The count of errors is picked up from bits 52:38 of the machine check bank status register. But this is the count of *corrected* errors. If an uncorrected error is being logged, the h/w sets this field to 0. Which means that when edac_mc_handle_error() is called, the EDAC core will carefully add zero to the appropriate uncorrected error counts.

The altera edac driver passes a token from a DT resource as resource_size_t into an SMC call, but casts it to an __iomem pointer and then a plain void pointer inbetween, mixing three or four incompatible types in the process. The compiler complains about one of the conversions: drivers/edac/altera_edac.c: In function 'altr_init_a10_ecc_block': drivers/edac/altera_edac.c:1053:10: error: cast to pointer from integer of \ different size [-Werror=int-to-pointer-cast] base = (void __iomem *)res.start; ^ drivers/edac/altera_edac.c: In function 'altr_edac_a10_probe': drivers/edac/altera_edac.c:2062:10: error: cast to pointer from integer of \ different size [-Werror=int-to-pointer-cast] base = (void __iomem *)res.start; Using a static checker probably also notices the __iomem cast. Solving this properly isn't trivial, but simply casting to a 'uintptr_t' instead of 'void __iomem *' makes it less wrong and should avoid the warnings.

Change Stratix10 regmap to use offsets from a base to match the Arria10 regmap and allow re-use of the Arria10 functions.

On Stratix10, the ECC offsets are similar to the existing Arria10 functions and this can be leveraged to simplify the EDAC driver as follows: 1. Fold Stratix10 specifics into Arria10 structures and functions. 2. Implement the Stratix10 System Manager register accesses using a custom regmap to allow use with the Arria10 System Manager regmaps. 3. Stratix10 double bit errors are implemented as SError instead of interrupts so use a panic notifier.

Trond Myklebust authored
The previous fix broke recovery of delegated stateids because it assumes that if we did not mark the delegation as suspect, then the delegation has effectively been revoked, and so it removes that delegation irrespectively of whether or not it is valid and still in use. While this is "mostly harmless" for ordinary I/O, we've seen pNFS fail with LAYOUTGET spinning in an infinite loop while complaining that we're using an invalid stateid (in this case the all-zero stateid). What we rather want to do here is ensure that the delegation is always correctly marked as needing testing when that is the case. So we want to close the loophole offered by nfs4_schedule_stateid_recovery(), which marks the state as needing to be reclaimed, but not the delegation that may be backing it.

Pull staging/IIO driver fixes from Greg KH: "Here are a few small staging and iio driver fixes for -rc4. Nothing major, just a few small bugfixes for some reported issues, and a MAINTAINERS file update for the fbtft drivers. We also re-enable the building of the erofs filesystem as the XArray patches that were causing it to break never got merged in the -rc1 cycle, so there's no reason it can't be turned back on for now. The problem that was previously there is now being handled in the Xarray tree at the moment, so it will not hit us again in the future. All of these patches have been in linux-next with no reported issues" * tag 'staging-4.19-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: staging: vboxvideo: Change address of scanout buffer on page-flip staging: vboxvideo: Fix IRQs no longer working staging: gasket: TODO: re-implement using UIO staging/fbtft: Update TODO and mailing lists staging: erofs: rename superblock flags (MS_xyz -> SB_xyz) iio: imu: st_lsm6dsx: take into account ts samples in wm configuration Revert "iio: temperature: maxim_thermocouple: add MAX31856 part" Revert "staging: erofs: disable compiling temporarile" MAINTAINERS: Switch a maintainer for drivers/staging/gasket staging: wilc1000: revert "fix TODO to compile spi and sdio components in single module"
