* powerpc/85xx: Add host-pci(e) bridge only for RCPrabhakar Kushwaha2011-06-271-0/+13
| | | | | | | | | | | FSL PCIe controller can act as agent(EP) or host(RC). Under Agent(EP) mode the controller will be configured by the host system. So its not required to be registered with the PCI(e) sub-system. We only register the controller if its configured in host(RC) mode.

| | | | | | | | | | | | | | Add functions to restart and halt the current partition when running under the Freescale hypervisor. These functions should be assigned to various function pointers of the ppc_md structure during the .probe() function for the board: ppc_md.restart = fsl_hv_restart; ppc_md.power_off = fsl_hv_halt; ppc_md.halt = fsl_hv_halt; Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* powerpc: introduce the ePAPR embedded hypervisor vmpic driverAshish Kalra2011-06-274-0/+347
| | | | | | | | | | | | | | | | | | | | | | The Freescale ePAPR reference hypervisor provides interrupt controller services via a hypercall interface, instead of emulating the MPIC controller. This is called the VMPIC. The ePAPR "virtual interrupt controller" provides interrupt controller services for external interrupts. External interrupts received by a partition can come from two sources: - Hardware interrupts - hardware interrupts come from external interrupt lines or on-chip I/O devices. - Virtual interrupts - virtual interrupts are generated by the hypervisor as part of some hypervisor service or hypervisor-created virtual device. Both types of interrupts are processed using the same programming model and same set of hypercalls.

* powerpc: introduce ePAPR embedded hypervisor hcall interfaceTimur Tabi2011-06-272-0/+1157
| | | | | | | | | | | | | | | | | | ePAPR hypervisors provide operating system services via a "hypercall" interface. The following steps need to be performed to make an hcall: 1. Load r11 with the hcall number 2. Load specific other registers with parameters 3. Issue instrucion "sc 1" 4. The return code is in r3 5. Other returned parameters are in other registers. To provide this service to the kernel, these steps are wrapped in inline assembly functions. Standard ePAPR hcalls are in epapr_hcalls.h, and Freescale extensions are in fsl_hcalls.h.

* powerpc/85xx: Save scratch registers to thread info instead of using SPRGs.Ashish Kalra2011-06-225-40/+63
| | | | | | | | | | | | | | We expect this is actually faster, and we end up needing more space than we can get from the SPRGs in some instances. This is also useful when running as a guest OS - SPRGs4-7 do not have guest versions. 8 slots are allocated in thread_info for this even though we only actually use 4 of them - this allows space for future code to have more scratch space (and we know we'll need it for things like hugetlb).

* powerpc: Avoid extra indirect function call in sending IPIsPaul Mackerras2011-06-206-9/+19
| | | | | | | | | | | | | | | On many platforms (including pSeries), smp_ops->message_pass is always smp_muxed_ipi_message_pass. This changes arch/powerpc/kernel/smp.c so that if smp_ops->message_pass is NULL, it calls smp_muxed_ipi_message_pass directly. This means that a platform doesn't need to set both .message_pass and .cause_ipi, only one of them. It is a slight performance improvement in that it gets rid of an indirect function call at the expense of a predictable conditional branch.

* | vfs: reorganize 'struct inode' layout a bitLinus Torvalds2011-06-081-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This tries to make the 'struct inode' accesses denser in the data cache by moving a commonly accessed field (i_security) closer to other fields that are accessed often. It also makes 'i_state' just an 'unsigned int' rather than 'unsigned long', since we only use a few bits of that field, and moves it next to the existing 'i_flags' so that we potentially get better structure layout (although depending on config options, i_flags may already have packed in the same word as i_lock, so this improves packing only for the case of spinlock debugging) Out 'struct inode' is still way too big, and we should probably move some other fields around too (the acl fields in particular) for better data cache access density. Other fields (like the inode hash) are likely to be entirely irrelevant under most loads. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* | selinux: simplify and clean up inode_has_perm()Linus Torvalds2011-06-081-10/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a rather hot function that is called with a potentially NULL "struct common_audit_data" pointer argument. And in that case it has to provide and initialize its own dummy common_audit_data structure. However, all the _common_ cases already pass it a real audit-data structure, so that uncommon NULL case not only creates a silly run-time test, more importantly it causes that function to have a big stack frame for the dummy variable that isn't even used in the common case! So get rid of that stupid run-time behavior, and make the (few) functions that currently call with a NULL pointer just call a new helper function instead (naturally called inode_has_perm_noapd(), since it has no adp argument). This makes the run-time test be a static code generation issue instead, and allows for a much denser stack since none of the common callers need the dummy structure. And a denser stack not only means less stack space usage, it means better cache behavior. So we have a win-win-win from this simplification: less code executed, smaller stack footprint, and better cache behavior. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

The Corsair Padlock v2 returns completely bogus data for its first read (possibly it returns the data in encrypted form even though the device is supposed to be unlocked). The Feiya SD/SDHC card reader fails to complete the first READ(10) command after it is plugged in or after a new card is inserted, returning a status code that indicates it thinks the command was invalid, which prevents the kernel from retrying the read. Since the first read of a new device or a new medium is for the partition sector, the kernel is unable to retrieve the device's partition table. Users have to manually issue an "hdparm -z" or "blockdev --rereadpt" command before they can access the device. This patch (as1470) works around the problem. It adds a new quirk flag, US_FL_INVALID_READ10, indicating that the first READ(10) should always be retried immediately, as should any failing READ(10) commands (provided the preceding READ(10) command succeeded, to avoid getting stuck in a loop). The patch also adds appropriate unusual_devs entries containing the new flag.

There used to be exactly one dput per dentry_unhash call; now there are none.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Protocol stall should not be fatal while reading port or hub status as it is transient state. Currently hub EP0 STALL during port status read results in failed device enumeration. This has been observed with ST-Ericsson (formerly Philips) USB 2.0 Hub (04cc:1521) after connecting keyboard.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds the Nokia E7 and C7 to the list of devices in cdc-acm, allowing the secondary ACM channel on the device to be exposed. Without this patch the ACM driver won't claim this secondary channel as it's marked as having a vendor-specific protocol.
