With flatmem hibernation for Loongson will fail, and there are also some
other problems such as broken files when using NFS or CIFS / Samba.The config help of sparsemem says:
"This option provides some potential performance benefits, along with
decreased code complexity."So to avoid the potential problems of FLATMEM, we disable FLATMEM directly
and use SPARSEMEM instead.Related email thread:

Currently, with PAGE_SIZE_4KB, the kernel for loongson will hang on:
Kernel panic - not syncing: Attempted to kill init!
The possible reason is the cache aliases problem:
Loongson 2F has 64kb, 4 way L1 Cache, the way size is 16kb, which is bigger
then 4kb. so, If using 4kb page size, there is cache aliases problem.
To avoid this kind of problem, extra cache flushing. The 2nd possible
solution is 16kb page size which avoids cache aliases without the need for
extra cache flushes. So we disable 4kB pages until the aliasing issue is
solved.Signed-off-by: Wu Zhangjin

Some Debian users have reported that the kernel hangs early during boot on
some IP22 systems. Thomas Bogendoerfer found that this is due to a "bad
interaction between CONFIG_EARLY_PRINTK and overwritten prom memory during
early boot". Since there's no fix yet, disable CONFIG_EARLY_PRINTK for now.Signed-off-by: Martin Michlmayr

Commits 3d7a641 ("SLOW_WORK: Wait for outstanding work items belonging to a

slow-work items were complete before that module was removed, and commit
3bde31a ("SLOW_WORK: Allow a requeueable work item to sleep till the thread is
needed") further extended that, breaking it in the process if CONFIG_MODULES=n:CC kernel/slow-work.o

make[1]: *** [kernel/slow-work.o] Error 1Fix this by:
(1) Extracting the bits of slow_work_execute() that are contingent on
CONFIG_MODULES, and the bits that should be, into inline functions and
placing them into the #ifdef'd section that defines the relevant variables
and adding stubs for moduleless kernels. This allows the removal of some
#ifdefs.(2) #ifdef'ing out the contents of slow_work_wait_for_items() in moduleless
kernels.The four functions related to handling module unloading synchronisation (and
their associated variables) could be offloaded into a separate .c file, but
each function is only used once and three of them are tiny, so doing so would
prevent them from being inlined.Reported-by: Ingo Molnar

This patch adds the vendor and device id for the Mobilcom Debitel UMTS surf
stick (a.k.a. 4G Systems XSStick W14, MobiData MBD-200HU, ...).To see these ids, you need to switch the stick to modem operation first

On tx channel abort a cppi interrupt is generated for a short time by
setting the lowest bit of the TCPPICOMPPTR register. It is then reset
immediately by clearing the bit. When the interrupt handler is run,
it does not detect an interrupt in the TCPPIMSKSR or RCPPIMSKSR
registers and thus exits early without writing the TCPPIEOIR register.
It appears that this inhibits further cppi interrupts until the handler
is called by chance, f.ex. from davinci_interrupt().By moving the unmasking of the interrupt below the writes to
TCPPICOMPPTR, no interrupt is generated and no write to TCPPIEOIR is
necessary.Signed-off-by: Daniel Glöckner

In gadget mode the answer to a control request should be followed by
a zero-length packet if the amount transferred is an exact multiple of
the endpoint's packet size and the requests has its "zero" flag set.This patch prevents the request from being immediately removed from the
queue when a control IN transfer ends on a full packet and "zero" is set.
The next time ep0_txstate is entered, a zero-length packet is queued and
the request is removed as fifo_count is 0.Signed-off-by: Daniel Glöckner

The use of urb->actual_length to update tx_outstanding_bytes
implicitly assumes that the number of bytes actually written is the
same as the number of bytes we tried to write. On error that
assumption is violated so just use transfer_buffer_length the number
of bytes we intended to write to the device.If an error occurs we need to fall through and call
usb_serial_port_softint to wake up processes waiting in
tty_wait_until_sent.Signed-off-by: Eric W. Biederman

The driver incorrectly cancels the mass-storage device CSW request
(which leads to device reset) due to giving back URB at the head of
endpoint's queue after sending each STALL handshake; stop doing that
and start checking for the queue being non-empty before stalling an
endpoint and disallowing stall in such case in musb_gadget_set_halt()
like the other gadget drivers do.Moreover, the driver starts Rx request despite of the endpoint being
halted -- fix this by moving the SendStall bit check from musb_g_rx()
to rxstate(). And we also sometimes get into rxstate() with DMA still
active after clearing an endpoint's halt (not clear why), so bail out
in this case, similarly to what txstate() does...While at it, also do the following changes :
- in musb_gadget_set_halt(), remove pointless Tx FIFO flushing (the
driver does not allow stalling with non-empty Tx FIFO anyway);- in rxstate(), stop pointlessly zeroing the 'csr' variable;
- in musb_gadget_set_halt(), move the 'done' label to a more proper
place;- in musb_g_rx(), eliminate the 'done' label completely...

This patch (as1304) fixes a regression in ehci-hcd. Evidently some
hubs don't handle Clear-TT-Buffer requests correctly, so we should
avoid sending them when they don't appear to be absolutely necessary.
The reported symptom is that output on a downstream audio device cuts
out because the hub stops relaying isochronous packets.The patch prevents Clear-TT-Buffer requests from being sent following
a STALL handshake. In theory a STALL indicates either that the
downstream device sent a STALL or that no matching TT buffer could be
found. In either case, the transfer is completed and the TT buffer
does not remain busy, so it doesn't need to be cleared.Also, the patch fixes a minor flaw in the code that actually sends the
Clear-TT-Buffer requests. Although the pipe direction isn't really
used for control transfers, it should be a Send rather than a Receive.Signed-off-by: Alan Stern
