2010-07-03glamo-mci: add a "nonremovable" field to glamo_mmc_platform_dataThibaut Girka
On the FR, the µSD can't be removed without removing the battery first. So, we can safely assume that the µSD is not removable. This patch make the MMC subsystem know that the card isn't removable if the new "nonremovable" field in the platform data is true. This affects, amongst other things, the suspend/resume process, the default behaviour being to remove the card (after syncind any mounted FS) on suspend, and re-detect it on resume, to prevent errors when removing the card while the device is suspended.
2010-07-03glamo-core: use debugfs instead of sysfs for the 'regs' nodeThibaut Girka
Use debugfs, which is better-suited than sysfs for the 'regs' node. Also change the expected format from decimal to hexadecimal numbers.
2010-07-03glamo-mci: enable irq line sooner to fix resumeThibaut Girka
mmc_resume_host may send commands to the MMC host, so, the IRQ line have to be re-enabled before the mmc_resume_host call. Otherwise, the call may hang, preventing the device from fully waking up.

2010-06-23glamo: Move subdrivers to appropriate directoriesThibaut Girka
Instead of staying in drivers/mfd/glamo, the glamo subdrivers have been moved to the appropriate directories. Additionally, config options were renamed as follows: * MFD_GLAMO stays the same * MFD_GLAMO_MCI becomes MMC_GLAMO * MFD_GLAMO_GPIO becomes GPIO_GLAMO * MFD_GLAMO_FB becomes FB_GLAMO

2010-06-19glamo-mci: safer probeThibaut Girka
Calls mmc_host_disable instead of mmc_host_lazy_disable if an error occurs, thus avoiding to schedule a delayed work that would end up using free'd objects.
2010-06-19glamo-mci: Make use of mmc_host_enable/disable instead of custom timer.Thibaut Girka
A custom timer was used to suspend the mmc host when idle. MMC core now provides a generic way to do that.
2010-06-10glamo-mci: drop unused IRQ polling codeThibaut Girka
host->irq_works is always true, so, the IRQ polling function in glamo-mci.c never gets called. Furthermore, according to Lars, it was only here for very early prototypes of the glamo chip. So, there should be no issue in dropping it.

Now we have a set of nested attributes: IFLA_VFINFO_LIST (NESTED) IFLA_VF_INFO (NESTED) IFLA_VF_MAC IFLA_VF_VLAN IFLA_VF_TX_RATE This allows a single set to operate on multiple attributes if desired. Among other things, it means a dump can be replayed to set state. The current interface has yet to be released, so this seems like something to consider for 2.6.34.

2010-05-16tcp: fix MD5 (RFC2385) supportEric Dumazet
TCP MD5 support uses percpu data for temporary storage. It currently disables preemption so that same storage cannot be reclaimed by another thread on same cpu. We also have to make sure a softirq handler wont try to use also same context. Various bug reports demonstrated corruptions. Fix is to disable preemption and BH.

2010-05-15 MIPS FPU emulator: allow Cause bits of FCSR to be writeable by ctc1Shane McDonald
In the FPU emulator code of the MIPS, the Cause bits of the FCSR register are not currently writeable by the ctc1 instruction. In odd corner cases, this can cause problems. For example, a case existed where a divide-by-zero exception was generated by the FPU, and the signal handler attempted to restore the FPU registers to their state before the exception occurred. In this particular setup, writing the old value to the FCSR register would cause another divide-by-zero exception to occur immediately. The solution is to change the ctc1 instruction emulator code to allow the Cause bits of the FCSR register to be writeable. This is the behaviour of the hardware that the code is emulating. This problem was found by Shane McDonald, but the credit for the fix goes to Kevin Kissell. In Kevin's words: I submit that the bug is indeed in that ctc_op: case of the emulator. The Cause bits (17:12) are supposed to be writable by that instruction, but the CTC1 emulation won't let them be updated by the instruction. I think that actually if you just completely removed lines 387-388 [...] things would work a good deal better. At least, it would be a more accurate emulation of the architecturally defined FPU. If I wanted to be really, really pedantic (which I sometimes do), I'd also protect the reserved bits that aren't necessarily writable.
