2018-01-25x86/hyperv: Stop suppressing X86_FEATURE_PCIDVitaly Kuznetsov
When hypercall-based TLB flush was enabled for Hyper-V guests PCID feature was deliberately suppressed as a precaution: back then PCID was never exposed to Hyper-V guests and it wasn't clear what will happen if some day it becomes available. The day came and PCID/INVPCID features are already exposed on certain Hyper-V hosts. From TLFS (as of 5.0b) it is unclear how TLB flush hypercalls combine with PCID. In particular the usage of PCID is per-cpu based: the same mm gets different CR3 values on different CPUs. If the hypercall does exact matching this will fail. However, this is not the case. David Zhang explains: "In practice, the AddressSpace argument is ignored on any VM that supports PCIDs. Architecturally, the AddressSpace argument must match the CR3 with PCID bits stripped out (i.e., the low 12 bits of AddressSpace should be 0 in long mode). The flush hypercalls flush all PCIDs for the specified AddressSpace." With this, PCID can be enabled.

2018-01-25mtd: nand: sunxi: Fix ECC strength choiceMiquel Raynal
When the requested ECC strength does not exactly match the strengths supported by the ECC engine, the driver is selecting the closest strength meeting the 'selected_strength > requested_strength' constraint. Fix the fact that, in this particular case, ecc->strength value was not updated to match the 'selected_strength'. For instance, one can encounter this issue when no ECC requirement is filled in the device tree while the NAND chip minimum requirement is not a strength/step_size combo natively supported by the ECC engine.

2018-01-25mtd: nand: gpmi: Fix subpage readsBoris Brezillon
Commit 25f815f66a14 ("mtd: nand: force drivers to explicitly send READ/PROG commands") added a call to nand_read_page_op() in gpmi_ecc_read_page(), which means this function now sends a READ0 command and place the data pointer at the beginning of the page. This logic is breaking gpmi_ecc_read_subpage() which was calling gpmi_ecc_read_page() and expected it to only retrieve the data without sending the READ0 command. Create a gpmi_ecc_read_page_data() helper which only does the data retrieval and ECC correction steps and implement gpmi_ecc_read_page() as a wrapper that calls nand_read_page_op()+gpmi_ecc_read_page_data(). This way, gpmi_ecc_read_subpage() can call gpmi_ecc_read_page_data() which restores the logic we had before commit 25f815f66a14 ("mtd: nand: force drivers to explicitly send READ/PROG commands").

2018-01-25wil6210: fix random failure to bring network interface upLior David
Currently when we want to bring the interface up, we first reset the device which causes the boot loader to run. Then we halt the device CPU, load FW image and resume the device CPU. There are some boot loader versions which perform redundant memory accesses even when idle. Halting the device CPU while boot loader access memory can cause the device memory controller to get stuck, the FW will fail to load and the network interface will not come up. For such boot loaders implement a workaround where we freeze the boot loader before halting the device CPU, so it will not perform any memory accesses.

2018-01-24cifs: Fix autonegotiate security settings mismatchDaniel N Pettersson
Autonegotiation gives a security settings mismatch error if the SMB server selects an SMBv3 dialect that isn't SMB3.02. The exact error is "protocol revalidation - security settings mismatch". This can be tested using Samba v4.2 or by setting the global Samba setting max protocol = SMB3_00. The check that fails in smb3_validate_negotiate is the dialect verification of the negotiate info response. This is because it tries to verify against the protocol_id in the global smbdefault_values. The protocol_id in smbdefault_values is SMB3.02. In SMB2_negotiate the protocol_id in smbdefault_values isn't updated, it is global so it probably shouldn't be, but server->dialect is. This patch changes the check in smb3_validate_negotiate to use server->dialect instead of server->vals->protocol_id. The patch works with autonegotiate and when using a specific version in the vers mount option.

2018-01-24cifs: Fix missing put_xid in cifs_file_strict_mmapMatthew Wilcox
If cifs_zap_mapping() returned an error, we would return without putting the xid that we got earlier. Restructure cifs_file_strict_mmap() and cifs_file_mmap() to be more similar to each other and have a single point of return that always puts the xid.
