* net/fec: fix the .remove codeLothar Waßmann2011-12-081-9/+22
| | | | | | | | | | | | | | | The .remove code is broken in several ways. - mdiobus_unregister() is called twice for the same object in case of dual FEC - phy_disconnect() is being called when the PHY is already disconnected - the requested IRQ(s) are not freed - fec_stop() is being called with the inteface already stopped All of those lead to kernel crashes if the remove function is actually used.

* net/fec: don't munge MAC address from platform dataLothar Waßmann2011-12-081-1/+1
| | | | | | | | | | | | When the MAC address is supplied via platform_data it should be OK as it is and should not be modified in case of a dual FEC setup. Also copying the MAC from platform_data to the single 'macaddr' variable will overwrite the MAC for the first interface in case of a dual FEC setup.

The latter does not need rtl8169_init_ring_indexes because the indexes still contain their original values from the newly allocated network device private data area (i.e. 0). rtl8169_hw_reset is used by: 1. rtl8169_down Helper for rtl8169_close. rtl8169_open explicitely inits the indexes anyway. 2. rtl8169_pcierr_interrupt Indexes are set by rtl8169_reinit_task. 3. rtl8169_interrupt rtl8169_hw_reset is needed when the device goes down. See 1. 4. rtl_shutdown System shutdown handler. Indexes are irrelevant. 5. rtl8169_reset_task Indexes must be set before rtl_hw_start is called. 6. rtl8169_tx_timeout Indexes should not be set. This is the job of rtl8169_reset_task anyway. The removal of rtl8169_hw_reset in rtl8169_tx_timeout and its move in rtl8169_reset_task do not change the analysis.

| | * r8169: Rx FIFO overflow fixes.françois romieu2011-12-051-25/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Realtek has specified that the post 8168c gigabit chips and the post 8105e fast ethernet chips recover automatically from a Rx FIFO overflow. The driver does not need to clear the RxFIFOOver bit of IntrStatus and it should rather avoid messing it. The implementation deserves some explanation: 1. events outside of the intr_event bit mask are now ignored. It enforces a no-processing policy for the events that either should not be there or should be ignored. 2. RxFIFOOver was already ignored in rtl_cfg_infos[RTL_CFG_1] for the whole 8168 line of chips with two exceptions: - RTL_GIGA_MAC_VER_22 since b5ba6d12bdac21bc0620a5089e0f24e362645efd ("use RxFIFO overflow workaround for 8168c chipset."). This one should now be correctly handled. - RTL_GIGA_MAC_VER_11 (8168b) which requires a different Rx FIFO overflow processing. Though it does not conform to Realtek suggestion above, the updated driver includes no change for RTL_GIGA_MAC_VER_12 and RTL_GIGA_MAC_VER_17. Both are 8168b. RTL_GIGA_MAC_VER_12 is common and a bit old so I'd rather wait for experimental evidence that the change suggested by Realtek really helps or does not hurt in unexpected ways. Removed case statements in rtl8169_interrupt are only 8168 relevant. 3. RxFIFOOver is masked for post 8105e 810x chips, namely the sole 8105e (RTL_GIGA_MAC_VER_30) itself.

As a result when a hotkey is pressed it gets stuck in an infinite loop in toshiba_acpi_notify. To fix this, detect whether or not HCI_SYSTEM_EVENT is supported up-front and don't try to read system events if it isn't supported. In addition, limit the number of retries when reading HCI_SYSTEM_EVENT fails so that this loop cannot run unbounded.

This happens if oprofile_arch_init() fails and oprofile switches to the hr timer mode as a fallback. In this case oprofile_arch_exit() is called, but it never was initialized properly which causes the crash. This patch fixes this. oprofile: using timer interrupt.

This effectivly stops time for the duration of the short sleep. Check if sleep_time is positive after all the adjustments have been applied instead since this allows the old_system adjustment in rtc_suspend to have an effect even for short sleep cycles.

The commit added a reset-on-resume quirk because the NEC chipset stopped responding to commands about 30 minutes after a system resume from suspend. We thought it was a chipset issue, but it turns out that the xHCI driver was zeroing out the link TRB after a successful context restore during resume. The host controller would fall off the command ring sometime later, causing it to not respond to new commands. The link TRB issue has been fixed with commit 158886cd2cf4599e04f9b7e10cb767f5f39b14f1 "xHCI: fix bug in xhci_clear_command_ring()", so revert the reset-on-resume quirk, as it's not necessary. Commit df711fc9962b9491af2b92bd0d21ecbfefe4e5fa was marked for stable trees back to 2.6.37, but according to my mail, it has not made it into Linus' tree or the stable trees yet.

However, this also writes zero to the Link TRB, and the ring is mangled. This may cause driver accesses wrong memory address and the result is unpredicted. When clear the command ring, keep the last Link TRB intact, only clear its cycle bit. This should fix the "command ring full" issue reported by Oliver Neukum. This should be backported to stable kernels as old as 2.6.37, since the commit 89821320 "xhci: Fix command ring replay after resume" is merged.
