You are given a class called `JrnlAnalyzer` that is responsible for analyzing a set of journal files. The `JrnlAnalyzer` class contains several methods for performing various operations on the journal files. Your task is to implement one of these methods called `get_mismatch_list`.

The `get_mismatch_list` method takes as input an `xid` (transaction ID) and returns a list of mismatched IDs. To accomplish this, the method performs the following steps:

1. If the `xid` exists in the `self.__map` dictionary, retrieve the corresponding `hdr` (header) object.
2. If the `hdr` object's `deq_rid` (dequeued record ID) is greater than or equal to zero, unlock the `deq_rid` by calling the `unlock` method of the `self.__emap` object.
3. Delete the `deq_rid` from the `self.__emap` object.
4. If the `deq_rid` is not greater than or equal to zero, add its value (in hexadecimal format) to the `mismatch_list`.
5. Remove the `xid` from the `self.__map` dictionary.
6. Return the `mismatch_list`.

Your task is to implement the `get_mismatch_list` method of the `JrnlAnalyzer` class.

Write a function `analyze_journal_files` that takes a list of `xids` and uses the `JrnlAnalyzer` class to analyze the journal files. This function should return a dictionary where the keys are the input `xids` and the values are the mismatch lists obtained from the `get_mismatch_list` method.

Sure, here's a Python function `analyze_journal_files` that takes a list of `xids` and uses the `JrnlAnalyzer` class to analyze the journal files, and returns a dictionary where the keys are the input `xids` and the values are the mismatch lists obtained from the `get_mismatch_list` method. Note that this is just a skeleton code and needs to be supplemented with specifics of your program.

```python
class JrnlAnalyzer:
    def __init__(self, journal_file_path):
        self.journal_file_path = journal_file_path
        # other initialization code goes here

    # other methods go here

    def get_mismatch_list(self, xid):
        # implementation goes here

def analyze_journal_files(xid_list, journal_analyzer):
    """
    Analyzes the given list of `xids` using the given `JrnlAnalyzer`
    instance and returns a dictionary where the keys are the input
    `xids` and the values are the mismatch lists obtained from the
    `get_mismatch_list` method.

    :param xid_list: A list of transaction IDs (`xids`)
    :param journal_analyzer: A `JrnlAnalyzer` instance
    :return: A dictionary with xid as key and mismatch list as value
    """
    mismatch_dictionaries = {}
    for xid in xid_list:
        mismatch_list = journal_analyzer.get_mismatch_list(xid)
        mismatch_dictionaries[xid] = mismatch_list
    return mismatch_dictionaries
```

You can call this function as follows:

```python
analyzer = JrnlAnalyzer(journal_file_path)
xid_list = [1234, 5678, 9012]
result = analyze_journal_files(xid_list, analyzer)
print(result)
```

This will return a dictionary with keys being `xids` and values being the mismatch lists.

Sure, here is the implementation of the `get_mismatch_list` method for the `JrnlAnalyzer` class and the `analyze_journal_files` function:

```python
class JrnlAnalyzer:
    def __init__(self):
        self.__map = {}
        self.__emap = {}

    def get_mismatch_list(self, xid):
        mismatch_list = []
        if xid in self.__map:
            hdr = self.__map[xid]
            deq_rid = hdr.deq_rid
            if deq_rid >= 0:
                self.__emap.unlock(deq_rid)
                del self.__emap[deq_rid]
            else:
                mismatch_list.append(hex(deq_rid))
            del self.__map[xid]
        return mismatch_list

def analyze_journal_files(xids, analyzer):
    result = {}
    for xid in xids:
        mismatch_list = analyzer.get_mismatch_list(xid)
        result[xid] = mismatch_list
    return result
```
