On smb2_async_writev(), set CIFS_COMPRESS_REQ on request flags if should_compress() returns true. On smb_send_rqst() check the flags, and compress and send the request to the server. (*) If the compression fails with -EMSGSIZE (i.e. compressed size is >= uncompressed size), the original uncompressed request is sent instead.

Pull kvm fix from Paolo Bonzini: "Do not always honor guest PAT on CPUs that support self-snoop. This triggers an issue in the bochsdrm driver, which used ioremap() instead of ioremap_wc() to map the video RAM. The revert lets video RAM use the WB memory type instead of the slower UC memory type" * tag 'for-linus-6.11' of git://git.kernel.org/pub/scm/virt/kvm/kvm: Revert "KVM: VMX: Always honor guest PAT on CPUs that support self-snoop"

Paolo Bonzini authored
This reverts commit 377b2f35. This caused a regression with the bochsdrm driver, which used ioremap() instead of ioremap_wc() to map the video RAM. After the commit, the WB memory type is used without the IGNORE_PAT, resulting in the slower UC memory type. In fact, UC is slow enough to basically cause guests to not boot... but only on new processors such as Sapphire Rapids and Cascade Lake. Coffee Lake for example works properly, though that might also be an effect of being on a larger, more NUMA system. The driver has been fixed but that does not help older guests. Until we figure out whether Cascade Lake and newer processors are working as intended, revert the commit. Long term we might add a quirk, but the details depend on whether the processors are working as intended: for example if they are, the quirk might reference bochs-compatible devices, e.g. in the name and documentation, so that userspace can disable the quirk by default and only leave it enabled if such a device is being exposed to the guest. If instead this is actually a bug in CLX+, then the actions we need to take are different and depend on the actual cause of the bug. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

As Jann points out, PFN mappings are special, because unlike normal memory mappings, there is no lifetime information associated with the mapping - it is just a raw mapping of PFNs with no reference counting of a 'struct page'. That's all very much intentional, but it does mean that it's easy to mess up the cleanup in case of errors. Yes, a failed mmap() will always eventually clean up any partial mappings, but without any explicit lifetime in the page table mapping itself, it's very easy to do the error handling in the wrong order. In particular, it's easy to mistakenly free the physical backing store before the page tables are actually cleaned up and (temporarily) have stale dangling PTE entries. To make this situation less error-prone, just make sure that any partial pfn mapping is torn down early, before any other error handling.

There is a real deadlock as well as sleeping in atomic() bug in here, if the bo put happens to be the last ref, since bo destruction wants to grab the same spinlock and sleeping locks. Fix that by dropping the ref using xe_bo_put_deferred(), and moving the final commit outside of the lock. Dropping the lock around the put is tricky since the bo can go out of scope and delete itself from the list, making it difficult to navigate to the next list entry.
