2009-12-02modules: don't export section names of empty sections via sysfsHelge Deller
On the parisc architecture we face for each and every loaded kernel module this kernel "badness warning": sysfs: cannot create duplicate filename '/module/ac97_bus/sections/.text' Badness at fs/sysfs/dir.c:487 Reason for that is, that on parisc all kernel modules do have multiple .text sections due to the usage of the -ffunction-sections compiler flag which is needed to reach all jump targets on this platform. An objdump on such a kernel module gives: Sections: Idx Name Size VMA LMA File off Algn 0 .note.gnu.build-id 00000024 00000000 00000000 00000034 2**2 CONTENTS, ALLOC, LOAD, READONLY, DATA 1 .text 00000000 00000000 00000000 00000058 2**0 CONTENTS, ALLOC, LOAD, READONLY, CODE 2 .text.ac97_bus_match 0000001c 00000000 00000000 00000058 2**2 CONTENTS, ALLOC, LOAD, READONLY, CODE 3 .text 00000000 00000000 00000000 000000d4 2**0 CONTENTS, ALLOC, LOAD, READONLY, CODE ... Since the .text sections are empty (size of 0 bytes) and won't be loaded by the kernel module loader anyway, I don't see a reason why such sections need to be listed under /sys/module/<module_name>/sections/<section_name> either. The attached patch does solve this issue by not exporting section names which are empty.

2009-12-02[ARM] pxamci: call mmc_remove_host() before freeing resourcesDaniel Mack
mmc_remove_host() will cause the mmc core to switch off the bus power by eventually calling pxamci_set_ios(). This function uses the regulator or the GPIO which have been freed already. This causes the following Oops on module unload.

2009-12-01rtc-x1205: reset clock to sane state after power failureJohannes Weiner
When detecting power failure, the probe function would reset the clock time to defined state. However, the clock's _date_ might still be bogus and a subsequent probe fails when sanity-checking these values. Change the power-failure fixup code to do a full setting of rtc_time, including a valid date.

2009-12-01rtc-x1205: fix rtc_time to y2k register value conversionJohannes Weiner
The possible CCR_Y2K register values are 19 or 20 and struct rtc_time's tm_year is in years since 1900. The function translating rtc_time to register values assumes tm_year to be years since first christmas, though, and we end up storing 0 or 1 in the CCR_Y2K register, which the hardware does not refuse to do. A subsequent probing of the clock fails due to the invalid value range in the register, though. [ And if it didn't, reading the clock would yield a bogus year because the function translating registers to tm_year is assuming a register value of 19 or 20. ] This fixes the conversion from years since 1900 in tm_year to the corresponding CCR_Y2K value of 19 or 20.

2009-12-01MIPS: Loongson: Switch from flatmem to sparsememWu Zhangjin
With flatmem hibernation for Loongson will fail, and there are also some other problems such as broken files when using NFS or CIFS / Samba. The config help of sparsemem says: "This option provides some potential performance benefits, along with decreased code complexity." So to avoid the potential problems of FLATMEM, we disable FLATMEM directly and use SPARSEMEM instead.

2009-12-01MIPS: Loongson: Disallow 4kB pagesWu Zhangjin
Currently, with PAGE_SIZE_4KB, the kernel for loongson will hang on: Kernel panic - not syncing: Attempted to kill init! The possible reason is the cache aliases problem: Loongson 2F has 64kb, 4 way L1 Cache, the way size is 16kb, which is bigger then 4kb. so, If using 4kb page size, there is cache aliases problem. To avoid this kind of problem, extra cache flushing. The 2nd possible solution is 16kb page size which avoids cache aliases without the need for extra cache flushes. So we disable 4kB pages until the aliasing issue is solved.

This allows the removal of some #ifdefs. (2) #ifdef'ing out the contents of slow_work_wait_for_items() in moduleless kernels. The four functions related to handling module unloading synchronisation (and their associated variables) could be offloaded into a separate .c file, but each function is only used once and three of them are tiny, so doing so would prevent them from being inlined.

