2012-09-14MIPS: Malta: Remove RTC Data Mode bootstrap breakageMaciej W. Rozycki
YAMON requires and enforces the RTC Data Mode (Register B, DM bit) to binary, that is the bit is set every time the board goes through the firmware bootstrap sequence. Likewise its calendar manipulation commands interpret or set the RTC registers unconditionally as binary, never actually checking what the value of the DM bit is, under the (correct) assumption that it has been previously set, to indicate the binary mode. A change to Linux a while ago however introduced a platform-specific tweak that clears that bit and therefore forces the data mode to BCD. This causes clock corruption and misinterpretation that has to be fixed up by user-mode tools in system startup scripts as the initial clock is often incorrect according to the BCD interpretation forced. This change removes the hack; a comment included refers to alarm code, but even if it was broken at one point by requiring the BCD mode, it should have been trivially corrected and even if not, given how rarely the alarm feature is used, that was not really a reasonable justification to break the system clock that is indeed used by virtually everything. And either way the alarm code has been since fixed anyway. Signed-off-by: Maciej W.

2012-08-17MIPS: Synchronize MIPS count one CPU at a timeJayachandran C
The current implementation of synchronise_count_{master,slave} blocks slave CPUs in early boot until all of them come up. This no longer works because blocking a CPU with interrupts off after notifying the CPU to be online causes problems with the current kernel. Specifically, after the workqueue changes (commit a08489c569dc1 "Pull workqueue changes from Tejun Heo") the CPU_ONLINE notification callback workqueue_cpu_up_callback() will hang on wait_for_completion(&idle_rebind.done), if the slave CPUs are blocked for synchronize_count_slave(). The changes are to update synchronize_count_{master,slave}() to handle one CPU at a time and to call synchronise_count_master() in __cpu_up() so that the CPU_ONLINE notification goes out only after the COP0 COUNT register is synchronized.

2012-08-17MIPS: BCM63xx: Fix SPI message control register handling for BCM6338/6348.Florian Fainelli
BCM6338 and BCM6348 have a message control register width of 8 bits, instead of 16-bits like what the SPI driver assumes right now. Also the SPI message type shift value of 14 is actually 6 for these SoCs. This resulted in transmit FIFO corruption because we were writing 16-bits to an 8-bits wide register, thus spanning on the first byte of the transmit FIFO, which had already been filed in bcm63xx_spi_fill_txrx_fifo(). Fix this by passing the message control register width and message type shift through platform data back to the SPI driver so that it can use it properly.

Both the CIU and GPIO interrupt domains were somewhat screwed up. For the CIU domain, we need to call irq_domain_associate() for each of the preassigned irq numbers. For the GPIO domain, we were applying the register bit offset in octeon_irq_gpio_xlat, but it should be done in octeon_irq_gpio_map instead. Also: Reserve all 8 'core' irqs for the 'core' irq_chip so that they don't get used by the other domains. Remove unused OCTEON_IRQ_* symbols.

2012-07-26posix_types.h: Cleanup stale __NFDBITS and related definitionsJosh Boyer
Recently, glibc made a change to suppress sign-conversion warnings in FD_SET (glibc commit ceb9e56b3d1). This uncovered an issue with the kernel's definition of __NFDBITS if applications #include <linux/types.h> after including <sys/select.h>. A build failure would be seen when passing the -Werror=sign-compare and -D_FORTIFY_SOURCE=2 flags to gcc. It was suggested that the kernel should either match the glibc definition of __NFDBITS or remove that entirely. The current in-kernel uses of __NFDBITS can be replaced with BITS_PER_LONG, and there are no uses of the related __FDELT and __FDMASK defines. Given that, we'll continue the cleanup that was started with commit 8b3d1cda4f5f ("posix_types: Remove fd_set macros") and drop the remaining unused macros. Additionally, linux/time.h has similar macros defined that expand to nothing so we'll remove those at the same time.

Pull networking changes from David S Miller: 1) Remove the ipv4 routing cache. Now lookups go directly into the FIB trie and use prebuilt routes cached there. No more garbage collection, no more rDOS attacks on the routing cache. Instead we now get predictable and consistent performance, no matter what the pattern of traffic we service. This has been almost 2 years in the making. Special thanks to Julian Anastasov, Eric Dumazet, Steffen Klassert, and others who have helped along the way. I'm sure that with a change of this magnitude there will be some kind of fallout, but such things ought the be simple to fix at this point. Luckily I'm not European so I'll be around all of August to fix things :-) The major stages of this work here are each fronted by a forced merge commit whose commit message contains a top-level description of the motivations and implementation issues. 2) Pre-demux of established ipv4 TCP sockets, saves a route demux on input. 3) TCP SYN/ACK performance tweaks from Eric Dumazet. 4) Add namespace support for netfilter L4 conntrack helpers, from Gao Feng. 5) Add config mechanism for Energy Efficient Ethernet to ethtool, from Yuval Mintz. 6) Remove quadratic behavior from /proc/net/unix, from Eric Dumazet. 7) Support for connection tracker helpers in userspace, from Pablo Neira Ayuso. 8) Allow userspace driven TX load balancing functions in TEAM driver, from Jiri Pirko. 9) Kill off NLMSG_PUT and RTA_PUT macros, more gross stuff with embedded gotos. 10) TCP Small Queues, essentially minimize the amount of TCP data queued up in the packet scheduler layer. Whereas the existing BQL (Byte Queue Limits) limits the pkt_sched --> netdevice queuing levels, this controls the TCP --> pkt_sched queueing levels. From Eric Dumazet. 11) Reduce the number of get_page/put_page ops done on SKB fragments, from Alexander Duyck. 12) Implement protection against blind resets in TCP (RFC 5961), from Eric Dumazet. 13) Support the client side of TCP Fast Open, basically the ability to send data in the SYN exchange, from Yuchung Cheng. Basically, the sender queues up data with a sendmsg() call using MSG_FASTOPEN, then they do the connect() which emits the queued up fastopen data. 14) Avoid all the problems we get into in TCP when timers or PMTU events hit a locked socket. The TCP Small Queues changes added a tcp_release_cb() that allows us to queue work up to the release_sock() caller, and that's what we use here too. From Eric Dumazet. 15) Zero copy on TX support for TUN driver, from Michael S.
