[PATCH] usb: dwc3: gadget: Init only available HW eps

by Thinh Nguyen

Typically FPGA devices are configured with CoreConsultant parameter DWC_USB3x_EN_LOG_PHYS_EP_SUPT=0 to reduce gate count and improve timing. This means that the number of INs equals to OUTs endpoints. But typically non-FPGA devices enable this CoreConsultant parameter to support flexible endpoint mapping and potentially may have unequal number of INs to OUTs physical endpoints. The driver must check how many physical endpoints are available for each direction and initialize them properly.

[PATCH 00/16] rcu/nocb updates

by Frederic Weisbecker

So this set has grown further than I expected. This addresses most reviews from Paul and also consolidates the nocb timers code. Please mind the very first patch that is a stable bugfix. git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks.git rcu/dev HEAD: 75991420c246c26f598602da1a70947b5bdf77b6 Thanks, Frederic --- Frederic Weisbecker (16): rcu/nocb: Fix potential missed nocb_timer rearm rcu/nocb: Comment the reason behind BH disablement on batch processing rcu/nocb: Forbid NOCB toggling on offline CPUs rcu/nocb: Only (re-)initialize segcblist when needed on CPU up rcu/nocb: Disable bypass when CPU isn't completely offloaded rcu/nocb: Avoid confusing double write of rdp->nocb_cb_sleep rcu/nocb: Rename nocb_gp_update_state to nocb_gp_update_state_deoffloading rcu/nocb: Move trace_rcu_nocb_wake() calls outside nocb_lock when possible rcu/nocb: Merge nocb_timer to the rdp leader rcu/nocb: Directly call __wake_nocb_gp() from bypass timer rcu/nocb: Allow de-offloading rdp leader rcu/nocb: Cancel nocb_timer upon nocb_gp wakeup rcu/nocb: Delete bypass_timer upon nocb_gp wakeup rcu/nocb: Only cancel nocb timer if not polling rcu/nocb: Prepare for finegrained deferred wakeup rcu/nocb: Unify timers include/linux/rcu_segcblist.h | 7 +- include/trace/events/rcu.h | 1 + kernel/rcu/tree.c | 12 +- kernel/rcu/tree.h | 9 +- kernel/rcu/tree_plugin.h | 280 ++++++++++++++++++++++-------------------- 5 files changed, 163 insertions(+), 146 deletions(-)

[PATCH v5 3/3] KEYS: trusted: Reserve TPM for seal and unseal operations

by jarkko＠kernel.org

From: Jarkko Sakkinen <jarkko(a)kernel.org> When TPM 2.0 trusted keys code was moved to the trusted keys subsystem, the operations were unwrapped from tpm_try_get_ops() and tpm_put_ops(), which are used to take temporarily the ownership of the TPM chip. The ownership is only taken inside tpm_send(), but this is not sufficient, as in the key load TPM2_CC_LOAD, TPM2_CC_UNSEAL and TPM2_FLUSH_CONTEXT need to be done as a one single atom. Take the TPM chip ownership before sending anything with tpm_try_get_ops() and tpm_put_ops(), and use tpm_transmit_cmd() to send TPM commands instead of tpm_send(), reverting back to the old behaviour.
