The last things through the 2.6.26 merge window
About 500 changesets were merged after the publication of the
2.6.26 merge window
summaries. The merge window is now closed; here is the final set of
changes which got in:
- New drivers for Solarflare Communications Solarstorm SFC4000
controller-based Ethernet controllers,
Hauppauge HVR-1600 TV tuner cards,
ISP 1760 USB host controllers,
Cypress c67x00 OTG controllers, and
Intel PXA 27x USB controllers.
- 8Kb stacks are, once again, the default for the x86 architecture.
"Out-of-memory situations are less problematic than silent and
hard to debug stack corruption."
- The klist type now has the usual-form macros for declaration and
initialization: DEFINE_KLIST() and KLIST_INIT().
Two new functions (klist_add_after() and
klist_add_before()) can be used to add entries to a klist in
a specific position.
- As had been planned, struct class_device has been removed
from the driver core, along with all of the associated infrastructure.
Classes are now implemented with an ordinary struct device.
- kmap_atomic_to_page() is no longer exported to modules.
- There are some new generic functions for performing 64-bit integer
division in the kernel:
u64 div_u64(u64 dividend, u32 divisor);
u64 div_u64_rem(u64 dividend, u32 divisor, u32 *remainder);
s64 div_s64(s64 dividend, s32 divisor)
s64 div_s64_rem(s64 dividend, s32 divisor, s32 *remainder);
Unlike do_div(), these functions are explicit about whether
signed or unsigned math is being done. The x86-specific
div_long_long_rem() has been removed in favor of these new
- There is a new string function:
bool sysfs_streq(const char *s1, const char *s2);
It compares the two strings while ignoring an optional trailing
- The prototype for i2c probe() methods has changed:
int (*probe)(struct i2c_client *client,
const struct i2c_device_id *id);
The new id argument supports i2c device name aliasing.
- There is a new configuration (MODULE_FORCE_LOAD) which
controls whether the loading of modules can be forced if the kernel
thinks something is not right; it defaults to "no."
