* MIPS: Alchemy: devboards: sit and spin after poweroffManuel Lauss2014-09-221-0/+3
| | | | | | | | | | | On boards which don't support poweroff, systemd complains about this fact. In case poweroff fails, just sit and spin in the wait loop.

| * ARM: 8148/1: flush TLS and thumbee register state during execNathan Lynch2014-09-164-17/+66
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The TPIDRURO and TPIDRURW registers need to be flushed during exec; otherwise TLS information is potentially leaked. TPIDRURO in particular needs careful treatment. Since flush_thread basically needs the same code used to set the TLS in arm_syscall, pull that into a common set_tls helper in tls.h and use it in both places. Similarly, TEEHBR needs to be cleared during exec as well. Clearing its save slot in thread_info isn't right as there is no guarantee that a thread switch will occur before the new program runs. Just setting the register directly is sufficient.

| * ARM: 8137/1: fix get_user BE behavior for target variable with size of 8 bytesVictor Kamensky2014-09-122-11/+75
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | e38361d 'ARM: 8091/2: add get_user() support for 8 byte types' commit broke V7 BE get_user call when target var size is 64 bit, but '*ptr' size is 32 bit or smaller. e38361d changed type of __r2 from 'register unsigned long' to 'register typeof(x) __r2 asm("r2")' i.e before the change even when target variable size was 64 bit, __r2 was still 32 bit. But after e38361d commit, for target var of 64 bit size, __r2 became 64 bit and now it should occupy 2 registers r2, and r3. The issue in BE case that r3 register is least significant word of __r2 and r2 register is most significant word of __r2. But __get_user_4 still copies result into r2 (most significant word of __r2). Subsequent code copies from __r2 into x, but for situation described it will pick up only garbage from r3 register. Special __get_user_64t_(124) functions are introduced. They are similar to corresponding __get_user_(124) function but result stored in r3 register (lsw in case of 64 bit __r2 in BE image). Those function are used by get_user macro in case of BE and target var size is 64bit. Also changed __get_user_lo8 name into __get_user_32t_8 to get consistent naming accross all cases.

| * ARM: 8135/1: Fix in-correct barrier usage in SWP{B} emulationPunit Agrawal2014-09-121-15/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | According to the ARM ARMv7, explicit barriers are necessary when using synchronisation primitives such as SWP{B}. The use of these instructions does not automatically imply a barrier and any ordering requirements by the software must be explicitly expressed with the use of suitable barriers. Based on this, remove the barriers from SWP{B} emulation.

| * ARM: 8133/1: use irq_set_affinity with force=false when migrating irqsSudeep Holla2014-09-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since commit 1dbfa187dad ("ARM: irq migration: force migration off CPU going down") the ARM interrupt migration code on cpu offline calls irqchip.irq_set_affinity() with the argument force=true. At the point of this change the argument had no effect because it was not used by any interrupt chip driver and there was no semantics defined. This changed with commit 01f8fa4f01d8 ("genirq: Allow forcing cpu affinity of interrupts") which made the force argument useful to route interrupts to not yet online cpus without checking the target cpu against the cpu online mask. The following commit ffde1de64012 ("irqchip: gic: Support forced affinity setting") implemented this for the GIC interrupt controller. As a consequence the ARM cpu offline irq migration fails if CPU0 is offlined, because CPU0 is still set in the affinity mask and the validataion against cpu online mask is skipped to the force argument being true. The following first_cpu(mask) selection always selects CPU0 as the target. Solve the issue by calling irq_set_affinity() with force=false from the CPU offline irq migration code so the GIC driver validates the affinity mask against CPU online mask and therefore removes CPU0 from the possible target candidates. Tested on TC2 hotpluging CPU0 in and out. Without this patch the system locks up as the IRQs are not migrated away from CPU0.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ARM: LPAE: drop wrong carry flag correction after adding TTBR1_OFFSET In commit 7fb00c2fca4b6c58be521eb3676cf4b4ba8dde3b ("ARM: 8114/1: LPAE: load upper bits of early TTBR0/TTBR1") part which fixes carrying in adding TTBR1_OFFSET to TTRR1 was wrong: addls ttbr1, ttbr1, #TTBR1_OFFSET adcls tmp, tmp, #0 addls doesn't update flags, adcls adds carry from cmp above: cmp ttbr1, tmp @ PHYS_OFFSET > PAGE_OFFSET? Condition 'ls' means carry flag is clear or zero flag is set, thus only one case is affected: when PHYS_OFFSET == PAGE_OFFSET. It seems safer to remove this fixup.

They use Shuttle Technology EUSB-01/EUSB-S1 chips. The US_FL_SCM_MULT_TARG quirk is needed to allow multiple devices on the SCSI chain to be accessed. Without it only the (single) device with SCSI ID 0 can be used. The standalone converter sold by Entrega had model number U1-SC25. Xircom acquired Entrega and re-branded the product line PortGear. The PortGear USB to SCSI Converter (model PGSCSI) is internally identical to the Entrega product, but later models may use a different USB ID. The Entrega-branded units have USB ID 1645:0007, as does my Xircom PGSCSI, but the Windows and Macintosh drivers also support 085A:0028. Entrega also sold the "Mac USB Dock", which provides two USB ports, a Mac (8-pin mini-DIN) serial port and a SCSI port. It appears to the computer as a four-port hub, USB-serial, and USB-SCSI converters. The USB-SCSI part may have initially used the same ID as the standalone U1-SC25 (1645:0007), but later production used 085A:0026. My Xircom PortGear PGSCSI has bcdDevice=0x0100. Units with bcdDevice=0x0133 probably also exist. This patch adds quirks for 1645:0007, 085A:0026 and 085A:0028. The Windows driver INF file also mentions 085A:0032 "PortStation SCSI Module", but I couldn't find any mention of that actually existing in the wild; perhaps it was cancelled before release?

Only the connectors differ; both have the same USB ID. The US_FL_SCM_MULT_TARG quirk is required to use SCSI devices with ID other than 0. I don't have one of these, but based on the other entries for Shuttle/ SCM-based converters this patch is very likely correct. I used 0x0000 and 0x9999 for bcdDeviceMin and bcdDeviceMax because I'm not sure which bcdDevice value the products use.

This was necessary back when the driver wasn't so careful about keeping track of the controller's state. But now we are careful about it, and the driver knows that when the controller isn't running, no unlinking delay is needed. Furthermore, skipping the unlink step will trigger a BUG() in qh_destroy() when the preceding QH is released, because the link pointer will be non-NULL. Removing the lines that skip the unlinking step and go directly to QH_STATE_IDLE fixes the problem.

This is done to address the case where an ITT is being reused for DataOUT, but the previous command with the same ITT has not yet been acknowledged by ExpStatSN and removed from the per connection command list. This issue was originally manifesting itself by referencing the previous command during ITT lookup, and subsequently hitting the check in iscsit_check_dataout_hdr() for ICF_GOT_LAST_DATAOUT, that resulted in the DataOUT PDU + associated payload being silently dumped.
