This changes large master transfers to do shorter read/write rather than return -EINVAL. User space will now be able to optimistically request a large transfer and get at least some data. This also removes comments suggesting on how to implement large transfers. Current vme_master_* read and write implementations use CPU copies that don't produce burst PCI accesses and subsequently no block transfer on VME bus. In the end overall performance is quiet low and it can't be fixed by doing direct copy to user space. Much easier solution would be to just reuse kernel buffer. Signed-off-by:

This patch enables debugfs file /sys/kernel/debug/ion/heaps/system_shrink to shrink pool and get pool size. This technically enables debugfs shrinking for all heaps, not just the system heap although the system heap is the only one with a shrinker right now. It is already implemented but not complete. This patch completes and enables it. Reading the file returns pool size in page unit and writing the number of pages shrinks pool. It flushes all pages to write zero at the file. Signed-off-by:

This patch shrink page-pool by page unit. The system shrinker calls ion_heap_shrink_count() to get nr_to_scan, and pass it to ion_heap_shrink_scan(). The problem is the return value of ion_heap_shrink_count() is the number of pages but ion_system_heap_shrink(), which is called by ion_heap_shrink_scan(), gets the number of chunk. The main root of this is that ion_page_pool_shrink() returns page count via ion_page_pool_total() if it have to check pool size. But it frees chunks of pages if it have to free pools. This patch first fix ion_page_pool_shrink() to count only pages, not chunks. And then ion_system_heap_shrink() to work on pages. Signed-off-by:

Use eth_zero_addr to assign the zero address to the given address array instead of memset when second argument is address of zero. Note that the 6 in the third argument of memset appears to represent an ethernet address size (ETH_ALEN). The Coccinelle semantic patch that makes this change is as follows: // <smpl> @eth_zero_addr@ expression e; @@ -memset(e,0x00,6); +eth_zero_addr(e); // </smpl> Signed-off-by:
