2024-04-18btrfs: remove colon from messages with stateDavid Sterba
The message format in syslog is usually made of two parts: prefix ":" message Various tools parse the prefix up to the first ":". When there's an additional status of a btrfs filesystem like [5.199782] BTRFS info (device nvme1n1p1: state M): use zstd compression, level 9 where 'M' is for remount, there's one more ":" that does not conform to the format. Remove it. Reviewed-by: Anand Jain <anand.jain@oracle.com> Signed-off-by: David Sterba <dsterba@suse.com>

2024-04-17Merge branch 'svm' of https://github.com/kvm-x86/linux into HEADPaolo Bonzini
Clean up SVM's enter/exit assembly code so that it can be compiled without OBJECT_FILES_NON_STANDARD. The "standard" __svm_vcpu_run() can't be made 100% bulletproof, as RBP isn't restored on #VMEXIT, but that's also the case for __vmx_vcpu_run(), and getting "close enough" is better than not even trying. As for SEV-ES, after yet another refresher on swap types, I realized KVM can simply let the hardware restore registers after #VMEXIT, all that's missing is storing the current values to the host save area (they are swap type B). This should provide 100% accuracy when using stack frames for unwinding, and requires less assembly. In between, build the SEV-ES code iff CONFIG_KVM_AMD_SEV=y, and yank out "support" for 32-bit kernels in __svm_sev_es_vcpu_run, which was unnecessarily polluting the code for a configuration that is disabled at build time.

2024-04-17netfilter: nf_tables: restore set elements when delete set failsPablo Neira Ayuso
From abort path, nft_mapelem_activate() needs to restore refcounters to the original state. Currently, it uses the set->ops->walk() to iterate over these set elements. The existing set iterator skips inactive elements in the next generation, this does not work from the abort path to restore the original state since it has to skip active elements instead (not inactive ones). This patch moves the check for inactive elements to the set iterator callback, then it reverses the logic for the .activate case which needs to skip active elements. Toggle next generation bit for elements when delete set command is invoked and call nft_clear() from .activate (abort) path to restore the next generation bit.

The recently added check to figure out if a fault happened on gmap ASCE dereferences the gmap pointer in lowcore without checking that it is not NULL. For all non-KVM processes the pointer is NULL, so that some value from lowcore will be read. With the current layouts of struct gmap and struct lowcore the read value (aka ASCE) is zero, so that this doesn't lead to any observable bug; at least currently.

2024-04-17drm/i915: Carve up struct intel_dpll_hw_stateVille Syrjälä
struct intel_dpll_hw_state has a spot for all possible PLL registers across all platforms (well, apart from cx0/snps). This makes it rather confusing when trying to figure out which members belong to which platform(s). Split the struct up into five different platform specific sub-structures. For now this will actually increase the size a little bit as we have to duplicate a few members from skl to icl, but that will be remedied soon when we turn the thing into a union.
