* pcmcia: add new CIS access helpersDominik Brodowski2009-11-086-46/+304
| | | | | | | | | | | | | | | | | | | | | | | | As a replacement to pcmcia_get_{first,next}_tuple() and pcmcia_get_tuple_data(), three new -- and easier to use -- functions are added: - pcmcia_get_tuple() to get the very first CIS entry of one type. - pcmcia_loop_tuple() to loop over all CIS entries of one type. - pcmcia_get_mac_from_cis() to read out the hardware MAC address from CISTPL_FUNCE. Only a handful of drivers need these functions anyway, as most CIS access is already handled by pcmcia_loop_config(), which now shares the same backed (pccard_loop_tuple()) with pcmcia_loop_tuple(). A pcmcia_get_mac_from_cis() bug noted by Komuro <komurojun-mbn@nifty.com> has been fixed in this revision. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
* ipwireless: make more use of pcmcia_loop_config()Dominik Brodowski2009-11-081-114/+99
| | | | | | | | | | Within the pcmcia_loop_config() callback, we already have all tuple data available we need. Also add a fix to release the IO resource (at least within pcmcia_loop_config() error path).

* pcmcia: use pcmcia_loop_config in misc pcmcia driversDominik Brodowski2009-11-084-168/+88
| | | | | | | | | | | | | | | Use pcmcia_loop_config() in a few drivers missed during the first round. On fmvj18x_cs.c it -- strangely -- only requries us to set conf.ConfigIndex, which is done by the core, so include an empty loop function which returns 0 unconditionally. CC: David S.

* pcmcia: use pre-determined valuesDominik Brodowski2009-11-084-45/+19
| | | | | | | | | | | | | | | | | | | | | A few PCMCIA network drivers can make use of values provided by the pcmcia core, instead of tedious, independent CIS parsing. xirc32ps_cs.c: manf_id hostap_cs.c: multifunction count b43/pcmcia.c: ConfigBase address and "Present" smc91c92_cs.c: By default, mhz_setup() can use VERS_1 as it is stored in struct pcmcia_device.

* serial_cs: use pcmcia_loop_config() and pre-determined valuesDominik Brodowski2009-10-241-64/+23
| | | | | | | | | | | | As the PCMCIA core already determines the multifunction count, the ConfigBase address and the Present value, we can use them directly instead of parsing the CIS again. By making use of pcmcia_loop_config(), we can further remove the remaining call to pcmcia_get_first_tuple() and friends.

* pcmcia: pccard_read_tuple and TUPLE_RETURN_COMMON cleanupDominik Brodowski2009-10-196-17/+18
| | | | | | | | | | | | | | | | | pccard_read_tuple(), which is only used by the PCMCIA core, should handle TUPLE_RETURN_COMMON more sensibly: If a specific function (which may be 0) is requested, set tuple.Attributes = 0 as was done in all PCMCIA drivers. If, however, BIND_FN_ALL is requested, return the "common" tuple. As to the callers of pccard_read_tuple(): - All calls to pcmcia_validate_cis() had set the "function" parameter to BIND_FN_ALL. Therefore, remove the "function" parameter and make the parameter to pccard_read_tuple explicit. - Calls to CISTPL_VERS_1 and CISTPL_MANFID now set BIND_FN_ALL. This was already the case for calls to CISTPL_LONGLINK_MFC. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>

* | | | | KEYS: get_instantiation_keyring() should inc the keyring refcount in all casesDavid Howells2009-10-151-1/+1

