2007-07-25Cache xtime every call to update_wall_timejohn stultz
This avoids xtime lag seen with dynticks, because while 'xtime' itself is still not updated often, we keep a 'xtime_cache' variable around that contains the approximate real-time that _is_ updated each time we do a 'update_wall_time()', and is thus never off by more than one tick. IOW, this restores the original semantics for 'xtime' users, as long as you use the proper abstraction functions (ie 'current_kernel_time()' or 'get_seconds()' depending on whether you want a timespec or just the seconds field). [ Updated Patch. As penance for my sins I've also yanked another #ifdef that was added to avoid the xtime lag w/ hrtimers. ] Signed-off-by: John Stultz <johnstul@us.ibm.com> Cc: Ingo Molnar <mingo@elte.hu> Cc: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2007-07-25Cleanup non-arch xtime uses, use get_seconds() or current_kernel_time().john stultz
This avoids use of the kernel-internal "xtime" variable directly outside of the actual time-related functions. Instead, use the helper functions that we already have available to us. This doesn't actually change any behaviour, but this will allow us to fix the fact that "xtime" isn't updated very often with CONFIG_NO_HZ (because much of the realtime information is maintained as separate offsets to 'xtime'), which has caused interfaces that use xtime directly to get a time that is out of sync with the real-time clock by up to a third of a second or so.

2007-07-24ata_piix: fix suspend/resume for some TOSHIBA laptopsTejun Heo
ACPI implementations in several TOSHIBA laptops are weird and burn cpu cycles for tens of seconds while trying to suspend if the PCI device for the ATA controller is disabled when the ACPI suspend is called. This patch uses DMI to match those machines and bypass device disable on those machines during suspend. As the device needs to be put into enabled state on resume without affecting PCI enable count, matching resume callback uses __pci_reenable_device(). This bug is reported in bugzilla bug 7780. http://bugzilla.kernel.org/show_bug.cgi?id=7780 Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

2007-07-24Use resource_size_t for serial port IO addressesJosh Boyer
At present, various parts of the serial code use unsigned long to define resource addresses. This is a problem, because some 32-bit platforms have physical addresses larger than 32-bits, and have mmio serial uarts located above the 4GB point. This patch changes the type of mapbase in both struct uart_port and struct plat_serial8250_port to resource_size_t, which can be configured to be 64 bits on such platforms. The mapbase in serial_struct can't safely be changed, because that structure is user visible.

2007-07-22x86: Replace NSC/Cyrix specific chipset access macros by inlined functions.Juergen Beisert
Due to index register access ordering problems, when using macros a line like this fails (and does nothing): setCx86(CX86_CCR2, getCx86(CX86_CCR2) | 0x88); With inlined functions this line will work as expected. Note about a side effect: Seems on Geode GX1 based systems the "suspend on halt power saving feature" was never enabled due to this wrong macro expansion. With inlined functions it will be enabled, but this will stop the TSC when the CPU runs into a HLT instruction.

This patch makes the i386 behave the same way that x86_64 does when a segfault happens. A line gets printed to the kernel log so that tools that need to check for failures can behave more uniformly between debug.show_unhandled_signals sysctl variable to 0 (or by doing echo 0 > /proc/sys/debug/exception-trace) Also, all of the lines being printed are now using printk_ratelimit() to deny the ability of DoS from a local user with a program like the following: main() { while (1) if (!fork()) *(int *)0 = 0; } This new revision also includes the fix that Andrew did which got rid of new sysctl that was added to the system in earlier versions of this. Also, 'show-unhandled-signals' sysctl has been renamed back to the old 'exception-trace' to avoid breakage of people's scripts.

The following git mv commands are needed before this patch can be applied: git mv include/asm-arm/arch-s3c2410/regs-ac97.h include/asm-arm/plat-s3c/regs-ac97.h git mv include/asm-arm/arch-s3c2410/regs-adc.h include/asm-arm/plat-s3c/regs-adc.h git mv include/asm-arm/arch-s3c2410/regs-iis.h include/asm-arm/plat-s3c24xx/regs-iis.h git mv include/asm-arm/arch-s3c2410/regs-spi.h include/asm-arm/plat-s3c24xx/regs-spi.h git mv include/asm-arm/arch-s3c2410/regs-udc.h include/asm-arm/plat-s3c24xx/regs-udc.h git mv include/asm-arm/arch-s3c2410/udc.h include/asm-arm/plat-s3c24xx/udc.h Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