2009-11-30Alpha: Rearrange thread info flags fixing two regressionsMichael Cree
The removal of the TIF_NOTIFY_RESUME flag, commit a583f1b54249b "remove unused TIF_NOTIFY_RESUME flag," resulted in incorrect setting of the unaligned access control flags by the prctl syscall. The re-addition of the TIF_NOTIFY_RESUME flag, commit d0420c83f39f "KEYS: Extend TIF_NOTIFY_RESUME to (almost) all architectures [try #6]" further caused problems, namely incorrect operands to assembler code as evidenced by: AS arch/alpha/kernel/entry.o arch/alpha/kernel/entry.S: Assembler messages: arch/alpha/kernel/entry.S:326: Warning: operand out of range (0x0000000000000406 is not between 0x0000000000000000 and 0x00000000000000ff) Both regressions fixed by (1) rearranging TIF_NOTIFY_RESUME flag to be in lower 8 bits of the thread info flags, and (2) making sure that ALPHA_UAC_SHIFT matches the rearrangement of the thread info flags.

This patch adds the vendor and device id for the Mobilcom Debitel UMTS surf stick (a.k.a. 4G Systems XSStick W14, MobiData MBD-200HU, ...). To see these ids, you need to switch the stick to modem operation first with the help of usb_modeswitch. This makes it switch from 1c9e:f000 to 1c9e:9603 and thus be recognized by the option driver.

2009-11-30USB: musb: Fix CPPI IRQs not being signaledDaniel Glöckner
On tx channel abort a cppi interrupt is generated for a short time by setting the lowest bit of the TCPPICOMPPTR register. It is then reset immediately by clearing the bit. When the interrupt handler is run, it does not detect an interrupt in the TCPPIMSKSR or RCPPIMSKSR registers and thus exits early without writing the TCPPIEOIR register. It appears that this inhibits further cppi interrupts until the handler is called by chance, f.ex. from davinci_interrupt(). By moving the unmasking of the interrupt below the writes to TCPPICOMPPTR, no interrupt is generated and no write to TCPPIEOIR is necessary.

In gadget mode the answer to a control request should be followed by a zero-length packet if the amount transferred is an exact multiple of the endpoint's packet size and the requests has its "zero" flag set. This patch prevents the request from being immediately removed from the queue when a control IN transfer ends on a full packet and "zero" is set. The next time ep0_txstate is entered, a zero-length packet is queued and the request is removed as fifo_count is 0.

2009-11-30USB: ftdi_sio: Keep going when write errors are encountered.Eric W. Biederman
The use of urb->actual_length to update tx_outstanding_bytes implicitly assumes that the number of bytes actually written is the same as the number of bytes we tried to write. On error that assumption is violated so just use transfer_buffer_length the number of bytes we intended to write to the device. If an error occurs we need to fall through and call usb_serial_port_softint to wake up processes waiting in tty_wait_until_sent. Signed-off-by: Eric W.

2009-11-30USB: musb_gadget: fix STALL handlingSergei Shtylyov
The driver incorrectly cancels the mass-storage device CSW request (which leads to device reset) due to giving back URB at the head of endpoint's queue after sending each STALL handshake; stop doing that and start checking for the queue being non-empty before stalling an endpoint and disallowing stall in such case in musb_gadget_set_halt() like the other gadget drivers do. Moreover, the driver starts Rx request despite of the endpoint being halted -- fix this by moving the SendStall bit check from musb_g_rx() to rxstate(). And we also sometimes get into rxstate() with DMA still active after clearing an endpoint's halt (not clear why), so bail out in this case, similarly to what txstate() does... While at it, also do the following changes : - in musb_gadget_set_halt(), remove pointless Tx FIFO flushing (the driver does not allow stalling with non-empty Tx FIFO anyway); - in rxstate(), stop pointlessly zeroing the 'csr' variable; - in musb_gadget_set_halt(), move the 'done' label to a more proper place; - in musb_g_rx(), eliminate the 'done' label completely...

2009-11-30USB: EHCI: don't send Clear-TT-Buffer following a STALLAlan Stern
This patch (as1304) fixes a regression in ehci-hcd. Evidently some hubs don't handle Clear-TT-Buffer requests correctly, so we should avoid sending them when they don't appear to be absolutely necessary. The reported symptom is that output on a downstream audio device cuts out because the hub stops relaying isochronous packets. The patch prevents Clear-TT-Buffer requests from being sent following a STALL handshake. In theory a STALL indicates either that the downstream device sent a STALL or that no matching TT buffer could be found. In either case, the transfer is completed and the TT buffer does not remain busy, so it doesn't need to be cleared. Also, the patch fixes a minor flaw in the code that actually sends the Clear-TT-Buffer requests. Although the pipe direction isn't really used for control transfers, it should be a Send rather than a Receive.