This is passed in the request_key_auth struct as the dest_keyring member. keyctl_instantiate_key and keyctl_negate_key() call get_instantiation_keyring() to get the keyring to attach the newly constructed key to at the end of instantiation. This may be given a specific keyring into which a link will be made later, or it may be asked to find the keyring passed to request_key(). In the former case, it returns a keyring with the refcount incremented by lookup_user_key(); in the latter case, it returns the keyring from the request_key_auth struct - and does _not_ increment the refcount. The latter case will eventually result in an oops when the keyring prematurely runs out of references and gets destroyed. The effect may take some time to show up as the key is destroyed lazily. To fix this, the keyring returned by get_instantiation_keyring() must always have its refcount incremented, no matter where it comes from. This can be tested by setting /etc/request-key.conf to: #OP TYPE DESCRIPTION CALLOUT INFO PROGRAM ARG1 ARG2 ARG3 ... #====== ======= =============== =============== =============================== create * test:* * |/bin/false %u %g %d %{user:_display} negate * * * /bin/keyctl negate %k 10 @u and then doing: keyctl add user _display aaaaaaaa @u while keyctl request2 user test:x test:x @u && keyctl list @u; do keyctl request2 user test:x test:x @u; sleep 31; keyctl list @u; done which will oops eventually. Changing the negate line to have @u rather than %S at the end is important as that forces the latter case by passing a special keyring ID rather than an actual keyring ID.

If it is, is also prints out the saved real return address. On powerpc64, some modules may return to mod_return_to_handler, which is not checked. This patch will also show the real address if a return is to mod_return_to_handler as well. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>

However, the SLB miss handler code to discriminate between vmalloc and ioremap space uses a CPU feature section such that the code is nop'ed out when the processor support large pages non-cachable mappings. Thus, we end up always using the ioremap page size for vmalloc segments on such processors, causing a discrepency between the segment and the hash table, and thus a hang continously hashing the page. It works for the first segment of the vmalloc space since that segment is "bolted" in by C code correctly, and thankfully we almost never use the vmalloc space beyond the first segment, but the new percpu code made the bug happen. This fixes it by removing the feature section from the assembly, we now always do the comparison between vmalloc and ioremap.

I finally tracked it down to the code that runs various "platform" functions (kind of little scripts extracted from the device-tree), which uses our i2c and PMU drivers expecting interrutps to work, and at a time where with the new scheme, they have been disabled. This causes timeouts internally which for some reason results in the PMU being unable to see the trackpad, among other issues, really it depends on the machine. Most of the time, we fail to properly adjust some clocks for suspend/resume so the results are not always predictable. This patch fixes it by using IRQF_TIMER for both the PMU and the I2C interrupts. I prefer doing it this way than moving the call sites since I really want those platform functions to still be called after all drivers (and before sysdevs). We also do a slight cleanup to via-pmu.c driver to make sure the ADB autopoll mask is handled correctly when doing bus resets Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

Some broken BIOSes prevented working backlight control by only defining both for one (non-existing bus) and only _DOD for the rest. With this patch in place the other bus definitions were considered too and backlight control started to work again.

It does so by ensuring that the rfkill soft-block flag is set before the hardware is disabled. I do not know whether this patch is required if rt2800pci is in use instead of rt2860sta; at the time of submission of this patch, I've not been able to test this.

Use __devinit for both functions which is more appropriate and fixes a section mismatch warning. We were warned by the following warning: LD drivers/platform/x86/built-in.o WARNING: drivers/platform/x86/built-in.o(.text+0x12e1): Section mismatch in reference from the function eeepc_hotk_add() to the function .init.text:eeepc_enable_camera() The function eeepc_hotk_add() references the function __init eeepc_enable_camera(). This is often because eeepc_hotk_add lacks a __init annotation or the annotation of eeepc_enable_camera is wrong.

However, it assumes that every handle it finds in the ACPI CA name space, between given device handle and the PCI root bridge handle, corresponds to a PCI-to-PCI bridge with an existing secondary bus. For this reason, when it finds a struct pci_dev object corresponding to one of them, it doesn't check if its 'subordinate' field is a valid pointer. This obviously leads to a NULL pointer dereference if acpi_get_pci_dev() is called for a non-PCI device with a PCI parent which is not a bridge. To fix this issue make acpi_get_pci_dev() check if pdev->subordinate is not NULL for every device it finds on the path between the root bridge and the device it's supposed to get to and return NULL if the "target" device cannot be found. http://bugzilla.kernel.org/show_bug.cgi?id=14129 (worked in 2.6.30, regression in 2.6.31) Signed-off-by: Rafael J.
