+Subject: dmaengine: at_xdmac: fix to pass correct device identity to free_irq()
+
+From: Wei Yongjun <weiyj.lk@gmail.com>
+
+commit 6a8b0c6b18f62a277ffb2139d0c0253fe35d7feb upstream.
+
+free_irq() expects the same device identity that was passed to
+corresponding request_irq(), otherwise the IRQ is not freed.

+Subject: kernel/fork: fix CLONE_CHILD_CLEARTID regression in nscd
+
+From: Michal Hocko <mhocko@suse.com>
+
+commit 735f2770a770156100f534646158cb58cb8b2939 upstream.
+
+Commit fec1d0115240 ("[PATCH] Disable CLONE_CHILD_CLEARTID for abnormal
+exit") has caused a subtle regression in nscd which uses
+CLONE_CHILD_CLEARTID to clear the nscd_certainly_running flag in the
+shared databases, so that the clients are notified when nscd is
+restarted. Now, when nscd uses a non-persistent database, clients that
+have it mapped keep thinking the database is being updated by nscd, when
+in fact nscd has created a new (anonymous) one (for non-persistent
+databases it uses an unlinked file as backend).
+
+The original proposal for the CLONE_CHILD_CLEARTID change claimed
+(https://lkml.org/lkml/2006/10/25/233):
+
+: The NPTL library uses the CLONE_CHILD_CLEARTID flag on clone() syscalls
+: on behalf of pthread_create() library calls. This feature is used to
+: request that the kernel clear the thread-id in user space (at an address
+: provided in the syscall) when the thread disassociates itself from the
+: address space, which is done in mm_release().
+:
+: Unfortunately, when a multi-threaded process incurs a core dump (such as
+: from a SIGSEGV), the core-dumping thread sends SIGKILL signals to all of
+: the other threads, which then proceed to clear their user-space tids
+: before synchronizing in exit_mm() with the start of core dumping. This
+: misrepresents the state of process's address space at the time of the
+: SIGSEGV and makes it more difficult for someone to debug NPTL and glibc
+: problems (misleading him/her to conclude that the threads had gone away
+: before the fault).
+:
+: The fix below is to simply avoid the CLONE_CHILD_CLEARTID action if a
+: core dump has been initiated.
+
+The resulting patch from Roland (https://lkml.org/lkml/2006/10/26/269)
+seems to have a larger scope than the original patch asked for. It
+seems that limitting the scope of the check to core dumping should work
+for SIGSEGV issue describe above.
+
+[Changelog partly based on Andreas' description]

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Radim Krčmář <rkrcmar@redhat.com>
+
+commit dccbfcf52cebb8963246eba5b177b77f26b34da0 upstream.
+
+If vmcs12 does not intercept APIC_BASE writes, then KVM will handle the
+write with vmcs02 as the current VMCS.
+This will incorrectly apply modifications intended for vmcs01 to vmcs02
+and L2 can use it to gain access to L0's x2APIC registers by disabling
+virtualized x2APIC while using msr bitmap that assumes enabled.
+
+Postpone execution of vmx_set_virtual_x2apic_mode until vmcs01 is the
+current VMCS. An alternative solution would temporarily make vmcs01 the
+current VMCS, but it requires more care.

+Subject: lib/test_hash.c: fix warning in preprocessor symbol evaluation
+
+From: Geert Uytterhoeven <geert@linux-m68k.org>
+
+commit e6173ba42bbdba05fd4f3021c0beda0506271507 upstream.
+
+Some versions of gcc don't like tests for the value of an undefined
+preprocessor symbol, even in the #else branch of an #ifndef:
+
+ lib/test_hash.c:224:7: warning: "HAVE_ARCH__HASH_32" is not defined [-Wundef]
+ #elif HAVE_ARCH__HASH_32 != 1
+ ^
+ lib/test_hash.c:229:7: warning: "HAVE_ARCH_HASH_32" is not defined [-Wundef]
+ #elif HAVE_ARCH_HASH_32 != 1
+ ^
+ lib/test_hash.c:234:7: warning: "HAVE_ARCH_HASH_64" is not defined [-Wundef]
+ #elif HAVE_ARCH_HASH_64 != 1
+ ^
+
+Seen with gcc 4.9, not seen with 4.1.2.
+
+Change the logic to only check the value inside an #ifdef to fix this.

+
+commit 1c8d477a77e2d1d3504419e7f2e02e6422becf9a upstream.
+
+Putting the periodicity timer in the mirror instances is causing
+non-scalable reporting behaviour and missed reporting intervals.
+When you recall layouts and/or implement client side mirroring, it
+leads to consecutive reports with only a few ms between RPC calls.
