2010-09-29spi/amba-pl022: Fix error case return statement.Julia Lawall
The return -EINVAL appears to only make sense if the if branch that it is aligned with is taken, and the indentation indicates that this is the authors intent, so move it into that branch.

2010-09-29mfd: Fix max8925 irq control bit incorrect settingKevin Liu
In max8925_irq_sync_unlock(), irq control bit is set at the same time. Zero means enabling irq, and one means disabling irq. The original code is: irq_chg[0] &= irq_data->enable; It should be changed to: irq_chg[0] &= ~irq_data->enable; Otherwise, irq control bit is mess.

Fixes kernel Bugzilla Bug 18952 This patch adds a syn_set parameter to the retransmits_timed_out() routine and updates its callers. If not set, TCP_RTO_MIN is taken as the calculation basis as before.

Section 4.7.3.1.1 (PM1 Status Registers) of version 4.0 of the ACPI spec concerning PCIEXP_WAKE_STS points out in in the final note field in table 4-11 that if this bit is set to 1 and the system is put into a sleeping state then the system will not automatically wake. This bit gets set by hardware to indicate that the system woke up due to a PCI Express wakeup event, so clear it during acpi_hw_clear_acpi_status() calls to enable subsequent resumes to work.

2010-09-28ALSA: prevent heap corruption in snd_ctl_new()Dan Rosenberg
The snd_ctl_new() function in sound/core/control.c allocates space for a snd_kcontrol struct by performing arithmetic operations on a user-provided size without checking for integer overflow. If a user provides a large enough size, an overflow will occur, the allocated chunk will be too small, and a second user-influenced value will be written repeatedly past the bounds of this chunk. This code is reachable by unprivileged users who have permission to open a /dev/snd/controlC* device (on many distros, this is group "audio") via the SNDRV_CTL_IOCTL_ELEM_ADD and SNDRV_CTL_IOCTL_ELEM_REPLACE ioctls.

2010-09-28iwl3945: queue the right work if the scan needs to be abortedFlorian Mickler
iwl3945's scan_completed calls into the mac80211 stack which triggers a warn on if there is no scan outstanding. This can be avoided by not calling scan_completed but abort_scan in iwl3945_request_scan in the done: branch of the function which is used as an error out. The done: branch seems to be an error-out branch, as, for example, if iwl_is_ready(priv) returns false the done: branch is executed. NOTE: I'm not familiar with the driver at all. I just quickly scanned as a reaction to https://bugzilla.kernel.org/show_bug.cgi?id=17722 the users of scan_completed in the iwl3945 driver and noted the odd discrepancy between the comment above this instance and the comment in mac80211 scan_completed function.

2010-09-28ahci: fix module refcount breakage introduced by libahci splitTejun Heo
libata depends on scsi_host_template for module reference counting and sht's should be owned by each low level driver. During libahci split, the sht was left with libahci.ko leaving the actual low level drivers not reference counted. This made ahci and ahci_platform always unloadable even while they're being actively used. Fix it by defining AHCI_SHT() macro in ahci.h and defining a sht for each low level ahci driver. stable: only applicable to 2.6.35.

Commit e40cc4bdfd4b89813f072f72bd9c7055814d3f0f introduced a build breakage if CONFIG_SMP is undefined. This commit fixes the problem. This fix is only a workaround. For a real fix, cpu_sibling_mask() should be defined in UP include code, eg in linux/smp.h, and asm/smp.h should not be included directly. This fix is currently not possible because asm/smp.h defines cpu_sibling_mask() unconditionally and is included directly from many source files.

Fixes kernel bugzilla #16603 tcp_sendmsg() truncates iov_len to an 'int' which a 4GB write to write zero bytes, for example. There is also the problem higher up of how verify_iovec() works. It wants to prevent the total length from looking like an error return value. However it does this using 'int', but syscalls return 'long' (and thus signed 64-bit on 64-bit machines). So it could trigger false-positives on 64-bit as written. So fix it to use 'long'.
