With virtual machines like qemu, it's pretty common to see "too much work for irq4" messages nowadays. This happens when a bunch of output is printed on the emulated serial console. This is caused by too low PASS_LIMIT. When ISR loops more than the limit, it spits the message. I've been using a kernel with doubled the limit and I couldn't see no problems. Maybe it's time to get rid of the message now? Signed-off-by: NJiri Slaby <jirislaby@gmail.com> Cc: Alan Cox <alan@linux.intel.com> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

The purpose of the patch is to add EEH support to the 8250_PCI driver for the IBM/Digi PCIE 2port Async EIA-232 Adapter that uses a PLX chipset on the PPC platforrm.

Since commit (4564f9e5: consolidate line discipline number definitions) the patch moved all line discipline number from a per-architecture termios.h to a shared one: tty.h. However, prior to this consolidation work, the line discipline numbers were outside of an ifdef __KERNEL__/endif block so these numbers used to be exported to user-space. Since such numbers are kernel ABI anyway, and tty.h is already included for user- space header processing, just move these relevant defines outside of the ifdef __KERNEL__/endif block in include/linux/tty.h.

Timedia/SUNIX PCI cards with both serial and parallel ports are currently supported by 8250_pci and parport_pc individually. Moving that support into parport_serial allows using both types of ports at the same time. This was successfully tested with a SUNIX 4079T.

Add I/O based support for serial and parallel ports of the following chips: Vendor: Moschip (0x9710) Parts (device IDs) * 9900 (0x9900) * 9904 (0x9904 * 9901 (0x9912, also sold as 9912) * 9922 (0x9922) On all chips but the 9900, a single port is provided per PCI subdevice (subvendor-ID 0xA000, subdevice-IDs 0x1000 for serial, 0x2000 for parallel with proper class codes). In cascading configurations, the 9900 provides two devices per subdevice, with subvendor-ID 0xA000 and subdevice-IDs 0x30ps where p is the number of parallel ports and s the number of serial ports. Basic testing was only done on the serial part of a 9912 to the point where it can be used for a serial kernel console, and advanced features are completely untested. It is possible to reduce functionality of the chips by adding a configuration EEPROM, and the datasheet [1] is inconsistent w.r.t subdevices in the 4s+2s1p and 2s1p+4s configurations. The subdevice-ID 0x3012 should likely read 0x3011 with a serial port in function 3, which would be consistent with the BAR layouts. For now, the drivers ignore subdevices with ID 0x1000 and no class code. The parallel ports are integrated in parport_serial even for purely parallel parts to reduce the footprint of the patch.

Currently, both the WM8903 and TPS6586x chips attempt to register with gpiolib using the same GPIO numbers. This causes the audio driver to fail to initialize. To solve this, add a define to board-harmony.h for the TPS6586x, and make board-harmony-power.c use this define, instead of directly referencing TEGRA_NR_GPIOS.

With xfstest 254 I can panic the box every time with the inode number caching stuff on. This is because we clean the inodes out when we delete the subvolume, but then we write out the inode cache which adds an inode to the subvolume inode tree, and then when it gets evicted again the root gets added back on the dead roots list and is deleted again, so we have a double free. To stop this from happening just return 0 if refs is 0 (and we're not the tree root since tree root always has refs of 0). With this fix 254 no longer panics.

The current scrub implementation reuses bios and pages as often as possible, allocating them only on start and releasing them when finished.

This reverts commit b1c43f82. It was broken in so many ways, and results in random odd pty issues. It re-introduced the buggy schedule_work() in flush_to_ldisc() that can cause endless work-loops (see commit a5660b41: "tty: fix endless work loop when the buffer fills up"). It also used an "unsigned int" return value fo the ->receive_buf() function, but then made multiple functions return a negative error code, and didn't actually check for the error in the caller. And it didn't actually work at all. BenH bisected down odd tty behavior to it: "It looks like the patch is causing some major malfunctions of the X server for me, possibly related to PTYs. For example, cat'ing a large file in a gnome terminal hangs the kernel for -minutes- in a loop of what looks like flush_to_ldisc/workqueue code, (some ftrace data in the quoted bits further down). ... Some more data: It -looks- like what happens is that the flush_to_ldisc work queue entry constantly re-queues itself (because the PTY is full ?) and the workqueue thread will basically loop forver calling it without ever scheduling, thus starving the consumer process that could have emptied the PTY." which is pretty much exactly the problem we fixed in a5660b41. Milton Miller pointed out the 'unsigned int' issue.
