2005-11-01[ARM] 3078/1: lubbock platform updates, mostly mmc detectionDavid Brownell
Patch from David Brownell Lubbock updates: * Provide an address for the SMC91x chip that doesn't generate a boot-time warning (matching the EEPROM). * Update MMC support to (a) detect card insert/remove, and (b) report the readonly switch setting for SD cards. Previously, MMC/SD cards had to be present at boot time else they couldn't be detected.

2005-11-01[ARM] 3064/1: start using ixp2000_reg_wrbLennert Buytenhek
Patch from Lennert Buytenhek Switch the users of ixp2000_reg_write that depend on writes being flushed out of the write buffer by the time that function returns over to ixp2000_reg_wrb. When using XCB=101, writes to the same functional unit are still guaranteed to complete in order, so we only need to protect against: - reordering of writes to different functional units - masking an interrupt and then reenabling the IRQ bit in CPSR Signed-off-by: Lennert Buytenhek <buytenh@wantstofly.org> Signed-off-by: Deepak Saxena <dsaxena@plexity.net> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2005-11-01[ARM] 3063/1: allow slave ixp2000 cpu resetLennert Buytenhek
Patch from Lennert Buytenhek On the ixdp2x00, the slave CPU is currently not allowed to reset itself for fear that it will do something 'funky' on the PCI bus. This fear is ungrounded -- the slave CPU is wired up such that a CPU reset will not cause a PCI bus reset to be done. This patch changes arch_reset() so that the slave CPU also executes the reset sequence, allowing it to reboot itself using /sbin/reboot.

2005-11-01[ARM] 3062/1: map in various enp2611 peripherals for the ixp2000 netdev driverLennert Buytenhek
Patch from Lennert Buytenhek The enp2611 version of the ixp2000 netdev driver needs to be able to access a number of on-board peripherals. ioremap() is not suitable for this, as that will cause XCB=000 mappings to be done, which will make the cpu susceptible to crashing on ixp2400 erratum #66. Properly aligned iotable mappings with MT_IXP2000_DEVICE will cause section mappings with XCB=101 to be done, which is safe.

We had a static memory_limit in prom.c, and then another one defined in setup_64.c and used in numa.c, which resulted in the kernel crashing when mem=xxx was given on the command line.

2005-10-30[PATCH] fix missing includesTim Schmielau
I recently picked up my older work to remove unnecessary #includes of sched.h, starting from a patch by Dave Jones to not include sched.h from module.h. This reduces the number of indirect includes of sched.h by ~300. Another ~400 pointless direct includes can be removed after this disentangling (patch to follow later). However, quite a few indirect includes need to be fixed up for this. In order to feed the patches through -mm with as little disturbance as possible, I've split out the fixes I accumulated up to now (complete for i386 and x86_64, more archs to follow later) and post them before the real patch. This way this large part of the patch is kept simple with only adding #includes, and all hunks are independent of each other. So if any hunk rejects or gets in the way of other patches, just drop it. My scripts will pick it up again in the next round.

2005-10-30[PATCH] hpet-RTC: cache the comparator registerClemens Ladisch
Reads from an HPET register require a round trip to the south bridge and are almost as slow as PCI reads. By caching the last value we've written to the comparator register, we can eliminate all HPET reads from the fast path in the emulated RTC interrupt handler.

2005-10-30[PATCH] hpet-RTC: fix timer config register accessesClemens Ladisch
Make sure that the RTC timer is in non-periodic mode; some stupid BIOS might have initialized it to periodic mode. Furthermore, don't set the SETVAL bit in the config register. This wouldn't have any effect unless the timer was in period mode (which it isn't), and then the actual timer frequency would be half that of the desired one because incrementing the comparator in the interrupt handler would be done after the hardware has already incremented it itself.

2005-10-30[PATCH] hpet-RTC: disable interrupt when no longer neededClemens Ladisch
When the emulated RTC interrupt is no longer needed, we better disable it; otherwise, we get a spurious interrupt whenever the timer has rolled over and reaches the same comparator value. Having a superfluous interrupt every five minutes doesn't hurt much, but it's bad style anyway. ;-) Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Acked-by: "Pallipadi, Venkatesh" <venkatesh.pallipadi@intel.com> Cc: Andi Kleen <ak@muc.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-10-30[PATCH] hpet: allow shared interruptsClemens Ladisch
This patch adds support for shared HPET interrupts. The driver previously acknowledged interrupts for both edge and level interrupts, but didn't actually allow a shared interrupt in the latter case. We use a new per-timer flag to save whether the timer's interrupt might be shared, and use it to do the processing required for level interrupts only if necessary.

2005-10-30[PATCH] HPET: make frequency calculations 32 bit safeClemens Ladisch
On 32-bit architectures, the multiplication in the argument for hpet_time_div() often overflows. In the typical case of a 14.32 MHz timer, this happens when the desired frequency exceeds 61 Hz. To avoid this multiplication, we can precompute and store the hardware timer frequency, instead of the period, in the device structure, which leaves us with a simple division when computing the number of timer ticks. As a side effect, this also removes a theoretical bug where the timer interpolator's frequency would be computed as a 32-bit value even if the HPET frequency is greater than 2^32 Hz (the HPET spec allows up to 10 GHz).
