+CVE-2014-5077 Kernel/SCTP: fix a NULL pointer dereference
+
+A NULL pointer dereference flaw was found in the way the
+Linux kernel's Stream Control Transmission Protocol
+(SCTP) implementation handled simultaneous connections
+between the same hosts. A remote attacker could use this
+flaw to crash the system.

+Subject: powerpc: Fix 64 bit builds with binutils 2.24
+
+Upstream-Status: Backport
+
+With binutils 2.24, various 64 bit builds fail with relocation errors
+such as
+
+arch/powerpc/kernel/built-in.o: In function `exc_debug_crit_book3e':
+        (.text+0x165ee): relocation truncated to fit: R_PPC64_ADDR16_HI
+        against symbol `interrupt_base_book3e' defined in .text section
+        in arch/powerpc/kernel/built-in.o
+arch/powerpc/kernel/built-in.o: In function `exc_debug_crit_book3e':
+        (.text+0x16602): relocation truncated to fit: R_PPC64_ADDR16_HI
+        against symbol `interrupt_end_book3e' defined in .text section
+        in arch/powerpc/kernel/built-in.o
+
+The assembler maintainer says:
+
+ I changed the ABI, something that had to be done but unfortunately
+ happens to break the booke kernel code.  When building up a 64-bit
+ value with lis, ori, shl, oris, ori or similar sequences, you now
+ should use @high and @higha in place of @h and @ha.  @h and @ha
+ (and their associated relocs R_PPC64_ADDR16_HI and R_PPC64_ADDR16_HA)
+ now report overflow if the value is out of 32-bit signed range.
+ ie. @h and @ha assume you're building a 32-bit value. This is needed
+ to report out-of-range -mcmodel=medium toc pointer offsets in @toc@h
+ and @toc@ha expressions, and for consistency I did the same for all
+ other @h and @ha relocs.
+
+Replacing @h with @high in one strategic location fixes the relocation
+errors. This has to be done conditionally since the assembler either
+supports @h or @high but not both.
