2016-01-12x86/mm: Use PAGE_ALIGNED instead of IS_ALIGNEDKefeng Wang

2016-01-12selftests/x86: Disable the ldt_gdt_64 test for nowAndy Lutomirski
ldt_gdt.c relies on cross-cpu invalidation of SS to do one of its tests. On 32-bit builds, this works fine, but on 64-bit builds, it only works if the kernel has proper SS sigcontext handling for 64-bit user programs. Since the SS fixes are currently reverted, restrict the test case to 32 bits for now. In principle, I could change the test to use a different segment register, but it would be messy: CS can't point to the LDT for 64-bit code, and the other registers don't result in immediate faults because they aren't reloaded on kernel -> user transitions. When we fix sigcontext (in 4.6?), we can revert this.

2016-01-12x86/mm/pat: Make split_page_count() check for empty levels to fix ↵Dave Jones
/proc/meminfo output In CONFIG_PAGEALLOC_DEBUG=y builds, we disable 2M pages. Unfortunatly when we split up mappings during boot, split_page_count() doesn't take this into account, and starts decrementing an empty direct_pages_count[] level. This results in /proc/meminfo showing crazy things like: DirectMap2M: 18446744073709543424 kB Signed-off-by: Dave Jones <davej@codemonkey.org.uk> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: Andy Lutomirski <luto@amacapital.net> Cc: Borislav Petkov <bp@alien8.de> Cc: Brian Gerst <brgerst@gmail.com> Cc: Denys Vlasenko <dvlasenk@redhat.com> Cc: H.

2016-01-11Input: elantech - mark protocols v2 and v3 as semi-mtBenjamin Tissoires
When using a protocol v2 or v3 hardware, elantech uses the function elantech_report_semi_mt_data() to report data. This devices are rather creepy because if num_finger is 3, (x2,y2) is (0,0). Yes, only one valid touch is reported. Anyway, userspace (libinput) is now confused by these (0,0) touches, and detect them as palm, and rejects them. Commit 3c0213d17a09 ("Input: elantech - fix semi-mt protocol for v3 HW") was sufficient enough for xf86-input-synaptics and libinput before it has palm rejection. Now we need to actually tell libinput that this device is a semi-mt one and it should not rely on the actual values of the 2 touches.
