2020-07-15drm/amdgpu: RAS emergency restart logic refineWenhui Sheng
If we are in RAS triggered situation and BACO isn't support, emergency restart is needed, and this code is only needed for some specific cases(vega20 with given smu fw version). After we add smu mode1 reset for sienna cichlid, we need to share AMD_RESET_METHOD_MODE1 with psp mode1 reset, so in amdgpu_device_gpu_recover, we need differentiate which mode1 reset we are using, then decide if it's a full reset and then decide if emergency restart is needed, the logic will become much more complex. After discussion with Hawking, move emergency restart logic to an independent function.

2020-07-15selftests/powerpc: Use proper error code to check fault addressHaren Myneni
ERR_NX_TRANSLATION(CSB.CC=5) is for internal to VAS for fault handling and should not used by OS. ERR_NX_AT_FAULT(CSB.CC=250) is the proper error code should be reported by OS when NX encounters address translation failure. This patch uses CC=250 to determine the fault address when the request is not successful.

2020-07-15powerpc/vas: Report proper error code for address translation failureHaren Myneni
P9 DD2 NX workbook (Table 4-36) says DMA controller uses CC=5 internally for translation fault handling. NX reserves CC=250 for OS to notify user space when NX encounters address translation failure on the request buffer. Not an issue in earlier releases as NX does not get faults on kernel addresses. This patch defines CSB_CC_FAULT_ADDRESS(250) and updates CSB.CC with this proper error code for user space.

2020-07-15fuse: Fix parameter for FS_IOC_{GET,SET}FLAGSChirantan Ekbote
The ioctl encoding for this parameter is a long but the documentation says it should be an int and the kernel drivers expect it to be an int. If the fuse driver treats this as a long it might end up scribbling over the stack of a userspace process that only allocated enough space for an int. This was previously discussed in [1] and a patch for fuse was proposed in [2]. From what I can tell the patch in [2] was nacked in favor of adding new, "fixed" ioctls and using those from userspace. However there is still no "fixed" version of these ioctls and the fact is that it's sometimes infeasible to change all userspace to use the new one. Handling the ioctls specially in the fuse driver seems like the most pragmatic way for fuse servers to support them without causing crashes in userspace applications that call them.

2020-07-15Revert "thermal: mediatek: fix register index error"Enric Balletbo i Serra
This reverts commit eb9aecd90d1a39601e91cd08b90d5fee51d321a6 The above patch is supposed to fix a register index error on mt2701. It is not clear if the problem solved is a hang or just an invalid value returned, my guess is the second. The patch introduces, though, a new hang on MT8173 device making them unusable. So, seems reasonable, revert the patch because introduces a worst issue. The reason I send a revert instead of trying to fix the issue for MT8173 is because the information needed to fix the issue is in the datasheet and is not public. So I am not really able to fix it. Fixes the following bug when CONFIG_MTK_THERMAL is set on MT8173 devices.
