2008-04-30ACPI: Fix acpi_processor_idle and idle= boot parameters interactionVenkatesh Pallipadi1-2/+12
acpi_processor_idle and "idle=" boot parameter interaction is broken. The problem is that, at boot time acpi driver is checking for "idle=" boot option and not registering the acpi idle handler. But, when there is a CST changed callback (typically when switching AC <-> battery or suspend-resume) there are no checks for boot_option_idle_override and acpi idle handler tries to get installed with nasty side effects. With CPU_IDLE configured this issue causes results in a nasty oops on CST change callback and without CPU_IDLE there is no oops, but boot option of "idle=" gets ignored and acpi idle handler gets installed. Change the behavior to not do anything in acpi idle handler when there is a "idle=" boot option. Note that the problem is only there when "idle=" boot option is used.

2008-04-30mm: Add NR_WRITEBACK_TEMP counterMiklos Szeredi1-0/+2
Fuse will use temporary buffers to write back dirty data from memory mappings (normal writes are done synchronously). This is needed, because there cannot be any guarantee about the time in which a write will complete. By using temporary buffers, from the MM's point if view the page is written back immediately. If the writeout was due to memory pressure, this effectively migrates data from a full zone to a less full zone. This patch adds a new counter (NR_WRITEBACK_TEMP) for the number of pages used as temporary buffers.

2008-04-30tty/serial: lay the foundations for the next set of reworksAlan Cox26-234/+189
- Stop drivers calling their own flush method indirectly, it obfuscates code and it will change soon anyway - A few more lock_kernel paths temporarily needed in some driver internal waiting code - Remove private put_char method that does a write call for one char - we have that anyway - Most but not yet all of the termios copy under lock fixing (some has other dependencies to follow) - Note a few locking bugs in drivers found in the process - Kill remaining [ab]users of TIOCG/SSOFTCAR in the driver, these must go to fix the termios locking Signed-off-by: Alan Cox <alan@redhat.com> Cc: Jiri Slaby <jirislaby@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2008-04-30drivers/char/ds1286.c: use time_before, time_before_eq, etcJulia Lawall1-1/+2
The functions time_before, time_before_eq, time_after, and time_after_eq are more robust for comparing jiffies against other values. A simplified version of the semantic patch making this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @ change_compare_np @ expression E; @@ ( - jiffies <= E + time_before_eq(jiffies,E) | - jiffies >= E + time_after_eq(jiffies,E) | - jiffies < E + time_before(jiffies,E) | - jiffies > E + time_after(jiffies,E) ) @ include depends on change_compare_np @ @@ #include <linux/jiffies.h> @ no_include depends on !include && change_compare_np @ @@ #include <linux/...> + #include <linux/jiffies.h> // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Cc: Jiri Slaby <jirislaby@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
