2007-11-09[IA64] Update printing of feature set bitsRuss Anderson1-2/+3
Newer Itanium versions have added additional processor feature set bits. This patch prints all the implemented feature set bits. Some bit descriptions have not been made public. For those bits, a generic "Feature set X bit Y" message is printed. Bits that are not implemented will no longer be printed.

2007-10-29[IA64] /proc/cpuinfo "physical id" field cleanupsAlex Chiang1-1/+0
Clean up the process for presenting the "physical id" field in /proc/cpuinfo. - remove global smp_num_cpucores, as it is mostly useless - remove check_for_logical_procs(), since we do the same functionality in identify_siblings() - reflow logic in identify_siblings(). If an older CPU does not implement PAL_LOGICAL_TO_PHYSICAL, we may still be able to get useful information from SAL_PHYSICAL_ID_INFO - in identify_siblings(), threads/cores are a property of the CPU, not the platform - remove useless printk's about multi-core / thread capability in identify_siblings(), as that information is readily available in /proc/cpuinfo, and printing for the BSP only adds little value - smp_num_siblings is now meaningful if any CPU in the system supports threads, not just the BSP - expose "physical id" field, even on CPUs that are not multi-core / multi-threaded (as long as we have a valid value). Now we know what sockets Madisons live in too. Signed-off-by: Alex Chiang <achiang@hp.com> Signed-off-by: Tony Luck <tony.luck@intel.com>

2007-10-22Change table chaining layoutJens Axboe1-1/+1
Change the page member of the scatterlist structure to be an unsigned long, and encode more stuff in the lower bits: - Bits 0 and 1 zero: this is a normal sg entry. Next sg entry is located at sg + 1. - Bit 0 set: this is a chain entry, the next real entry is at ->page_link with the two low bits masked off. - Bit 1 set: this is the final entry in the sg entry. sg_next() will return NULL when passed such an entry. It's thus important that sg table users use the proper accessors to get and set the page member. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

2007-10-19Use extended crashkernel command line on ia64Bernhard Walle1-1/+1
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.

2007-10-17Remove dma_cache_(wback|inv|wback_inv) functionsRalf Baechle1-4/+0
dma_cache_(wback|inv|wback_inv) were the earliest attempt on a generalized cache managment API for I/O purposes. Originally it was basically the raw MIPS low level cache API exported to the entire world. The API has suffered from a lack of documentation, was not very widely used unlike it's more modern brothers and can easily be replaced by dma_cache_sync. So remove it rsp. turn the surviving bits back into an arch private API, as discussed on linux-arch.

2007-10-17Add vmcoreinfoKen'ichi Ohmichi1-0/+1
This patch set frees the restriction that makedumpfile users should install a vmlinux file (including the debugging information) into each system. makedumpfile command is the dump filtering feature for kdump. It creates a small dumpfile by filtering unnecessary pages for the analysis. To distinguish unnecessary pages, it needs a vmlinux file including the debugging information. These days, the debugging package becomes a huge file, and it is hard to install it into each system. To solve the problem, kdump developers discussed it at lkml and kexec-ml. As the result, we reached the conclusion that necessary information for dump filtering (called "vmcoreinfo") should be embedded into the first kernel file and it should be accessed through /proc/vmcore during the second kernel. (http://www.uwsg.iu.edu/hypermail/linux/kernel/0707.0/1806.html) Dan Aloni created the patch set for the above implementation. (http://www.uwsg.iu.edu/hypermail/linux/kernel/0707.1/1053.html) And I updated it for multi architectures and memory models.

Introduce architecture dependent kretprobe blacklists to prohibit users from inserting return probes on the function in which kprobes can be inserted but kretprobes can not. This patch also removes "__kprobes" mark from "__switch_to" on x86_64 and registers "__switch_to" to the blacklist on x86-64, because that mark is to prohibit user from inserting only kretprobe.

2007-10-16flush icache before set_pte() on ia64: flush icache at set_pteKAMEZAWA Hiroyuki1-13/+31
Current ia64 kernel flushes icache by lazy_mmu_prot_update() *after* set_pte(). This is too late. This patch removes lazy_mmu_prot_update and add modfied set_pte() for flushing if necessary. This patch flush icache of a page when new pte has exec bit. && new pte has present bit && new pte is user's page. && (old *ptep is not present || new pte's pfn is not same to old *ptep's ptn) && new pte's page has no Pg_arch_1 bit. Pg_arch_1 is set when a page is cache consistent. I think this condition checks are much easier to understand than considering "Where sync_icache_dcache() should be inserted ?". pte_user() for ia64 was removed by http://lkml.org/lkml/2007/6/12/67 as clean-up.

2007-10-16x86: optimize page faults like all other achitectures and kill notifier cruftChristoph Hellwig2-16/+0
x86(-64) are the last architectures still using the page fault notifier cruft for the kprobes page fault hook. This patch converts them to the proper direct calls, and removes the now unused pagefault notifier bits aswell as the cruft in kprobes.c that was related to this mess. I know Andi didn't really like this, but all other architecture maintainers agreed the direct calls are much better and besides the obvious cruft removal a common way of dealing with kprobes across architectures is important aswell.

2007-07-19coredump masking: reimplementation of dumpable using two flagsKawai, Hidehiro1-2/+2
This patch changes mm_struct.dumpable to a pair of bit flags. set_dumpable() converts three-value dumpable to two flags and stores it into lower two bits of mm_struct.flags instead of mm_struct.dumpable. get_dumpable() behaves in the opposite way.

2007-07-19arch: personality independent stack topPeter Zijlstra1-0/+1
New arch macro STACK_TOP_MAX it gives the larges valid stack address for the architecture in question. It differs from STACK_TOP in that it will not distinguish between personalities but will always return the largest possible address. This is used to create the initial stack on execve, which we will move down to the proper location once the binfmt code has figured out where that is.

2007-07-19define new percpu interface for shared dataFenghua Yu1-0/+10
per cpu data section contains two types of data. One set which is exclusively accessed by the local cpu and the other set which is per cpu, but also shared by remote cpus. In the current kernel, these two sets are not clearely separated out. This can potentially cause the same data cacheline shared between the two sets of data, which will result in unnecessary bouncing of the cacheline between cpus. One way to fix the problem is to cacheline align the remotely accessed per cpu data, both at the beginning and at the end. Because of the padding at both ends, this will likely cause some memory wastage and also the interface to achieve this is not clean. This patch: Moves the remotely accessed per cpu data (which is currently marked as ____cacheline_aligned_in_smp) into a different section, where all the data elements are cacheline aligned. And as such, this differentiates the local only data and remotely accessed data cleanly.

2007-07-19jprobes: remove JPROBE_ENTRY()Michael Ellerman1-2/+0
AFAICT now that jprobe.entry is a void *, JPROBE_ENTRY doesn't do anything useful - so remove it .. I've left a do-nothing version so that out-of-tree jprobes code will still compile without modifications.

2007-07-17fbdev: detect primary display deviceAntonino A. Daplas1-0/+6
Add function helper, fb_is_primary_device(). Given struct fb_info, it will return a nonzero value if the device is the primary display. Currently, only the i386 is supported where the function checks for the IORESOURCE_ROM_SHADOW flag.
