2018-03-28iwlwifi: mvm: check if mac80211_queue is valid in iwl_mvm_disable_txqLuca Coelho
Sometimes iwl_mvm_disable_txq() may be called with mac80211_queue == IEEE80211_INVAL_HW_QUEUE, and this would cause us to use BIT(0xFF) which is way too large for the u16 we used to store it in hw_queue_to_mac820211. If this happens the following UBSAN warning will be generated: [ 167.185167] UBSAN: Undefined behaviour in drivers/net/wireless/intel/iwlwifi/mvm/utils.c:838:5 [ 167.185171] shift exponent 255 is too large for 64-bit type 'long unsigned int' Fix that by checking that it is not IEEE80211_INVAL_HW_QUEUE and, while at it, add a warning if the queue number is larger than IEEE80211_MAX_QUEUES.

2018-03-28x86/boot: Fix SEV boot failure from change to __PHYSICAL_MASK_SHIFTTom Lendacky
In arch/x86/boot/compressed/kaslr_64.c, CONFIG_AMD_MEM_ENCRYPT support was initially #undef'd to support SME with minimal effort. When support for SEV was added, the #undef remained and some minimal support for setting the encryption bit was added for building identity mapped pagetable entries. Commit b83ce5ee9147 ("x86/mm/64: Make __PHYSICAL_MASK_SHIFT always 52") changed __PHYSICAL_MASK_SHIFT from 46 to 52 in support of 5-level paging. This change resulted in SEV guests failing to boot because the encryption bit was no longer being automatically masked out. The compressed boot path now requires sme_me_mask to be defined in order for the pagetable functions, such as pud_present(), to properly mask out the encryption bit (currently bit 47) when evaluating pagetable entries. Add an sme_me_mask variable in arch/x86/boot/compressed/mem_encrypt.S, which is set when SEV is active, delete the #undef CONFIG_AMD_MEM_ENCRYPT from arch/x86/boot/compressed/kaslr_64.c and use sme_me_mask when building the identify mapped pagetable entries.

2018-03-28x86/platform/uv/BAU: Add APIC idt entryAndrew Banman
BAU uses the old alloc_initr_gate90 method to setup its interrupt. This fails silently as the BAU vector is in the range of APIC vectors that are registered to the spurious interrupt handler. As a consequence BAU broadcasts are not handled, and the broadcast source CPU hangs. Update BAU to use new idt structure.
