Add IDE_HFLAG_FORCE_LEGACY_IRQS host flag to tell ide_pci_setup_ports() to always set hwif->irq to legacy IRQ 14/15 and convert generic IDE PCI and via82cxxx host drivers to use it. While at it: * Add IDE_HFLAGS_UMC define (generic IDE PCI host driver). * Remove no longer needed init_hwif_generic() (generic IDE PCI host driver). * Set d->udma_mask instead of hwif->ultra_mask (via82cxxx host driver).

Add ->chipset field to ide_pci_device_t and use it in ide_hwif_configure() to set hwif->chipset. Convert cmd64x, cy82c693, rz1000 and trm290 host drivers to use this new ability. While at it define hwif_chipset_t as u8 to save some space in hw_regs_t, ide_hwif_t and ide_pci_device_t instances. Signed-off-by: -

The marker activation functions sits in kernel/marker.c. A hash table is used to keep track of the registered probes and armed markers, so the markers within a newly loaded module that should be active can be activated at module load time. marker_query has been removed. marker_get_first, marker_get_next and marker_release should be used as iterators on the markers.

Quoting Randy: "It seems sad that this patch sources Kconfig.marker, a 7-line file, 20-something times. Yes, you (we) don't want to put those 7 lines into 20-something different files, so sourcing is the right thing. However, what you did for avr32 seems more on the right track to me: make _one_ Instrumentation support menu that includes PROFILING, OPROFILE, KPROBES, and MARKERS and then use (source) that in all of the arches."

Prior to use struct marker in the linux kernel markers, we need to clean two drivers which use this structure name. Change bonding driver types : - struct marker to struct bond_marker. - marker_t to bond_marker_t. - marker_header to bond_marker_header. - marker_header_t to bond_marker_header_t. Change qla4xxx struct marker_entry usage : - Change struct marker_entry for struct qla4_marker_entry. Signed-off-by:

Bernhard Walle authored
This patch adapts IA64 to use the generic parse_crashkernel() function instead of its own parsing for the crashkernel command line. Because the total amount of System RAM must be known when calling this function, efi_memmap_init() is modified to return its accumulated total_memory variable. Also, the crashkernel handling is moved in an own function in arch/ia64/kernel/setup.c to make the code more readable. [kamalesh@linux.vnet.ibm.com: build fix] Signed-off-by:

This patch adds a extended crashkernel syntax that makes the value of reserved system RAM dependent on the system RAM itself: crashkernel=<range1>:<size1>[,<range2>:<size2>,...][@offset] range=start-[end] For example: crashkernel=512M-2G:64M,2G-:128M The motivation comes from distributors that configure their crashkernel command line automatically with some configuration tool (YaST, you know ;)). Of course that tool knows the value of System RAM, but if the user removes RAM, then the system becomes unbootable or at least unusable and error handling is very difficult. This series implements this change for i386, x86_64, ia64, ppc64 and sh. That should be all platforms that support kdump in current mainline. I tested all platforms except sh due to the lack of a sh processor. This patch: This is the generic part of the patch. It adds a parse_crashkernel() function in kernel/kexec.c that is called by the architecture specific code that actually reserves the memory. That function takes the whole command line and looks itself for "crashkernel=" in it. If there are multiple occurrences, then the last one is taken. The advantage is that if you have a bootloader like lilo or elilo which allows you to append a command line parameter but not to remove one (like in GRUB), then you can add another crashkernel value for testing at the boot command line and this one overwrites the command line in the configuration then.

With the use of idr to store the ipc, the case where the idr cache is empty, when idr_get_new is called (this may happen even if we call idr_pre_get() before), is not well handled: it lets semget()/shmget()/msgget() return ENOSPC when this cache is empty, what 1. does not reflect the facts and 2. does not conform to the man(s). This patch fixes this by retrying the whole process of allocation in this case. Signed-off-by:

Some comments about sem_undo_list seem wrong. About the comment above unlock_semundo: "... If task2 now exits before task1 releases the lock (by calling unlock_semundo()), then task1 will never call spin_unlock(). ..." This is just wrong, I see no reason for which task1 will not call spin_unlock... The rest of this comment is also wrong... Unless I miss something (of course). Finally, (un)lock_semundo functions are useless, so remove them for simplification. (this avoids an useless if statement) Signed-off-by:

This is a patch that fixes the way idr_find() used to be called in ipc_lock(): in all the paths that don't imply an update of the ipcs idr, it was called without the idr tree being locked. The changes are: . in ipc_ids, the mutex has been changed into a reader/writer semaphore. . ipc_lock() now takes the mutex as a reader during the idr_find(). . a new routine ipc_lock_down() has been defined: it doesn't take the mutex, assuming that it is being held by the caller. This is the routine that is now called in all the update paths. Signed-off-by:Jarek Poplawski <jarkao2@o2.pl> Signed-off-by:
