2006-02-20[PATCH] cfi_cmdset_0001: fix range for cache invalidationAlexey Korolev
I found an issue in cfi_cmdset0001.c. It is related to cache region invalidation in the buffered write procedure. The code performs cache invalidation from "cmd_addr" to "cmd_adr + len" in do_write_buffer() while we modify region from "adr" to "adr+len". This issue affects writes + reads of data by small chunks.

2006-02-20[PATCH] Terminate process that fails on a constrained allocationChristoph Lameter
Some allocations are restricted to a limited set of nodes (due to memory policies or cpuset constraints). If the page allocator is not able to find enough memory then that does not mean that overall system memory is low. In particular going postal and more or less randomly shooting at processes is not likely going to help the situation but may just lead to suicide (the whole system coming down). It is better to signal to the process that no memory exists given the constraints that the process (or the configuration of the process) has placed on the allocation behavior. The process may be killed but then the sysadmin or developer can investigate the situation. The solution is similar to what we do when running out of hugepages. This patch adds a check before we kill processes. At that point performance considerations do not matter much so we just scan the zonelist and reconstruct a list of nodes. If the list of nodes does not contain all online nodes then this is a constrained allocation and we should kill the current process.

2006-02-17[PATCH] ACPI: fix vendor resource length computationBjorn Helgaas
acpi_rs_get_list_length() needs to account for all the vendor-defined data bytes. Failing to include these causes buffers to be sized too small, which causes slab corruption when we later convert AML to resources and run off the end of the buffer. This causes slab corruption on machines that use ACPI vendor-defined resources. All HP ia64 machines do, and I'm told that some NEC machines may as well.

2006-02-17[PATCH] wireless/atmel: fix Open System authentication process bugsDan Williams
This patch fixes a number of bugs in the authentication process: 1) When falling back to Shared Key authentication mode from Open System, a missing 'return' would cause the auth request to be sent, but would drop the card into Management Error state. When falling back, the driver should also indicate that it is switching to Shared Key mode by setting exclude_unencrypted. 2) Initial authentication modes were apparently wrong in some cases, causing the driver to attempt Shared Key authentication mode when in fact the access point didn't support that mode or even had WEP disabled. The driver should set the correct initial authentication mode based on wep_is_on and exclude_unencrypted. 3) Authentication response packets from the access point in Open System mode were getting ignored because the driver was expecting the sequence number of a Shared Key mode response. The patch separates the OS and SK mode handling to provide the correct behavior. Signed-off-by: Dan Williams <dcbw@redhat.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2006-02-15[PATCH] neofb: avoid resetting display config on unblank (v2)Christian Trefzer
There were two mistakes in the register-read-on-(un)blank approach. - First, without proper register (un)locking the value read back will always be zero, and this is what I missed entirely until just now. Due to this, the logic could not be verified at all and I tried some bogus checks which are completely stupid. - Second, the LCD status bit will always be set to zero when the backlight has been turned off. Reading the value back during unblank will disable the LCD unconditionally, regardless of the state it is supposed to be in, since we set it to zero beforehand. So this is what we do now: - create a new variable in struct neofb_par, and use that to determine whether to read back registers (initialized to true) - before actually blanking the screen, read back the register to sense any possible change made through Fn key combo - use proper neoUnlock() / neoLock() to actually read something - every call to neofb_blank() determines if we read back next time: blanking disables readback, unblanking (FB_BLANK_UNBLANK) enables it This should give us a nice and clean state machine. Has been thoroughly tested on a Dell Latitude CPiA / NM220 Chip docked to a C/Dock2 with attached CRT in all possible combinations of LCD/CRT on/off. I changed the config via Fn key, let the console blank, unblanked by keypress - works flawlessly. Signed-off-by: Christian Trefzer <ctrefzer@gmx.de> Cc: "Antonino A.

2006-02-14[PATCH] neofb: avoid resetting display config on unblankChristian Trefzer
Fix issues with the NeoMagic framebuffer driver. It nicely complements my previous fix already in linus' tree. The only thing missing now is that the external CRT will not be activated at neofb init when external-only is selected, either by register read or module/kernel parameter. Testing was done on a Dell Latitude CPi-A/NM2200 chip. Previous behaviour: - before booting linux, set the preferred display config X via FN+F8 - boot linux, neofb stores the register values in a private variable - change the display config to Y via keystroke - leave the machine in peace until display is blanked - touching any key will result in display config X being restored - booting up, the BIOS will acknowledge config Y, though... Current behaviour: At the time of unblanking, config Y is honoured because we now read back register contents instead of just overwriting them with outdated values.

When the _CRS for a single HPET contains multiple EXTENDED_IRQ resources, we overwrote hdp->hd_nirqs every time we found one. So the driver worked when all the IRQs were described in a single EXTENDED_IRQ resource, but failed when multiple resources were used. (Strictly speaking, I think the latter is actually more correct, but both styles have been used.) Someday we should remove all the ACPI stuff from hpet.c and use PNP driver registration instead. But currently PNP_MAX_IRQ is 2, and HPETs often have more IRQs.
