The SME encryption mask is for masking 64-bit pagetable entries. It being an unsigned long works fine on X86_64 but on 32-bit builds in truncates bits leading to Xen guests crashing very early. And regardless, the whole SME mask handling shouldnt've leaked into 32-bit because SME is X86_64-only feature. So, first make the mask u64. And then, add trivial 32-bit versions of the __sme_* macros so that nothing happens there.

When Linux brings a CPU down and back up, it switches to init_mm and then loads swapper_pg_dir into CR3. With PCID enabled, this has the side effect of masking off the ASID bits in CR3. This can result in some confusion in the TLB handling code. If we bring a CPU down and back up with any ASID other than 0, we end up with the wrong ASID active on the CPU after resume. This could cause our internal state to become corrupt, although major corruption is unlikely because init_mm doesn't have any user pages. More obviously, if CONFIG_DEBUG_VM=y, we'll trip over an assertion in the next context switch. The result of *that* is a failure to resume from suspend with probability 1 - 1/6^(cpus-1). Fix it by reinitializing cpu_tlbstate on resume and CPU bringup.

Pull GFS2 updates from Bob Peterson: "We've got a whopping 29 GFS2 patches for this merge window, mainly because we held some back from the previous merge window until we could get them perfected and well tested. We have a couple patch sets, including my patch set for protecting glock gl_object and Andreas Gruenbacher's patch set to fix the long-standing shrink- slab hang, plus a bunch of assorted bugs and cleanups. Summary: - I fixed a bug whereby an IO error would lead to a double-brelse. - Andreas Gruenbacher made a minor cleanup to call his relatively new function, gfs2_holder_initialized, rather than doing it manually. This was just missed by a previous patch set. - Jan Kara fixed a bug whereby the SGID was being cleared when inheriting ACLs. - Andreas found a bug and fixed it in his previous patch, "Get rid of flush_delayed_work in gfs2_evict_inode". A call to flush_delayed_work was deleted from *gfs2_inode_lookup and added to gfs2_create_inode. - Wang Xibo found and fixed a list_add call in inode_go_lock that specified the parameters in the wrong order. - Coly Li submitted a patch to add the REQ_PRIO to some of GFS2's metadata reads that were accidentally missing them. - I submitted a 4-patch set to protect the glock gl_object field. GFS2 was setting and checking gl_object with no locking mechanism, so the value was occasionally stomped on, which caused file system corruption. - I submitted a small cleanup to function gfs2_clear_rgrpd. It was needlessly adding rgrp glocks to the lru list, then pulling them back off immediately. The rgrp glocks don't use the lru list anyway, so doing so was just a waste of time. - I submitted a patch that checks the GLOF_LRU flag on a glock before trying to remove it from the lru_list. This avoids a lot of unnecessary spin_lock contention. - I submitted a patch to delete GFS2's debugfs files only after we evict all the glocks. Before this patch, GFS2 would delete the debugfs files, and if unmount hung waiting for a glock, there was no way to debug the problem. Now, if a hang occurs during umount, we can examine the debugfs files to figure out why it's hung. - Andreas Gruenbacher submitted a patch to fix some trivial typos. - Andreas also submitted a five-part patch set to fix the longstanding hang involving the slab shrinker: dlm requires memory, calls the inode shrinker, which calls gfs2's evict, which calls back into DLM before it can evict an inode. - Abhi Das submitted a patch to forcibly flush the active items list to relieve memory pressure. This fixes a long-standing bug whereby GFS2 was getting hung permanently in balance_dirty_pages. - Thomas Tai submitted a patch to fix a slab corruption problem due to a residual pointer left in the lock_dlm lockstruct. - I submitted a patch to withdraw the file system if IO errors are encountered while writing to the journals or statfs system file which were previously not being sent back up. Before, some IO errors were sometimes not be detected for several hours, and at recovery time, the journal errors made journal replay impossible. - Andreas has a patch to fix an annoying format-truncation compiler warning so GFS2 compiles cleanly. - I have a patch that fixes a handful of sparse compiler warnings. - Andreas fixed up an useless gl_object warning caused by an earlier patch. - Arvind Yadav added a patch to properly constify our rhashtable params declare. - I added a patch to fix a regression caused by the non-recursive delete and truncate patch that caused file system blocks to not be properly freed. - Ernesto A. Fernández added a patch to fix a place where GFS2 would send back the wrong return code setting extended attributes. - Ernesto also added a patch to fix a case in which GFS2 was improperly setting an inode's i_mode, potentially granting access to the wrong users" * tag 'gfs2-4.14.fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/gfs2/linux-gfs2: (29 commits) gfs2: preserve i_mode if __gfs2_set_acl() fails gfs2: don't return ENODATA in __gfs2_xattr_set unless replacing GFS2: Fix non-recursive truncate bug gfs2: constify rhashtable_params GFS2: Fix gl_object warnings GFS2: Fix up some sparse warnings gfs2: Silence gcc format-truncation warning GFS2: Withdraw for IO errors writing to the journal or statfs gfs2: fix slab corruption during mounting and umounting gfs file system gfs2: forcibly flush ail to relieve memory pressure gfs2: Clean up waiting on glocks gfs2: Defer deleting inodes under memory pressure gfs2: gfs2_evict_inode: Put glocks asynchronously gfs2: Get rid of gfs2_set_nlink gfs2: gfs2_glock_get: Wait on freeing glocks gfs2: Fix trivial typos GFS2: Delete debugfs files only after we evict the glocks GFS2: Don't waste time locking lru_lock for non-lru glocks GFS2: Don't bother trying to add rgrps to the lru list GFS2: Clear gl_object when deleting an inode in gfs2_delete_inode ...

