2008-02-08CONFIG_HIGHPTE vs. sub-page page tables.Martin Schwidefsky
Background: I've implemented 1K/2K page tables for s390. These sub-page page tables are required to properly support the s390 virtualization instruction with KVM. The SIE instruction requires that the page tables have 256 page table entries (pte) followed by 256 page status table entries (pgste). The pgstes are only required if the process is using the SIE instruction. The pgstes are updated by the hardware and by the hypervisor for a number of reasons, one of them is dirty and reference bit tracking. To avoid wasting memory the standard pte table allocation should return 1K/2K (31/64 bit) and 2K/4K if the process is using SIE. Problem: Page size on s390 is 4K, page table size is 1K or 2K. That means the s390 version for pte_alloc_one cannot return a pointer to a struct page. Trouble is that with the CONFIG_HIGHPTE feature on x86 pte_alloc_one cannot return a pointer to a pte either, since that would require more than 32 bit for the return value of pte_alloc_one (and the pte * would not be accessible since its not kmapped). Solution: The only solution I found to this dilemma is a new typedef: a pgtable_t. For s390 pgtable_t will be a (pte *) - to be introduced with a later patch. For everybody else it will be a (struct page *). The additional problem with the initialization of the ptl lock and the NR_PAGETABLE accounting is solved with a constructor pgtable_page_ctor and a destructor pgtable_page_dtor. The page table allocation and free functions need to call these two whenever a page table page is allocated or freed. pmd_populate will get a pgtable_t instead of a struct page pointer. To get the pgtable_t back from a pmd entry that has been installed with pmd_populate a new function pmd_pgtable is added. It replaces the pmd_page call in free_pte_range and apply_to_pte_range.

2008-02-08aout: suppress A.OUT library support if !CONFIG_ARCH_SUPPORTS_AOUTDavid Howells
Suppress A.OUT library support if CONFIG_ARCH_SUPPORTS_AOUT is not set. Not all architectures support the A.OUT binfmt, so the ELF binfmt should not be permitted to go looking for A.OUT libraries to load in such a case. Not only that, but under such conditions A.OUT core dumps are not produced either. To make this work, this patch also does the following: (1) Makes the existence of the contents of linux/a.out.h contingent on CONFIG_ARCH_SUPPORTS_AOUT. (2) Renames dump_thread() to aout_dump_thread() as it's only called by A.OUT core dumping code. (3) Moves aout_dump_thread() into asm/a.out-core.h and makes it inline. This is then included only where needed. This means that this bit of arch code will be stored in the appropriate A.OUT binfmt module rather than the core kernel. (4) Drops A.OUT support for Blackfin (according to Mike Frysinger it's not needed) and FRV. This patch depends on the previous patch to move STACK_TOP[_MAX] out of asm/a.out.h and into asm/processor.h as they're required whether or not A.OUT format is available.

2008-02-07Sanitize the type of struct user.u_ar0H. Peter Anvin
struct user.u_ar0 is defined to contain a pointer offset on all architectures in which it is defined (all architectures which define an a.out format except SPARC.) However, it has a pointer type in the headers, which is pointless -- <asm/user.h> is not exported to userspace, and it just makes the code messy. Redefine the field as "unsigned long" (which is the same size as a pointer on all Linux architectures) and change the setting code to user offsetof() instead of hand-coded arithmetic.

The two S3C SPI master drivers got merged without much review, so I just noticed that they're doing something that the SPI core code is responsible for, rather than any adapter driver: they try to register SPI devices. This removes that support from those drivers so they act normally. Interestingly, none of the current boards are affected. So it's a net code shrink with no loss of functionality.

Currently, the atags used by kexec are fixed to the ones originally used to boot the kernel. This is less than ideal as changing the commandline, initrd and other options would be a useful feature. This patch exports the atags used for the current kernel to userspace through an "atags" file in procfs. The presence of the file is controlled by its own Kconfig option and cleans up several ifdef blocks into a separate file. The tags for the new kernel are assumed to be at a fixed location before the kernel image itself. The location of the tags used to boot the original kernel is unimportant and no longer saved.

Currently early kernel messages, i.e., those from uncompression, go to the debugging UART. And if it is enabled in the platform configuration, but not initialized by the bootloader, the machine hangs, waiting for UART status change. Besides, having those messages on another UART - typically the console UART - may be preferrable. This patch allows selecting the UART in kernel configuration.

