When it detects a truncated report, hid-core emits a warning and then processes the report as usual. This is good because it allows buggy devices to still get data thru to userspace. However, the missing bytes of the report should be cleared before processing, otherwise userspace will be handed partially-uninitialized data. This fixes Debian tracker bug #330487. Signed-off-by:

I haven't been very actively maintaining the input layer in past months, mostly because of my lack of time to concentrate on that. For that reason, I've decided to pass the maintainership of the Linux Input Layer to Dmitry Torokhov, whom I trust to do the job very well. Signed-off-by:

Fix the following bugs in tg3_set_power_state(): 1. Both WOL and ASF flags require switching to aux power. 2. Add a missing handshake with firmware to enable WOL. 3. Turn off the PHY if both WOL and ASF are disabled. 4. Add nvram arbitration before halting the firmware. 5. Fix tg3_setup_copper_phy() to switch to 100Mbps when changing to low power state. Update revision and date. Signed-off-by:

If the dual-port 5704 is configured as a single-port device with only one PCI function, it would trigger a BUG() condition in tg3_find_5704_peer(). This fixes the problem by returning its own pdev if the peer cannot be found. Signed-off-by:

Fix tg3_suspend() and tg3_resume() by clearing and setting the TG3_FLAG_INIT_COMPLETE flag when appropriate. tg3_set_power_state() looks at TG3_FLAG_INIT_COMPLETE on the peer device to determine when to appropriately switch to aux power. Signed-off-by:

The nvram arbitration rules were not strictly followed in a few places and this could lead to reading corrupted values from the nvram. Signed-off-by:

Let's put my money where my mouth is. Smaller code is almost always faster, if only because a single I$ miss ends up leaving a lot of cycles to make up for. And system software - kernels in particular - are known for taking more cache misses than most other kinds. On my random config, this made the kernel about 10% smaller, and lmbench seems to say that it's pretty uniformly faster too. Your milage may vary. Signed-off-by: -

ERR_SEVERITY item is defined as a 8 bits item in SAL documentation ($B.2.1 rev december 2003), but as an u16 in sal.h. This has the side effect that current code in mca.c may not call ia64_sal_clear_state_info() upon receiving corrected platform errors if there are bits set in the validation byte.

KOBJECT_UEVENT=n seems to be a common pitfall for udev users in 2.6.14 . -mm already contains a bigger patch removing this option that is IMHO too big for being applied now to 2.6.15-rc. This patch simply allows KOBJECT_UEVENT=n only if EMBEDDED. Signed-off-by:

Some hardware does not support the PACKET command at all. Other hardware supports ATAPI, but the driver does something nasty such as calling BUG() when an ATAPI command is issued. For these such cases, we mark them with a new flag, ATA_FLAG_NO_ATAPI. Initial version contributed by Ben Collins.

The drawing function cfbfillrect does not work correctly when access is not unsigned-long aligned. It manifests as extra lines of pixels that are not complete drawn. Reversing the shift operator solves the problem, so I would presume that this bug would manifest only on little endian machines. The function cfbcopyarea may also have this bug. Aligned access should present no problems. Signed-off-by:

In slow imageblit, the pixel value is shifted by a certain amount (dependent on the bpp and endianness) for each iteration. This is inefficient. Better do the shifting once before going into the loop. Signed-off-by:

Every framebuffer driver relies on the assumption that the set_par() function of the driver is called before drawing functions and other functions dependent on the hardware state are executed. Whenever you switch from X to a framebuffer console for the very first time, there is a chance that a broken X system has _not_ set the mode to KD_GRAPHICS, thus the vt and framebuffer code executes a screen redraw and several other functions before a set_par() is executed. This is believed to be not a bug of linux but a bug of X/xdm. At least some X releases used by SuSE and Debian show this behaviour. There was a 2nd case, but that has been fixed by Antonino Daplas on 10-dec-2005. This patch allows drivers to set a flag to inform fbcon_switch() that they prefer a set_par() call on every console switch, working around the problems caused by the broken X releases. The flag will be used by the next release of cyblafb and might help other drivers that assume a hardware state different to the one used by X. As the default behaviour does not change, this patch should be acceptable to everybody. Signed-off-by:

Add hooks to save and restore the graphics state. These hooks are called in fbcon_blank() when entering/leaving KD_GRAPHICS mode. This is needed by savagefb at least so it can cooperate with savage_dri and by cyblafb. State save/restoration can be full or partial. Signed-off-by:

There is a bug in the complement_mask when you have a 512-character map. Linux boots to a default 256-character map and most probably your login profile is loading a 512-character map which results in a bad gpm cursor. Signed-off-by:

As reported by Keith Mannthey, there are problems in populate_memnodemap() The bug was that the compute_hash_shift() was returning 31, with incorrect initialization of memnodemap[] To correct the bug, we must use (1UL << shift) instead of (1 << shift) to avoid an integer overflow, and we must check that shift < 64 to avoid an infinite loop.

On systems that do not support the HPET legacy functions (basically the IBM x460, but there could be others), in time_init() we accidentally fall into a PM timer conditional and set the vxtime_hz value to the PM timer's frequency. We then use this value with the HPET for timekeeping. This patch (which mimics the behavior in time_init_gtod) corrects the collision. Signed-off-by:

They report all busses as MMCONFIG capable, but it never works for the internal devices in the CPU's builtin northbridge. It just probes all func 0 devices on bus 0 (the internal northbridge is currently always on bus 0) and if they are not accessible using MCFG they are put into a special fallback bitmap. On systems where it isn't we assume the BIOS vendor supplied correct MCFG. Requires the earlier patch for mmconfig type1 fallback Signed-off-by:

When there is no entry for a bus in MCFG fall back to type1. This is especially important on K8 systems where always some devices can't be accessed using mmconfig (in particular the builtin northbridge doesn't support it for its own devices) Cc: <gregkh@suse.de> Cc: <jgarzik@pobox.com> Signed-off-by:

It's illegal because it can sleep. Use a two step lookup scheme instead. First look up the vm_struct, then change the direct mapping, then finally unmap it. That's ok because nobody can change the particular virtual address range as long as the vm_struct is still in the global list. Also added some LinuxDoc documentation to iounmap. Signed-off-by:
