2024-11-07staging: gpib: Correct check for max secondary addressDave Penkler
GPIB secondary addresses can be between 0 and 31 inclusive unlike primary addresses where address 31 is not a valid device address. When 31 is used as a primary talk address it forms the UNT (Untalk) command and when used as a listener address it forms the UNL (Unlisten) commmand. The library was incorrectly not allowing a secondary address with a value of 31 to be used.

2024-11-07media: ipu6: optimize the IPU6 MMU mapping flowBingbu Cao
ipu6_mmu_map() operated on a per-page basis, it leads frequent spin_lock/unlock() and clflush_cache_range() for each page, it will cause inefficiencies especially when handling dma-bufs with large number of pages. However, the pages are likely concentrated pages by IOMMU DMA driver, IPU MMU driver can map the concentrated pages into less entries in l1 table. This change enhances ipu6_mmu_map() with batching process multiple contiguous pages. It significantly reduces calls for spin_lock/unlock and clflush_cache_range() and improve the performance.

l2_map() and l2_unmap() are better to be grouped together. l2_unmap() will soon be called from l2_map() for mapping optimization.
