Hardware with MCA bus is limited to 386 and 486 class machines that are now 20+ years old and typically with less than 32MB of memory. A quick search on the internet, and you see that even the MCA hobbyist/enthusiast community has lost interest in the early 2000 era and never really even moved ahead from the 2.4 kernels to the 2.6 series. This deletes anything remaining related to CONFIG_MCA from core kernel code and from the x86 architecture. There is no point in carrying this any further into the future. One complication to watch for is inadvertently scooping up stuff relating to machine check, since there is overlap in the TLA name space (e.g. arch/x86/boot/mca.c).

The support for CONFIG_MCA is being removed, since the 20 year old hardware simply isn't capable of meeting today's software demands on CPU and memory resources. This commit removes the MCA specific SCSI drivers, and the MCA specific portions of code in dual role ISA/MCA drivers. Also, the MCA specific SCSI documentation is removed.

Change the TX ring scheme such that the number of rings for untagged packets and for tagged packets (per each of the vlan priorities) is the same, unlike the current situation where for tagged traffic there's one ring per priority and for untagged rings as the number of core. Queue selection is done as follows: If the mqprio qdisc is operates on the interface, such that the core networking code invoked the device setup_tc ndo callback, a mapping of skb->priority => queue set is forced - for both, tagged and untagged traffic. Else, the egress map skb->priority => User priority is used for tagged traffic, and all untagged traffic is sent through tx rings of UP 0. The patch follows the convergence of discussing that issue with John Fastabend over this thread http://comments.gmane.org/gmane.linux.network/229877 Cc: John Fastabend <john.r.fastabend@intel.com> Cc: Liran Liss <liranl@mellanox.com> Signed-off-by: NAmir Vadai <amirv@mellanox.com> Signed-off-by: NDavid S.

netdev_alloc_skb() is used by networks driver in their RX path to allocate an skb to receive an incoming frame. With recent skb->head_frag infrastructure, it makes sense to change netdev_alloc_skb() to use build_skb() and a frag allocator.

The code seems to want to look at the last byte where the HW puts some information. Since the skb->data area is never seen by the HW I guess it does not work as expected. We pass the page address to the HW so I *think* in order to get to the last byte where the information might be one should use the page buffer and take a look. This is of course not more than just compile tested.

According to the comment, errata 23 says that the memory we allocate can't cross a 64KiB boundary. In case of jumbo frames we allocate complete pages which can never cross the 64KiB boundary because PAGE_SIZE should be a multiple of 64KiB so we stop either before the boundary or start after it but never cross it. Furthermore the check seems bogus because it looks at skb->data which is not seen by the HW at all because we only pass the DMA address of the page we allocated. So I *think* the workaround is not required here.

Pull networking tree from David Miller: 1) ptp_pch driver build broke during this merge window due to missing slab.h header, fix from Geery Uytterhoeven. 2) If ipset passes in a bogus hash table size we crash because the size is not validated properly. Compounding this, gcc-4.7 can miscompile ipset such that even when the user specifies legitimate parameters the tool passes in an out-of-range size to the kernel. Fix from Jozsef Kadlecsik. 3) Users have reported that the netdev watchdog can trigger with pch_gbe devices, and it turns out this is happening because of races in the TX path of the driver leading to the transmitter hanging. Fix from Eric Dumazet, reported and tested by Andy Cress. 4) Novatel USB551L devices match the generic class entries for the cdc ethernet USB driver, but they don't work because they have generic descriptors and thus need FLAG_WWAN to function properly. Add the necessary ID table entry to fix this, from Dan Williams. 5) A recursive locking fix in the USBNET driver added a new problem, in that packet list traversal is now racy and we can thus access unlinked SKBs and crash. Avoid this situation by adding some extra state tracking, from Ming Lei. 6) The rtlwifi conversion to asynchronous firmware loading is racy, fix by reordering the probe procedure. From Larry Finger. Fixes: https://bugzilla.kernel.org/show_bug.cgi?id=43187 7) Fix regressions with bluetooth keyboards by notifying userland properly when the security level changes, from Gustavo Padovan. 8) Bluetooth needs to make sure device connected events are emitted before other kinds of events, otherwise userspace will think there is no baseband link yet and therefore abort the sockets associated with that connection. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: netfilter: ipset: fix hash size checking in kernel ptp_pch: Add missing #include <linux/slab.h> pch_gbe: fix transmit races cdc_ether: add Novatel USB551L device IDs for FLAG_WWAN usbnet: fix skb traversing races during unlink(v2) Bluetooth: mgmt: Fix device_connected sending order Bluetooth: notify userspace of security level change rtlwifi: fix for race condition when firmware is cached

First, we were at risk of handling thread-info flags, in particular do_signal(), when returning from kernel space. This could happen after a failed kernel_execve(), or when forking a kernel thread. The fix is to test in do_work_pending() for user_mode() and return immediately if so; we already had this test for one of the flags, so I just hoisted it to the top of the function. Second, if a ptraced process updated the callee-saved registers in the ptregs struct and then processed another thread-info flag, we would overwrite the modifications with the original callee-saved registers. To fix this, we add a register to note if we've already saved the registers once, and skip doing it on additional passes through the loop. To avoid a performance hit from the couple of extra instructions involved, I modified the GET_THREAD_INFO() macro to be guaranteed to be one instruction, then bundled it with adjacent instructions, yielding an overall net savings.
