As part of this make the usual change to xen_ulong_t in place of unsigned long. This change has no impact on x86. The Linux definition of struct multicall_entry.result differs from the Xen definition, I think for good reasons, and used a long rather than an unsigned long. Therefore introduce a xen_long_t, which is a long on x86 architectures and a signed 64-bit integer on ARM. Use uint32_t nr_calls on x86 for consistency with the ARM definition. Build tested on amd64 and i386 builds. Runtime tested on ARM.

fixup_user_fault() is used by the futex code when the direct user access fails, and the futex code wants it to either map in the page in a usable form or return an error. It relied on handle_mm_fault() to map the page, and correctly checked the error return from that, but while that does map the page, it doesn't actually guarantee that the page will be mapped with sufficient permissions to be then accessed. So do the appropriate tests of the vma access rights by hand. [ Side note: arguably handle_mm_fault() could just do that itself, but we have traditionally done it in the caller, because some callers - notably get_user_pages() - have been able to access pages even when they are mapped with PROT_NONE. Maybe we should re-visit that design decision, but in the meantime this is the minimal patch. ] Found by Dave Jones running his trinity tool.

Inferring the mount hierarchy correctly from /proc/mounts is hard when MS_MOVE may have been used, and the previous code did it wrongly. This change simplifies the logic to only require that /dev/shm be _on_ tmpfs (which can be checked trivially with statfs) rather than that it be a _mountpoint_ of tmpfs, since there isn't a compelling reason to be that strict. We also now check for tmpfs on whatever directory we ultimately use so that the user is better informed. This change also moves the more standard TMPDIR environment variable check ahead of the others. Applies to 3.12.

On some newer laptops with a trackpoint the physical buttons for the trackpoint have been removed to allow for a larger touchpad. On these laptops the buttonpad has clearly marked areas on the top which are to be used as trackpad buttons. Users of the event device-node need to know about this, so that they can properly interpret BTN_LEFT events as being a left / right / middle click depending on where on the button pad the clicking finger is. This commits adds a INPUT_PROP_TOPBUTTONPAD device property which drivers for such buttonpads will use to signal to the user that this buttonpad not only has the normal bottom button area, but also a top button area.

serio devices exposed via platform firmware interfaces such as ACPI may provide additional identifying information of use to userspace. We don't associate the serio devices with the firmware device (we don't set it as parent), so there's no way for userspace to make use of this information. We cannot change the parent for serio devices instantiated though a firmware interface as that would break suspend / resume ordering. Therefore this patch adds a new firmware_id sysfs attribute so that userspace can get a string from there with any additional identifying information the firmware interface may provide.

In the current version, when using perf record, if something goes wrong in tools/perf/builtin-record.c:375 session = perf_session__new(file, false, NULL); The error message: "Not enough memory for reading per file header" is issued. This error message seems to be outdated and is not very helpful. This patch proposes to replace this error message by "Perf session creation failed" I believe this issue has been brought to lkml: https://lkml.org/lkml/2014/2/24/458 although this patch only tackles a (small) part of the issue. Additionnaly, this patch improves error reporting in tools/perf/util/data.c open_file_write. Currently, if the call to open fails, the user is unaware of it.
