2005-09-05[PATCH] swap: swap extent list is orderedHugh Dickins
There are several comments that swap's extent_list.prev points to the lowest extent: that's not so, it's extent_list.next which points to it, as you'd expect. And a couple of loops in add_swap_extent which go all the way through the list, when they should just add to the other end. Fix those up, and let map_swap_page search the list forwards: profiles shows it to be twice as quick that way - because prefetch works better on how the structs are typically kmalloc'ed? or because usually more is written to than read from swap, and swap is allocated ascendingly?

2005-09-05[PATCH] mm: consolidate get_orderStephen Rothwell
Someone mentioned that almost all the architectures used basically the same implementation of get_order. This patch consolidates them into asm-generic/page.h and includes that in the appropriate places. The exceptions are ia64 and ppc which have their own (presumably optimised) versions.

2005-09-05[PATCH] sparsemem extreme: hotplug preparationDave Hansen
This splits up sparse_index_alloc() into two pieces. This is needed because we'll allocate the memory for the second level in a different place from where we actually consume it to keep the allocation from happening underneath a lock Signed-off-by: Dave Hansen <haveblue@us.ibm.com> Signed-off-by: Bob Picco <bob.picco@hp.com> Cc: Andy Whitcroft <apw@shadowen.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-09-05[PATCH] sparsemem extreme implementationBob Picco
With cleanups from Dave Hansen <haveblue@us.ibm.com> SPARSEMEM_EXTREME makes mem_section a one dimensional array of pointers to mem_sections. This two level layout scheme is able to achieve smaller memory requirements for SPARSEMEM with the tradeoff of an additional shift and load when fetching the memory section. The current SPARSEMEM implementation is a one dimensional array of mem_sections which is the default SPARSEMEM configuration. The patch attempts isolates the implementation details of the physical layout of the sparsemem section array. SPARSEMEM_EXTREME requires bootmem to be functioning at the time of memory_present() calls. This is not always feasible, so architectures which do not need it may allocate everything statically by using SPARSEMEM_STATIC.

2005-09-05[PATCH] SPARSEMEM EXTREMEBob Picco
A new option for SPARSEMEM is ARCH_SPARSEMEM_EXTREME. Architecture platforms with a very sparse physical address space would likely want to select this option. For those architecture platforms that don't select the option, the code generated is equivalent to SPARSEMEM currently in -mm. I'll be posting a patch on ia64 ml which uses this new SPARSEMEM feature. ARCH_SPARSEMEM_EXTREME makes mem_section a one dimensional array of pointers to mem_sections. This two level layout scheme is able to achieve smaller memory requirements for SPARSEMEM with the tradeoff of an additional shift and load when fetching the memory section. The current SPARSEMEM -mm implementation is a one dimensional array of mem_sections which is the default SPARSEMEM configuration. The patch attempts isolates the implementation details of the physical layout of the sparsemem section array. ARCH_SPARSEMEM_EXTREME depends on 64BIT and is by default boolean false. I've boot tested under aim load ia64 configured for ARCH_SPARSEMEM_EXTREME. I've also boot tested a 4 way Opteron machine with !ARCH_SPARSEMEM_EXTREME and tested with aim.

2005-09-01[ARM] 2865/2: fix fadvise64_64 syscall argument passingNicolas Pitre
Patch from Nicolas Pitre The prototype for sys_fadvise64_64() is: long sys_fadvise64_64(int fd, loff_t offset, loff_t len, int advice) The argument list is therefore as follows on legacy ABI: fd: type int (r0) offset: type long long (r1-r2) len: type long long (r3-sp[0]) advice: type int (sp[4]) With EABI this becomes: fd: type int (r0) offset: type long long (r2-r3) len: type long long (sp[0]-sp[4]) advice: type int (sp[8]) Not only do we have ABI differences here, but the EABI version requires one additional word on the syscall stack. To avoid the ABI mismatch and the extra stack space required with EABI this syscall is now defined with a different argument ordering on ARM as follows: long sys_arm_fadvise64_64(int fd, int advice, loff_t offset, loff_t len) This gives us the following ABI independent argument distribution: fd: type int (r0) advice: type int (r1) offset: type long long (r2-r3) len: type long long (sp[0]-sp[4]) Now, since the syscall entry code takes care of 5 registers only by default including the store of r4 to the stack, we need a wrapper to store r5 to the stack as well. Because that wrapper was missing and was always required this means that sys_fadvise64_64 never worked on ARM and therefore we can safely reuse its syscall number for our new sys_arm_fadvise64_64 interface.

2005-08-31[SERIAL] Clean up and fix tty transmission start/stopingRussell King
The start_tx and stop_tx methods were passed a flag to indicate whether the start/stop was from the tty start/stop callbacks, and some drivers used this flag to decide whether to ask the UART to immediately stop transmission (where the UART supports such a feature.) There are other cases when we wish this to occur - when CTS is lowered, or if we change from soft to hard flow control and CTS is inactive. In these cases, this flag was false, and we would allow the transmitter to drain before stopping. There is really only one case where we want to let the transmitter drain before disabling, and that's when we run out of characters to send. Hence, re-jig the start_tx and stop_tx methods to eliminate this flag, and introduce new functions for the special "disable and allow transmitter to drain" case.

2005-08-30[ALSA] AC97 bus interface for ad-hoc driversLiam Girdwood
AC97 Codec,PCI drivers I've made the review changes and as requested I've pasted the RFC by Nicolas below:- 'I would like to know what people think of the following patch. It allows for a codec on an AC97 bus to be shared with other drivers which are completely unrelated to audio. It registers a new bus type, and whenever a codec instance is created then a device for it is also registered with the driver model using that bus type. This allows, for example, to use the extra features of the UCB1400 like the touchscreen interface and the additional GPIOs and ADCs available on that chip for battery monitoring. I have a working UCB1400 touchscreen driver here that simply registers with the driver model happily working alongside with audio features using this.' Changes over RFC:- o Now matches codec name within codec group. o Added ac97_dev_release() to stop kernel complaining about no release method for device. o Added 'config SND_AC97_BUS' to sound/pci/Kconfig and moved 'config SND_AC97_CODEC' out with the PCI=n statement. o module is now called snd-ac97-bus Signed-off-by: Liam Girdwood <liam.girdwood@wolfsonmicro.com> Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>
