'errno' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/net/mac80211/tx.c: In function 'ieee80211_build_hdr': /kisskb/src/net/mac80211/tx.c:2551:27: warning: 'chanctx_conf' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/net/mac80211/mlme.c: In function 'ieee80211_rx_mgmt_beacon': /kisskb/src/net/mac80211/mlme.c:1576:3: warning: 'pwr_level_cisco' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/net/mac80211/mlme.c:1533:6: note: 'pwr_level_cisco' was declared here /kisskb/src/net/wireless/nl80211.c: In function 'nl80211_vendor_cmd_dump': /kisskb/src/net/wireless/nl80211.c:13147:33: warning: 'wdev' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/net/wireless/nl80211.c:13117:21: warning: 'rdev' may be used uninitialized in this function [-Wuninitialized] Completed OK # rm -rf /kisskb/build/powerpc-fixes_ps3_defconfig_powerpc-gcc4.6 # Build took: 0:01:16.663431
