From 2e4bef41a0f7df31be140ef354b9c12f2299016a Mon Sep 17 00:00:00 2001 From: Eric Van Hensbergen Date: Tue, 24 Jun 2008 17:39:39 -0500 Subject: 9p: fix O_APPEND in legacy mode The legacy protocol's open operation doesn't handle an append operation (it is expected that the client take care of it). We were incorrectly passing the extended protocol's flag through even in legacy mode. This was reported in bugzilla report #10689. This patch fixes the problem by disallowing extended protocol open modes from being passed in legacy mode and implemented append functionality on the client side by adding a seek after the open.

Which is problematic, since non-NUMA only has a single node_zonelists[] entry, and trying to zero the non-existent second one just overwrote the nr_zones field instead. As kswapd uses this value to determine what reclaim work is necessary, the result is that kswapd never reclaims. This causes processes to stall frequently in low-memory situations as they always direct reclaim. This patch initialises zlcache_ptr correctly.

This seems to be a longstanding bug, possibly dating back to the Linux 2.4 kernel, which stayed hidden because (a) about half the time the data toggle bit was correct; (b) canceling such URBs is unusual; and (c) the few drivers which cancel these URBs either [1] do it only as part of shutting down, or [2] have fault recovery logic, which recovers. For those transfer types, the toggle is normally written back into the ED when each TD is retired. But canceling bypasses the mechanism used to retire TDs ... so on average, half the time the toggle bit will be invalid after cancelation. The fix is simple: the toggle state of any canceled TDs are propagated back to the ED in the finish_unlinks function. (Issue found by leonidv11@gmail.com ...)

Remove dev_info call on disconnect. The sisusb_dev pointer may have been set to zero by sisusb_delete at this point causing an oops. The message does not provide any extra information over the standard USB subsystem output so removing it does not affect functionality.

Most USB HCD handlers use IRQF_DISABLED and therefore havoc can break out if they share their interrupt with a handler that doesn't use it. On my test machine the yenta_socket interrupt handler (no IRQF_DISABLED) was registered before ehci_hcd and one uhci_hcd instance. Therefore all usb_hcd_irq() invocations for ehci_hcd and for one uhci_hcd instance happened with interrupts enabled. That led to random lockups as USB core HCD functions that acquire the same spinlock could be called twice from interrupt handlers. This patch updates usb_hcd_irq() to always disable/restore interrupts. usb_add_hcd() will silently remove any IRQF_DISABLED requested from HCD code.

Changed against the original Freescale code (and against clocklib for example): - clock rate is always calculated whenever one ask for the current rate (means struct clk has no more a member called "rate"). So switching the PLL base frequency will propagate immediately to all other clocks that are depending on this frequency.

d0f349fbce2905607e0473d2358f97f48866e52c Mon Sep 17 00:00:00 2001 From: Juergen Beisert Date: Sat, 5 Jul 2008 10:02:50 +0200 Subject: i.MXC family: Adding timer support This patch adds timer support for the i.MX machine family. This code can be used on the following machs: - i.MX1 (tested) - i.MX2 (i.MX21 (to be tested), i.MX27 (tested)) - i.MX3 (i.MX31 (tested)) TODO: It seems impossible to build a kernel for more than one CPU because the timer do not follow the platform device rules. So it does only work if timer 1 can be accessed on all CPUs at the same address.

Changed against the original Freescale code (and against clocklib for example): - clock rate is always calculated whenever one ask for the current rate. (means no "rate" member in the clock structure). So switching the PLL base frequency will propagate immediately to all other clocks that are depending on this frequency. TODO: - Check if the i.MX21 CPU can share the same code.

It is as generic as possible in order to support any kind of baseboard. Note: This CPU module implementation can't work without a baseboard support. Baseboard support can be added by the PCM-970 (included in this patch stack) or any custom variant.
