2014-12-08ASoC: samsung: Fix non-DT use of I2S controllerMark Brown
The changes in commit a5a56871f804e (ASoC: samsung: add support for exynos7 I2S controller) introduce a new variant_regs structure in the driver data which is now mandatory for accessing registers. Unfortunately this is only hooked up for DT platforms so non-DT platforms like my primary development platform for audio are broken by this change and crash on boot. Since the only non-DT user of these device is s3c64xx fix this by making the standard samsung-i2s device be of type I2Sv3 and add a new I2Sv4 name to the platform data section, currently using the I2Sv5 information which should be about right.

2014-12-08x86/kconfig/defconfig: Enable CONFIG_FHANDLE=yRichard Weinberger
systemd has a hard dependency on CONFIG_FHANDLE. If you run systemd with CONFIG_FHANDLE=n it will somehow boot but fail to spawn a getty or other basic services. As systemd is now used by most x86 distributions it makes sense to enabled this by default and save kernel hackers a lot of value debugging time.

2014-12-08xen: introduce helper functions to do safe read and write accessesJuergen Gross
Introduce two helper functions to safely read and write unsigned long values from or to memory when the access may fault because the mapping is non-present or read-only. These helpers can be used instead of open coded uses of __get_user() and __put_user() avoiding the need to do casts to fix sparse warnings. Use the helpers in page.h and p2m.c. This will fix the sparse warnings when doing "make C=1". Signed-off-by: Juergen Gross <jgross@suse.com> Signed-off-by: David Vrabel <david.vrabel@citrix.com>

2014-12-08x86/ticketlock: Fix spin_unlock_wait() livelockOleg Nesterov
arch_spin_unlock_wait() looks very suboptimal, to the point I think this is just wrong and can lead to livelock: if the lock is heavily contended we can never see head == tail. But we do not need to wait for arch_spin_is_locked() == F. If it is locked we only need to wait until the current owner drops this lock. So we could simply spin until old_head != lock->tickets.head in this case, but .head can overflow and thus we can't check "unlocked" only once before the main loop. Also, the "unlocked" check can ignore TICKET_SLOWPATH_FLAG bit.

2014-12-08s390/debug: avoid function call for debug_sprintf_*Christian Borntraeger
debug_sprintf_event/exception are called even for debug events with a disabling debug level. All other functions already do the check in a wrapper function. Lets do the same here. Due to the var_args the compiler rejects to make this function inline. So let's wrap this via a macro. This patch saves around 80 ns on my z196 for a KVM round trip (we have two debug statements for entry and exit) when KVM is build as a module. The savings for built-in drivers is smaller as we then avoid the PLT overhead for a function call.

This patch will also introduce another change in behavior, since before the response pattern to the tuning command wasn't verified by sdhci-esdhc-imx. The mmc_send_tuning() does that.

From the wiretrace we can see that the server returns different UIDs as response to NTLMSSP_NEGOTIATE and NTLMSSP_AUTH phases. With changes in the authentication code, we no longer set the cifs_sess->Suid returned in response to the NTLM_AUTH phase and continue to use the UID sent in response to the NTLMSSP_NEGOTIATE phase.
