2012-05-04tty: mxser: local variables should not be exposed globallyH Hartley Sweeten1-1/+1
The variable 'mxser_port_ops' is only referenced in this file and should be marked static to prevent it from being exposed globally.

2012-05-02serial8250: Introduce serial8250_register_8250_port()Magnus Damm1-32/+59
Introduce yet another 8250 registration function. This time it is serial8250_register_8250_port() and it allows us to register 8250 hardware instances using struct uart_8250_port. The new function makes it possible to register 8250 hardware that makes use of 8250 specific callbacks such as ->dl_read() and ->dl_write().

2012-05-018250.c: less than 2400 baud fix.Christian Melki1-4/+5
We noticed that we were loosing data at speed less than 2400 baud. It turned out our (TI16750 compatible) uart with 64 byte outgoing fifo was truncated to 16 byte (bit 5 sets fifo len) when modifying the fcr reg. The input code still fills the buffer with 64 bytes if I remember correctly and thus data is lost. Our fix was to remove whiping of the fcr content and just add the TRIGGER_1 which we want for latency. I can't see why this would not work on less than 2400 always, for all uarts ... Otherwise one would have to make sure the filling of the fifo re-checks the current state of available fifo size (urrk).

The rules used to make 8250_pci "ignore" the PCH uarts are lacking pci subids entries, preventing it to match and thus is breaking serial port support for theses systems.

2012-04-29TTY: n_tty, do not dereference user bufferJiri Slaby1-4/+5
copy_from_read_buf currently copies data to a user buffer and then checks if the data is single EOF. But it checks it by accessing the user buffer. First, the buffer may be changed by other threads of the user program already. Second, it accesses the buffer without any checks. It might be write-only for example. Fix this by inspecting contents of the tty (kernel) buffer instead. Note that "n == 1" is necessary, but not sufficient. But we check later that there is nothing left by "!tty->read_cnt" condition. There is still an issue with the current code that EOF being wrapped to the start of the circular buffer will result in an inappropriate losing of the EOF character. But this is not intended to be fixed by this patch.

When we do this it becomes clear the lock we should be holding is the vc lock, and in fact many of our other helpers are properly invoked this way. We don't at this point guarantee not to race the keyboard code but the results of that appear harmless and that was true before we started as well.

Commit c79396c191bc19 ("mmc: sdhci: prevent card detection activity for non-removable cards") disables card detection where the cards are marked as non-removable. This makes sense, but the implementation detail of calling mmc_card_is_removable() causes some problems, because mmc_card_is_removable() is overloaded with CONFIG_MMC_UNSAFE_RESUME semantics. In the OLPC XO case, we need CONFIG_MMC_UNSAFE_RESUME because our root filesystem is stored on SD, but we also have external SD card slots where we want automatic card detection. Refine the check to only apply to hosts marked as MMC_CAP_NONREMOVABLE, which is defined to mean that the card is *really* nonremovable. This could be revisited in future if we find a way to improve CONFIG_MMC_UNSAFE_RESUME semantics.

2012-04-20VM: add "vm_mmap()" helper functionLinus Torvalds4-14/+7
This continues the theme started with vm_brk() and vm_munmap(): vm_mmap() does the same thing as do_mmap(), but additionally does the required VM locking. This uninlines (and rewrites it to be clearer) do_mmap(), which sadly duplicates it in mm/mmap.c and mm/nommu.c. But that way we don't have to export our internal do_mmap_pgoff() function. Some day we hopefully don't have to export do_mmap() either, if all modular users can become the simpler vm_mmap() instead. We're actually very close to that already, with the notable exception of the (broken) use in i810, and a couple of stragglers in binfmt_elf.

eMMC v4.5 discard operation is significantly different from the existing trim operation because it is not guaranteed to work with the new sanitize operation. Consequently mmc_can_trim() is separated from mmc_can_discard(). Also the new discard operation does not result in the sectors being set to all-zeros, so discard_zeroes_data must not be set. In addition, the new discard has the same timeout as trim, but from v4.5 trim is defined to use the hc timeout. The timeout calculation is adjusted accordingly. Fixes apply to linux 3.2 on.

This reverts commit cf450136bfde77c7f95065c91bffded4aa7fa731. It breaks reboot on at least one Thinkpad T43, as reported by Jörg Otte: "On reboot it shuts down as normal. The last lines displayed are: >Unmounting temporary filesystems.. [OK] >Deactivating swap... [OK] >Unmounting local filesystems... [OK] >Will now restart > Restarting system Then I hear it accessing the cd-drive, but then it's being stuck." Jörg bisected the regression to this commit. That commit fixes another machine (see https://bugzilla.kernel.org/show_bug.cgi?id=11533 for details) that has a BIOS bug and doesn't support ACPI reset. However, at least one of those other reporters no longer even has the machine in question, and had a different workaround to begin with. Besides, it clearly was a buggy BIOS.

2012-04-19xen/xenbus: Add quirk to deal with misconfigured backends.Konrad Rzeszutek Wilk1-16/+53
A rather annoying and common case is when booting a PVonHVM guest and exposing the PV KBD and PV VFB - as broken toolstacks don't always initialize the backends correctly. Normally The HVM guest is using the VGA driver and the emulated keyboard for this (though upstream version of QEMU implements PV KBD, but still uses a VGA driver). We provide a very basic two-stage wait mechanism - where we wait for 30 seconds for all devices, and then for 270 for all them except the two mentioned. That allows us to wait for the essential devices, like network or disk for the full 6 minutes. To trigger this, put this in your guest config: vfb = [ 'vnc=1, vnclisten=0.0.0.0 ,vncunused=1'] instead of this: vnc=1 vnclisten="0.0.0.0" CC: stable@kernel.org Acked-by: Stefano Stabellini <stefano.stabellini@eu.citrix.com> [v3: Split delay in non-essential (30 seconds) and essential devices per Ian and Stefano suggestion] [v4: Added comments per Stefano suggestion] Signed-off-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>

2012-04-19drm: Releasing FBs before releasing GEM objects during drm_releasePrathyush1-3/+3
During DRM release, all the FBs and gem objects are released. If a gem object is being used as a FB and set to a crtc, it must not be freed before releasing the framebuffer first. If FBs are released first, the crtc using the FB is disabled first so now the GEM object can be freed safely. The CRTC will be enabled again when the driver restores fbdev mode.