X722 devices use the AdminQ to access the NVM, and this requires taking the AdminQ lock. Because of this, we lock the AdminQ during i40e_read_nvm(), which is also called in places where the lock is already held, such as the firmware update path which wants to lock once and then unlock when finished after performing several tasks. Although this should have only affected X722 devices, commit 96a39aed ("i40e: Acquire NVM lock before reads on all devices", 2016-12-02) added locking for all NVM reads, regardless of device family. This resulted in us accidentally causing NVM acquire timeouts on all devices, causing failed firmware updates which left the eeprom in a corrupt state. Create unsafe non-locked variants of i40e_read_nvm_word and i40e_read_nvm_buffer, __i40e_read_nvm_word and __i40e_read_nvm_buffer respectively. These variants will not take the NVM lock and are expected to only be called in places where the NVM lock is already held if needed. Since the only caller of i40e_read_nvm_buffer() was in such a path, remove it entirely in favor of the unsafe version. If necessary we can always add it back in the future. Additionally, we now need to hold the NVM lock in i40e_validate_checksum because the call to i40e_calc_nvm_checksum now assumes that the NVM lock is held. We can further move the call to read I40E_SR_SW_CHECKSUM_WORD up a bit so that we do not need to acquire the NVM lock twice. This should resolve firmware updates and also fix potential raise that could have caused the driver to report an invalid NVM checksum upon driver load.

We check tx avail through vhost_enable_notify() in the past which is wrong since it only checks whether or not guest has filled more available buffer since last avail idx synchronization which was just done by vhost_vq_avail_empty() before. What we really want is checking pending buffers in the avail ring. Fix this by calling vhost_vq_avail_empty() instead. This issue could be noticed by doing netperf TCP_RR benchmark as client from guest (but not host). With this fix, TCP_RR from guest to localhost restores from 1375.91 trans per sec to 55235.28 trans per sec on my laptop (Intel(R) Core(TM) i7-5600U CPU @ 2.60GHz).

This will also permit to register an of_node mdio-mux that lacks a direct owning device. For example a mdio-mux which is a subnode of a real device.

When an RxRPC service packet comes in, the target connection is looked up by an rb-tree search under RCU and a read-locked seqlock; the seqlock retry check is, however, currently skipped if we got a match, but probably shouldn't be in case the connection we found gets replaced whilst we're doing a search. Make the lookup procedure always go through need_seqretry(), even if the lookup was successful. This makes sure we always pick up on a write-lock event. On the other hand, since we don't take a ref on the object, but rely on RCU to prevent its destruction after dropping the seqlock, I'm not sure this is necessary.

This code is no longer used, the logging function was changed by commit fbca1647 ("net: stmmac: Use the right logging function in stmmac_mdio_register"). It was previously showing information about the type of the IRQ, if it's polled, ignored or a normal interrupt. As we don't want information loss, I have moved this code to phy_attached_print().

The wrong register is checked for the Tx flow control bit, it should have been maccfg1 not maccfg2. This went unnoticed for so long probably because the impact is hardly visible, not to mention the tangled code from adjust_link(). First, link flow control (i.e. handling of Rx/Tx link level pause frames) is disabled by default (needs to be enabled via 'ethtool -A'). Secondly, maccfg2 always returns 0 for tx_flow_oldval (except for a few old boards), which results in Tx flow control remaining always on once activated.

Pull power management updates from Rafael Wysocki: "This time (again) cpufreq gets the majority of changes which mostly are driver updates (including a major consolidation of intel_pstate), some schedutil governor modifications and core cleanups. There also are some changes in the system suspend area, mostly related to diagnostics and debug messages plus some renames of things related to suspend-to-idle. One major change here is that suspend-to-idle is now going to be preferred over S3 on systems where the ACPI tables indicate to do so and provide requsite support (the Low Power Idle S0 _DSM in particular). The system sleep documentation and the tools related to it are updated too.

Florian Fainelli says: ==================== net: dsa: Allow switch drivers to indicate number of TX queues This patch series extracts the parts of the patch set that are likely not to be controversial and actually bringing multi-queue support to DSA-created network devices. With these patches, we can now use sch_multiq as documented under Documentation/networking/multique.txt and let applications dedice the switch port output queue they want to use. Currently only Broadcom tags utilize that information. Resending based on David's feedback regarding the patches not in patchwork. Changes in v2: - use a proper define for the number of TX queues in bcm_sf2.c (Andrew) Changes from RFC: - dropped the ability to configure RX queues since we don't do anything with those just yet - dropped the patches that dealt with binding the DSA slave network devices queues with their master network devices queues this will be worked on separately. ==================== Signed-off-by: NDavid S.
