2023-12-04arm64: dts: rockchip: Fix PCI node addresses on rk3399-gruRob Herring
The rk3399-gru PCI node addresses are wrong. In rk3399-gru-scarlet, the bus number in the address should be 0. This is because bus number assignment is dynamic and not known up front. For FDT, the bus number is simply ignored. In rk3399-gru-chromebook, the addresses are simply invalid. The first "reg" entry must be the configuration space for the device. The entry should be all 0s except for device/slot and function numbers. The existing 64-bit memory space (0x83000000) entries are not valid because they must have the BAR address in the lower byte of the first cell. Warnings for these are enabled by adding the missing 'device_type = "pci"' for the root port node.

2023-12-04cifs: Fix flushing, invalidation and file size with FICLONEDavid Howells
Fix a number of issues in the cifs filesystem implementation of the FICLONE ioctl in cifs_remap_file_range(). This is analogous to the previously fixed bug in cifs_file_copychunk_range() and can share the helper functions. Firstly, the invalidation of the destination range is handled incorrectly: We shouldn't just invalidate the whole file as dirty data in the file may get lost and we can't just call truncate_inode_pages_range() to invalidate the destination range as that will erase parts of a partial folio at each end whilst invalidating and discarding all the folios in the middle. We need to force all the folios covering the range to be reloaded, but we mustn't lose dirty data in them that's not in the destination range. Further, we shouldn't simply round out the range to PAGE_SIZE at each end as cifs should move to support multipage folios. Secondly, there's an issue whereby a write may have extended the file locally, but not have been written back yet. This can leaves the local idea of the EOF at a later point than the server's EOF. If a clone request is issued, this will fail on the server with STATUS_INVALID_VIEW_SIZE (which gets translated to -EIO locally) if the clone source extends past the server's EOF. Fix this by: (0) Flush the source region (already done). The flush does nothing and the EOF isn't moved if the source region has no dirty data. (1) Move the EOF to the end of the source region if it isn't already at least at this point. If we can't do this, for instance if the server doesn't support it, just flush the entire source file. (2) Find the folio (if present) at each end of the range, flushing it and increasing the region-to-be-invalidated to cover those in their entirety. (3) Fully discard all the folios covering the range as we want them to be reloaded. (4) Then perform the extent duplication. Thirdly, set i_size after doing the duplicate_extents operation as this value may be used by various things internally. stat() hides the issue because setting ->time to 0 causes cifs_getatr() to revalidate the attributes. These were causing the cifs/001 xfstest to fail.

When typec_altmode_put_partner is called by a plug altmode upon release, the port altmode the plug belongs to will not remove its reference to the plug. The check to see if the altmode being released evaluates against the released altmode's partner instead of the calling altmode itself, so change adev in typec_altmode_put_partner to properly refer to the altmode being released. typec_altmode_set_partner is not run for port altmodes, so also add a check in typec_altmode_release to prevent typec_altmode_put_partner() calls on port altmode release.

2023-12-04mlxbf-bootctl: correctly identify secure boot with development keysDavid Thompson
The secure boot state of the BlueField SoC is represented by two bits: 0 = production state 1 = secure boot enabled 2 = non-secure (secure boot disabled) 3 = RMA state There is also a single bit to indicate whether production keys or development keys are being used when secure boot is enabled. This single bit (specified by MLXBF_BOOTCTL_SB_DEV_MASK) only has meaning if secure boot state equals 1 (secure boot enabled). The secure boot states are as follows: - “GA secured” is when secure boot is enabled with official production keys. - “Secured (development)” is when secure boot is enabled with development keys. Without this fix “GA Secured” is displayed on development cards which is misleading. This patch updates the logic in "lifecycle_state_show()" to handle the case where the SoC is configured for secure boot and is using development keys.

indexing mode The multiplier is already promoted to unsigned long, however the frequency calculations done when using level indexing mode doesn't use the multiplier computed. It instead hardcodes the multiplier value of 1000 at all the usage sites. Clean that up by assigning the multiplier value of 1000 when using the perf level indexing mode and update the frequency calculations to use the multiplier instead. It should fix the possible frequency truncation for all the values greater than or equal to 4GHz on 64-bit machines.
