2016-11-04rtc: sparc: make sun4v explicitly non-modularPaul Gortmaker1-6/+4
The Kconfig currently controlling compilation of this code is: drivers/rtc/Kconfig:config RTC_DRV_SUN4V drivers/rtc/Kconfig: bool "SUN4V Hypervisor RTC" ...meaning that it currently is not being built as a module by anyone. Lets remove the couple traces of modular infrastructure use, so that when reading the driver there is no doubt it is builtin-only. We delete the MODULE_LICENSE tag etc. since all that information was (or is now) contained at the top of the file in the comments.

The Kconfig currently controlling compilation of this code is: drivers/rtc/Kconfig:config RTC_LIB drivers/rtc/Kconfig: bool ...meaning that it currently is not being built as a module by anyone. Lets remove the couple traces of modular infrastructure use, so that when reading the driver there is no doubt it is builtin-only. We delete the MODULE_LICENSE tag since all that information is already contained at the top of the file in the comments. We don't replace module.h with init.h since the file doesn't need that.

2016-10-19rtc: cmos: Reject unsupported alarm valuesGabriele Mazzotta1-0/+72
Some platforms allows to specify the month and day of the month in which an alarm should go off, some others the day of the month and some others just the time. Currently any given value is accepted by the driver and only the supported fields are used to program the hardware. As consequence, alarms are potentially programmed to go off in the wrong moment. Fix this by rejecting any unsupported value. Signed-off-by: Gabriele Mazzotta <gabriele.mzt@gmail.com> Signed-off-by: Alexandre Belloni <alexandre.belloni@free-electrons.com>

2016-10-14fs/super.c: fix race between freeze_super() and thaw_super()Oleg Nesterov1-3/+3
Change thaw_super() to check frozen != SB_FREEZE_COMPLETE rather than frozen == SB_UNFROZEN, otherwise it can race with freeze_super() which drops sb->s_umount after SB_FREEZE_WRITE to preserve the lock ordering. In this case thaw_super() will wrongly call s_op->unfreeze_fs() before it was actually frozen, and call sb_freeze_unlock() which leads to the unbalanced percpu_up_write(). Unfortunately lockdep can't detect this, so this triggers misc BUG_ON()'s in kernel/rcu/sync.c.

2016-10-14iov_iter: kernel-doc import_iovec() and rw_copy_check_uvector()Vegard Nossum2-0/+51
Both import_iovec() and rw_copy_check_uvector() take an array (typically small and on-stack) which is used to hold an iovec array copy from userspace. This is to avoid an expensive memory allocation in the fast path (i.e. few iovec elements). The caller may have to check whether these functions actually used the provided buffer or allocated a new one -- but this differs between the too.

git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma Pull more rdma updates from Doug Ledford: "This merge window was the first where Huawei had to try and coordinate their patches between their net driver and their new roce driver (similar to mlx4 and mlx5). They didn't do horribly, but there were some issues (and we knew that because they simply didn't know what to do in the beginning). As a result, I had a set of patches that depended on some patches that normally would have come to you via Dave's tree. Those patches have been on netdev@ for a while, so I got Dave to give me his approval to send them to you. As such, the other 29 patches I had behind them are also now ready to go. This catches the hns and hns-roce drivers up to current, and for future patches we are working with them to get them up to speed on how to do joint driver development so that they don't have these sorts of cross tree dependency issues again. BTW, Dave gave me permission to add his Acked-by: to the patches against the net tree, but I've had this branch through 0day (but not linux-next since it was off by itself) and I didn't want to rebase the series just to add Dave's ack for the 8 patches in the net area.

2016-10-14CIFS: Retrieve uid and gid from special sid if enabledSteve French1-0/+123
New mount option "idsfromsid" indicates to cifs.ko that it should try to retrieve the uid and gid owner fields from special sids. This patch adds the code to parse the owner sids in the ACL to see if they match, and if so populate the uid and/or gid from them. This is faster than upcalling for them and asking winbind, and is a fairly common case, and is also helpful when cifs.upcall and idmapping is not configured.
