This prevents from retrieving an already configured alarm in hardware. This patch fixes the issue by moving the HAS_ALARM bit configuration (if supported by the hardware) above the rtc_device_register() call.

That commit missed the fact that rtc-1307 had its own wakeup irq handling and ended up introducing a kernel splat for at least Beagle x15 boards. Fix that by reverting original commit _and_ passing correct interrupt names on DTS so i2c-core can choose correct IRQ as wakeup. Now that we have automatic wakeirq support, we can revert the original commit which did it manually. Fixes the following warning: [ 10.346582] WARNING: CPU: 1 PID: 263 at linux/drivers/base/power/wakeirq.c:43 dev_pm_attach_wake_irq+0xbc/0xd4() [ 10.359244] rtc-ds1307 2-006f: wake irq already initialized Cc: Tony Lindgren <tony@atomide.com> Cc: Nishanth Menon <nm@ti.com> Signed-off-by: Felipe Balbi <balbi@ti.com> Acked-by: Tony Lindgren <tony@atomide.com> Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Alexandre Belloni <alexandre.belloni@free-electrons.com>

When building a platform without DT support and manually enabling CONFIG_OF, we now get a number of build errors, e.g. arch/arm/kernel/devtree.c: In function 'setup_machine_fdt': arch/arm/kernel/devtree.c:215:19: error: implicit declaration of function 'early_init_dt_verify' [-Werror=implicit-function-declaration] We could now try to separate the use case of booting from DT vs. the case of using the dynamic implementation, but that seems more complicated than it can gain us. This simply changes the ARM Kconfig file to always enable OF_RESERVED_MEM and OF_EARLY_FLATTREE when CONFIG_OF is enabled. These options add a little extra code when we just want the dynamic OF implementation, but that seems like a rather obscure case, and this version solves all CONFIG_OF related randconfig regressions.

Because current code depends on checking se_cmd->se_cmd_flags after return from se_cmd->transport_complete_callback(), this results in first stage having SCF_COMPARE_AND_WRITE_POST set, which incorrectly falls through into second stage CAW processing code, eventually triggering a NULL pointer dereference due to use after free. To address this bug, pass in a new *post_ret parameter into se_cmd->transport_complete_callback(), and depend upon this value instead of ->se_cmd_flags to determine when to return or fall through into ->queue_status() code for CAW.

The case centers around iscsi_target_rx_thread() not invoking allow_signal(SIGINT) before the send_sig(SIGINT, ...) occurs from the failure path, resulting in RX thread hanging indefinately on iscsi_conn->rx_login_comp. Note this bug is a regression introduced by: commit e54198657b65625085834847ab6271087323ffea Author: Nicholas Bellinger <nab@linux-iscsi.org> Date: Wed Jul 22 23:14:19 2015 -0700 iscsi-target: Fix iscsit_start_kthreads failure OOPs To address this bug, complete ->rx_login_complete for good measure in the failure path, and immediately return from RX thread context if connection state did not actually reach full feature phase (TARG_CONN_STATE_LOGGED_IN).
