We are taking mbox_lock spinlock which disables pre-emption before we poll for mbox completion. Waiting there with spinlock held in excess of 20s will cause soft lockup. Actual fix is to change mbox_lock to mutex. The changes are done in phases. This is the first part. 1. Changed mgmt_get_all_if_id to use MCC where after posting lock is released. 2. Changed be_mbox_db_ready_wait to busy wait for 12s max and removed wait_event_timeout. Added error handling code for IO reads. OPCODE_COMMON_QUERY_FIRMWARE_CONFIG mbox command takes 8s time when unreachable boot targets configured. Signed-off-by:

In commit 11f1a4b9 ("x86: reorganize SMAP handling in user space accesses") I changed how the stac/clac instructions were generated around the user space accesses, which then made it possible to do batched accesses efficiently for user string copies etc. However, in doing so, I completely spaced out, and didn't even think about the 32-bit case. And nobody really even seemed to notice, because SMAP doesn't even exist until modern Skylake processors, and you'd have to be crazy to run 32-bit kernels on a modern CPU. Which brings us to Andy Lutomirski. He actually tested the 32-bit kernel on new hardware, and noticed that it doesn't work. My bad. The trivial fix is to add the required uaccess begin/end markers around the raw accesses in <asm/uaccess_32.h>. I feel a bit bad about this patch, just because that header file really should be cleaned up to avoid all the duplicated code in it, and this commit just expands on the problem. But this just fixes the bug without any bigger cleanup surgery. Reported-and-tested-by:

Trond Myklebust authored
If the server reboots while there is a layoutget outstanding, then the call to pnfs_choose_layoutget_stateid() will fail with an EAGAIN error, which causes an infinite loop in send_layoutget(). The reason why we never break out of the loop is that the layout 'plh_block_lgets' field is never cleared. Fix is to replace plh_block_lgets with NFS_LAYOUT_INVALID_STID, which can be reset after a new layoutget. Fixes: ab7d763e ("pNFS: Ensure nfs4_layoutget_prepare returns...") Signed-off-by:

The dm9000 driver doesn't work in at least one device-tree configuration, spitting an error message on irq resource : [ 1.062495] dm9000 8000000.ethernet: insufficient resources [ 1.068439] dm9000 8000000.ethernet: not found (-2). [ 1.073451] dm9000: probe of 8000000.ethernet failed with error -2 The reason behind is that the interrupt might be provided by a gpio controller, not probed when dm9000 is probed, and needing the probe deferral mechanism to apply. Currently, the interrupt is directly taken from resources. This patch changes this to use the more generic platform_get_irq(), which handles the deferral. Moreover, since commit Fixes: 7085a740 ("drivers: platform: parse IRQ flags from resources"), the interrupt trigger flags are honored in platform_get_irq(), so remove the needless code in dm9000.