* Remove the superfluous declaration of ctrl_alt_del(). * Convert GPIO and IRQ handling to use the <asm/gpio.h> api. * Perform the reset on the release of the power button, so that NAS devices which have been set to auto-power-on (by solder bridging the power button) do not continuously power cycle. * Remove all superflous constants from dsmg600.h Signed-off-by: Rod Whitby <rod@whitby.id.au> Acked-by: Lennert Buytenhek <buytenh@wantstofly.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-02-04[ARM] 4768/2: ixp4xx: Button and LED updates for the nas100d boardRod Whitby
* Convert GPIO and IRQ handling to use the <asm/gpio.h> api. * Perform the reset only after the power button has been held down for at least two seconds. Do the reset on the release of the power button, so that NAS devices which have been set to auto-power-on (by solder bridging the power button) do not continuously power cycle. * Remove all superflous constants from nas100d.h * Add LED constants to nas100d.h while we're there. * Update the board LED setup code to use those constants.

Add include of <linux/bitops.h> to io.h to solve compilations errors in files such as drivers/w1/w1_io.c caused by the ixp4xx version of io.h using the BIT() macro without including <linux/bitops.h> first.

2008-02-01USB: at91_udc uses generic GPIO calls; minor cleanupDavid Brownell
Various small at91_udc cleanups: - Use generic GPIO calls, not older platform-specific ones - Use gpio_request()/gpio_free() - Use VERBOSE_DEBUG convention, not older VERBOSE - Fix sparse complaint about parameter type (changed to gfp_t) - Add missing newline to some rarely-seen debug messages - Fix some old cleanup bugs on probe() fault paths Also add a mechanism whereby rm9200 gpios can drive the D+ pullup through an inverting transistor, based on a patch from Steve Birtles. Most UDC drivers supporting a GPIO based pullup should probably have such an option, but testing it requries such a board in hand!

2008-02-01USB: gadget: pxa2xx_udc supports inverted vbusDmitry Baryshkov
Some boards (like e.g. Tosa) invert the VBUS-detection signal: it's low when a host is supplying VBUS, and high otherwise. Allow specifying whether gpio_vbus value is inverted.

2008-01-31[NET]: Introducing socket mark socket option.Laszlo Attila Toth
A userspace program may wish to set the mark for each packets its send without using the netfilter MARK target. Changing the mark can be used for mark based routing without netfilter or for packet filtering. It requires CAP_NET_ADMIN capability.

2008-01-31[ALSA] Remove sound/driver.hTakashi Iwai
This header file exists only for some hacks to adapt alsa-driver tree. It's useless for building in the kernel. Let's move a few lines in it to sound/core.h and remove it. With this patch, sound/driver.h isn't removed but has just a single compile warning to include it. This should be really killed in future.

2008-01-31Input: pxa27x_keypad - add debounce_interval to the keypad platform dataEric Miao
Currently, only one debounce_interval is introduced for both direct and matrix keys. This is true in most cases, although the keypad controller supports different debounce for direct/matrix keys. Some platforms do require this to be tuned, instead of the default reset value of 100ms. Rotary encoder will always use zero debounce time for now to achieve certain sensitivity.

2008-01-31Input: pxa27x_keypad - enable rotary encoders and direct keysEric Miao
1. Rotary encoder events can be configured either as relative events as the legacy code does or as any specified key code, this is useful on some platform which uses the rotary keys as KEY_{UP/DOWN/LEFT/RIGHT} 2. Add support for direct keys, the corresponding keycodes for each direct key can now be specified within the platform data 3. Remove the direct/rotary key detection code from the IRQ handler to dedicated functions to improve readability Signed-off-by: Eric Miao <eric.miao@marvell.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2008-01-31Input: pxa27x_keypad - introduce pxa27x_keypad_config()Eric Miao
Introduce pxa27x_keypad_config() for keypad registers configuration and remove the reg_kpc, reg_kprec from platform data structure so that configurations of keypad registers can be centralized to a single function. It can also be re-used when resuming. Signed-off-by: Eric Miao <eric.miao@marvell.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2008-01-31Input: pxa27x_keypad - introduce driver structure and use KEY() to define ↵Eric Miao
matrix keys 1. Introduce the "struct pxa27x_keypad" structure for driver specific information, such as "struct clk", generated matrix key codes and so on 2. Use KEY() macro to define matrix keys, instead of original 8x8 map this makes definition easier with keypad where keys are sparse 3. Keep a generated array in "struct pxa27x_keypad" for fast lookup 4. Separate the matrix scan into a dedicated function for readability and report only those keys whose state has been changed, instead of report all states 5. Make use of KPAS to decide the faster path if only one key has been detected Signed-off-by: Eric Miao <eric.miao@marvell.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2008-01-31Input: pxa27x_keypad - remove pin configuration from the driverEric Miao
The pin configurations will slowly be moved to the board specific code at initialization thus to make the driver more generic. Signed-off-by: Eric Miao <eric.miao@marvell.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2008-01-31Input: pxa27x_keypad - rename the driver (was pxa27x_keyboard)Eric Miao
The controller should really be called keypad, and also align the naming of functions and structures to use "pxa27x_keypad" as prefix, instead of "pxakbd". Signed-off-by: Eric Miao <eric.miao@marvell.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
