2014-03-18x86, vdso: Zero-pad the VVAR pageAndy Lutomirski
By coincidence, the VVAR page is at the end of an ELF segment. As a result, if it ends up being a partial page, the kernel loader will leave garbage behind at the end of the vvar page. Zero-pad it to a full page to fix this issue. This has probably been broken since the VVAR page was introduced. On QEMU, if you dump the run-time contents of the VVAR page, you can find entertaining strings from seabios left behind. It's remotely possible that this is a security bug -- conceivably there's some BIOS out there that leaves something sensitive in the few K of memory that is exposed to userspace.

2014-03-18x86, vdso: Add 32 bit VDSO time support for 64 bit kernelStefani Seibold
This patch add the VDSO time support for the IA32 Emulation Layer. Due the nature of the kernel headers and the LP64 compiler where the size of a long and a pointer differs against a 32 bit compiler, there is some type hacking necessary for optimal performance. The vsyscall_gtod_data struture must be a rearranged to serve 32- and 64-bit code access at the same time: - The seqcount_t was replaced by an unsigned, this makes the vsyscall_gtod_data intedepend of kernel configuration and internal functions. - All kernel internal structures are replaced by fix size elements which works for 32- and 64-bit access - The inner struct clock was removed to pack the whole struct. The "unsigned seq" would be handled by functions derivated from seqcount_t.

2014-03-18ARM: mmp: allow platform devices with modular USBArnd Bergmann
The USB host drivers need platform data to be defined on pxa168 and pxa910, but the conditionals used in the devices.c file only work if the drivers are built-in. This patch fixes the definition by changing the #ifdef to #if IS_ENABLED(), which works both for built-in and modular Kconfig symbols. I found one specific problem using 'randconfig' builds, but for consistency, this patch uses IS_ENABLED() for all Kconfig symbols in these three files.

2014-03-18xen/grant-table: Refactor gnttab_[un]map_refs to avoid m2p_overrideZoltan Kiss
The grant mapping API does m2p_override unnecessarily: only gntdev needs it, for blkback and future netback patches it just cause a lock contention, as those pages never go to userspace. Therefore this series does the following: - the bulk of the original function (everything after the mapping hypercall) is moved to arch-dependent set/clear_foreign_p2m_mapping - the "if (xen_feature(XENFEAT_auto_translated_physmap))" branch goes to ARM - therefore the ARM function could be much smaller, the m2p_override stubs could be also removed - on x86 the set_phys_to_machine calls were moved up to this new funcion from m2p_override functions - and m2p_override functions are only called when there is a kmap_ops param It also removes a stray space from arch/x86/include/asm/xen/page.h.

2014-03-18xen: remove XEN_PRIVILEGED_GUESTMichael Opdenacker
This patch removes the Kconfig symbol XEN_PRIVILEGED_GUEST which is used nowhere in the tree. We do know grub2 has a script that greps kernel configuration files for its macro. It shouldn't do that. As Linus summarized: This is a grub bug. It really is that simple. Treat it as one. Besides, grub2's grepping for that macro is actually superfluous. See, that script currently contains this test (simplified): grep -x CONFIG_XEN_DOM0=y $config || grep -x CONFIG_XEN_PRIVILEGED_GUEST=y $config But since XEN_DOM0 and XEN_PRIVILEGED_GUEST are by definition equal, removing XEN_PRIVILEGED_GUEST cannot influence this test. So there's no reason to not remove this symbol, like we do with all unused Kconfig symbols.

2014-03-17ARM: prima2: build reset code standaloneArnd Bergmann
The prima2 platform code currently depends on the rstc implementation and that in turn depends on the reset controller framework. This removes the platform dependency by letting the driver access arm_pm_restart directly to turn the driver into a standalone entity, and also removes the dependency on the reset controller framework by using "if (IS_ENABLED(CONFIG_RESET_CONTROLLER))". This will cause all code that is used for the reset controller to be dropped by the compiler if the framework is disabled. Signed-off-by: Arnd Bergmann <arnd@arndb.de>

2014-03-17MIPS: mark O32+FP64 experimental for nowPaul Burton
Commit 597ce1723e0f "MIPS: Support for 64-bit FP with O32 binaries" introduced support for setting Status.FR=1 for O32 binaries with the EF_MIPS_FP64 ELF header flag set. Whilst this flag is currently supported by binutils it does introduce an ABI break within userland. Objects built with EF_MIPS_FP64 cannot be safely linked with those built without it since code in either object may assume behaviour specific to a value of FR. More recently there has been discussion around avoiding further fragmentation of the O32 ABI whilst still allowing the use of FR=1 and features such as MSA which depend upon it. Details of the plan to allow this are still being worked on, and whilst the kernel will need the ability to handle FR=1 with O32 tasks it is unclear what else it may need to provide to a userland which seeks to avoid another ABI break. In order to prevent the proliferation of userland which may rely upon the current EF_MIPS_FP64 behaviour this patch marks the kernel support for it experimental & disables it by default. Under current proposals it is likely that this support can simply be enabled again later, but possibly after the introduction of further interfaces with userland and support for the MIPS R5 UFR feature.

2014-03-17s390/smp: limit number of cpus in possible cpu maskHeiko Carstens
Limit the number of bits to the maximum number of cpus a machine can have. possible_cpu_mask typically will have more bits set than a machine may physically have. This results in wasted memory during per-cpu memory allocations, if the possible mask contains more cpus than physically possible for a given configuration.
