It's often inconvenient to use BIO_MAX_PAGES due to min() requiring the
sign to be the same.  Introduce bio_max_segs() and change BIO_MAX_PAGES to
be unsigned to make it easier for the users.

<title>scsi: target: tcmu: Fix memory leak caused by wrong uio usage</title>

<id>urn:sha1:8f33bb2400f48a6a319176866af6e7aac9e5211e</id>
<content type='text'>
When user deletes a tcmu device via configFS, tcmu calls
uio_unregister_device(). During that call uio resets its pointer to struct
uio_info provided by tcmu. That means, after uio_unregister_device() uio
will no longer execute any of the callbacks tcmu had set in uio_info.

Especially, if userspace daemon still holds the corresponding uio device
open or mmap'ed while tcmu calls uio_unregister_device(), uio will not call
tcmu_release() when userspace finally closes and munmaps the uio device.

Since tcmu does refcounting for the tcmu device in tcmu_open() and
tcmu_release(), in the decribed case refcount does not drop to 0 and tcmu
does not free tcmu device's resources.  In extreme cases this can cause
memory leaking of up to 1 GB for a single tcmu device.

After uio_unregister_device(), uio will reject every open, read, write,
mmap from userspace with -EOI. But userspace daemon can still access the
mmap'ed command ring and data area. Therefore tcmu should wait until
userspace munmaps the uio device before it frees the resources, as we don't
want to cause SIGSEGV or SIGBUS to user space.

That said, current refcounting during tcmu_open and tcmu_release does not
work correctly, and refcounting better should be done in the open and close
callouts of the vm_operations_struct, which tcmu assigns to each mmap of
the uio device (because it wants its own page fault handler).

This patch fixes the memory leak by removing refcounting from tcmu_open and
tcmu_close, and instead adding new tcmu_vma_open() and tcmu_vma_close()
handlers that only do refcounting.

TCM buffer length doesn't necessarily equal 8 + ADDITIONAL LENGTH which
might be considered an underflow in case of Data-In size being greater than
8 + ADDITIONAL LENGTH. So truncate buffer length to prevent underflow.

TCM doesn't properly handle underflow case for service actions. One way to
prevent it is to always complete command with
target_complete_cmd_with_length(), however it requires access to data_sg,
which is not always available.

This change introduces target_set_cmd_data_length() function which allows
to set command data length before completing it.

<id>urn:sha1:2355a6773a2cb0d2dce13432dde78497f1d6617b</id>
<content type='text'>
The Max imm data size in cxgb4 is not similar to the max imm data size
in the chtls. This caused an mismatch in output of is_ofld_imm() of
cxgb4 and chtls. So fixed this by keeping the max wreq size of imm data
same in both chtls and cxgb4 as MAX_IMM_OFLD_TX_DATA_WR_LEN.

As cxgb4's max imm. data value for ofld packets is changed to
MAX_IMM_OFLD_TX_DATA_WR_LEN. Using the same in cxgbit also.
