2007-01-05[PATCH] Fix BUG at drivers/scsi/scsi_lib.c:1118 caused by "pktsetup dvd ↵Christoph Hellwig
/dev/sr0" Fix http://bugzilla.kernel.org/show_bug.cgi?id=7667 This is because the packet driver tries to send down read/write BLOCK_PC commands that don't use a bio and do not use sg lists. The right fix is to replace all the packet_command stuff in the packet driver by scsi_execute() which needs to be lifted from scsi code to the block code for that. Fix the bug for now. It's not the full way to a generic execute block pc infrastcuture but fixes the bug for the time being.

2007-01-05[PATCH] KVM: Improve interrupt responseDor Laor
The current interrupt injection mechanism might delay an interrupt under the following circumstances: - if injection fails because the guest is not interruptible (rflags.IF clear, or after a 'mov ss' or 'sti' instruction). Userspace can check rflags, but the other cases or not testable under the current API. - if injection fails because of a fault during delivery. This probably never happens under normal guests. - if injection fails due to a physical interrupt causing a vmexit so that it can be handled by the host. In all cases the guest proceeds without processing the interrupt, reducing the interactive feel and interrupt throughput of the guest. This patch fixes the situation by allowing userspace to request an exit when the 'interrupt window' opens, so that it can re-inject the interrupt at the right time. Guest interactivity is very visibly improved.

2007-01-05[PATCH] via82cxxx: fix cable detectionBartlomiej Zolnierkiewicz
This patch fixes 2.6.15 regression, is straightforward and tested. Cable detection got broken probably while converting the driver to support multiple controllers. Cable detection is done by examining how BIOS configured the attached devices. The current code is broken in that it examines the status *after* modifying Clk66 configuration ending up detecting 40c cables as 80c. This patch fixes it.

2007-01-05[PATCH] PCI: prevent down_read when pci_devices is emptyArd van Breemen
The pci_find_subsys gets called very early by obsolete ide setup parameters. This is a bogus call since pci is not initialized yet, so the list is empty. But in the mean time, interrupts get enabled by down_read. This can result in a kernel panic when the irq controller gets initialized. This patch checks if the device list is empty before taking the semaphore, and hence will not enable irq's. Furthermore it will inform that it is called while pci_devices is empty as a reminder that the ide code needs to be fixed. The pci_get_subsys can get called in the same manner, and as such is patched in the same manner.

2007-01-05[PATCH] kernelparams: detect if and which parameter parsing enabled irq'sArd van Breemen
The parsing of some kernel parameters seem to enable irq's at a stage that irq's are not supposed to be enabled (Particularly the ide kernel parameters).

It's a known fact that Windows times out commands after 7 seconds, so drives generally try and respond if they can before that happens. We default to 5 seconds, which sometimes is a bit too short. Jeremy Higdon reported here: http://lkml.org/lkml/2007/1/1/145 that his drive takes longer than 5 seconds for a "read track information" command, later confirming that it is about 6.7 seconds.

This is patch that solves Ebox mini PC issue and make FSB code more specification compilant. At start guess_fsb function is guessing 200MHz FSB too. It is better to make it in this way because, thanks to this function, driver will fail for bogus FSB values caused by bogus multiplier value. For PowerSaver processors we can't depend on Max / MinMHzFSB because these values are only used for PowerSaver 2.0 and 3.0. Most processors on which Longhaul is used are PowerSaver 1.0 only. I'm changing code for older CPU's too, but not so much as previously, and this code was already used for Ezra. Using MinMHzBR for Ezra-T is outside spec. It is for voltage scaling purpose and don't have to be equal to minmult (but it is). Same for Nehemiah (it isn't for sure). Added mult - current multiplier value.

Commit 968de4f02621db35b8ae5239c8cfc6664fb872d8 ("i386: Relocatable kernel support") caused problems for people with old binutils versions that didn't mark ".text.*" sections automatically allocated. So we should use .section command to specifically mark .text.head section as AX (allocatable and executable) to solve the problem. This should be unnecessary with binutils 2.15 and later, which is already three years old, but it doesn't hurt supporting older toolchains where possible.
