SPARSEMEM is a pretty nice framework that unifies quite a bit of code over all the arches. It would be great if it could be the default so that we can get rid of various forms of DISCONTIG and other variations on memory maps. So far what has hindered this are the additional lookups that SPARSEMEM introduces for virt_to_page and page_address. This goes so far that the code to do this has to be kept in a separate function and cannot be used inline. This patch introduces a virtual memmap mode for SPARSEMEM, in which the memmap is mapped into a virtually contigious area, only the active sections are physically backed. This allows virt_to_page page_address and cohorts become simple shift/add operations. No page flag fields, no table lookups, nothing involving memory is required. The two key operations pfn_to_page and page_to_page become: #define __pfn_to_page(pfn) (vmemmap + (pfn)) #define __page_to_pfn(page) ((page) - vmemmap) By having a virtual mapping for the memmap we allow simple access without wasting physical memory. As kernel memory is typically already mapped 1:1 this introduces no additional overhead. The virtual mapping must be big enough to allow a struct page to be allocated and mapped for all valid physical pages. This vill make a virtual memmap difficult to use on 32 bit platforms that support 36 address bits. However, if there is enough virtual space available and the arch already maps its 1-1 kernel space using TLBs (f.e. true of IA64 and x86_64) then this technique makes SPARSEMEM lookups even more efficient than CONFIG_FLATMEM. FLATMEM needs to read the contents of the mem_map variable to get the start of the memmap and then add the offset to the required entry. vmemmap is a constant to which we can simply add the offset. This patch has the potential to allow us to make SPARSMEM the default (and even the only) option for most systems. It should be optimal on UP, SMP and NUMA on most platforms. Then we may even be able to remove the other memory models: FLATMEM, DISCONTIG etc. [apw@shadowen.org: config cleanups, resplit code etc] [kamezawa.hiroyu@jp.fujitsu.com: Fix sparsemem_vmemmap init] [apw@shadowen.org: vmemmap: remove excess debugging] [apw@shadowen.org: simplify initialisation code and reduce duplication] [apw@shadowen.org: pull out the vmemmap code into its own file] Signed-off-by:

We have flags to indicate whether a section actually has a valid mem_map associated with it. This is never set and we rely solely on the present bit to indicate a section is valid. By definition a section is not valid if it has no mem_map and there is a window during init where the present bit is set but there is no mem_map, during which pfn_valid() will return true incorrectly. Use the existing SECTION_HAS_MEM_MAP flag to indicate the presence of a valid mem_map. Switch valid_section{,_nr} and pfn_valid() to this bit. Add a new present_section{,_nr} and pfn_present() interfaces for those users who care to know that a section is going to be valid. [akpm@linux-foundation.org: coding-syle fixes] Signed-off-by: -

Then we may even be able to remove the other memory models: FLATMEM, DISCONTIG etc. The current aim is to bring a common virtually mapped mem_map to all architectures. This should facilitate the removal of the bespoke implementations from the architectures. This also brings performance improvements for most architecture making sparsmem vmemmap the more desirable memory model. The ultimate aim of this work is to expand sparsemem support to encompass all the features of the other memory models. This could allow us to drop support for and remove the other models in the longer term. Below are some comparitive kernbench numbers for various architectures, comparing default memory model against SPARSEMEM VMEMMAP. All but ia64 show marginal improvement; we expect the ia64 figures to be sorted out when the larger mapping support returns. x86-64 non-NUMA Base VMEMAP % change (-ve good) User 85.07 84.84 -0.26 System 34.32 33.84 -1.39 Total 119.38 118.68 -0.59 ia64 Base VMEMAP % change (-ve good) User 1016.41 1016.93 0.05 System 50.83 51.02 0.36 Total 1067.25 1067.95 0.07 x86-64 NUMA Base VMEMAP % change (-ve good) User 30.77 431.73 0.22 System 45.39 43.98 -3.11 Total 476.17 475.71 -0.10 ppc64 Base VMEMAP % change (-ve good) User 488.77 488.35 -0.09 System 56.92 56.37 -0.97 Total 545.69 544.72 -0.18 Below are some AIM bencharks on IA64 and x86-64 (thank Bob).

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.

This is from an earlier message from 'Christoph Lameter': cpu_core_map is currently an array defined using NR_CPUS. This means that we overallocate since we will rarely really use maximum configured cpu. If we put the cpu_core_map into the per cpu area then it will be allocated for each processor as it comes online. This means that the core map cannot be accessed until the per cpu area has been allocated. Xen does a weird thing here looping over all processors and zeroing the masks that are not yet allocated and that will be zeroed when they are allocated. I commented the code out. Signed-off-by: -

Enable wakeup from serial ports, make it run-time configurable over sysfs, e.g., echo enabled > /sys/devices/platform/serial8250.0/tty/ttyS0/power/wakeup Requires # CONFIG_SYSFS_DEPRECATED is not set Following suggestions from Alan and Russell moved the may_wake_up checks to serial_core.c. This time actually tested - it does even work. Could someone, please, verify, that put_device after device_find_child is correct? Also would be nice to test with a Natsemi UART, that can wake up the system, if such systems exist. For this you just have to apply the patch below, issue the above "echo" command to one of your Natsemi port, suspend and resume your system, and verify that your Natsemi port still works. If you are actually capable of waking up the system from that port, would be nice to test that as well. Signed-off-by:

Recently I've been trying to get working PCMCIA interface on H5000 ipaq series, using dual PCMCIA sleeve. So far things work correctly, but I had to do one modification to drivers/pcmcia/pxa2xx_base.c to get the interface working with orinoco gold PCMCIA card (wired pcnet_cs ethernet card worked even without this modification). The issue has something to do with assert time on PCMCIA bus, but I'm not really sure what -- I found the working value just by trial&error approach. I'm not sure how is the assert value in pxa2xx_mcxx_asst calculated (I know, simple formula, but the reason why is it calculated that way is not obvious for me), neither that my modification is correct. It just works with iPAQ. Cc: Russell King <rmk@arm.linux.org.uk> Cc: Richard Purdie <rpurdie@rpsys.net> Cc: Dominik Brodowski <linux@dominikbrodowski.net> Signed-off-by:

Optionally add a boot delay after each kernel printk() call, crudely measured in milliseconds, with a maximum delay of 10 seconds per printk. Enable CONFIG_BOOT_PRINTK_DELAY=y and then add (e.g.): "lpj=loops_per_jiffy boot_delay=100" to the kernel command line. It has been useful in cases like "during boot, my machine just reboots or the screen goes black" by slowing down printk, (and adding initcall_debug), we can usually see the last thing that happened before the lights went out which is usually a valuable clue.

Very little point of having 32-bit snd_cnwd if this is not 32-bit as well, as a number of snd_cwnd incrementation formulas assume that snd_cwnd_cnt can be at least as large as snd_cwnd.
