2008-12-21tg3: tg3.h cleanupsMatt Carlson
This patch cleans up the tg3 header file by removing the preprocessor definitions for standard PCI configuration space registers. The driver should be using the standard definitions when needed. The patch continues by removing redundant PHY related definitions and reorganizes some of the remaining entries.

2008-12-21tg3: Remove unused cfgspc device membersMatt Carlson
This patch removes the pci_bist and pci_hdr_type members from the device structure and removes the code that references them. They are not really used. The patch rounds out the changes by moving the pci_cmd member to plug a structure hole that would have been created. On 32-bit systems, this movement removes a subsequent structure hole later in the structure. On 64-bit systems though, the movement merely consolidates two holes into one larger hole.

2008-12-21tg3: WOL fixesMatt Carlson
The first hunk of this patch inverts a flag that was accidentally toggled as part of commit 0a459aac9d151c2e36ec65723b9b845b24c5cbc3 ("tg3: Allow WOL for phylib controlled Broadcom phys"). The second hunk of the patch removes the call to device_may_wakeup() in the 5906 config detection path. At the point of the call, the driver shouldn't be querying for WOL capability. It should be detecting and setting it.

2008-12-21IB/iser: Avoid recv buffer exhaustion caused by unexpected PDUsDavid Disseldorp
iSCSI/iSER targets may send PDUs without a prior request from the initiator. RFC 5046 refers to these PDUs as "unexpected". NOP-In PDUs with itt=RESERVED and Asynchronous Message PDUs occupy this category. The amount of active "unexpected" PDU's an iSER target may have at any time is governed by the MaxOutstandingUnexpectedPDUs key, which is not yet supported. Currently when an iSER target sends an "unexpected" PDU, the initiators recv buffer consumed by the PDU is not replaced. If over initial_post_recv_bufs_num "unexpected" PDUs are received then the receive queue will run out of receive work requests entirely. This patch ensures recv buffers consumed by "unexpected" PDUs are replaced in the next iser_post_receive_control() call.

2008-12-21powerpc/mpc5200: Add MDMA/UDMA support to MPC5200 ATA driverTim Yamin
This patch adds MDMA/UDMA support using BestComm for DMA on the MPC5200 platform. Based heavily on previous work by Freescale (Bernard Kuhn, John Rigby) and Domen Puncer.

2008-12-21powerpc/mpc5200: Bestcomm fixes to ATA supportTim Yamin
1) ata.h has dst_pa in the wrong place (needs to match what the BestComm task microcode in bcom_ata_task.c expects); fix it. 2) The BestComm ATA task priority was changed to maximum in bestcomm_priv.h; this fixes a deadlock issue experienced with heavy DMA occurring on both the ATA and Ethernet BestComm tasks, e.g. when downloading a large file over a LAN to disk.

2008-12-21powerpc/mpc5200: Bugfix on handling variable sized buffer descriptorsGrant Likely
The buffer descriptors for the ATA BestComm task are larger than the current definition for bcom_bd. This causes problems because the various bcom_... functions dereference the buffer descriptor pointer by using the array operator which doesn't work when the buffer descriptors are a different size. This patch adds the bcom_get_bd() function which uses the value in bcom_task.bd_size to calculate the offset into the BD table. This patch also changes the definition of bcom_bd to specify a data size of 0 instead of 1 so that it will never work if anyone attempts to dereference the bd list as an array (as opposed to something that might work even though it is wrong). Finally, this patch moves the definition of bcom_bd up in the file to eliminate a forward declaration. Based on patch originally written by Tim Yamin.

2008-12-21powerpc/mpc5200: Make internal 5200 PIC the default interrupt controllerGrant Likely
The MPC5200 internal interrupt controller setup function needs to set the default interrupt controller when it is called.

2008-12-21powerpc/mpc5200: Document and tidy irq driverGrant Likely
This patch adds documentation to the mpc5200 interrupt controller driver and cleans up some minor coding conventions. It also moves the contents of mpc52xx_pic.h into the driver proper (except for a small common bit that is moved to the common mpc52xx.h) because the information encoded there is not required by any other part of kernel code. Finally for code readability sake, the L2_OFFSET shift value is removed because the code using it resolves to a noop. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

2008-12-21powerpc/44x: 44x TLB doesn't need "Guarded" set for all pagesBenjamin Herrenschmidt
After discussing with chip designers, it appears that it's not necessary to set G everywhere on 440 cores. The various core errata related to prefetch should be sorted out by firmware by disabling icache prefetching in CCR0. We add the workaround to the kernel however just in case oooold firmwares don't do it. This is valid for -all- 4xx core variants. Later ones hard wire the absence of prefetch but it doesn't harm to clear the bits in CCR0 (they should already be cleared anyway). We still leave G=1 on the linear mapping for now, we need to stop over-mapping RAM to be able to remove it.

2008-12-21powerpc/mm: Rework usage of _PAGE_COHERENT/NO_CACHE/GUARDEDBenjamin Herrenschmidt
Currently, we never set _PAGE_COHERENT in the PTEs, we just OR it in in the hash code based on some CPU feature bit. We also manipulate _PAGE_NO_CACHE and _PAGE_GUARDED by hand in all sorts of places. This changes the logic so that instead, the PTE now contains _PAGE_COHERENT for all normal RAM pages thay have I = 0 on platforms that need it. The hash code clears it if the feature bit is not set. It also adds some clean accessors to setup various valid combinations of access flags and change various bits of code to use them instead. This should help having the PTE actually containing the bit combinations that we really want. I also removed _PAGE_GUARDED from _PAGE_BASE on 44x and instead set it explicitely from the TLB miss. I will ultimately remove it completely as it appears that it might not be needed after all but in the meantime, having it in the TLB miss makes things a lot easier.

2008-12-21powerpc/mm: Runtime allocation of mmu context maps for nohash CPUsBenjamin Herrenschmidt
This makes the MMU context code used for CPUs with no hash table (except 603) dynamically allocate the various maps used to track the state of contexts. Only the main free map and CPU 0 stale map are allocated at boot time. Other CPU maps are allocated when those CPUs are brought up and freed if they are unplugged. This also moves the initialization of the MMU context management slightly later during the boot process, which should be fine as it's really only needed when userland if first started anyways.
