2007-12-06[PARISC] print more than one character at a time for pdc consoleKyle McMartin
There's really no reason not to print more than one character at a time to the PDC console... Booting is measurably speedier, and now I don't have to watch individual characters get drawn. Signed-off-by: Kyle McMartin <kyle@mcmartin.ca>
2007-12-06[PARISC] timer interrupt should not be IRQ_DISABLEDKyle McMartin
The timer interrupt had accidentally been marked IRQ_DISABLED since IRQ_PER_CPU had been OR-ed in, instead of set. This had been working by accident for quite a while. Commit c642b8391cf8efc3622cc97329a0f46e7cbb70b8 changed the behaviour of IRQ_PER_CPU interrupts, which previously weren't checked for IRQ_DISABLED. Signed-off-by: Kyle McMartin <kyle@mcmartin.ca>
2007-12-06Revert "[PARISC] import necessary bits of libgcc.a"Kyle McMartin
This reverts commit efb80e7e097d0888e59fbbe4ded2ac5a256f556d, it turned out to cause sporadic problems with the timer interrupt on 32-bit kernels. Needs more investigation. Signed-off-by: Kyle McMartin <kyle@mcmartin.ca>

2007-12-06[POWERPC] Update defconfigsPaul Mackerras
This updates all the defconfigs in arch/powerpc/configs except iseries and ps3, which were updated by the preceding commits. This mostly takes the defaults, except that I turned on tickless idle and high-resolution timers for everything, and turned off instrumentation support and "Fair group CPU scheduler" for the smaller/embedded platforms.

2007-12-06[POWERPC] Fix hardware IRQ time accounting problem.Tony Breeds
The commit fa13a5a1f25f671d084d8884be96fc48d9b68275 (sched: restore deterministic CPU accounting on powerpc), unconditionally calls update_process_tick() in system context. In the deterministic accounting case this is the correct thing to do. However, in the non-deterministic accounting case we need to not do this, since doing this results in the time accounted as hardware irq time being artificially elevated. Also this collapses 2 consecutive '#ifdef CONFIG_VIRT_CPU_ACCOUNTING' checks in time.h into one for neatness.

2007-12-06[POWERPC] Implement 'make bootwrapper_install'David Woodhouse

2007-12-06[POWERPC] Create otheros.bld next to specified output file, not in $object ↵David Woodhouse
directory The bootwrapper script currently generates an 'otheros.bld' file in addition to the file specified by the -o option, when asked to build a wrapper for PS3. It should do that in the same directory as the output, not the directory where the wrapper objects are kept (which might potentially not be writable when the script runs). Arguably, the 'otheros.bld' ought to be created with the filename specified as the -o argument. But that's a more intrusive change.

2007-12-04x86: add the word 'WARNING' in check_nmi_watchdog() outputDon Zickus
Our automated test suite looks for keywords like error, fail, warning in the boot log. In the case when the nmi watchdog is determined to be stuck in check_nmi_watchdog(), none of those keywords are displayed. This patch adds a keyword, "WARNING:", so it makes it easier to notice when the nmi watchdog isn't working correctly. Also add a proper KERN_WARNING mark to this printout.

2007-12-04x86: revert CONFIG_X86_HT semantics changeAdrian Bunk
The recent Kconfig changes in x86 resulted in CONFIG_X86_HT no longer being set if (X86_32 && MK8). After grep'ing through the tree I think the problem is that different places have different assumptions about the semantics of CONFIG_X86_HT, either: - hyperthreading or - multicore This should be sorted out properly, but until then we should keep the 2.6.23 status quo.

2007-12-03x86: disable hpet on shutdownOGAWA Hirofumi
If HPET was enabled by pci quirks, we use i8253 as initial clockevent because pci quirks doesn't run until pci is initialized. The above means the kernel (or something) is assuming HPET legacy replacement is disabled and can use i8253 at boot. If we used kexec, it isn't true. So, this patch disables HPET legacy replacement for kexec in machine_shutdown().

2007-12-03uml: work around host tcsetattr bugJeff Dike
Under the conditions that UML uses it, tcgetattr is guaranteed to return -EINTR when the console is attached to /dev/ptmx, making generic_console_write hang because it loops, calling tcgetattr until it succeeds. This is a host bug - see http://marc.info/?l=linux-kernel&m=119618990807182&w=2 for the details. This patch works around it by blocking SIGIO while the terminal attributes are being fiddled.
