power/reset: at91: fix return value check in at91_reset_platform_probe()

2015-06-10T17:42:45+00:00

[ Upstream commit 932df43005389300a3336421e4aedb25390ae144 ] In case of error, the function devm_ioremap() returns NULL not ERR_PTR(). The IS_ERR() test in the return value check should be replaced with NULL test.

drm/radeon: partially revert "fix VM_CONTEXT*_PAGE_TABLE_END_ADDR handling"

2015-06-10T17:42:44+00:00

[ Upstream commit 7c0411d2fabc2e2702c9871ffb603e251158b317 ] We have that bug for years and some users report side effects when fixing it on older hardware. So revert it for VM_CONTEXT0_PAGE_TABLE_END_ADDR, but keep it for VM 1-15. Signed-off-by: Christian König CC: stable@vger.kernel.org Signed-off-by: Alex Deucher Signed-off-by: Sasha Levin

iwlwifi: pcie: prevent using unmapped memory in fw monitor

[ Upstream commit 553452e5ffc0ed13214a287549627d02d9d7fbdc ] In the case of a DMA mapping error on the last iteration of the loop of the allocation of memory of the FW monitor we indeed free the pages, but don't NULL out the page variable thus allowing for the possibility of setting the FW monitor variables with invalid data to use.

ACPI / init: Fix the ordering of acpi_reserve_resources()

2015-06-10T17:42:40+00:00

[ Upstream commit b9a5e5e18fbf223502c0b2264c15024e393da928 ] Since acpi_reserve_resources() is defined as a device_initcall(), there's no guarantee that it will be executed in the right order with respect to the rest of the ACPI initialization code. On some systems this leads to breakage if, for example, the address range that should be reserved for the ACPI fixed registers is given to the PCI host bridge instead if the race is won by the wrong code path. Fix this by turning acpi_reserve_resources() into a void function and calling it directly from within the ACPI initialization sequence.

rtlwifi: rtl8192cu: Fix kernel deadlock

2015-06-10T17:42:38+00:00

[ Upstream commit 414b7e3b9ce8b0577f613e656fdbc36b34b444dd ] The USB mini-driver in rtlwifi, which is used by rtl8192cu, issues a call to usb_control_msg() with a timeout value of 0. In some instances where the interface is shutting down, this infinite wait results in a CPU deadlock. A one second timeout fixes this problem without affecting any normal operations.
