2008-11-30sdricoh_cs: Add support for Bay Controller devicesSascha Sommer
Some Ricoh SD card readers seems to advertise themselves slightly differently.

2008-11-30mmc: at91_mci: reorder timer setup and mmc_add_host() callNicolas Ferre
As said in function comment mmc_add_host() requires that: "The host must be prepared to start servicing requests before this function completes." During this function, at91_mci_request() can be invoqued without timer beeing setup leading to a kernel Oops. This has been reported inserting this driver as a module.

2008-11-30input: replace spin_lock_bh with spin_lock_irqsave in ml_ff_playbackArjan van de Ven
ml_ff_playback() uses spin_(un)lock_bh. However this function is called with interrupts disabled from erase_effect() in drivers/input/ff-core.c:196. This is not permitted, and will result in a WARN_ON in the bottom half handling code. This patch changes this function to just use spin_lock_irqsave() instead, solving the problem and simplifying the locking logic.

2008-11-30tricky one: hisax sectionsAl Viro
a) hisax_init_pcmcia() needs to be defined only if we have CONFIG_HOTPLUG (no PCMCIA support otherwise) and can be declared __devinit. b) HiSax_inithardware() can go __init c) hisax_register() is passing to checkcard() full-blown hisax_cs_setup_card(): checkcard(i, id, NULL, hisax_d_if->owner, hisax_cs_setup_card); The problem with it is that * hisax_cs_setup_card() is __devinit * hisax_register() is not * hisax_cs_setup_card() is a switch from hell, calling a lot of setup_some_weirdcard() depending on card->typ. _These_ are also __devinit. However, in hisax_register() we have card->typ equal to ISDN_CTYPE_DYNAMIC, which reduces hisax_cs_setup_card() to "nevermind all that crap, just do nothing and return 2". So we add a trimmed-down callback doing just that and passed to checkcard() by hisax_register(). _This_ is non-init (we can stand the impact on .text size).

2008-11-30advansys fix on ISA-less configsAl Viro
The code if (shost->dma_channel != NO_ISA_DMA) free_dma(shost->dma_channel); in there is triggerable only if we have CONFIG_ISA (we only set ->dma_channel to something other than NO_ISA_DMA under #ifdef CONFIG_ISA). OTOH, free_dma() is not guaranteed to be there in absense of CONFIG_ISA. IOW, driver runs into undefined symbols on PCI-but-not-ISA configs (e.g. on frv) and it's a false positive. Fix: put the entire if () under #ifdef CONFIG_ISA; behaviour doesn't change and dependency on free_dma() disappears for !CONFIG_ISA.

2008-11-28toshiba_acpi: close race in toshiba_acpi driverArjan van de Ven
the toshiba ACPI driver will, in a failure case, free the rfkill state before stopping the polling timer that would use this state. More interesting, in the same failure case handling, it calls the exit function, which also frees the rfkill state, but after stopping the polling. If the race happens, a NULL pointer is passed to rfkill_force_state() which then causes a nice dereference. Fix the race by just not doing the too-early freeing of the rfkill state. This appears to be the cause of a hot issue on kerneloops.org; while I have no solid evidence of that this patch will fix the issue, the race appears rather real.

The s390 implementation of sched_clock uses the store clock instruction and subtracts jiffies_timer_cc. jiffies_timer_cc is a local variable in arch/s390/kernel/time.c and only used for sched_clock and monotonic clock. For historical reasons there is an offset on that value. With todays code this offset is unnecessary. By removing that offset we can get a sched_clock which returns the nanoseconds after time_init. This improves CONFIG_PRINTK_TIME. Since sched_clock is the only user, I have also renamed jiffies_timer_cc to sched_clock_base_cc. In addition, the local variable init_timer_cc is redundant and can be romved as well.

2008-11-27[S390] fix system call parameter functions.Martin Schwidefsky
syscall_get_nr() currently returns a valid result only if the call chain of the traced process includes do_syscall_trace_enter(). But collect_syscall() can be called for any sleeping task, the result of syscall_get_nr() in general is completely bogus. To make syscall_get_nr() work for any sleeping task the traps field in pt_regs is replace with svcnr - the system call number the process is executing. If svcnr == 0 the process is not on a system call path. The syscall_get_arguments and syscall_set_arguments use regs->gprs[2] for the first system call parameter. This is incorrect since gprs[2] may have been overwritten with the system call number if the call chain includes do_syscall_trace_enter. Use regs->orig_gprs2 instead.
