This fixes a bug where the iscsi class/driver did not do a put_device when a sess/conn device was found.

These enums have been separate since the dawn of SAS, mainly because the latter is a procotol only enum and the former includes additional state for libsas. The dichotomy causes endless confusion about which one you should use where and leads to pointless warnings like this: drivers/scsi/mvsas/mv_sas.c: In function 'mvs_update_phyinfo': drivers/scsi/mvsas/mv_sas.c:1162:34: warning: comparison between 'enum sas_device_type' and 'enum sas_dev_type' [-Wenum-compare] Fix by eliminating one of them. The one kept is effectively the sas.h one, but call it sas_device_type and make sure the enums are all properly namespaced with the SAS_ prefix.

Cancelling kiocbs requires adding them to a per kioctx linked list, which is one of the few things we need to take the kioctx lock for in the fast path. But most kiocbs can't be cancelled - so if we just do this lazily, we can avoid quite a bit of locking overhead. While we're at it, instead of using a flag bit switch to using ki_cancel itself to indicate that a kiocb has been cancelled/completed. This lets us get rid of ki_flags entirely.

This removes the only in-tree user of aio retry. This will let us remove the retry code from the aio core. Removing retry is relatively easy as the USB gadget wasn't using it to retry IOs at all. It always fully submitted the IO in the context of the initial io_submit() call. It only used the AIO retry facility to get the submitter's mm context for copying the result of a read back to user space. This is easy to implement with use_mm() and a work struct, much like kvm does with async_pf_execute() for get_user_pages().

This patch fixes partly PAGE_SIZEs of 16K or 64K by adjusting the assembler PTE lookup code and the assembler TEMPALIAS code. Furthermore some data alignments for PAGE_SIZE have been limited to 4K (or less) to not waste too much memory with greater page sizes. As a side note, the palo loader can (currently) only handle up to 10 ELF segments which is fixed with tighter aligning as well. My testings indicated that the ldci command in the sba iommu coding needed adjustment by the PAGE_SHIFT value and that the I/O PDIR Page size was only set to 4K for my machine (C3000). All this fixes partly the boot, but there are still quite some caching problems left. Examples are e.g. the symbios logic driver which is failing: sym0: <896> rev 0x7 at pci 0000:00:0f.0 irq 69 sym0: PA-RISC Firmware, ID 7, Fast-40, SE, parity checking CACHE TEST FAILED: DMA error (dstat=0x81).sym0: CACHE INCORRECTLY CONFIGURED. and the tulip network driver which doesn't seem to work correctly either: Sending BOOTP requests .net eth0: Setting full-duplex based on MII#1 link partner capability of 05e1 ..... timed out! Beside those kernel fixes glibc will need fixes too to be able to handle >4K page sizes. Signed-off-by: NHelge Deller <deller@gmx.de>
