* [PATCH] i386: pit_latch_buggy has no effecttakada2007-05-022-3/+1
| | | | | | | | | | | | | | Eliminated the arch/i386/kernel/timers in 2.6.18, use clocksoures instead. pit_latch_buggy was referred in timers/timer_tsc.c, and currently removed. Therefore nobody refer it. Until 2.6.17, MediaGX's TSC works correctly. after 2.6.18, warned "TSC appears to be running slowly. Marking it as unstable". So marked unstable TSC when CS55x0.

* [PATCH] x86: consolidate smp_send_stop()Jan Beulich2007-05-022-48/+48
| | | | | | | | | | | | | | | Synchronize i386's smp_send_stop() with x86-64's in only try-locking the call lock to prevent deadlocks when called from panic(). In both version, disable interrupts before clearing the CPU off the online map to eliminate races with IRQ handlers inspecting this map. Also in both versions, save/restore interrupts rather than disabling/ enabling them. On x86-64, eliminate one function used here by folding it into its single caller, convert to static, and rename for consistency with i386 (lkcd may like this).

* [PATCH] i386: adjustments to page table dump during oops (v4)Jan Beulich2007-05-021-20/+35
| | | | | | | | | | | | | | | | | - make the page table contents printing PAE capable - make sure the address stored in current->thread.cr2 is unmodified from what was read from CR2 - don't call oops_may_print() multiple times, when one time suffices - print pte even in highpte case, as long as the pte page isn't in actually in high memory (which is specifically the case for all page tables covering kernel space) (Changes to v3: Use sizeof()*2 rather than the suggested sizeof()*4 for printing width, use fixed 16-nibble width for PAE, and also apply the max_low_pfn range check to the middle level lookup on PAE.)

* [PATCH] x86-64: always use physical delivery mode on > 8 CPUsIngo Molnar2007-05-021-56/+15
| | | | | | | | | | | | | | | | | | | | Remove clustered APIC mode. There's little point in the use of clustered APIC mode, broadcasting is limited to within the cluster only, and chipsets have bugs in this area as well. So default to physical APIC mode when the CPU count is large, and default to logical APIC mode when the CPU count is 8 or smaller. (this patch only removes the use of genapic_cluster and cleans up the resulting genapic.c file - removal of all remaining traces of clustered mode will be done by another patch.)

* [PATCH] x86-64: optimize & fix APIC mode setupIngo Molnar2007-05-021-24/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix a couple of inconsistencies/problems I found while reviewing the x86_64 genapic code (when I was chasing mysterious eth0 timeouts that would only trigger if CPU_HOTPLUG is enabled): - AMD systems defaulted to the slower flat-physical mode instead of the flat-logical mode. The only restriction on AMD systems is that they should not use clustered APIC mode. - removed the CPU hotplug hacks, switching the default for small systems back from phys-flat to logical-flat. The switching to logical flat mode on small systems fixed sporadic ethernet driver timeouts i was getting on a dual-core Athlon64 system: NETDEV WATCHDOG: eth0: transmit timed out eth0: Transmit timeout, status 0c 0005 c07f media 80. eth0: Tx queue start entry 32 dirty entry 28. eth0: Tx descriptor 0 is 0008a04a. (queue head) eth0: Tx descriptor 1 is 0008a04a. eth0: Tx descriptor 2 is 0008a04a. eth0: Tx descriptor 3 is 0008a04a. eth0: link up, 100Mbps, full-duplex, lpa 0xC5E1 - The use of '<= 8' was a bug by itself (the valid APIC ids for logical flat mode go from 0 to 7, not 0 to 8). The new logic is to use logical flat mode on both AMD and Intel systems, and to only switch to physical mode when logical mode cannot be used. If CPU hotplug is racy wrt. APIC shutdown then CPU hotplug needs fixing, not the whole IRQ system be made inconsistent and slowed down. - minor cleanups: simplified some code constructs build & booted on a couple of AMD and Intel SMP systems.

* power management: implement pm_ops.valid for everybodyJohannes Berg2007-04-308-53/+11
| | | | | | | | | | | | | | | | | | | | | | Almost all users of pm_ops only support mem sleep, don't check in .valid and don't reject any others in .prepare so users can be confused if they check /sys/power/state, especially when new states are added (these would then result in s-t-r although they're supposed to be something different). This patch implements a generic pm_valid_only_mem function that is then exported for users and puts it to use in almost all existing pm_ops.

* rework pm_ops pm_disk_mode, kill misuseJohannes Berg2007-04-308-31/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch series cleans up some misconceptions about pm_ops. Some users of the pm_ops structure attempt to use it to stop the user from entering suspend to disk, this, however, is not possible since the user can always use "shutdown" in /sys/power/disk and then the pm_ops are never invoked. Also, platforms that don't support suspend to disk simply should not allow configuring SOFTWARE_SUSPEND (read the help text on it, it only selects suspend to disk and nothing else, all the other stuff depends on PM). The pm_ops structure is actually intended to provide a way to enter platform-defined sleep states (currently supported states are "standby" and "mem" (suspend to ram)) and additionally (if SOFTWARE_SUSPEND is configured) allows a platform to support a platform specific way to enter low-power mode once everything has been saved to disk. This is currently only used by ACPI (S4). This patch: The pm_ops.pm_disk_mode is used in totally bogus ways since nobody really seems to understand what it actually does. This patch clarifies the pm_disk_mode description. It also removes all the arm and sh users that think they can veto suspend to disk via pm_ops; not so since the user can always do echo shutdown > /sys/power/disk, they need to find a better way involving Kconfig or such. ACPI is the only user left with a non-zero pm_disk_mode. The patch also sets the default mode to shutdown again, but when a new pm_ops is registered its pm_disk_mode is selected as default, that way the default stays for ACPI where it is apparently required.

| * | [POWERPC] Generic check_legacy_ioportOlaf Hering2007-04-277-77/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | check_legacy_ioport makes only sense on PREP, CHRP and pSeries. They may have an isa node with PS/2, parport, floppy and serial ports. Remove the check_legacy_ioport call from ppc_md, it's not needed anymore. Hardware capabilities come from the device-tree.

| * | [POWERPC] bootwrapper: cuboot-83xx: Exclude upper 1MB from heap.Scott Wood2007-04-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The uppermost part of memory is where u-boot puts the stack, so don't include that in the heap. It's not currently causing problems, as the current code allocates from the bottom of the heap, but this will keep things from potentially breaking if a future implementation were to allocate from the top.

| * | [POWERPC] bootwrapper: Fix array handling in dt_xlate_reg().Scott Wood2007-04-271-12/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a few bugs in how dt_xlate_reg() handles address arrays: 1. copy_val() was copying into the wrong end of the array, resulting in random stack garbage at the other end. 2. dt_xlate_reg() was getting the result from the wrong end of the array. 3. add_reg() and sub_reg() were treating the arrays as little-endian rather than big-endian. 4. add_reg() only returned an error on a carry out of the entire array, rather than out of the naddr portion. 5. The requested reg resource was checked to see if it exceeded the size of the reg property, but not to see if it exceeded the size of the buffer.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Change the error message in gunzip_exactly to be more verbose. Besides the identifier being unrelated to the current function name, the user had no indication if the corruption was near the beginning or the end.
