Maria Yu 74d2059dc4 arm64: module: Fix PLT counting when CONFIG_RANDOMIZE_BASE=n 
commit d35686444f upstream.

The counting of module PLTs has been broken when CONFIG_RANDOMIZE_BASE=n
since commit:

  3e35d303ab ("arm64: module: rework module VA range selection")

Prior to that commit, when CONFIG_RANDOMIZE_BASE=n, the kernel image and
all modules were placed within a 128M region, and no PLTs were necessary
for B or BL. Hence count_plts() and partition_branch_plt_relas() skipped
handling B and BL when CONFIG_RANDOMIZE_BASE=n.

After that commit, modules can be placed anywhere within a 2G window
regardless of CONFIG_RANDOMIZE_BASE, and hence PLTs may be necessary for
B and BL even when CONFIG_RANDOMIZE_BASE=n. Unfortunately that commit
failed to update count_plts() and partition_branch_plt_relas()
accordingly.

Due to this, module_emit_plt_entry() may fail if an insufficient number
of PLT entries have been reserved, resulting in modules failing to load
with -ENOEXEC.

Fix this by counting PLTs regardless of CONFIG_RANDOMIZE_BASE in
count_plts() and partition_branch_plt_relas().

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
