To calculate the pressure on a restrictive touchscreen we need to know resistance at least of X plate. Some calculations need to use both X and Y values. So let's add generic properties which can be used by all drivers. Signed-off-by:

This reverts commit 0c85a7e8. The games with 'rm' are on (two separate instances) of a local variable, and make no difference. Quoting Aditya Pakki: "I was the author of the patch and it was the cause of the giant UMN revert. The patch is garbage and I was unaware of the steps involved in retracting it. I *believed* the maintainers would pull it, given it was already under Greg's list. The patch does not introduce any bugs but is pointless and is stupid. I accept my incompetence and for not requesting a revert earlier." Link: https://lwn.net/Articles/854319/ Requested-by:

No problem on 64-bit, or without huge pages, but xfstests generic/285 and other SEEK_HOLE/SEEK_DATA tests have regressed on huge tmpfs, and on 32-bit architectures, with the new mapping_seek_hole_data(). Several different bugs turned out to need fixing. u64 cast to stop losing bits when converting unsigned long to loff_t (and let's use shifts throughout, rather than mixed with * and /). Use round_up() when advancing pos, to stop assuming that pos was already THP-aligned when advancing it by THP-size. (This use of round_up() assumes that any THP has THP-aligned index: true at present and true going forward, but could be recoded to avoid the assumption.) Use xas_set() when iterating away from a THP, so that xa_index stays in synch with start, instead of drifting away to return bogus offset. Check start against end to avoid wrapping 32-bit xa_index to 0 (and to handle these additional cases, seek_data or not, it's easier to break the loop than goto: so rearrange exit from the function).

No problem on 64-bit, or without huge pages, but xfstests generic/308 hung uninterruptibly on 32-bit huge tmpfs. Since commit 0cc3b0ec ("Clarify (and fix) in 4.13 MAX_LFS_FILESIZE macros"), MAX_LFS_FILESIZE is only a PAGE_SIZE away from wrapping 32-bit xa_index to 0, so the new find_lock_entries() has to be extra careful when handling a THP.

The only stepping of Broadwell Xeon parts is stepping 1. Fix the relevant isolation_ucodes[] entry, which previously enumerated stepping 2. Although the original commit was characterized as an optimization, it is also a workaround for a correctness issue. If a PMI arrives between kvm's call to perf_guest_get_msrs() and the subsequent VM-entry, a stale value for the IA32_PEBS_ENABLE MSR may be restored at the next VM-exit. This is because, unbeknownst to kvm, PMI throttling may clear bits in the IA32_PEBS_ENABLE MSR. CPUs with "PEBS isolation" don't suffer from this issue, because perf_guest_get_msrs() doesn't report the IA32_PEBS_ENABLE value.

Commit 941432d0 ("arm64: dts: allwinner: Drop non-removable from SoPine/LTS SD card") enabled the card detect GPIO for the SOPine module, along the way with the Pine64-LTS, which share the same base .dtsi. This was based on the observation that the Pine64-LTS has as "push-push" SD card socket, and that the schematic mentions the card detect GPIO. After having received two reports about failing SD card access with that patch, some more research and polls on that subject revealed that there are at least two different versions of the Pine64-LTS out there: - On some boards (including mine) the card detect pin is "stuck" at high, regardless of an microSD card being inserted or not. - On other boards the card-detect is working, but is active-high, by virtue of an explicit inverter circuit, as shown in the schematic. To cover all versions of the board out there, and don't take any chances, let's revert the introduction of the active-low CD GPIO, but let's use the broken-cd property for the Pine64-LTS this time. That should avoid regressions and should work for everyone, even allowing SD card changes now. The SOPine card detect has proven to be working, so let's keep that GPIO in place.
